13.2 Types of Presentations to Inform

Learning objective.

• Provide examples of four main types of speech to inform.

Speaking to inform may fall into one of several categories. The presentation to inform may be

• an explanation,
• a description, or
• a demonstration of how to do something.

Let’s explore each of these types of informative speech.

Explanation

Have you ever listened to a lecture or speech where you just didn’t get it? It wasn’t that you weren’t interested, at least not at first. Perhaps the professor used language and jargon, or gave a confusing example, or omitted something that would have linked facts or concepts together. Soon you probably lost interest and sat there, attending the speech or lecture in body but certainly not in mind. An effective speech to inform will take a complex topic or issue and explain it to the audience in ways that increase audience understanding. Perhaps the speech where you felt lost lacked definitions upfront, or a clear foundation in the introduction. You certainly didn’t learn much, and that’s exactly what you want to avoid when you address your audience. Consider how you felt and then find ways to explain your topic—visually, using definitions and examples, providing a case study—that can lay a foundation on common ground with your audience and build on it.

No one likes to feel left out. As the speaker, it’s your responsibility to ensure that this doesn’t happen. Also know that to teach someone something new—perhaps a skill that they did not posses or a perspective that allows them to see new connections—is a real gift, both to you and the audience members. You will feel rewarded because you made a difference and they will perceive the gain in their own understanding.

As a business communicator, you may be called upon to give an informative report where you communicate status, trends, or relationships that pertain to a specific topic. You might have only a few moments to speak, and you may have to prepare within a tight time frame. Your listeners may want “just the highlights,” only to ask pointed questions that require significant depth and preparation on your part. The informative report is a speech where you organize your information around key events, discoveries, or technical data and provide context and illustration for your audience. They may naturally wonder, “Why are sales up (or down)?” or “What is the product leader in your lineup?” and you need to anticipate their perspective and present the key information that relates to your topic. If everyone in the room knows the product line, you may not need much information about your best seller, but instead place emphasis on marketing research that seems to indicate why it is the best seller.

Perhaps you are asked to be the scout and examine a new market, developing strategies to penetrate it. You’ll need to orient your audience and provide key information about the market and demonstrate leadership as you articulate your strategies. You have a perspective gained by time and research, and your audience wants to know why you see things the way you do, as well as learn what you learned. A status report may be short or long, and may be an update that requires little background, but always consider the audience and what common ground you are building your speech on.

Description

Have you ever listened to a friend tell you about their recent trip somewhere and found the details fascinating, making you want to travel there or visit a similar place? Or perhaps you listened to your chemistry teacher describe a chemical reaction you were going to perform in class and you understood the process and could reasonably anticipate the outcome. Describing information requires emphasis on language that is vivid, captures attention, and excites the imagination. Your audience will be drawn to your effective use of color, descriptive language, and visual aids. An informative speech that focuses description will be visual in many ways. You may choose to illustrate with images, video and audio clips, and maps. Your first-person experience combined with your content will allow the audience to come to know a topic, area, or place through you, or secondhand. Their imagination is your ally, and you should aim to stimulate it with attention-getting devices and clear visual aids. Use your imagination to place yourself in their perspective: how would you like to have someone describe the topic to you?

Demonstration

You want to teach the audience how to throw a fast pitch in softball or a curveball in baseball. You want to demonstrate how to make salsa or how to program the applications on a smartphone. Each of these topics will call on your kindergarten experience of “show and tell.” A demonstrative speech focuses on clearly showing a process and telling the audience important details about each step so that they can imitate, repeat, or do the action themselves. If the topic is complicated, think of ways to simplify each step.

Consider the visual aids or supplies you will need. You may have noticed that cooking shows on television rarely show the chef chopping and measuring ingredients during the demonstration. Instead, the ingredients are chopped and measured ahead of time and the chef simply adds each item to the dish with a brief comment like, “Now we’ll stir in half a cup of chicken stock.” If you want to present a demonstration speech on the ways to make a paper airplane, one that will turn left or right, go up, down or in loops, consider how best to present your topic. Perhaps by illustrating the process of making one airplane followed by example on how to make adjustments to the plane to allow for different flight patterns would be effective. Would you need additional paper airplanes made in advance of your speech? Would an example of the paper airplane in each of the key stages of production be helpful to have ready before the speech? Having all your preparation done ahead of time can make a world of difference, and your audience will appreciate your thoughtful approach.

By considering each step and focusing on how to simplify it, you can understand how the audience might grasp the new information and how you can best help them. Also, consider the desired outcome; for example, will your listeners be able to actually do the task themselves or will they gain an appreciation of the complexities of a difficult skill like piloting an airplane to a safe landing? Regardless of the sequence or pattern you will illustrate or demonstrate, consider how people from your anticipated audience will respond, and budget additional time for repetition and clarification.

Informative presentations come in all sizes, shapes, and forms. You may need to create an “elevator speech” style presentation with the emphasis on brevity, or produce a comprehensive summary of several points that require multiple visual aids to communicate complex processes or trends. The main goal in an informative presentation is to inform, not to persuade, and that requires an emphasis on credibility, for the speaker and the data or information presented. Extra attention to sources is required and you’ll need to indicate what reports, texts, or Web sites were sources for your analysis and conclusions.

Here are additional, more specific types of informative presentations:

• Biographical information
• Case study results
• Comparative advantage results
• Cost-benefit analysis results
• Feasibility studies
• Field study results
• Financial trends analysis
• Health, safety, and accident rates
• Instruction guidelines
• Laboratory results
• Product or service orientations
• Progress reports
• Research results
• Technical specifications

Depending on the rhetorical situation, the audience, and the specific information to be presented, any of these types of presentation may be given as an explanation, a report, a description, or a demonstration.

Key Takeaway

An informative speech may explain, report, describe, or demonstrate how to do something.

• Watch a “how-to” television show, such as one about cooking, home improvement, dog training, or crime solving. What informative techniques and visual aids are used in the show to help viewers learn the skills that are being demonstrated?
• Prepare a simple “how-to” presentation for the class. Present and compare your results.
• Compare and contrast two television programs, noting how each communicates the meaning via visual communication rather than words or dialogue. Share and compare with classmates.

Informative Speeches — Types, Topics, and Examples

What is an informative speech.

An informative speech uses descriptions, demonstrations, and strong detail to explain a person, place, or subject. An informative speech makes a complex topic easier to understand and focuses on delivering information, rather than providing a persuasive argument.

Types of informative speeches

The most common types of informative speeches are definition, explanation, description, and demonstration.

A definition speech explains a concept, theory, or philosophy about which the audience knows little. The purpose of the speech is to inform the audience so they understand the main aspects of the subject matter.

An explanatory speech presents information on the state of a given topic. The purpose is to provide a specific viewpoint on the chosen subject. Speakers typically incorporate a visual of data and/or statistics.

The speaker of a descriptive speech provides audiences with a detailed and vivid description of an activity, person, place, or object using elaborate imagery to make the subject matter memorable.

A demonstrative speech explains how to perform a particular task or carry out a process. These speeches often demonstrate the following:

How to do something

How to make something

How to fix something

How something works

How to write an informative speech

Regardless of the type, every informative speech should include an introduction, a hook, background information, a thesis, the main points, and a conclusion.

Introduction

An attention grabber or hook draws in the audience and sets the tone for the speech. The technique the speaker uses should reflect the subject matter in some way (i.e., if the topic is serious in nature, do not open with a joke). Therefore, when choosing an attention grabber, consider the following:

What’s the topic of the speech?

What’s the occasion?

Who’s the audience?

What’s the purpose of the speech?

Common Attention Grabbers (Hooks)

Ask a question that allows the audience to respond in a non-verbal way (e.g., a poll question where they can simply raise their hands) or ask a rhetorical question that makes the audience think of the topic in a certain way yet requires no response.

Incorporate a well-known quote that introduces the topic. Using the words of a celebrated individual gives credibility and authority to the information in the speech.

Offer a startling statement or information about the topic, which is typically done using data or statistics. The statement should surprise the audience in some way.

Provide a brief anecdote that relates to the topic in some way.

Present a “what if” scenario that connects to the subject matter of the speech.

Identify the importance of the speech’s topic.

Starting a speech with a humorous statement often makes the audience more comfortable with the speaker.

Include any background information pertinent to the topic that the audience needs to know to understand the speech in its entirety.

The thesis statement shares the central purpose of the speech.

Demonstrate

Preview the main ideas that will help accomplish the central purpose. Typically, informational speeches will have an average of three main ideas.

Body paragraphs

Apply the following to each main idea (body) :

Identify the main idea ( NOTE: The main points of a demonstration speech would be the individual steps.)

Provide evidence to support the main idea

Explain how the evidence supports the main idea/central purpose

Transition to the next main idea

Review or restate the thesis and the main points presented throughout the speech.

Much like the attention grabber, the closing statement should interest the audience. Some of the more common techniques include a challenge, a rhetorical question, or restating relevant information:

Provide the audience with a challenge or call to action to apply the presented information to real life.

Detail the benefit of the information.

Close with an anecdote or brief story that illustrates the main points.

Leave the audience with a rhetorical question to ponder after the speech has concluded.

Detail the relevance of the presented information.

Before speech writing, brainstorm a list of informative speech topic ideas. The right topic depends on the type of speech, but good topics can range from video games to disabilities and electric cars to healthcare and mental health.

Informative speech topics

Some common informative essay topics for each type of informational speech include the following:

Informative speech examples

Week 10: Rhetorical Communications

Types of informative speeches, learning objectives.

• Identify several categories of topics that may be used in informative speaking.
• Describe several approaches to developing a topic.

For some speakers, deciding on a topic is one of the most difficult parts of informative speaking. The following subsections begin by discussing several categories of topics that you might use for an informative presentation. Then we discuss how you might structure your speech to address potential audience difficulties in understanding your topic or information.

The term “objects” encompasses many topics we might not ordinarily consider to be “things.” It’s a category that includes people, institutions, places, substances, and inanimate things. The following are some of these topics:

• Mitochondria
• Dream catchers
• Hubble telescope
• Seattle’s Space Needle
• Silicon chip
• Spruce Goose
• Medieval armor
• DDT insecticide

You will find it necessary to narrow your topic about an object because, like any topic, you can’t say everything about it in a single speech. In most cases, there are choices about how to narrow the topic. Here are some specific purpose statements that reflect ways of narrowing a few of those topics:

• To inform the audience about the role of soy inks in reducing toxic pollution
• To inform the audience about the current uses of the banned insecticide DDT
• To inform the audience about what we’ve learned from the Hubble telescope
• To inform the audience about the role of the NAACP in the passage of the Civil Rights Act of 1964
• To describe the significance of the gigantic Spruce Goose, the wooden airplane that launched an airline

These specific purposes reflect a narrow, but interesting, approach to each topic. These purposes are precise, and they should help you maintain your focus on a narrow but deep slice of knowledge.

This category applies both to specific individuals and also to roles. The following are some of these topics:

• Dalai Lamas
• Tsar Nicholas II
• Modern midwives
• Catherine the Great
• Navajo code talkers
• Mahatma Gandhi
• Justice Thurgood Marshall
• Madame Curie
• Leopold Mozart
• The Hemlock Society
• Sonia Sotomayor
• Jack the Ripper

There is a great deal of information about each one of these examples. In order to narrow the topic or write a thesis statement, it’s important to recognize that your speech should not be a biography, or time line, of someone’s life. If you attempt to deliver a comprehensive report of every important event and accomplishment related to your subject, then nothing will seem any more important than anything else. To capture and hold your audience’s interest, you must narrow to a focus on a feature, event, achievement, or secret about your human topic.

Here are some purpose statements that reflect a process of narrowing:

• To inform the audience about the training program undergone by the first US astronauts to land on the moon
• To inform the audience about how a young Dalai Lama is identified
• To inform the audience about why Gandhi was regarded as a mahatma, or “great heart”
• To inform the audience about the extensive scientific qualifications of modern midwives

Without a limited purpose, you will find, with any of these topics, that there’s simply too much to say. Your purpose statement will be a strong decision-making tool about what to include in your speech.

An event can be something that occurred only once, or an event that is repeated:

• The murder of Emmett Till
• The Iditarod Dogsled Race
• The Industrial Revolution
• The discovery of the smallpox vaccine
• The Bikini Atoll atomic bomb tests
• The Bay of Pigs
• The Super Bowl
• The Academy Awards

Again, we find that any of these topics must be carefully narrowed in order to build a coherent speech. Failure to do so will result in a shallow speech. Here are a few ways to narrow the purpose:

• To explain how the murder of Emmett Till helped energize the civil rights movement
• To describe how the Industrial Revolution affected the lives of ordinary people
• To inform the audience about the purpose of the Iditarod dogsled race

There are many ways to approach any of these and other topics, but again, you must emphasize an important dimension of the event. Otherwise, you run the risk of producing a time line in which the main point gets lost. In a speech about an event, you may use a chronological order , but if you choose to do so, you can’t include every detail. The following is an example:

Specific Purpose: To inform the audience about the purpose of the Iditarod dogsled race.

Central Idea: The annual Iditarod commemorates the heroism of Balto, the sled dog that led a dog team carrying medicine 1150 miles to save Nome from an outbreak of diphtheria.

Main Points:

• Diphtheria broke out in a remote Alaskan town.
• Dogsleds were the only transportation for getting medicine.
• The Iditarod Trail was long, rugged, and under siege of severe weather.
• Balto the dog knew where he was going, even when the musher did not.
• The annual race commemorates Balto’s heroism in saving the lives of the people of Nome.

In this example, you must explain the event. However, another way to approach the same event would describe it. The following is an example:

Specific Purpose: To describe the annual Iditarod Trail Sled Dog Race.

Central Idea: It’s a long and dangerous race.

• The 1150-mile, ten- to seventeen-day race goes through wilderness with widely spaced checkpoints for rest, first aid, and getting fresh dogs.
• A musher, or dogsled driver, must be at least fourteen years old to endure the rigors of severe weather, exhaustion, and loneliness.
• A musher is responsible for his or her own food, food for twelve to sixteen dogs, and for making sure they don’t get lost.
• Reaching the end of the race without getting lost, even in last place, is considered honorable and heroic.
• The expense of participation is greater than the prize awarded to the winner.

By now you can see that there are various ways to approach a topic while avoiding an uninspiring time line. In the example of the Iditarod race, you could alternatively frame it as an Alaskan tourism topic, or you could emphasize the enormous staff involved in first aid, search and rescue, dog care, trail maintenance, event coordination, financial management, and registration.

Concepts are abstract ideas that exist independent of whether they are observed or practiced, such as the example of social equality that follows. Concepts can include hypotheses and theories.

• The glass ceiling
• Ethnocentrism
• Honor codes
• Fairness theory
• The American Dream
• Social equality

Here are a few examples of specific purposes developed from the examples:

• To explain why people in all cultures are ethnocentric
• To describe the Hindu concept of karma
• To distinguish the differences between the concepts of wellness and health
• To show the resources available in our local school system for children with autism
• To explain three of Dr. Stephen Suranovic’s seven categories of fairness

Here is one possible example of a way to develop one of these topics:

Specific Purpose: To explain why people in all cultures are ethnocentric.

Central Idea: There are benefits to being ethnocentric.

• Ethnocentrism is the idea that one’s own culture is superior to others.
• Ethnocentrism strongly contributes to positive group identity.
• Ethnocentrism facilitates the coordination of social activity.
• Ethnocentrism contributes to a sense of safety within a group.
• Ethnocentrism becomes harmful when it creates barriers.

In an example of a concept about which people disagree, you must represent multiple and conflicting views as fully and fairly as possible. For instance:

Specific Purpose: To expose the audience to three different views of the American Dream.

Central Idea: The American Dream is a shared dream, an impossible dream, or a dangerous dream, depending on the perspective of the individual.

• The concept of the American Dream describes a state of abundant well-being in which an honest and productive American can own a home; bring up a family; work at a permanent, well-paying job with benefits; and retire in security and leisure.
• Many capitalists support the social pattern of working hard to deserve and acquire the material comforts and security of a comfortable life.
• Many sociologists argue that the American Dream is far out of reach for the 40 percent of Americans at the bottom of the economic scale.
• Many environmentalists argue that the consumption patterns that accompany the American Dream have resulted in the depletion of resources and the pollution of air, water, and soil.

If your speech topic is a process, your goal should be to help your audience understand it, or be able to perform it. In either instance, processes involve a predictable series of changes, phases, or steps.

• Soil erosion
• Cell division
• Physical therapy
• Volcanic eruption
• Paper recycling
• Consumer credit evaluations
• Scholarship money searches
• Navy Seal training
• Portfolio building
• The development of Alzheimer’s disease

For some topics, you will need presentation aids in order to make your meaning clear to your listeners. Even in cases where you don’t absolutely need a presentation aid, one might be useful. For instance, if your topic is evaluating consumer credit, instead of just describing a comparison between two different interest rates applied to the same original amount of debt, it would be helpful to show a graph of the difference. This might also be the sort of topic that would strongly serve the needs of your audience before they find themselves in trouble. Since this will be an informative speech, you must resist the impulse to tell your listeners that one form of borrowing is good and another is bad; you must simply show them the difference in numbers. They can reach their own conclusions.

Organizing your facts is crucially important when discussing a process. Every stage of a process must be clear and understandable. When two or more things occur at the same time, as they might in the development of Alzheimer’s disease, it is important to make it clear that several things are occurring at once. For example, as plaque is accumulating in the brain, the patient is likely to begin exhibiting various symptoms.

Here’s an example of the initial steps of a speech about a process:

Specific Purpose: To inform the audience about how to build an academic portfolio.

Central Idea: A portfolio represents you and emphasizes your best skills.

• A portfolio is an organized selection containing the best examples of the skills you can offer an employer.
• A portfolio should contain samples of a substantial body of written work, print and electronically published pieces, photography, and DVDs of your media productions.
• A portfolio should be customized for each prospective employer.
• The material in your portfolio should be consistent with the skills and experience in your résumé.

In a speech about the process of building a portfolio, there will be many smaller steps to include within each of the main points. For instance, creating separate sections of the portfolio for different types of creative activities, writing a table of contents, labeling and dating your samples, making your samples look attractive and professional, and other steps should be inserted where it makes the most sense, in the most organized places, in order to give your audience the most coherent understanding possible.

You’ve probably noticed that there are topics that could be appropriate in more than one category. For instance, the 1980 eruption of Mt. St. Helen’s could be legitimately handled as an event or as a process. If you approach the eruption as an event, most of the information you include will focus on human responses and the consequences on humans and the landscape. If you approach the eruption as a process, you will be using visual aids and explanations to describe geological changes before and during the eruption. You might also approach this topic from the viewpoint of a person whose life was affected by the eruption. This should remind you that there are many ways to approach most topics, and because of that, your narrowing choices and your purpose will be the important foundation determining the structure of your informative speech.

Developing Your Topic for the Audience

One issue to consider when preparing an informative speech is how best to present the information to enhance audience learning. Katherine Rowan suggests focusing on areas where your audience may experience confusion and using the likely sources of confusion as a guide for developing the content of your speech. Rowan identifies three sources of audience confusion: difficult concepts or language, difficult-to-envision structures or processes, and ideas that are difficult to understand because they are hard to believe. [1] The following subsections will discuss each of these and will provide strategies for dealing with each of these sources of confusion.

Difficult Concepts or Language

Sometimes audiences may have difficulty understanding information because of the concepts or language used. For example, they may not understand what the term “organic food” means or how it differs from “all-natural” foods. If an audience is likely to experience confusion over a basic concept or term, Rowan suggests using an elucidating explanation composed of four parts. The purpose of such an explanation is to clarify the meaning and use of the concept by focusing on essential features of the concept.

The first part of an elucidating explanation is to provide a typical exemplar, or example that includes all the central features of the concept. If you are talking about what is fruit, an apple or orange would be a typical exemplar.

The second step Rowan suggests is to follow up the typical exemplar with a definition. Fruits might be defined as edible plant structures that contain the seeds of the plant.

After providing a definition, you can move on to the third part of the elucidating explanation: providing a variety of examples and nonexamples. Here is where you might include less typical examples of fruit, such as avocados, squash, or tomatoes, and foods, such as rhubarb, which is often treated as a fruit but is not by definition.

Fourth, Rowan suggests concluding by having the audience practice distinguishing examples from nonexamples. In this way, the audience leaves the speech with a clear understanding of the concept.

Difficult-to-Envision Processes or Structures

A second source of audience difficulty in understanding, according to Rowan, is a process or structure that is complex and difficult to envision. The blood circulation system in the body might be an example of a difficult-to-envision process. To address this type of audience confusion, Rowan suggests a quasi-scientific explanation, which starts by giving a big-picture perspective on the process. Presentation aids or analogies might be helpful in giving an overview of the process. For the circulatory system, you could show a video or diagram of the entire system or make an analogy to a pump. Then you can move to explaining relationships among the components of the process. Be sure when you explain relationships among components that you include transition and linking words like “leads to” and “because” so that your audience understands relationships between concepts. You may remember the childhood song describing the bones in the body with lines such as, “the hip bone’s connected to the thigh bone; the thigh bone’s connected to the knee bone.” Making the connections between components helps the audience to remember and better understand the process.

Difficult to Understand because It’s Hard to Believe

A third source of audience confusion, and perhaps the most difficult to address as a speaker, is an idea that’s difficult to understand because it’s hard to believe. This often happens when people have implicit, but erroneous, theories about how the world works. For example, the idea that science tries to disprove theories is difficult for some people to understand; after all, shouldn’t the purpose of science be to prove things? In such a case, Rowan suggests using a transformative explanation. A transformative explanation begins by discussing the audience’s implicit theory and showing why it is plausible. Then you move to showing how the implicit theory is limited and conclude by presenting the accepted explanation and why that explanation is better. In the case of scientists disproving theories, you might start by talking about what science has proven (e.g., the causes of malaria, the usefulness of penicillin in treating infection) and why focusing on science as proof is a plausible way of thinking. Then you might show how the science as proof theory is limited by providing examples of ideas that were accepted as “proven” but were later found to be false, such as the belief that diseases are caused by miasma, or “bad air”; or that bloodletting cures diseases by purging the body of “bad humors.” You can then conclude by showing how science is an enterprise designed to disprove theories and that all theories are accepted as tentative in light of existing knowledge.

Rowan’s framework is helpful because it keeps our focus on the most important element of an informative speech: increasing audience understanding about a topic.

Honesty and credibility must undergird your presentation; otherwise, they betray the trust of your listeners. Therefore, if you choose a topic that turns out to be too difficult, you must decide what will serve the needs and interests of the audience. Shortcuts and oversimplifications are not the answer.

Being ethical often involves a surprising amount of work. In the case of choosing too ambitious a topic, you have some choices:

• Narrow your topic further.
• Narrow your topic in a different way.
• Reconsider your specific purpose.
• Start over with a new topic.

Your goal is to serve the interests and needs of your audience, whoever they are and whether you believe they already know something about your topic.

Key Takeaways

• A variety of different topic categories are available for informative speaking.
• One way to develop your topic is to focus on areas that might be confusing to the audience. If the audience is likely to be confused about language or a concept, an elucidating explanation might be helpful. If a process is complex, a quasi-scientific explanation may help. If the audience already has an erroneous implicit idea of how something works then a transformative explanation might be needed.
• Choose a topic such as “American Education in the Twenty-First Century.” Write a new title for that speech for each of the following audiences: financial managers, first-year college students, parents of high school students, nuns employed in Roman Catholic schools, psychotherapists, and teamsters. Write a specific purpose for the speech for each of these audiences.
• Think about three potential topics you could use for an informative speech. Identify where the audience might experience confusion with concepts, processes, or preexisting implicit theories. Select one of the topics and outline how you would develop the topic to address the audience’s potential confusion.

13.2 Types of Presentations to Inform

Learning objective.

• Provide examples of four main types of speech to inform.

Speaking to inform may fall into one of several categories. The presentation to inform An explanation, a report, a description, or a demonstration of how to do something. may be

• an explanation,
• a description, or
• a demonstration of how to do something.

Let’s explore each of these types of informative speech.

Explanation

Have you ever listened to a lecture or speech where you just didn’t get it? It wasn’t that you weren’t interested, at least not at first. Perhaps the professor used language and jargon, or gave a confusing example, or omitted something that would have linked facts or concepts together. Soon you probably lost interest and sat there, attending the speech or lecture in body but certainly not in mind. An effective speech to inform will take a complex topic or issue and explain it to the audience in ways that increase audience understanding. Perhaps the speech where you felt lost lacked definitions upfront, or a clear foundation in the introduction. You certainly didn’t learn much, and that’s exactly what you want to avoid when you address your audience. Consider how you felt and then find ways to explain your topic—visually, using definitions and examples, providing a case study—that can lay a foundation on common ground with your audience and build on it.

No one likes to feel left out. As the speaker, it’s your responsibility to ensure that this doesn’t happen. Also know that to teach someone something new—perhaps a skill that they did not posses or a perspective that allows them to see new connections—is a real gift, both to you and the audience members. You will feel rewarded because you made a difference and they will perceive the gain in their own understanding.

As a business communicator, you may be called upon to give an informative report where you communicate status, trends, or relationships that pertain to a specific topic. You might have only a few moments to speak, and you may have to prepare within a tight time frame. Your listeners may want “just the highlights,” only to ask pointed questions that require significant depth and preparation on your part. The informative report is a speech where you organize your information around key events, discoveries, or technical data and provide context and illustration for your audience. They may naturally wonder, “Why are sales up (or down)?” or “What is the product leader in your lineup?” and you need to anticipate their perspective and present the key information that relates to your topic. If everyone in the room knows the product line, you may not need much information about your best seller, but instead place emphasis on marketing research that seems to indicate why it is the best seller.

Perhaps you are asked to be the scout and examine a new market, developing strategies to penetrate it. You’ll need to orient your audience and provide key information about the market and demonstrate leadership as you articulate your strategies. You have a perspective gained by time and research, and your audience wants to know why you see things the way you do, as well as learn what you learned. A status report may be short or long, and may be an update that requires little background, but always consider the audience and what common ground you are building your speech on.

Description

Have you ever listened to a friend tell you about their recent trip somewhere and found the details fascinating, making you want to travel there or visit a similar place? Or perhaps you listened to your chemistry teacher describe a chemical reaction you were going to perform in class and you understood the process and could reasonably anticipate the outcome. Describing information requires emphasis on language that is vivid, captures attention, and excites the imagination. Your audience will be drawn to your effective use of color, descriptive language, and visual aids. An informative speech that focuses description will be visual in many ways. You may choose to illustrate with images, video and audio clips, and maps. Your first-person experience combined with your content will allow the audience to come to know a topic, area, or place through you, or secondhand. Their imagination is your ally, and you should aim to stimulate it with attention-getting devices and clear visual aids. Use your imagination to place yourself in their perspective: how would you like to have someone describe the topic to you?

Demonstration

You want to teach the audience how to throw a fast pitch in softball or a curveball in baseball. You want to demonstrate how to make salsa or how to program the applications on a smartphone. Each of these topics will call on your kindergarten experience of “show and tell.” A demonstrative speech focuses on clearly showing a process and telling the audience important details about each step so that they can imitate, repeat, or do the action themselves. If the topic is complicated, think of ways to simplify each step.

Consider the visual aids or supplies you will need. You may have noticed that cooking shows on television rarely show the chef chopping and measuring ingredients during the demonstration. Instead, the ingredients are chopped and measured ahead of time and the chef simply adds each item to the dish with a brief comment like, “Now we’ll stir in half a cup of chicken stock.” If you want to present a demonstration speech on the ways to make a paper airplane, one that will turn left or right, go up, down or in loops, consider how best to present your topic. Perhaps by illustrating the process of making one airplane followed by example on how to make adjustments to the plane to allow for different flight patterns would be effective. Would you need additional paper airplanes made in advance of your speech? Would an example of the paper airplane in each of the key stages of production be helpful to have ready before the speech? Having all your preparation done ahead of time can make a world of difference, and your audience will appreciate your thoughtful approach.

By considering each step and focusing on how to simplify it, you can understand how the audience might grasp the new information and how you can best help them. Also, consider the desired outcome; for example, will your listeners be able to actually do the task themselves or will they gain an appreciation of the complexities of a difficult skill like piloting an airplane to a safe landing? Regardless of the sequence or pattern you will illustrate or demonstrate, consider how people from your anticipated audience will respond, and budget additional time for repetition and clarification.

Informative presentations come in all sizes, shapes, and forms. You may need to create an “elevator speech” style presentation with the emphasis on brevity, or produce a comprehensive summary of several points that require multiple visual aids to communicate complex processes or trends. The main goal in an informative presentation is to inform, not to persuade, and that requires an emphasis on credibility, for the speaker and the data or information presented. Extra attention to sources is required and you’ll need to indicate what reports, texts, or Web sites were sources for your analysis and conclusions.

Here are additional, more specific types of informative presentations:

• Biographical information
• Case study results
• Comparative advantage results
• Cost-benefit analysis results
• Feasibility studies
• Field study results
• Financial trends analysis
• Health, safety, and accident rates
• Instruction guidelines
• Laboratory results
• Product or service orientations
• Progress reports
• Research results
• Technical specifications

Depending on the rhetorical situation, the audience, and the specific information to be presented, any of these types of presentation may be given as an explanation, a report, a description, or a demonstration.

Key Takeaway

An informative speech may explain, report, describe, or demonstrate how to do something.

• Watch a “how-to” television show, such as one about cooking, home improvement, dog training, or crime solving. What informative techniques and visual aids are used in the show to help viewers learn the skills that are being demonstrated?
• Prepare a simple “how-to” presentation for the class. Present and compare your results.
• Compare and contrast two television programs, noting how each communicates the meaning via visual communication rather than words or dialogue. Share and compare with classmates.

8 Different types of presentations every presenter must know

How do i choose the right type of presentation for my topic or audience, types of presentation faq, 5 steps to create a presentation with venngage .

When it comes to presentations, versatility is the name of the game. Having a variety of presentation styles up your sleeve can make a world of difference in keeping your audience engaged. Here are 8 essential presentation types that every presenter should be well-acquainted with:

1. Informative presentation

Ever sat through a presentation that left you feeling enlightened? That’s the power of an informative presentation. 

This presentation style is all about sharing knowledge and shedding light on a particular topic. Whether you’re diving into the depths of quantum physics or explaining the intricacies of the latest social media trends, informative presentations aim to increase the audience’s understanding.

When delivering an informative presentation, simplify complex topics with clear visuals and relatable examples. Organize your content logically, starting with the basics and gradually delving deeper and always remember to keep jargon to a minimum and encourage questions for clarity.

Academic presentations and research presentations are great examples of informative presentations. An effective academic presentation involves having clear structure, credible evidence, engaging delivery and supporting visuals. Provide context to emphasize the topic’s significance, practice to perfect timing, and be ready to address anticipated questions. 

2. Persuasive presentation

If you’ve ever been swayed by a passionate speaker armed with compelling arguments, you’ve experienced a persuasive presentation . 

This type of presentation is like a verbal tug-of-war, aiming to convince the audience to see things from a specific perspective. Expect to encounter solid evidence, logical reasoning and a dash of emotional appeal.

With persuasive presentations, it’s important to know your audience inside out and tailor your message to their interests and concerns. Craft a compelling narrative with a strong opening, a solid argument and a memorable closing. Additionally, use visuals strategically to enhance your points.

Examples of persuasive presentations include presentations for environmental conservations, policy change, social issues and more. Here are some engaging presentation templates you can use to get started with: 

3. Demonstration or how-to presentation

A Demonstration or How-To Presentation is a type of presentation where the speaker showcases a process, technique, or procedure step by step, providing the audience with clear instructions on how to replicate the demonstrated action. 

A demonstrative presentation is particularly useful when teaching practical skills or showing how something is done in a hands-on manner.

These presentations are commonly used in various settings, including educational workshops, training sessions, cooking classes, DIY tutorials, technology demonstrations and more. Designing creative slides for your how-to presentations can heighten engagement and foster better information retention. 

Speakers can also consider breaking down the process into manageable steps, using visual aids, props and sometimes even live demonstrations to illustrate each step. The key is to provide clear and concise instructions, engage the audience with interactive elements and address any questions that may arise during the presentation.

4. Training or instructional presentation

Training presentations are geared towards imparting practical skills, procedures or concepts — think of this as the more focused cousin of the demonstration presentation. 

Whether you’re teaching a group of new employees the ins and outs of a software or enlightening budding chefs on the art of soufflé-making, training presentations are all about turning novices into experts.

To maximize the impact of your training or instructional presentation, break down complex concepts into digestible segments. Consider using real-life examples to illustrate each point and create a connection. 

You can also create an interactive presentation by incorporating elements like quizzes or group activities to reinforce understanding.

5. Sales presentation

Sales presentations are one of the many types of business presentations and the bread and butter of businesses looking to woo potential clients or customers. With a sprinkle of charm and a dash of persuasion, these presentations showcase products, services or ideas with one end goal in mind: sealing the deal.

A successful sales presentation often has key characteristics such as a clear value proposition, strong storytelling, confidence and a compelling call to action. Hence, when presenting to your clients or stakeholders, focus on benefits rather than just features. 

Anticipate and address potential objections before they arise and use storytelling to showcase how your offering solves a specific problem for your audience. Utilizing visual aids is also a great way to make your points stand out and stay memorable.

A sales presentation can be used to promote service offerings, product launches or even consultancy proposals that outline the expertise and industry experience of a business. Here are some template examples you can use for your next sales presentation:

6. Pitch presentation

Pitch presentations are your ticket to garnering the interest and support of potential investors, partners or stakeholders. Think of your pitch deck as your chance to paint a vivid picture of your business idea or proposal and secure the resources you need to bring it to life. 

Business presentations aside, individuals can also create a portfolio presentation to showcase their skills, experience and achievements to potential clients, employers or investors. 

Craft a concise and compelling narrative. Clearly define the problem your idea solves and how it stands out in the market. Anticipate questions and practice your answers. Project confidence and passion for your idea.

7. Motivational or inspirational presentation

Feeling the need for a morale boost? That’s where motivational presentations step in. These talks are designed to uplift and inspire, often featuring personal anecdotes, heartwarming stories and a generous serving of encouragement.

Form a connection with your audience by sharing personal stories that resonate with your message. Use a storytelling style with relatable anecdotes and powerful metaphors to create an emotional connection. Keep the energy high and wrap up your inspirational presentations with a clear call to action.

Inspirational talks and leadership presentations aside, a motivational or inspirational presentation can also be a simple presentation aimed at boosting confidence, a motivational speech focused on embracing change and more.

8. Status or progress report presentation

Projects and businesses are like living organisms, constantly evolving and changing. Status or progress report presentations keep everyone in the loop by providing updates on achievements, challenges and future plans. It’s like a GPS for your team, ensuring everyone stays on track.

Be transparent about achievements, challenges and future plans. Utilize infographics, charts and diagrams to present your data visually and simplify information. By visually representing data, it becomes easier to identify trends, make predictions and strategize based on evidence.

Now that you’ve learned about the different types of presentation methods and how to use them, you’re on the right track to creating a good presentation that can boost your confidence and enhance your presentation skills . 

Selecting the most suitable presentation style is akin to choosing the right outfit for an occasion – it greatly influences how your message is perceived. Here’s a more detailed guide to help you make that crucial decision:

1. Define your objectives

Begin by clarifying your presentation’s goals. Are you aiming to educate, persuade, motivate, train or perhaps sell a concept? Your objectives will guide you to the most suitable presentation type. 

For instance, if you’re aiming to inform, an informative presentation would be a natural fit. On the other hand, a persuasive presentation suits the goal of swaying opinions.

2. Know your audience

Regardless if you’re giving an in-person or a virtual presentation — delve into the characteristics of your audience. Consider factors like their expertise level, familiarity with the topic, interests and expectations. 

If your audience consists of professionals in your field, a more technical presentation might be suitable. However, if your audience is diverse and includes newcomers, an approachable and engaging style might work better.

3. Analyze your content

Reflect on the content you intend to present. Is it data-heavy, rich in personal stories or focused on practical skills? Different presentation styles serve different content types. 

For data-driven content, an informative or instructional presentation might work best. For emotional stories, a motivational presentation could be a compelling choice.

4. Consider time constraints

Evaluate the time you have at your disposal. If your presentation needs to be concise due to time limitations, opt for a presentation style that allows you to convey your key points effectively within the available timeframe. A pitch presentation, for example, often requires delivering impactful information within a short span.

5. Leverage visuals

Visual aids are powerful tools in presentations. Consider whether your content would benefit from visual representation. If your PowerPoint presentations involve step-by-step instructions or demonstrations, a how-to presentation with clear visuals would be advantageous. Conversely, if your content is more conceptual, a motivational presentation could rely more on spoken words.

6. Align with the setting

Take the presentation environment into account. Are you presenting in a formal business setting, a casual workshop or a conference? Your setting can influence the level of formality and interactivity in your presentation. For instance, a demonstration presentation might be ideal for a hands-on workshop, while a persuasive presentation is great for conferences.

7. Gauge audience interaction

Determine the level of audience engagement you want. Interactive presentations work well for training sessions, workshops and small group settings, while informative or persuasive presentations might be more one-sided.

8. Flexibility

Stay open to adjusting your presentation style on the fly. Sometimes, unexpected factors might require a change of presentation style. Be prepared to adjust on the spot if audience engagement or reactions indicate that a different approach would be more effective.

Remember that there is no one-size-fits-all approach, and the best type of presentation may vary depending on the specific situation and your unique communication goals. By carefully considering these factors, you can choose the most effective presentation type to successfully engage and communicate with your audience.

To save time, use a presentation software or check out these presentation design and presentation background guides to create a presentation that stands out.    

What are some effective ways to begin and end a presentation?

Capture your audience’s attention from the start of your presentation by using a surprising statistic, a compelling story or a thought-provoking question related to your topic. 

To conclude your presentation , summarize your main points, reinforce your key message and leave a lasting impression with a powerful call to action or a memorable quote that resonates with your presentation’s theme.

How can I make my presentation more engaging and interactive?

To create an engaging and interactive presentation for your audience, incorporate visual elements such as images, graphs and videos to illustrate your points visually. Share relatable anecdotes or real-life examples to create a connection with your audience. 

You can also integrate interactive elements like live polls, open-ended questions or small group discussions to encourage participation and keep your audience actively engaged throughout your presentation.

Which types of presentations require special markings

Some presentation types require special markings such as how sales presentations require persuasive techniques like emphasizing benefits, addressing objections and using compelling visuals to showcase products or services. 

Demonstrations and how-to presentations on the other hand require clear markings for each step, ensuring the audience can follow along seamlessly. 

That aside, pitch presentations require highlighting unique selling points, market potential and the competitive edge of your idea, making it stand out to potential investors or partners.

Informative Speaking

In this guide, you can learn about the purposes and types of informative speeches, about writing and delivering informative speeches, and about the parts of informative speeches.

Purposes of Informative Speaking

Informative speaking offers you an opportunity to practice your researching, writing, organizing, and speaking skills. You will learn how to discover and present information clearly. If you take the time to thoroughly research and understand your topic, to create a clearly organized speech, and to practice an enthusiastic, dynamic style of delivery, you can be an effective "teacher" during your informative speech. Finally, you will get a chance to practice a type of speaking you will undoubtedly use later in your professional career.

The purpose of the informative speech is to provide interesting, useful, and unique information to your audience. By dedicating yourself to the goals of providing information and appealing to your audience, you can take a positive step toward succeeding in your efforts as an informative speaker.

Major Types of Informative Speeches

In this guide, we focus on informative speeches about:

These categories provide an effective method of organizing and evaluating informative speeches. Although they are not absolute, these categories provide a useful starting point for work on your speech.

In general, you will use four major types of informative speeches. While you can classify informative speeches many ways, the speech you deliver will fit into one of four major categories.

Speeches about Objects

Speeches about objects focus on things existing in the world. Objects include, among other things, people, places, animals, or products.

Because you are speaking under time constraints, you cannot discuss any topic in its entirety. Instead, limit your speech to a focused discussion of some aspect of your topic.

Some example topics for speeches about objects include: the Central Intelligence Agency, tombstones, surgical lasers, Franklin Delano Roosevelt, the pituitary gland, and lemmings.

To focus these topics, you could give a speech about Franklin Delano Roosevelt and efforts to conceal how he suffered from polio while he was in office. Or, a speech about tombstones could focus on the creation and original designs of grave markers.

Speeches about Processes

Speeches about processes focus on patterns of action. One type of speech about processes, the demonstration speech, teaches people "how-to" perform a process. More frequently, however, you will use process speeches to explain a process in broader terms. This way, the audience is more likely to understand the importance or the context of the process.

A speech about how milk is pasteurized would not teach the audience how to milk cows. Rather, this speech could help audience members understand the process by making explicit connections between patterns of action (the pasteurization process) and outcomes (a safe milk supply).

Other examples of speeches about processes include: how the Internet works (not "how to work the Internet"), how to construct a good informative speech, and how to research the job market. As with any speech, be sure to limit your discussion to information you can explain clearly and completely within time constraints.

Speeches about Events

Speeches about events focus on things that happened, are happening, or will happen. When speaking about an event, remember to relate the topic to your audience. A speech chronicling history is informative, but you should adapt the information to your audience and provide them with some way to use the information. As always, limit your focus to those aspects of an event that can be adequately discussed within the time limitations of your assignment.

Examples of speeches about events include: the 1963 Civil Rights March on Washington, Groundhog's Day, the Battle of the Bulge, the World Series, and the 2000 Presidential Elections.

Speeches about Concepts

Speeches about concepts focus on beliefs, ideas, and theories. While speeches about objects, processes, and events are fairly concrete, speeches about concepts are more abstract. Take care to be clear and understandable when creating and presenting a speech about a concept. When selecting a concept, remember you are crafting an informative speech. Often, speeches about concepts take on a persuasive tone. Focus your efforts toward providing unbiased information and refrain from making arguments. Because concepts can be vague and involved, limit your speech to aspects that can be readily explained and understood within the time limits.

Some examples of topics for concept speeches include: democracy, Taoism, principles of feminism, the philosophy of non-violent protest, and the Big Bang theory.

Strategies for Selecting a Topic

In many cases, circumstances will dictate the topic of your speech. However, if the topic has not been assigned or if you are having difficulty figuring out how to frame your topic as an informative speech,the following may be useful.

Begin by thinking of your interests. If you have always loved art, contemplate possible topics dealing with famous artists, art works, or different types of art. If you are employed, think of aspects of your job or aspects of your employer's business that would be interesting to talk about. While you cannot substitute personal experience for detailed research, your own experience can supplement your research and add vitality to your presentation. Choose one of the items below to learn more about selecting a topic.

Learn More about an Unfamiliar Topic

You may benefit more by selecting an unfamiliar topic that interests you. You can challenge yourself by choosing a topic you'd like to learn about and to help others understand it. If the Buddhist religion has always been an interesting and mysterious topic to you, research the topic and create a speech that offers an understandable introduction to the religion. Remember to adapt Buddhism to your audience and tell them why you think this information is useful to them. By taking this approach, you can learn something new and learn how to synthesize new information for your audience.

Think about Previous Classes

You might find a topic by thinking of classes you have taken. Think back to concepts covered in those classes and consider whether they would serve as unique, interesting, and enlightening topics for the informative speech. In astronomy, you learned about red giants. In history, you learned about Napoleon. In political science, you learned about The Federalist Papers. Past classes serve as rich resources for informative speech topics. If you make this choice, use your class notes and textbook as a starting point. To fully develop the content, you will need to do extensive research and perhaps even a few interviews.

Talk to Others

Topic selection does not have to be an individual effort. Spend time talking about potential topics with classmates or friends. This method can be extremely effective because other people can stimulate further ideas when you get stuck. When you use this method, always keep the basic requirements and the audience in mind. Just because you and your friend think home-brew is a great topic does not mean it will enthrall your audience or impress your instructor. While you talk with your classmates or friends, jot notes about potential topics and create a master list when you exhaust the possibilities. From this list, choose a topic with intellectual merit, originality, and potential to entertain while informing.

Framing a Thesis Statement

Once you settle on a topic, you need to frame a thesis statement. Framing a thesis statement allows you to narrow your topic, and in turns allows you to focus your research in this specific area, saving you time and trouble in the process.

Selecting a topic and focusing it into a thesis statement can be a difficult process. Fortunately, a number of useful strategies are available to you.

Thesis Statement Purpose

The thesis statement is crucial for clearly communicating your topic and purpose to the audience. Be sure to make the statement clear, concise, and easy to remember. Deliver it to the audience and use verbal and nonverbal illustrations to make it stand out.

Strategies For Framing a Thesis Statement

Focus on a specific aspect of your topic and phrase the thesis statement in one clear, concise, complete sentence, focusing on the audience. This sentence sets a goal for the speech. For example, in a speech about art, the thesis statement might be: "The purpose of this speech is to inform my audience about the early works of Vincent van Gogh." This statement establishes that the speech will inform the audience about the early works of one great artist. The thesis statement is worded conversationally and included in the delivery of the speech.

Thesis Statement and Audience

The thesis appears in the introduction of the speech so that the audience immediately realizes the speaker's topic and goal. Whatever the topic may be, you should attempt to create a clear, focused thesis statement that stands out and could be repeated by every member of your audience. It is important to refer to the audience in the thesis statement; when you look back at the thesis for direction, or when the audience hears the thesis, it should be clear that the most important goal of your speech is to inform the audience about your topic. While the focus and pressure will be on you as a speaker, you should always remember that the audience is the reason for presenting a public speech.

Avoid being too trivial or basic for the average audience member. At the same time, avoid being too technical for the average audience member. Be sure to use specific, concrete terms that clearly establish the focus of your speech.

Thesis Statement and Delivery

When creating the thesis statement, be sure to use a full sentence and frame that sentence as a statement, not as a question. The full sentence, "The purpose of this speech is to inform my audience about the early works of Vincent van Gogh," provides clear direction for the speech, whereas the fragment "van Gogh" says very little about the purpose of the speech. Similarly, the question "Who was Vincent van Gogh?" does not adequately indicate the direction the speech will take or what the speaker hopes to accomplish.

If you limit your thesis statement to one distinct aspect of the larger topic, you are more likely to be understood and to meet the time constraints.

Researching Your Topic

As you begin to work on your informative speech, you will find that you need to gather additional information. Your instructor will most likely require that you locate relevant materials in the library and cite those materials in your speech. In this section, we discuss the process of researching your topic and thesis.

Conducting research for a major informative speech can be a daunting task. In this section, we discuss a number of strategies and techniques that you can use to gather and organize source materials for your speech.

Gathering Materials

Gathering materials can be a daunting task. You may want to do some research before you choose a topic. Once you have a topic, you have many options for finding information. You can conduct interviews, write or call for information from a clearinghouse or public relations office, and consult books, magazines, journals, newspapers, television and radio programs, and government documents. The library will probably be your primary source of information. You can use many of the libraries databases or talk to a reference librarian to learn how to conduct efficient research.

Taking Notes

While doing your research, you may want to carry notecards. When you come across a useful passage, copy the source and the information onto the notecard or copy and paste the information. You should maintain a working bibliography as you research so you always know which sources you have consulted and so the process of writing citations into the speech and creating the bibliography will be easier. You'll need to determine what information-recording strategies work best for you. Talk to other students, instructors, and librarians to get tips on conducting efficient research. Spend time refining your system and you will soon be able to focus on the information instead of the record-keeping tasks.

Citing Sources Within Your Speech

Consult with your instructor to determine how much research/source information should be included in your speech. Realize that a source citation within your speech is defined as a reference to or quotation from material you have gathered during your research and an acknowledgement of the source. For example, within your speech you might say: "As John W. Bobbitt said in the December 22, 1993, edition of the Denver Post , 'Ouch!'" In this case, you have included a direct quotation and provided the source of the quotation. If you do not quote someone, you might say: "After the first week of the 1995 baseball season, attendance was down 13.5% from 1994. This statistic appeared in the May 7, 1995, edition of the Denver Post ." Whatever the case, whenever you use someone else's ideas, thoughts, or words, you must provide a source citation to give proper credit to the creator of the information. Failure to cite sources can be interpreted as plagiarism which is a serious offense. Upon review of the specific case, plagiarism can result in failure of the assignment, the course, or even dismissal from the University. Take care to cite your sources and give credit where it is due.

Creating Your Bibliography

As with all aspects of your speech, be sure to check with your instructor to get specific details about the assignment.

Generally, the bibliography includes only those sources you cited during the speech. Don't pad the bibliography with every source you read, saw on the shelf, or heard of from friends. When you create the bibliography, you should simply go through your complete sentence outline and list each source you cite. This is also a good way to check if you have included enough reference material within the speech. You will need to alphabetize the bibiography by authors last name and include the following information: author's name, article title, publication title, volume, date, page number(s). You may need to include additional information; you need to talk with your instructor to confirm the required bibliographical format.

Some Cautions

When doing research, use caution in choosing your sources. You need to determine which sources are more credible than others and attempt to use a wide variety of materials. The broader the scope of your research, the more impressive and believable your information. You should draw from different sources (e.g., a variety of magazines-- Time, Newsweek, US News & World Report, National Review, Mother Jones ) as well as different types of sources (i.e., use interviews, newspapers, periodicals, and books instead of just newspapers). The greater your variety, the more apparent your hard work and effort will be. Solid research skills result in increased credibility and effectiveness for the speaker.

Structuring an Informative Speech

Typically, informative speeches have three parts:

Introduction

In this section, we discuss the three parts of an informative speech, calling attention to specific elements that can enhance the effectiveness of your speech. As a speaker, you will want to create a clear structure for your speech. In this section, you will find discussions of the major parts of the informative speech.

The introduction sets the tone of the entire speech. The introduction should be brief and to-the-point as it accomplishes these several important tasks. Typically, there are six main components of an effective introduction:

Attention Getters

Thesis statement, audience adaptation, credibility statement, transition to the body.

As in any social situation, your audience makes strong assumptions about you during the first eight or ten seconds of your speech. For this reason, you need to start solidly and launch the topic clearly. Focus your efforts on completing these tasks and moving on to the real information (the body) of the speech. Typically, there are six main components of an effective introduction. These tasks do not have to be handled in this order, but this layout often yields the best results.

The attention-getter is designed to intrigue the audience members and to motivate them to listen attentively for the next several minutes. There are infinite possibilities for attention-getting devices. Some of the more common devices include using a story, a rhetorical question, or a quotation. While any of these devices can be effective, it is important for you to spend time strategizing, creating, and practicing the attention-getter.

Most importantly, an attention-getter should create curiosity in the minds of your listeners and convince them that the speech will be interesting and useful. The wording of your attention-getter should be refined and practiced. Be sure to consider the mood/tone of your speech; determine the appropriateness of humor, emotion, aggressiveness, etc. Not only should the words get the audiences attention, but your delivery should be smooth and confident to let the audience know that you are a skilled speaker who is prepared for this speech.

The crowd was wild. The music was booming. The sun was shining. The cash registers were ringing.

This story-like re-creation of the scene at a Farm Aid concert serves to engage the audience and causes them to think about the situation you are describing. Touching stories or stories that make audience members feel involved with the topic serve as good attention-getters. You should tell a story with feeling and deliver it directly to the audience instead of reading it off your notecards.

Example Text : One dark summer night in 1849, a young woman in her 20's left Bucktown, Maryland, and followed the North Star. What was her name? Harriet Tubman. She went back some 19 times to rescue her fellow slaves. And as James Blockson relates in a 1984 issue of National Geographic , by the end of her career, she had a $40,000.00 price on her head. This was quite a compliment from her enemies (Blockson 22).

Rhetorical Question

Rhetorical questions are questions designed to arouse curiosity without requiring an answer. Either the answer will be obvious, or if it isn't apparent, the question will arouse curiosity until the presentation provides the answer.

An example of a rhetorical question to gain the audiences attention for a speech about fly-fishing is, "Have you ever stood in a freezing river at 5 o'clock in the morning by choice?"

Example Text: Have you ever heard of a railroad with no tracks, with secret stations, and whose conductors were considered criminals?

A quotation from a famous person or from an expert on your topic can gain the attention of the audience. The use of a quotation immediately launches you into the speech and focuses the audience on your topic area. If it is from a well-known source, cite the author first. If the source is obscure, begin with the quote itself.

Example Text : "No day dawns for the slave, nor is it looked for. It is all night--night forever . . . ." (Pause) This quote was taken from Jermain Loguen, a fugitive who was the son of his Tennessee master and a slave woman.

Unusual Statement

Making a statement that is unusual to the ears of your listeners is another possibility for gaining their attention.

Example Text : "Follow the drinking gourd. That's what I said, friend, follow the drinking gourd." This phrase was used by slaves as a coded message to mean the Big Dipper, which revealed the North Star, and pointed toward freedom.

You might chose to use tasteful humor which relates to the topic as an effective way to attract the audience both to you and the subject at hand.

Example Text : "I'm feeling boxed in." [PAUSE] I'm not sure, but these may have been Henry "Box" Brown's very words after being placed on his head inside a box which measured 3 feet by 2 feet by 2 1\2 feet for what seemed to him like "an hour and a half." He was shipped by Adams Express to freedom in Philadelphia (Brown 60,92; Still 10).

Shocking Statistic

Another possibility to consider is the use of a factual statistic intended to grab your listener's attention. As you research the topic you've picked, keep your eyes open for statistics that will have impact.

Example Text : Today, John Elway's talents are worth millions, but in 1840 the price of a human life, a slave, was worth $1,000.00.

Example Text : Today I'd like to tell you about the Underground Railroad.

In your introduction, you need to adapt your speech to your audience. To keep audience members interested, tell them why your topic is important to them. To accomplish this task, you need to undertake audience analysis prior to creating the speech. Figure out who your audience members are, what things are important to them, what their biases may be, and what types of subjects/issues appeal to them. In the context of this class, some of your audience analysis is provided for you--most of your listeners are college students, so it is likely that they place some value on education, most of them are probably not bathing in money, and they live in Colorado. Consider these traits when you determine how to adapt to your audience.

As you research and write your speech, take note of references to issues that should be important to your audience. Include statements about aspects of your speech that you think will be of special interest to the audience in the introduction. By accomplishing this task, you give your listeners specific things with which they can identify. Audience adaptation will be included throughout the speech, but an effective introduction requires meaningful adaptation of the topic to the audience.

You need to find ways to get the members of your audience involved early in the speech. The following are some possible options to connect your speech to your audience:

Reference to the Occasion

Consider how the occasion itself might present an opportunity to heighten audience receptivity. Remind your listeners of an important date just passed or coming soon.

Example Text : This January will mark the 130th anniversary of a "giant interracial rally" organized by William Still which helped to end streetcar segregation in the city of Philadelphia (Katz i).

Reference to the Previous Speaker

Another possibility is to refer to a previous speaker to capitalize on the good will which already has been established or to build on the information presented.

Example Text : As Alice pointed out last week in her speech on the Olympic games of the ancient world, history can provide us with fascinating lessons.

The credibility statement establishes your qualifications as a speaker. You should come up with reasons why you are someone to listen to on this topic. Why do you have special knowledge or understanding of this topic? What can the audience learn from you that they couldn't learn from someone else? Credibility statements can refer to your extensive research on a topic, your life-long interest in an issue, your personal experience with a thing, or your desire to better the lives of your listeners by sifting through the topic and providing the crucial information.

Remember that Aristotle said that credibility, or ethos, consists of good sense, goodwill, and good moral character. Create the feeling that you possess these qualities by creatively stating that you are well-educated about the topic (good sense), that you want to help each member of the audience (goodwill), and that you are a decent person who can be trusted (good moral character). Once you establish your credibility, the audience is more likely to listen to you as something of an expert and to consider what you say to be the truth. It is often effective to include further references to your credibility throughout the speech by subtly referring to the traits mentioned above.

Show your listeners that you are qualified to speak by making a specific reference to a helpful resource. This is one way to demonstrate competence.

Example Text : In doing research for this topic, I came across an account written by one of these heroes that has deepened my understanding of the institution of slavery. Frederick Douglass', My Bondage and My Freedom, is the account of a man whose master's kindness made his slavery only more unbearable.

Your listeners want to believe that you have their best interests in mind. In the case of an informative speech, it is enough to assure them that this will be an interesting speech and that you, yourself, are enthusiastic about the topic.

Example Text : I hope you'll enjoy hearing about the heroism of the Underground Railroad as much as I have enjoyed preparing for this speech.

Preview the Main Points

The preview informs the audience about the speech's main points. You should preview every main body point and identify each as a separate piece of the body. The purpose of this preview is to let the audience members prepare themselves for the flow of the speech; therefore, you should word the preview clearly and concisely. Attempt to use parallel structure for each part of the preview and avoid delving into the main point; simply tell the audience what the main point will be about in general.

Use the preview to briefly establish your structure and then move on. Let the audience get a taste of how you will divide the topic and fulfill the thesis and then move on. This important tool will reinforce the information in the minds of your listeners. Here are two examples of a preview:

Simply identify the main points of the speech. Cover them in the same order that they will appear in the body of the presentation.

For example, the preview for a speech about kites organized topically might take this form: "First, I will inform you about the invention of the kite. Then, I will explain the evolution of the kite. Third, I will introduce you to the different types of kites. Finally, I will inform you about various uses for kites." Notice that this preview avoids digressions (e.g., listing the various uses for kites); you will take care of the deeper information within the body of the speech.

Example Text : I'll tell you about motivations and means of escape employed by fugitive slaves.

Chronological

For example, the preview for a speech about the Pony Express organized chronologically might take this form: "I'll talk about the Pony Express in three parts. First, its origins, second, its heyday, and third, how it came to an end." Notice that this preview avoids digressions (e.g., listing the reasons why the Pony Express came to an end); you will cover the deeper information within the body of the speech.

Example Text : I'll talk about it in three parts. First, its origins, second, its heyday, and third, how it came to an end.

After you accomplish the first five components of the introduction, you should make a clean transition to the body of the speech. Use this transition to signal a change and prepare the audience to begin processing specific topical information. You should round out the introduction, reinforce the excitement and interest that you created in the audience during the introduction, and slide into the first main body point.

Strategic organization helps increase the clarity and effectiveness of your speech. Four key issues are discussed in this section:

Organizational Patterns

Connective devices, references to outside research.

The body contains the bulk of information in your speech and needs to be clearly organized. Without clear organization, the audience will probably forget your information, main points, perhaps even your thesis. Some simple strategies will help you create a clear, memorable speech. Below are the four key issues used in organizing a speech.

Once you settle on a topic, you should decide which aspects of that topic are of greatest importance for your speech. These aspects become your main points. While there is no rule about how many main points should appear in the body of the speech, most students go with three main points. You must have at least two main points; aside from that rule, you should select your main points based on the importance of the information and the time limitations. Be sure to include whatever information is necessary for the audience to understand your topic. Also, be sure to synthesize the information so it fits into the assigned time frame. As you choose your main points, try to give each point equal attention within the speech. If you pick three main points, each point should take up roughly one-third of the body section of your speech.

There are four basic patterns of organization for an informative speech.

• Chronological order
• Spatial order
• Causal order
• Topical order

There are four basic patterns of organization for an informative speech. You can choose any of these patterns based on which pattern serves the needs of your speech.

Chronological Order

A speech organized chronologically has main points oriented toward time. For example, a speech about the Farm Aid benefit concert could have main points organized chronologically. The first main point focuses on the creation of the event; the second main point focuses on the planning stages; the third point focuses on the actual performance/concert; and the fourth point focuses on donations and assistance that resulted from the entire process. In this format, you discuss main points in an order that could be followed on a calendar or a clock.

Spatial Order

A speech organized spatially has main points oriented toward space or a directional pattern. The Farm Aid speech's body could be organized in spatial order. The first main point discusses the New York branch of the organization; the second main point discusses the Midwest branch; the third main point discusses the California branch of Farm Aid. In this format, you discuss main points in an order that could be traced on a map.

Causal Order

A speech organized causally has main points oriented toward cause and effect. The main points of a Farm Aid speech organized causally could look like this: the first main point informs about problems on farms and the need for monetary assistance; the second main point discusses the creation and implementation of the Farm Aid program. In this format, you discuss main points in an order that alerts the audience to a problem or circumstance and then tells the audience what action resulted from the original circumstance.

Topical Order

A speech organized topically has main points organized more randomly by sub-topics. The Farm Aid speech could be organized topically: the first main point discusses Farm Aid administrators; the second main point discusses performers; the third main point discusses sponsors; the fourth main point discusses audiences. In this format, you discuss main points in a more random order that labels specific aspects of the topic and addresses them in separate categories. Most speeches that are not organized chronologically, spatially, or causally are organized topically.

Within the body of your speech, you need clear internal structure. Connectives are devices used to create a clear flow between ideas and points within the body of your speech--they serve to tie the speech together. There are four main types of connective devices:

Transitions

Internal previews, internal summaries.

Within the body of your speech, you need clear internal structure. Think of connectives as hooks and ladders for the audience to use when moving from point-to-point within the body of your speech. These devices help re-focus the minds of audience members and remind them of which main point your information is supporting. The four main types of connective devices are:

Transitions are brief statements that tell the audience to shift gears between ideas. Transitions serve as the glue that holds the speech together and allow the audience to predict where the next portion of the speech will go. For example, once you have previewed your main points and you want to move from the introduction to the body of the Farm Aid speech, you might say: "To gain an adequate understanding of the intricacies of this philanthropic group, we need to look at some specific information about Farm Aid. We'll begin by looking at the administrative branch of this massive fund-raising organization."

Internal previews are used to preview the parts of a main point. Internal previews are more focused than, but serve the same purpose as, the preview you will use in the introduction of the speech. For example, you might create an internal preview for the complex main point dealing with Farm Aid performers: "In examining the Farm Aid performers, we must acknowledge the presence of entertainers from different genres of music--country and western, rhythm and blues, rock, and pop." The internal preview provides specific information for the audience if a main point is complex or potentially confusing.

Internal summaries are the reverse of internal previews. Internal summaries restate specific parts of a main point. To internally summarize the main point dealing with Farm Aid performers, you might say: "You now know what types of people perform at the Farm Aid benefit concerts. The entertainers come from a wide range of musical genres--country and western, rhythm and blues, rock, and pop." When using both internal previews and internal summaries, be sure to stylize the language in each so you do not become redundant.

Signposts are brief statements that remind the audience where you are within the speech. If you have a long point, you may want to remind the audience of what main point you are on: "Continuing my discussion of Farm Aid performers . . . "

When organizing the body of your speech, you will integrate several references to your research. The purpose of the informative speech is to allow you and the audience to learn something new about a topic. Additionally, source citations add credibility to your ideas. If you know a lot about rock climbing and you cite several sources who confirm your knowledge, the audience is likely to see you as a credible speaker who provides ample support for ideas.

Without these references, your speech is more like a story or a chance for you to say a few things you know. To complete this assignment satisfactorily, you must use source citations. Consult your textbook and instructor for specific information on how much supporting material you should use and about the appropriate style for source citations.

While the conclusion should be brief and tight, it has a few specific tasks to accomplish:

Re-assert/Reinforce the Thesis

Review the main points, close effectively.

Take a deep breath! If you made it to the conclusion, you are on the brink of finishing. Below are the tasks you should complete in your conclusion:

When making the transition to the conclusion, attempt to make clear distinctions (verbally and nonverbally) that you are now wrapping up the information and providing final comments about the topic. Refer back to the thesis from the introduction with wording that calls the original thesis into memory. Assert that you have accomplished the goals of your thesis statement and create the feeling that audience members who actively considered your information are now equipped with an understanding of your topic. Reinforce whatever mood/tone you chose for the speech and attempt to create a big picture of the speech.

Within the conclusion, re-state the main points of the speech. Since you have used parallel wording for your main points in the introduction and body, don't break that consistency in the conclusion. Frame the review so the audience will be reminded of the preview and the developed discussion of each main point. After the review, you may want to create a statement about why those main points fulfilled the goals of the speech.

Finish strongly. When you close your speech, craft statements that reinforce the message and leave the audience with a clear feeling about what was accomplished with your speech. You might finalize the adaptation by discussing the benefits of listening to the speech and explaining what you think audience members can do with the information.

Remember to maintain an informative tone for this speech. You should not persuade about beliefs or positions; rather, you should persuade the audience that the speech was worthwhile and useful. For greatest effect, create a closing line or paragraph that is artistic and effective. Much like the attention-getter, the closing line needs to be refined and practiced. Your close should stick with the audience and leave them interested in your topic. Take time to work on writing the close well and attempt to memorize it so you can directly address the audience and leave them thinking of you as a well-prepared, confident speaker.

Outlining an Informative Speech

Two types of outlines can help you prepare to deliver your speech. The complete sentence outline provides a useful means of checking the organization and content of your speech. The speaking outline is an essential aid for delivering your speech. In this section, we discuss both types of outlines.

Two types of outlines can help you prepare to deliver your speech. The complete sentence outline provides a useful means of checking the organization and content of your speech. The speaking outline is an essential aid for delivering your speech.

The Complete Sentence Outline

A complete sentence outline may not be required for your presentation. The following information is useful, however, in helping you prepare your speech.

The complete sentence outline helps you organize your material and thoughts and it serves as an excellent copy for editing the speech. The complete sentence outline is just what it sounds like: an outline format including every complete sentence (not fragments or keywords) that will be delivered during your speech.

Writing the Outline

You should create headings for the introduction, body, and conclusion and clearly signal shifts between these main speech parts on the outline. Use standard outline format. For instance, you can use Roman numerals, letters, and numbers to label the parts of the outline. Organize the information so the major headings contain general information and the sub-headings become more specific as they descend. Think of the outline as a funnel: you should make broad, general claims at the top of each part of the outline and then tighten the information until you have exhausted the point. Do this with each section of the outline. Be sure to consult with your instructor about specific aspects of the outline and refer to your course book for further information and examples.

Using the Outline

If you use this outline as it is designed to be used, you will benefit from it. You should start the outline well before your speech day and give yourself plenty of time to revise it. Attempt to have the final, clean copies ready two or three days ahead of time, so you can spend a day or two before your speech working on delivery. Prepare the outline as if it were a final term paper.

The Speaking Outline

Depending upon the assignment and the instructor, you may use a speaking outline during your presentation. The following information will be helpful in preparing your speech through the use of a speaking outline.

This outline should be on notecards and should be a bare bones outline taken from the complete sentence outline. Think of the speaking outline as train tracks to guide you through the speech.

Many speakers find it helpful to highlight certain words/passages or to use different colors for different parts of the speech. You will probably want to write out long or cumbersome quotations along with your source citation. Many times, the hardest passages to learn are those you did not write but were spoken by someone else. Avoid the temptation to over-do the speaking outline; many speakers write too much on the cards and their grades suffer because they read from the cards.

The best strategy for becoming comfortable with a speaking outline is preparation. You should prepare well ahead of time and spend time working with the notecards and memorizing key sections of your speech (the introduction and conclusion, in particular). Try to become comfortable with the extemporaneous style of speaking. You should be able to look at a few keywords on your outline and deliver eloquent sentences because you are so familiar with your material. You should spend approximately 80% of your speech making eye-contact with your audience.

Delivering an Informative Speech

For many speakers, delivery is the most intimidating aspect of public speaking. Although there is no known cure for nervousness, you can make yourself much more comfortable by following a few basic delivery guidelines. In this section, we discuss those guidelines.

The Five-Step Method for Improving Delivery

• Read aloud your full-sentence outline. Listen to what you are saying and adjust your language to achieve a good, clear, simple sentence structure.
• Practice the speech repeatedly from the speaking outline. Become comfortable with your keywords to the point that what you say takes the form of an easy, natural conversation.
• Practice the speech aloud...rehearse it until you are confident you have mastered the ideas you want to present. Do not be concerned about "getting it just right." Once you know the content, you will find the way that is most comfortable for you.
• Practice in front of a mirror, tape record your practice, and/or present your speech to a friend. You are looking for feedback on rate of delivery, volume, pitch, non-verbal cues (gestures, card-usage, etc.), and eye-contact.
• Do a dress rehearsal of the speech under conditions as close as possible to those of the actual speech. Practice the speech a day or two before in a classroom. Be sure to incorporate as many elements as possible in the dress rehearsal...especially visual aids.

It should be clear that coping with anxiety over delivering a speech requires significant advanced preparation. The speech needs to be completed several days beforehand so that you can effectively employ this five-step plan.

Techniques for Informing

Most informative speeches rely on one of the following techniques for conveying informatio n— definition , explanation , description , demonstration , or narrative . Although some topics may lend themselves to one or another of these techniques, you usually will use a blend of techniques in your informative presentation.

13.3 Types of Presentations to Inform

Speaking to inform may fall into one of several categories. The presentation to inform may be

• an explanation,
• a description,
• or a demonstration of how to do something.

In the sections below each of these types of informative speech will be described.

Explanation

Have you ever listened to a lecture or speech where you just didn’t get it? It wasn’t that you weren’t interested, at least not at first. Perhaps the presenter used language you didn’t understand or gave a confusing example. Soon you probably lost interest and sat there, attending the speech in body but certainly not in mind. An effective speech to inform will take a complex topic or issue and explain it to the audience in ways that increase audience understanding.

No one likes to feel left out. As the speaker, it’s your responsibility to ensure that this doesn’t happen. Also know that to teach someone something new—perhaps a skill that they did not posses or a perspective that allows them to see new connections—is a real gift, both to you and the audience members. You will feel rewarded because you made a difference and they will perceive the gain in their own understanding.

As a business communicator, you may be called upon to give an informative report where you communicate status, trends, or relationships that pertain to a specific topic. The informative report is a speech where you organize your information around key events, discoveries, or technical data and provide context and illustration for your audience. They may naturally wonder, “Why are sales up (or down)?” or “What is the product leader in your lineup?” and you need to anticipate their perspective and present the key information that relates to your topic.

Description

Have you ever listened to a friend tell you about their recent trip somewhere and found the details fascinating, making you want to travel there or visit a similar place? Describing information requires emphasis on language that is vivid, captures attention, and excites the imagination. Your audience will be drawn to your effective use of color, descriptive language, and visual aids. An informative speech that focuses description will be visual in many ways. Use your imagination to place yourself in their perspective: how would you like to have someone describe the topic to you?

Demonstration

You want to teach the audience how to program the applications on a new smartphone. A demonstrative speech focuses on clearly showing a process and telling the audience important details about each step so that they can imitate, repeat, or do the action themselves. Consider the visual aids or supplies you will need.

By considering each step and focusing on how to simplify it, you can understand how the audience might grasp the new information and how you can best help them. Also, consider the desired outcome; for example, will your listeners be able to actually do the task themselves? Regardless of the sequence or pattern you will illustrate or demonstrate, consider how people from your anticipated audience will respond, and budget additional time for repetition and clarification.

Chefs inform through demonstration. Although they make it seem easy, it is complex and difficult.

Informative presentations come in all sizes, shapes, and forms. The main goal in an informative presentation is to inform, not to persuade, and that requires an emphasis on credibility, for the speaker and the data or information presented.

Here are additional, more specific types of informative presentations:

• Biographical information
• Case study results
• Comparative advantage results
• Cost-benefit analysis results
• Feasibility studies
• Field study results
• Financial trends analysis
• Health, safety, and accident rates
• Instruction guidelines
• Laboratory results
• Product or service orientations
• Progress reports
• Research results
• Technical specifications

Depending on the situation, the audience, and the specific information to be presented, any of these types of presentation may be given as an explanation, a report, a description, or a demonstration.

In summary, an informative speech may explain, report, describe, or demonstrate how to do something.

9 Types of Presentations You Should Know (With Examples)

8 Effective Ways to Introduce Yourself in a Presentation

How to write a problem statement slide, how to write the perfect titles for your slides, pro tips to create an impactful employee induction presentation.

Mastering the art of crafting and delivering presentations is vital across diverse contexts and industries. In a world where effective communication often determines success or failure, understanding the various types of presentations is key. Each presentation type fulfills a distinct role, which we will understand in this article. So, let’s get going!

Why is it Important to Understand Different Types of Presentations?

Different presentations serve distinct purposes, each tailored to achieve specific goals and connect with audiences uniquely.  Imagine trying to motivate a team using the same approach you would use to deliver a technical report – it just would not work. 

Whether aiming to inform, persuade, train, or inspire, understanding and utilizing various presentation styles ensures you communicate your message properly and engage your audience on the right level. Each presentation type, from informative to persuasive, is like a tool in a toolkit designed for specific tasks to help you achieve your objectives.

Moreover, adapting to different styles keeps your communication fresh and dynamic. A one-size-fits-all approach can lead to disengagement, whereas using the right style for the proper context maintains interest and maximizes impact. 

Types of Presentations

1. informative presentation.

Informative presentations are designed to educate the audience on a specific topic. They provide clear, factual, and comprehensive information that enhances understanding. These presentations are commonly used in academic settings, corporate training sessions, and public awareness campaigns. 

For instance, a professor might deliver an informative presentation on the impacts of global warming, outlining the scientific principles, current data, and potential future scenarios. 

To make such presentations more effective, focus on organization and clarity. Commence with an introduction that sets the context and outlines the main points you will cover. Break down each section to address a specific aspect of the topic, providing detailed explanations supported by evidence and examples. Make sure to harness the power of visuals and charts to explain complicated data in simple terms.

2. Persuasive Presentation

Persuasive presentations convince the audience to adopt a particular viewpoint or take specific actions. These presentations are essential in various contexts, such as marketing, sales, and advocacy. 

The best way to increase their impact is by proactively addressing potential objections and counter-arguments. This approach demonstrates thorough understanding and preparation, which strengthens your credibility. 

Incorporate testimonials, case studies, and real-life examples to enhance persuasion by providing tangible proof of your claims. Deliver a clear and compelling call to action at the end of the presentation to encourage the audience to take the desired step, whether supporting a cause or changing a behavior. 

For example, this style can be used by non-profit leaders to advocate for a cause, such as raising funds for calamities, creating awareness, etc.

3. Demonstrative Presentation

How-to-do or demonstrative presentations focus on showing the audience how to do something through detailed, step-by-step instructions. They are particularly effective in educational settings, workshops, and training sessions where practical knowledge and hands-on experience are essential. 

For example, a project manager conducting a training session might give a demonstrative presentation on using a new project management software. The manager would guide the team through each stage of the software, from setting up a new project to tracking progress and generating reports, ensuring that participants understand and can replicate the steps independently.

Interactive elements, such as allowing the audience to follow along or ask questions in real-time, can further enhance understanding and retention. 

4. Sales Presentation

Have you ever found it challenging to convince customers to buy a product or service? Here sales presentations can help you navigate the challenge. These presentations showcase your unique value propositions, address the pains of your audience, and convey how your products can improve their situation.

For example, a sales representative for a new software solution might present its advanced features, user-friendly interface, and how it can streamline the client’s workflow, ultimately saving time and increasing productivity.

To make a sales presentation effective, you must understand the audience’s needs and tailor your content accordingly. Highlight the product’s core competencies, such as its superior performance, cost-effectiveness, or innovative features. Close your presentation and encourage the audience to take the next step, whether scheduling a follow-up meeting, requesting a demo, or making a purchase. 

5. Motivational Presentation

A motivational presentation aims to inspire and energize the audience, encouraging them to achieve their goals or make positive life changes. Such presentations often appeal to emotions, using powerful stories, personal experiences, and uplifting messages to connect with the audience on a deeper level. 

For instance, a keynote speaker at a corporate event might share their journey from overcoming significant challenges to achieving success, emphasizing resilience and perseverance as keys to personal and professional growth.

You can curate an engaging narrative that resonates deeply with the audience’s aspirations and struggles and engage them with relatable anecdotes and success stories that forge an emotional connection. Use inspirational quotes, vivid imagery, and energetic delivery to boost the motivational effect, encouraging listeners to visualize their own success and fully believe in their potential.

Offer practical advice, set achievable challenges, or provide valuable resources to support their journey. By leaving the audience with a strong sense of empowerment and clear direction, you can drive meaningful change and ignite a proactive mindset that propels them toward success.

6. Status or Progress Presentation

A status or progress presentation provides an update on the current state of a project, initiative, or objective. This type of presentation is essential for keeping stakeholders informed about progress, identifying issues, and aligning team efforts with overall goals. 

For instance, a project manager might deliver a status presentation to the executive team, highlighting key milestones achieved, current challenges, and any adjustments needed to stay on track. The presentation typically includes an overview of completed tasks, upcoming deadlines, and a review of budget and resources.

To make a status presentation impactful, focus on clarity and transparency. Organize the content to cover major areas such as progress made, key metrics, and any deviations from the original plan. Further, highlight both successes and setbacks to build trust and ensure that stakeholders have a clear understanding of where things stand.

7. Pitch Presentation

Pitch presentation is a critical tool for making a compelling case, whether an entrepreneur seeking venture capital, a startup aiming to attract customers, or a non-profit organization looking for funding.

In a highly competitive environment, a well-crafted pitch can differentiate you from others by clearly articulating what makes your offering unique and how it addresses a specific need or problem. 

By highlighting key aspects such as market demand, competitive advantages, and potential returns, a pitch presentation can capture the interest of investors, customers, or supporters, making it easier to secure the necessary support or resources. 

Pitch presentations are a critical opportunity to make a solid first impression and establish credibility. They provide a platform to showcase your expertise, vision, and commitment, which can build trust and confidence among your audience. A compelling pitch persuades stakeholders to take action and lays the foundation for future relationships and opportunities. 

8. Instructive Presentations

Instructive presentations are designed to instruct, educate, and inform an audience about a particular topic or skill. They are often used in academic settings, corporate sessions, workshops, and seminars. 

They incorporate examples, case studies, and practical applications to present key points and make the content more relatable and engaging. One key element of an instructive presentation is clarity. Presenters must ensure that their explanations are straightforward and avoid jargon unless the audience is already familiar with the topic. 

For example, a digital marketing expert can deliver an instructional presentation for small business owners who are new to online marketing.

9. Decision-Making Presentation

A decision-making presentation is designed to assist an audience in evaluating various options and making informed choices based on the information presented. 

These presentations are commonly used in business meetings, strategic planning sessions, and project evaluations. The goal is to present data, analyses, and recommendations in a way that highlights the pros and cons of different alternatives, ultimately guiding the audience toward a well-considered decision. 

Effective decision-making presentations often include visual aids such as comparison charts, decision matrices, and risk assessments. By providing a structured approach and clear criteria for evaluation, these presentations help the audience weigh their options methodically.

A Detailed Guide to Help You Choose the Right Presentation Type

Choosing the right presentation type is crucial for effectively communicating your message. The kind of presentation you select can significantly impact your audience’s engagement, understanding, and retention of the information. 

Here are some key tips to consider when deciding on the most suitable presentation type for your needs.

(i). Communication Objectives

Before selecting a presentation type, it is essential to define your goals clearly. Do you wish to inform, persuade, or motivate your audience? Understanding your key goals will guide the structure and style of your presentation. 

For instance, informative presentations are ideal for delivering factual information or educating an audience about a particular topic. These presentations should be clear, concise, and well-organized. On the other hand, if you wish to motivate your viewers, inspirational presentations are the way to go.

(ii). Audience Diversity

Knowing your audience’s demographics, background, and preferences is essential for choosing the right presentation type. Consider factors such as age, gender, education level, and cultural background to tailor your presentation style. Additionally, assess the audience’s familiarity with the topic. 

For example, for a knowledgeable audience, you can delve into more complex details, while for a general audience, it is better to keep the information accessible and straightforward. Understanding your audience’s interests and preferences can also help you choose a presentation type that will keep them engaged.

(iii). Context and Setting

The context and setting of your presentation can significantly influence your choice of presentation type. Evaluate the environment where your presentation will take place. Is it in a large auditorium, a small conference room, or online? Each setting has different requirements for presentation types and delivery methods. 

Also, consider the formality of the event. Formal settings may require a more structured and professional approach, while informal settings allow for a relaxed and conversational style. The audience size is another critical factor; larger audiences may need more structured and visually engaging presentations, while smaller groups can allow for more interaction and discussion.

(iv). Content Complexity

The complexity of your content should guide the presentation type you choose. For straightforward information, use clear and concise slides, infographics, or bullet points to avoid overwhelming the audience with too much information at once. 

Consider using detailed visuals, charts, diagrams, and multimedia elements for more intricate topics. Breaking the content into manageable sections and providing summaries can help reinforce key points and ensure the audience comprehends complex information.

For example, for detailed topics like financial performance, you can opt for informative presentations, while for simple subjects such as project progress, a status presentation would be more appropriate.

(v). Personal Style

Your personal presentation style plays a significant role in the effectiveness of your delivery. Choose a presentation type that aligns with your strengths and comfort level. If you are confident in storytelling, consider a narrative-driven presentation, whereas if you are more comfortable with data, focus on data-driven presentations. 

Utilize your preferred methods for engaging the audience, whether it’s through humor, interactive elements, or compelling visuals. Leveraging your strengths can enhance your presentation’s impact and make it more engaging for your audience.

Suppose your strength lies in convincing and negotiating with people. Here, you can leverage your skills to deliver a compelling persuasive presentation and convince the audience to take a desired action.

(vi). Time Constraints

The time available for your presentation will affect how much content you can cover and the depth of detail you can provide. For brief time slots, focus on key points and ensure clarity and conciseness, using impactful visuals and avoiding overloading the audience with information. 

With more extended presentations, you can delve deeper into the topic, include interactive elements, and engage in discussions with the audience. Plan for breaks and ensure a logical flow of information to keep the audience intrigued throughout.

Tips to Ace All Types of Presentations

1. use visuals.

Use professional PowerPoint templates to create presentations and give your slides a professional look. You can add visuals such as charts, graphs, images, and even videos to make your presentation look stunning. Ensure that your visual resonates with the topic and does not distract the audience from the main theme of the presentation.

2. Structure It Correctly

The structure of your presentation is crucial as it acts as an anchor for the audience. Start by introducing your topic, followed by details such as pros and cons, metrics, data, etc., and then summarize with a strong conclusion.

3. Incorporate Stories

Stories wire human beings into listening and have a great impact on engagement as well. By using stories in your presentation, you can communicate your message in a much better manner and make it more impactful.

4. Make It Interactive

Encourage interaction through questions, discussions, or activities. Engaging with your audience keeps them interested and makes your presentation more dynamic.

5. Deliver it Right

Consider various aspects of delivery to maximize the effectiveness of your presentation.

• Body Language and Gesture

Utilize gestures and movement to emphasize points and convey enthusiasm. Positive body language enhances your credibility and engages your audience.

• Maintain Eye Contact

Make eye contact to convey confidence and build rapport with your audience.

• Pay Attention to Pace and Tone

Speak clearly and at a moderate pace. Modify your tone to emphasize essential points and maintain audience interest. Avoid speaking too fast or monotonously.

• Be Authentic

Be yourself and let your personality shine through. Authenticity helps build credibility with your audience, making your message more relatable and memorable.

6. Wrap Your Presentation on Time

Respect your audience’s time by staying focused on your key messages. Avoid unnecessary details and keep your presentation concise and to the point. 

7. Practice

Rehearse your presentation often to refine your delivery, timing, and transitions. Practicing helps build confidence and allows you to handle unexpected issues smoothly. Anticipate potential questions and prepare concise, thoughtful responses. Handling questions confidently demonstrates your expertise and readiness. You should also be prepared for technical difficulties and have a backup plan in place. Stay calm and composed, and use any issues to demonstrate problem-solving skills.

Understanding and effectively utilizing different presentations can significantly enhance your ability to communicate and achieve your objectives. By selecting the appropriate presentation style and applying best practices, you can ensure that your communication is impactful, persuasive, and aligned with your goals.

Informative presentations.

1. Types of Informative Presentations

The main goal of an informative presentation is to inform, not to persuade, and that requires an emphasis on credibility, both for the speaker and the data or information presented. Extra attention to sources is required and you’ll need to indicate what reports, texts, or websites you used for your analyses and conclusions.

Informative presentations come in all sizes, shapes, and forms.

• Explanation
• Description
• Demonstration
• Biographical information
• Case study results
• Comparative advantage results
• Cost-benefit analysis results
• Feasibility studies
• Field study results
• Financial trends analysis
• Health, safety, and accident rates
• Instruction guidelines
• Laboratory results
• Product or service orientations
• Progress reports
• Research results
• Technical specifications

1a. Explanation

think about it Have you ever listened to a lecture or speech where you just didn’t get it? It wasn’t that you weren’t interested, at least not at first. Perhaps the professor used language and jargon, gave a confusing example, or omitted something that would have linked facts or concepts together. Soon you probably lost interest and just sat there, attending the speech or lecture in body but certainly not in mind.

An effective speech to inform will take a complex topic or issue and explain it to the audience in ways that increase audience understanding.

Consider creative ways to explain your topic (e.g., visually, using definitions and examples, providing a case study, etc.) that can lay a foundation on common ground with your audience, and then build on it.

As the speaker, it’s your responsibility to ensure that your audience members feel included. Also know that to teach someone something new - perhaps a skill that they did not posses or a perspective that allows them to see new connections - is a real gift, both to you and the audience members.

You will feel rewarded because you made a difference and they will perceive the gain in their own understanding.

As a business communicator, you may be called upon to give an informative report where you communicate status, trends, or relationships that pertain to a specific topic. You might have only a few moments to speak, and you may have to prepare within a tight timeframe. Your listeners may want "just the highlights," only to ask pointed questions that require significant depth and preparation on your part.

The informative report is a speech where you organize your information around key events, discoveries, or technical data and provide context and illustration for your audience.

IN CONTEXT Your audience members may naturally wonder, "Why are sales up (or down)?" or "What is the product leader in your lineup?" and you need to anticipate their perspective and present the key information that relates to your topic. If everyone in the room knows the product line, you may not need much information about your bestseller, but instead must place emphasis on marketing research that seems to indicate why it is the bestseller. Or perhaps you are asked to be the scout and examine a new market, developing strategies to penetrate it. You’ll need to orient your audience and provide key information about the market and demonstrate leadership as you articulate your strategies.

You have a perspective gained by time and research, and your audience wants to know why you see things the way you do, as well as learn what you learned. A status report may be short or long, and may be an update that requires little background, but always consider the audience and what common ground you are building your speech on.

1c. Description

think about it Have you ever listened to a friend tell you about their recent trip somewhere and found the details fascinating, making you want to travel there or visit a similar place? Or perhaps you listened to your chemistry teacher describe a chemical reaction you were going to perform in class, and you understood the process and could reasonably anticipate the outcome.

Describing information requires emphasis on language that is vivid, captures attention, and excites the imagination. Your audience will be drawn to your effective use of color, descriptive language, and visual aids.

An informative speech that focuses on description will thus be visual in many ways. You may choose to illustrate with images, video and audio clips, and maps. Your first-person experience combined with your content will allow the audience to come to know a topic, area, or place through you, or secondhand.

The imagination of your audience is your ally, and you should aim to stimulate it with attention-getting devices and clear visual aids. Use your imagination to place yourself in the audience's perspective: How would you like to have someone describe the topic to you?

1d. Demonstration

A demonstrative speech focuses on clearly showing a process and telling the audience members important details about each step so that they can imitate, repeat, or do the action themselves. If the topic is complicated, think of ways to simplify each step.

Consider the visual aids or supplies you will need in order to give the best presentation of the steps involved in the task.

IN CONTEXT You may have noticed that cooking shows on television rarely show the chef chopping and measuring ingredients during the demonstration. Instead, the ingredients are chopped and measured ahead of time, and the chef simply adds each item to the dish with a brief comment like, "Now we’ll stir in half a cup of chicken stock." So, if you want to present a demonstration speech on the ways to make a paper airplane, one that will turn left or right, go up and down, or perform loops, consider how best to present your topic. Perhaps illustrating the process of making one airplane, followed by an example of how to make adjustments to the plane to allow for different flight patterns, would be effective. Would you need additional paper airplanes made in advance of your speech? Would an example of the paper airplane in each of the key stages of production be helpful to have ready before the speech?

Having all your preparation done ahead of time can make a world of difference, and your audience will appreciate your thoughtful approach. By considering each step and focusing on how to simplify it, you can understand how the audience members might grasp the new information and how you can best help them do so.

Also, consider the desired outcome.

Regardless of the sequence or pattern you will illustrate or demonstrate, consider how people from your anticipated audience will respond, and budget additional time for repetition and clarification.

summary In this lesson, you learned about four different types of informative presentations . Although each is meant to increase audience understanding, there are key differences. Explanation presentations break down complex topics in a way that allows for easy comprehension. Reports are often much shorter and communicate pertinent information on a specific topic. Description presentations engage the imagination through vivid language or visuals. Finally, demonstrations teach audiences a skill or process by example. Best of luck in your learning!
