A Stanford researcher found that too much homework can negatively affect kids, especially their lives away from school, where family, friends and activities matter.

“Our findings on the effects of homework challenge the traditional assumption that homework is inherently good,” wrote Denise Pope , a senior lecturer at the Stanford Graduate School of Education and a co-author of a study published in the Journal of Experimental Education .

The researchers used survey data to examine perceptions about homework, student well-being and behavioral engagement in a sample of 4,317 students from 10 high-performing high schools in upper-middle-class California communities. Along with the survey data, Pope and her colleagues used open-ended answers to explore the students’ views on homework.

Median household income exceeded $90,000 in these communities, and 93 percent of the students went on to college, either two-year or four-year.

Students in these schools average about 3.1 hours of homework each night.

“The findings address how current homework practices in privileged, high-performing schools sustain students’ advantage in competitive climates yet hinder learning, full engagement and well-being,” Pope wrote.

Pope and her colleagues found that too much homework can diminish its effectiveness and even be counterproductive. They cite prior research indicating that homework benefits plateau at about two hours per night, and that 90 minutes to two and a half hours is optimal for high school.

Their study found that too much homework is associated with:

* Greater stress: 56 percent of the students considered homework a primary source of stress, according to the survey data. Forty-three percent viewed tests as a primary stressor, while 33 percent put the pressure to get good grades in that category. Less than 1 percent of the students said homework was not a stressor.

* Reductions in health: In their open-ended answers, many students said their homework load led to sleep deprivation and other health problems. The researchers asked students whether they experienced health issues such as headaches, exhaustion, sleep deprivation, weight loss and stomach problems.

* Less time for friends, family and extracurricular pursuits: Both the survey data and student responses indicate that spending too much time on homework meant that students were “not meeting their developmental needs or cultivating other critical life skills,” according to the researchers. Students were more likely to drop activities, not see friends or family, and not pursue hobbies they enjoy.

A balancing act

The results offer empirical evidence that many students struggle to find balance between homework, extracurricular activities and social time, the researchers said. Many students felt forced or obligated to choose homework over developing other talents or skills.

Also, there was no relationship between the time spent on homework and how much the student enjoyed it. The research quoted students as saying they often do homework they see as “pointless” or “mindless” in order to keep their grades up.

“This kind of busy work, by its very nature, discourages learning and instead promotes doing homework simply to get points,” Pope said.

She said the research calls into question the value of assigning large amounts of homework in high-performing schools. Homework should not be simply assigned as a routine practice, she said.

“Rather, any homework assigned should have a purpose and benefit, and it should be designed to cultivate learning and development,” wrote Pope.

High-performing paradox

In places where students attend high-performing schools, too much homework can reduce their time to foster skills in the area of personal responsibility, the researchers concluded. “Young people are spending more time alone,” they wrote, “which means less time for family and fewer opportunities to engage in their communities.”

Student perspectives

The researchers say that while their open-ended or “self-reporting” methodology to gauge student concerns about homework may have limitations – some might regard it as an opportunity for “typical adolescent complaining” – it was important to learn firsthand what the students believe.

The paper was co-authored by Mollie Galloway from Lewis and Clark College and Jerusha Conner from Villanova University.

School Stress Takes A Toll On Health, Teens And Parents Say

Colleen Frainey, 16, of Tualatin, Ore., cut back on advanced placement classes in her junior year because the stress was making her physically ill.

When high school junior Nora Huynh got her report card, she was devastated to see that she didn't get a perfect 4.0.

Nora "had a total meltdown, cried for hours," her mother, Jennie Huynh of Alameda, Calif., says. "I couldn't believe her reaction."

Nora is doing college-level work, her mother says, but many of her friends are taking enough advanced classes to boost their grade-point averages above 4.0. "It breaks my heart to see her upset when she's doing so awesome and going above and beyond."

And the pressure is taking a physical toll, too. At age 16, Nora is tired, is increasingly irritated with her siblings and often suffers headaches, her mother says.

Teens Talk Stress

When NPR asked on Facebook if stress is an issue for teenagers, they spoke loud and clear:

• "Academic stress has been a part of my life ever since I can remember," wrote Bretta McCall, 16, of Seattle. "This year I spend about 12 hours a day on schoolwork. I'm home right now because I was feeling so sick from stress I couldn't be at school. So as you can tell, it's a big part of my life!"
• "At the time of writing this, my weekend assignments include two papers, a PowerPoint to go with a 10-minute presentation, studying for a test and two quizzes, and an entire chapter (approximately 40 pages) of notes in a college textbook," wrote Connor West of New Jersey.
• "It's a problem that's basically brushed off by most people," wrote Kelly Farrell in Delaware. "There's this mentality of, 'You're doing well, so why are you complaining?' " She says she started experiencing symptoms of stress in middle school, and was diagnosed with panic disorder and generalized anxiety disorder in high school.
• "Parents are the worst about all of this," writes Colin Hughes of Illinois. "All I hear is, 'Work harder, you're a smart kid, I know you have it in you, and if you want to go to college you need to work harder.' It's a pain."

Parents are right to be worried about stress and their children's health, says Mary Alvord , a clinical psychologist in Maryland and public education coordinator for the American Psychological Association.

"A little stress is a good thing," Alvord says. "It can motivate students to be organized. But too much stress can backfire."

Almost 40 percent of parents say their high-schooler is experiencing a lot of stress from school, according to a new NPR poll conducted with the Robert Wood Johnson Foundation and the Harvard School of Public Health. In most cases, that stress is from academics, not social issues or bullying, the poll found. (See the full results here .)

Homework was a leading cause of stress, with 24 percent of parents saying it's an issue.

Teenagers say they're suffering, too. A survey by the American Psychological Association found that nearly half of all teens — 45 percent — said they were stressed by school pressures.

Chronic stress can cause a sense of panic and paralysis, Alvord says. The child feels stuck, which only adds to the feeling of stress.

Parents can help put the child's distress in perspective, particularly when they get into what Alvord calls catastrophic "what if" thinking: "What if I get a bad grade, then what if that means I fail the course, then I'll never get into college."

Then move beyond talking and do something about it.

Colleen pets her horse, Bishop. They had been missing out on rides together because of homework.

That's what 16-year-old Colleen Frainey of Tualatin, Ore., did. As a sophomore last year, she was taking all advanced courses. The pressure was making her sick. "I didn't feel good, and when I didn't feel good I felt like I couldn't do my work, which would stress me out more," she says.

Mom Abigail Frainey says, "It was more than we could handle as a family."

With encouragement from her parents, Colleen dropped one of her advanced courses. The family's decision generated disbelief from other parents. "Why would I let her take the easy way out?" Abigail Frainey heard.

But she says dialing down on academics was absolutely the right decision for her child. Colleen no longer suffers headaches or stomachaches. She's still in honors courses, but the workload this year is manageable.

Even better, Colleen now has time to do things she never would have considered last year, like going out to dinner with the family on a weeknight, or going to the barn to ride her horse, Bishop.

Psychologist Alvord says a balanced life should be the goal for all families. If a child is having trouble getting things done, parents can help plan the week, deciding what's important and what's optional. "Just basic time management — that will help reduce the stress."

Is homework a necessary evil?

After decades of debate, researchers are still sorting out the truth about homework’s pros and cons. One point they can agree on: Quality assignments matter.

• Schools and Classrooms

Homework battles have raged for decades. For as long as kids have been whining about doing their homework, parents and education reformers have complained that homework's benefits are dubious. Meanwhile many teachers argue that take-home lessons are key to helping students learn. Now, as schools are shifting to the new (and hotly debated) Common Core curriculum standards, educators, administrators and researchers are turning a fresh eye toward the question of homework's value.

But when it comes to deciphering the research literature on the subject, homework is anything but an open book.

The 10-minute rule

In many ways, homework seems like common sense. Spend more time practicing multiplication or studying Spanish vocabulary and you should get better at math or Spanish. But it may not be that simple.

Homework can indeed produce academic benefits, such as increased understanding and retention of the material, says Duke University social psychologist Harris Cooper, PhD, one of the nation's leading homework researchers. But not all students benefit. In a review of studies published from 1987 to 2003, Cooper and his colleagues found that homework was linked to better test scores in high school and, to a lesser degree, in middle school. Yet they found only faint evidence that homework provided academic benefit in elementary school ( Review of Educational Research , 2006).

Then again, test scores aren't everything. Homework proponents also cite the nonacademic advantages it might confer, such as the development of personal responsibility, good study habits and time-management skills. But as to hard evidence of those benefits, "the jury is still out," says Mollie Galloway, PhD, associate professor of educational leadership at Lewis & Clark College in Portland, Oregon. "I think there's a focus on assigning homework because [teachers] think it has these positive outcomes for study skills and habits. But we don't know for sure that's the case."

Even when homework is helpful, there can be too much of a good thing. "There is a limit to how much kids can benefit from home study," Cooper says. He agrees with an oft-cited rule of thumb that students should do no more than 10 minutes a night per grade level — from about 10 minutes in first grade up to a maximum of about two hours in high school. Both the National Education Association and National Parent Teacher Association support that limit.

Beyond that point, kids don't absorb much useful information, Cooper says. In fact, too much homework can do more harm than good. Researchers have cited drawbacks, including boredom and burnout toward academic material, less time for family and extracurricular activities, lack of sleep and increased stress.

In a recent study of Spanish students, Rubén Fernández-Alonso, PhD, and colleagues found that students who were regularly assigned math and science homework scored higher on standardized tests. But when kids reported having more than 90 to 100 minutes of homework per day, scores declined ( Journal of Educational Psychology , 2015).

"At all grade levels, doing other things after school can have positive effects," Cooper says. "To the extent that homework denies access to other leisure and community activities, it's not serving the child's best interest."

Children of all ages need down time in order to thrive, says Denise Pope, PhD, a professor of education at Stanford University and a co-founder of Challenge Success, a program that partners with secondary schools to implement policies that improve students' academic engagement and well-being.

"Little kids and big kids need unstructured time for play each day," she says. Certainly, time for physical activity is important for kids' health and well-being. But even time spent on social media can help give busy kids' brains a break, she says.

All over the map

But are teachers sticking to the 10-minute rule? Studies attempting to quantify time spent on homework are all over the map, in part because of wide variations in methodology, Pope says.

A 2014 report by the Brookings Institution examined the question of homework, comparing data from a variety of sources. That report cited findings from a 2012 survey of first-year college students in which 38.4 percent reported spending six hours or more per week on homework during their last year of high school. That was down from 49.5 percent in 1986 ( The Brown Center Report on American Education , 2014).

The Brookings report also explored survey data from the National Assessment of Educational Progress, which asked 9-, 13- and 17-year-old students how much homework they'd done the previous night. They found that between 1984 and 2012, there was a slight increase in homework for 9-year-olds, but homework amounts for 13- and 17-year-olds stayed roughly the same, or even decreased slightly.

Yet other evidence suggests that some kids might be taking home much more work than they can handle. Robert Pressman, PhD, and colleagues recently investigated the 10-minute rule among more than 1,100 students, and found that elementary-school kids were receiving up to three times as much homework as recommended. As homework load increased, so did family stress, the researchers found ( American Journal of Family Therapy , 2015).

Many high school students also seem to be exceeding the recommended amounts of homework. Pope and Galloway recently surveyed more than 4,300 students from 10 high-achieving high schools. Students reported bringing home an average of just over three hours of homework nightly ( Journal of Experiential Education , 2013).

On the positive side, students who spent more time on homework in that study did report being more behaviorally engaged in school — for instance, giving more effort and paying more attention in class, Galloway says. But they were not more invested in the homework itself. They also reported greater academic stress and less time to balance family, friends and extracurricular activities. They experienced more physical health problems as well, such as headaches, stomach troubles and sleep deprivation. "Three hours per night is too much," Galloway says.

In the high-achieving schools Pope and Galloway studied, more than 90 percent of the students go on to college. There's often intense pressure to succeed academically, from both parents and peers. On top of that, kids in these communities are often overloaded with extracurricular activities, including sports and clubs. "They're very busy," Pope says. "Some kids have up to 40 hours a week — a full-time job's worth — of extracurricular activities." And homework is yet one more commitment on top of all the others.

"Homework has perennially acted as a source of stress for students, so that piece of it is not new," Galloway says. "But especially in upper-middle-class communities, where the focus is on getting ahead, I think the pressure on students has been ratcheted up."

Yet homework can be a problem at the other end of the socioeconomic spectrum as well. Kids from wealthier homes are more likely to have resources such as computers, Internet connections, dedicated areas to do schoolwork and parents who tend to be more educated and more available to help them with tricky assignments. Kids from disadvantaged homes are more likely to work at afterschool jobs, or to be home without supervision in the evenings while their parents work multiple jobs, says Lea Theodore, PhD, a professor of school psychology at the College of William and Mary in Williamsburg, Virginia. They are less likely to have computers or a quiet place to do homework in peace.

"Homework can highlight those inequities," she says.

Quantity vs. quality

One point researchers agree on is that for all students, homework quality matters. But too many kids are feeling a lack of engagement with their take-home assignments, many experts say. In Pope and Galloway's research, only 20 percent to 30 percent of students said they felt their homework was useful or meaningful.

"Students are assigned a lot of busywork. They're naming it as a primary stressor, but they don't feel it's supporting their learning," Galloway says.

"Homework that's busywork is not good for anyone," Cooper agrees. Still, he says, different subjects call for different kinds of assignments. "Things like vocabulary and spelling are learned through practice. Other kinds of courses require more integration of material and drawing on different skills."

But critics say those skills can be developed with many fewer hours of homework each week. Why assign 50 math problems, Pope asks, when 10 would be just as constructive? One Advanced Placement biology teacher she worked with through Challenge Success experimented with cutting his homework assignments by a third, and then by half. "Test scores didn't go down," she says. "You can have a rigorous course and not have a crazy homework load."

Still, changing the culture of homework won't be easy. Teachers-to-be get little instruction in homework during their training, Pope says. And despite some vocal parents arguing that kids bring home too much homework, many others get nervous if they think their child doesn't have enough. "Teachers feel pressured to give homework because parents expect it to come home," says Galloway. "When it doesn't, there's this idea that the school might not be doing its job."

Galloway argues teachers and school administrators need to set clear goals when it comes to homework — and parents and students should be in on the discussion, too. "It should be a broader conversation within the community, asking what's the purpose of homework? Why are we giving it? Who is it serving? Who is it not serving?"

Until schools and communities agree to take a hard look at those questions, those backpacks full of take-home assignments will probably keep stirring up more feelings than facts.

If we’re serious about student well-being, we must change the systems students learn in, here are five steps high schools can take to support students' mental health., by tim klein and belle liang     oct 14, 2022.

This article is part of the collection: Making Sense of K-12 Student Mental Health.

Educators and parents started this school year with bated breath. Last year’s stress led to record levels of teacher burnout and mental health challenges for students.

Even before the pandemic, a mental health crisis among high schoolers loomed. According to a survey administered by the Centers for Disease Control and Prevention in 2019, 37 percent of high school students said they experienced persistent sadness or hopelessness and 19 percent reported suicidality. In response, more than half of all U.S. states mandated that schools have a mental health curriculum or include mental health in their standards .

As mental health professionals and co-authors of a book about the pressure and stress facing high school students, we’ve spent our entire careers supporting students’ mental health. Traditionally, mental health interventions are individualized and they focus on helping students manage and change their behaviors to cope with challenges they’re facing. But while working with schools and colleges across the globe as we conducted research for our book , we realized that most interventions don’t address systemic issues causing mental health problems in the first place.

It’s time we acknowledge that our education systems are directly contributing to the youth mental health crisis. And if we are serious about student well-being, we must change the systems they learn in.

Here are five bold steps that high schools can take to boost mental health.

Limit Homework or Make it Optional

Imagine applying for a job, and the hiring manager informs you that in addition to a full workday in the office, you’ll be assigned three more hours of work every night. Does this sound like a healthy work-life balance? Most adults would consider this expectation ridiculous and unsustainable. Yet, this is the workload most schools place on high school students.

Research shows that excessive homework leads to increased stress, physical health problems and a lack of balance in students' lives. And studies have shown that more than two hours of daily homework can be counterproductive , yet many teachers assign more.

Homework proponents argue that homework improves academic performance. Indeed, a meta-analysis of research on this issue found a correlation between homework and achievement. But correlation isn’t causation. Does homework cause achievement or do high achievers do more homework? While it’s likely that homework completion signals student engagement, which in turn leads to academic achievement, there’s little evidence to suggest that homework itself improves engagement in learning.

Another common argument is that homework helps students develop skills related to problem-solving, time-management and self-direction. But these skills can be explicitly taught during the school day rather than after school.

Limiting homework or moving to an optional homework policy not only supports student well-being, but it can also create a more equitable learning environment. According to the American Psychological Association, students from more affluent families are more likely to have access to resources such as devices, internet, dedicated work space and the support necessary to complete their work successfully—and homework can highlight those inequities .

Whether a school limits homework or makes it optional, it’s critical to remember that more important than the amount of homework assigned, is designing the type of activities that engage students in learning. When students are intrinsically motivated to do their homework, they are more engaged in the work, which in turn is associated with academic achievement.

Cap the Number of APs Students Can Take

Advanced Placement courses give students a taste of college-level work and, in theory, allow them to earn college credits early. Getting good grades on AP exams is associated with higher GPAs in high school and success in college, but the research tends to be correlational rather than causational.

In 2008, a little over 180,000 students took three or more AP exams. By 2018, that number had ballooned to almost 350,000 students .

However, this expansion has come at the expense of student well-being.

Over the years, we’ve heard many students express that they feel pressure to take as many AP classes as possible, which overloads them with work. That’s troubling because studies show that students who take AP classes and exams are twice as likely to report adverse physical and emotional health .

AP courses and exams also raise complex issues of equity. In 2019, two out of three Harvard freshmen reported taking AP Calculus in high school, according to Jeff Selingo, author of “ Who Gets In and Why: A Year Inside College Admissions ,” yet only half of all high schools in the country offer the course. And opportunity gaps exist for advanced coursework such as AP courses and dual enrollment, with inequitable distribution of funding and support impacting which students are enrolling and experiencing success. According to the Center for American Progress, “National data from the Civil Rights Data Collection show that students who are Black, Indigenous, and other non-Black people of color (BIPOC) are not enrolled in AP courses at rates comparable to their white and Asian peers and experience less success when they are—and the analysis for this report finds this to be true even when they attend schools with similar levels of AP course availability.”

Limiting the number of AP courses students take can protect mental health and create a more equitable experience for students.

Eliminate Class Rankings

In a study we conducted about mental health problems among high school girls, we found that a primary driver of stress was their perception of school as a hypercompetitive, zero-sum game where pervasive peer pressure to perform reigns supreme.

Class rankings fuel these cutthroat environments. They send a toxic message to young people: success requires doing better than your peers.

Ranking systems help highly selective colleges decide which students to admit or reject for admission. The purpose of high school is to develop students to their own full potential, rather than causing them to fixate on measuring up to others. Research shows that ranking systems undercut students’ learning and damage social relationships by turning peers into opponents.

Eliminating class rankings sends a powerful message to students that they are more than a number.

Become an Admission Test Objector

COVID-19 ushered in the era of test-optional admissions. De-centering standardized tests in the college application process is unequivocally a good thing. Standardized tests don’t predict student success in college , they only widen the achievement gap between privileged and underprivileged students and damage students' mental health .

Going “test optional” is an excellent first step, but it's not enough.

Even as more colleges have made tests optional, affluent students submit test scores at a higher rate than their lower-income peers and are admitted at higher rates , suggesting that testing still gives them an edge.

High schools must adhere to standardized test mandates, but they don’t have to endorse them. They can become test objectors by publicly proclaiming that these tests hold no inherent value. They can stop teaching to the test and educate parents on why they are doing so. Counseling departments can inform colleges that their school is a test objector so admission teams won’t penalize students.

Of course, students and families will still find ways to wield these tests as a competitive advantage. Over time, the more schools and educators unite to denounce these tests, the less power they will hold over students and families.

Big change starts with small steps.

Stand For What You Value

Critics may argue that such policies might hurt student outcomes. How will colleges evaluate school rigor if we limit AP courses and homework? How will students demonstrate their merits without class rankings and standardized test scores?

The truth is, the best school systems in the world succeed without homework, standardized test scores or an obsession with rigorous courses. And many U.S. schools have found creative and empowering ways to showcase student merit beyond rankings and test scores.

If we aren’t willing to change policies and practices that have been shown to harm students’ well-being, we have to ask ourselves: Do we really value mental health?

Thankfully, it doesn’t have to be an either/or scenario: We can design school systems that help students thrive academically and psychologically.

Associated Data

Table S2 . Means (M), standard deviations ( SD ) of afterschool EBRB s by grade level.

This study examined the relationships between energy balance‐related behaviours (EBRBs) outside school hours and obesity in Chinese primary school students. We also explored the influence of gender on those relationships.

The study sample was a cross‐sectional cohort of 5032 Chinese children who were enrolled in grades 1–6 in primary schools in five Chinese cities and whose mean ages ranged from seven years and three months to 11.9 years. The children's parents completed a survey on their child's height, weight and EBRBs outside school hours.

The response rate was 97%, and the reported rates of overweight and obesity were 13.6% and 13.8%, respectively. The obesity rates were higher in boys and lower grade children. Most EBRBs varied between boys and girls and with increased grade levels. The amount of time spent on academic‐related activities, screen viewing, outdoor activities and sleep was mostly associated with obesity on weekdays and varied by gender.

Rate of obesity was alarmingly high in the primary school Chinese children in this cohort, especially in younger children. Excessive time spent on academic‐related activities outside school hours, inadequate sleep, physical inactivity and higher levels of screen viewing were major contributors to obesity in these Chinese children.

Introduction

Childhood obesity has been rising rapidly in China, following the trends in developed countries 1 , and the increase is more dramatic in large urban regions 1 , 2 . According to the Chinese National Surveys on Students Constitution and Health, the prevalence of obesity in children aged 7–19 increased from 0.2% in 1985 to 8.1% in 2010. The Survey reported that obesity levels were highest among children aged seven to nine years, at 15.7% for boys and 8% for girls, and lowest in the 16–18 age group, at 6.8% for boys and 2.25% for girls 2 . While this increase has far exceeded those found in American and European children, the gender differences and high prevalence among the youngest children are particularly alarming and indicate a secular trend that could have serious health and economic implications for China in the near future 2 .

Energy balance‐related behaviours (EBRBs) refer to behaviours that influence energy intake and expenditure 3 , and the essence of obesity is dysregulation of EBRBs, leading to a positive energy balance. The links between obesity and EBRBs have been observed in preschool and primary school children 4 . Because activities at school are highly regulated and focused on academic pursuits, the study of EBRBs outside school hours – before and after school and during weekends and school holidays – provides additional insights for combating childhood obesity. Participation in outdoor activities, especially moderate‐to‐vigorous physical activity (MVPA) has been positively associated with lower body mass index (BMI), while increases in sedentary activities, such as sitting for lengthy periods of time, watching TV and playing computer games, have been associated with higher BMIs in children 4 , 5 . Epidemiological studies have also showed a close association between sleep deficiency and increases in childhood obesity 5 . However, it is not clear whether time spent on homework and other academic remedial activities outside school hours is associated with obesity in children.

From a young age, Chinese children are exposed to a fiery competitive system to prepare them for admission to universities 6 . Children start school in China at the age of 6 or 7, and primary school students are expected to spend at least three hours a day on academic‐related work, which includes homework assignments from their teachers and additional academic remedial and enrichment activities offered by external providers. This is in addition to a long school day that lasts eight to nine hours. These extra activities are paid tutoring programmes that enhance the children's academic achievement and aptitude. Little is known about the health effects of dedicating such a large amount of time to academic‐related studies on obesity in children of this age group 3 . An emerging body of research has related obesity with physical activity, sedentary behaviour and diet in Chinese children, similar to those conducted in developed countries 7 , 8 . However, a few studies have examined the effects of EBRBs outside school hours on obesity by age and gender in Chinese children.

This study reports the findings of a multicity parent survey on children's engagement in a broad range of EBRBs outside school hours in Chinese primary school students. The aims of this study were to examine the rate of obesity, the levels and patterns of EBRBs outside school hours and the relationships between engaging in EBRBs and obesity in a large sample of Chinese primary school students. Understanding children's activities outside school hours can facilitate a balanced development that promotes children's health and well‐being.

Study sample and data collection procedure

The study was conducted from March 1 to March 15, 2012 and included primary school students in five large metropolitan cities in five geographical regions of China: Beijing in Northern China, Guangzhou in Southern China, Hefei in Central China, Shanghai in Eastern Costal China and Xi'an in Western China. Four to five schools were selected from various areas of the city that were representative of the schools in the city. In each school, one classroom was randomly chosen from each of the six class grade levels to participate in the study. The parents of 5517 students were invited to complete a survey, and 5339 surveys were returned, providing a 97% response rate. Students who participated in sport teams or clubs were not asked not to complete the survey. The parents were informed that they could opt out of the study without any repercussions, and no financial incentive was provided for participating in the survey. The response rates were similar for all class grade levels and cities. After excluding the surveys with incomplete data on gender, age, grade, height and weight, 5032 students – 91% of the initial sample – were included in the data analysis. The study protocol was approved by the Research Review Committee of Beijing Sport University.

Parents were asked to complete a survey on their children's participation in five categories of leisure and nonleisure activities outside school hours on weekdays and at weekends, including three of the most common outdoor activities in children 9 . Parents talked to their children and estimated the number of hours that they spent on outdoor activities, homework assignments screen viewing – covering television and playing games on computers – remedial academic work to supplement and enrich their academic activities and sleep outside school hours on weekdays and at weekends. The students were not permitted to complete the surveys by themselves regardless of their ages. Parents were asked to report their child's current height and weight based on results from their most recent clinic visit or latest physical examination. Information was also requested on the students’ age, gender, grade levels, average school grades – with A being the best grade and F the lowest – for all subject areas (excluding physical education) and physical education. They were also asked about their own education levels and the monthly family income in renminbi, which is the Chinese currency. The students brought the completed surveys back to school the following day. The surveys were screened for completeness and entered into a database for quality checking by six research staff. These staff re‐entered 10% of the surveys to check for accuracy and the error rate was <0.0002%. Information on the children's attitudes towards outdoor activities, hygiene practices such as hand washing during outdoor activities and parent and peer support were also collected, but not included in this study.

Data analysis

The children's BMI, BMI Z‐score and standard deviations of BMI for age were calculated with the free AnthroPlus software from the World Health Organization (WHO) and using WHO Child Growth Standards 10 . The classification of obesity was based on the reference developed by the Working Group on Obesity in China (WGOC) 11 . We also classified obesity using the WHO age‐specific and sex‐specific BMI cut‐off points that were based on the WHO Child Growth Standards 12 . We used the BMI Z‐score as the continuous measure of obesity in this study, but performed the analyses on BMI as well. Associations between categorical variables were analysed with chi‐square ( χ 2 ) statistics, and associations between categorical and ordinal variables were analysed with Somer's d. Spearman's correlation was used to examine the relation between ordinal and continuous variables. The one‐way F‐test was used to test group differences or trends on continuous variables. Generalised estimation equations were used to estimate the independent associations between the BMI Z‐score as the response variable and EBRBs outside school hours as the explanatory variables. The city where the school data collection sites were based was included as a random term to control the clustering effect. The children's age, gender, grade levels, average school grades, average physical education grade, father's and mother's education levels and monthly family income were included as covariates. The analysis was repeated with stratification by gender to examine gender‐specific relationships between obesity and EBRBs outside school hours. To produce a parsimonious model, only significant covariates were kept in the final model. SPSS Statistics version 22 (IBM Corp., New York, NY, USA) was used in data analysis, with significance set at p = 0.05 based on a two‐sided test.

The study comprised 5032 students from six years and one month to 14.1 years, with a mean age of 9.70 and standard deviation of 1.72. Grades 1–6 normally cover students up to the age of 12, but sometimes they contain a few older students who are behind with their education for some reason. Table  1 shows the student characteristics and associations with obesity status. In general, the students in the study came from educated families, as 50.1% of the fathers and 46.2% of the mothers had attended college or higher education. More than two‐thirds of the families had a monthly income of <10 000 RMB, which was comparable to the 2012 national average family income of 13 000 RMB or 2100 US dollars per month. Students had a wide range of school grades in academic subject areas and physical education. Similar proportions of students from the five cities and across school grade levels were presented in the study sample (data not shown). Finally, higher levels of parent education and family income were associated with higher levels of obesity.

Table  2 shows the rate of overweight and obesity based on the Chinese WGOC reference in the overall student sample and by the cities included in the data collection. Boys were more likely to be overweight ( χ 2  = 115.48, df = 1, p < 0.001) and obese ( χ 2  = 80.43, df = 1, p < 0.001) than girls, and the patterns were similar across all five cities. The highest prevalence was observed in Beijing and Shanghai, two of the largest and most developed cities in China. Obesity rates based on the WHO Child Growth Standards are also presented. The rate for overweight was higher in the WHO reference than the WGOC reference, but the levels were similar for obesity. There was a significant inverse relationship for the total sample and by gender between the level of obesity and the students’ class grade level in school (p < 0.001 for trend) (Table  3 ). The inverse trend with age was particularly striking, with a difference of more than 10 percentage points between students in the first grade (19.6%) and the sixth grade (6.8%).

Unadjusted correlations between school grade level and obesity status a

Chinese primary students dedicated more time to academic‐related work outside school hours, namely homework and remedial academic work, and this reached almost three hours on weekdays and more than four hours on weekend days (Table S1). The time they spent on screen viewing and outdoor activities was rather limited on weekdays, at approximately one hour per day. On weekdays, boys spent more time on homework, screen viewing and sleep than girls. Girls spent more time on remedial academic work on both weekdays and weekend days than boys. Boys also spent more time on outdoor play on weekend days. Finally, children in higher grades spent more time on academic‐related activities and less time on nonacademic‐related activities and sleep, especially on weekdays (Table S2). Overall, there was a limited amount of discretionary time, approximately two to three hours per day, left for children to engage in other essential daily routine activities, such as travelling to and from school, eating meals, going to the toilet and washing (data not shown). A higher class grade level was significantly correlated with more time spent on homework and remedial academic work on weekdays and weekend days. Higher grades were also significantly correlated with less time spent on screen viewing and outdoor activities on weekend days and less sleep on weekdays.

In general, weekday afterschool EBRBs were associated more closely with obesity status as shown in Table  4 . Weekday homework, screen viewing and outdoor activities were positively associated with obesity status, while weekend day remedial academic work and weekday sleep were inversely associated (p < 0.05). Finally, obesity status was positively correlated with time spent on homework on weekdays, screen viewing on weekdays and weekend days and outdoor activities on weekdays. It was also inversely correlated with time spent on remedial academic work on weekend days and sleep on weekdays.

After controlling for significant covariates, the BMI Z‐score in the model that combined all the students was significantly and positively associated with hours of homework and screen viewing, inversely associated with hours of sleeping on weekdays and marginally and negatively associated with hours of outdoor activities on weekend days (Table  5 ). In the boys’ model, the BMI Z‐score was significantly and positively associated with hours spent on homework and negatively associated with hours of sleep on weekdays and was not related to EBRBs on weekend days. In the girls’ model, the BMI Z‐score was significantly and positively associated with hours of screen viewing on weekdays and was significantly and negatively associated with hours of outdoor activities on weekend days. The results were similar when we performed the analysis with BMI as the outcome variable (result not shown).

Findings from this survey study revealed that levels of overweight (13.7%) and obesity (13.6%) in primary school students living in large metropolitan cities were alarmingly high, continuing a secular trend that has emerged since the 2000s in Chinese children 2 , 13 . It is particularly worrying to see the gender disparity in obesity that emerged in this study, with the rate in boys nearly doubling and disproportional obesity at lower grade levels. Higher levels of parental education and family income were associated with higher levels of obesity in this sample of urban Chinese children, and this was consistent with studies conducted in the United States and other Western countries. The associations disappeared in the multivariate analysis, except for in the models for just girls, where the father's education remained a significant covariate. However, class grades and gender remained as significant covariates, suggesting the important role they play in understanding the obesity epidemic in Chinese students. Finally, there was evidence that time spent on academic‐related activities, screen viewing, outdoor activities and sleep was closely associated with obesity and that this varied by gender between weekdays and weekend days.

The rate of obesity in our study sample was consistent with recent studies based on the Chinese WGOC reference that used height and weight measured directly by trained research staff 2 , 13 . The prevalence of childhood obesity in China has doubled over the past 10 years according to a report published by the National Health and Family Planning Commission of the People's Republic of China in 2014 14 . It is not a surprise that the prevalence of childhood obesity has approached those observed in the United States and other developed countries in less than two decades, in the light of the alarming temporal increase in rate of obesity since the 1980s 8 , 13 . For instance, Ma et al. reported that the obesity rates were 0.10%, 0.30%, 0.23% and 0.23% in 1985–1995, 1995–2000, 2000–2005 and 2005–2010, respectively, using data from the Chinese National Survey on Students Constitution and Health 15 .

While some studies, including our study, have showed that time for academic‐related activity and screen viewing increased with age, while sleep duration decreased with age 8 , 16 , other studies have reported that older children and adolescents were more physically active and spent less on screen viewing 7 . A study of 2163 Chinese children aged nine years to 17 years from 11 cities measured daily physical activity and sedentary behaviour using accelerometry 17 . As the children got older, they had higher levels of moderate and vigorous physical activity (MVPA) and sedentary behaviour. However, levels of MVPA and sedentary behaviour were not correlated with children's obesity status in the study sample. The same was also observed in a sample of Australian girls 18 . These findings suggest that other EBRBs influenced the energy balance and obesity in children as well.

Concern has been raised about the faster increase in obesity in lower‐level primary school students (grades 1–3) than upper‐level students (grades 4–6) that have been found in studies of Chinese children 8 , 19 , and these were also found in our study. A similar trend has also been reported in other developing countries in recent years 20 . Although there is no clear explanation for this secular trend of obesity, Yang and Huffman speculated that the introduction of formula feeding, increased consumption of foods with high protein levels and added sugar, reduced access to physical activities and poor maternal prenatal diets might have contributed to the higher prevalence of obesity among younger children in developing countries 21 .

However, it is still unclear why the prevalence of obesity in boys in our study was nearly twice as high as the girls who took part. This gender disparity has also been reported by others studies of Chinese children 8 , 19 . As nutritious foods are in plentiful supply and food insecurity is not an issue in Chinese urban cities 1 , 13 , one plausible explanation is that boys consumed a more energy‐dense diet than girls and that led to a positive energy balance. However, food consumption or eating unhealthy foods has not been associated with a particular gender and cannot explain the differences in obesity in Chinese children reported in the current literature 7 . This means that we are left with the other parameter in the energy balance equation, namely the energy expenditure. Although we could not quantify which gender was more sedentary based on the reported EBRBs, there were clear differences in EBRBs between boys and girls that suggested that boys were more sedentary on weekdays. Furthermore, the stratified analyses showed differential associations of EBRBs with obesity: the boys’ obesity was influenced by more time spent on homework and less sleep on weekdays while the girls’ obesity was associated with more screen viewing on weekdays and less outdoor activity on weekend days. While the increased sedentary time and decreased sleep in boys can be explained by a displacement effect due to increase time spent on academic‐related work on weekdays, girls have been reported to prefer sedentary activities 17 , 22 .

Higher pressure for academic excellence from society, schools and parents has been linked to increased time spent on homework and lack of sleep and may contribute to the limited time spent on screen viewing by Chinese students, as suggested by cross‐cultural studies 8 . Chinese students spend more time on homework and other academic‐related work outside school hours and less time on screen viewing and sleep, compared to students of the same age from Western countries. However, less is known about the differences in physical activity and diet between Chinese and Western students. Although academic pressure has been related to childhood obesity in some developing countries 23 , it has not become the focus of studies in China. Our findings showed that academic‐related activities outside school hours displaced time for physical activity and sleep in primary school students 24 . This should serve as a warning to parents, schools, policy makers and ultimately the Chinese education system to re‐examine and modify the current practices and expectations of children in primary schools 7 . It should be noted that the amount of time spent on homework, screen viewing and sleep based on the parental reports in this study was similar to those reported in large national surveys in China 8 , 22 .

Childhood obesity prevention in China has generally focused on promoting physical activity and healthy eating 25 . Recently studies have identified that sedentary behaviours, such as watching TV and playing on computers, high level of life stress and lack of sleep were independently associated with obesity in Western children 5 , 26 . Findings from our study suggest that sedentary behaviour from an excessive amount of time spent on academic‐related work and inadequate sleep, in addition to a lack of physical activity and excessive screen viewing, may be responsible for increased obesity in Chinese children 7 . An examination of childhood obesity intervention studies in China revealed that focusing interventions on physical activity and unhealthy diets, commonly regarded as two primary contributors to the current obesity epidemic, produced marginally effective outcomes, suggesting additional factors may also play roles 25 . Therefore, all EBRBs need to be considered in order to prevent childhood obesity and interventions should specifically target the relevant EBRBs to be effective for different genders and age groups.

We found a positive association between obesity status and outdoor activity time on weekdays, but not on weekend days, in the study sample. Because of the ongoing school‐based national Sunshine Activity campaign, which has encouraged Chinese children to play outside in the sunshine since 2007, we assessed the time spent on outdoor activities rather than on MVPA in this study. However, it is not appropriate to equate the outdoor activities reported in this study with MVPA. The three most commonly reported outdoor activities in this study were as follows: (i) exercises and sport activities involving moderate and vigorous intensity, such as jumping with ropes, soccer, swimming, jogging and exercise stations; (ii) games and play activities involving light and moderate intensity, such as hide‐and‐seek and playing in the park; and (iii) outdoor leisure activities involving light intensity, such as leisurely strolls with friends and walking the dog. High‐intensity exercises and sports activities were less common in our cohort. When we examined these three reported activities in the study sample, we found that overweight and obese students engaged more frequently in light‐ and moderate‐intensity activities and less frequently in higher‐intensity exercises and sport activities than normal weight students on weekdays (data not shown). Therefore, the positive correlation between obesity and outdoor activities on weekdays could be due to the measurement method used. However, this cannot be directly examined in this study.

There were several limitations to the study. First, because this study used a cross‐sectional design, the findings relating to relationships between responses and explanatory variables should not be interpreted as causal. Future studies should examine the findings further using longitudinal study designs. Second, all of the data, including height and weight, were self‐reported and subject to bias in self‐reports and inaccurate recalls. Although parental reports of children's health information is regularly used in population‐based health studies, the use of such data tends to overestimate weight and that lead to overestimation of obesity rates in children 27 . Therefore, study findings based on parent‐reported height and weight should be interpreted with caution. Similarly, parental reports of the time that their children spend on various activities outside school hours on weekdays and weekend days are also subject to recall errors. Nonetheless, the obesity rates and how the school‐aged children in this study used their time were similar to studies based on directly measured height and weight or observational studies from the same period. Third, because the study data were not collected from a nationally representative sample and did not include children from small cities or rural regions, the findings should not be overgeneralised. Fourth, the use of the Chinese WGOC cut‐off reference for obesity tends to overestimate obesity for boys aged 6–16 and underestimate obesity for girls aged 3–18 and that may have exacerbated the gender disparity 28 . Finally, the study only focused on EBRBs outside school hours and did not collect data on diet and physical activity at school. Future studies need to examine EBRBs that occur both inside and outside school, including diet, to establish a full picture of the relationships between obesity and EBRBs in children.

The rate of obesity was high in Chinese primary school children, especially among boys and children in lower grades, and there were differential associations between obesity status and EBRBs in Chinese boys and girls outside school hours. Accordingly, obesity prevention programmes that only focus on physical activity, screen viewing and diet may not produce expected outcomes without addressing excessive time spent on academic‐related activity and inadequate sleep in Chinese children 25 . The design of interventions should also take into account the differences between EBRBs on weekdays and weekend days 17 . Finally, there is a need to conduct cross‐cultural studies of obesity and EBRBs that can help us to understand the underlying causes of the gender differences and the increased rates of obesity in younger children. These will enable us to develop culturally relevant lifestyle interventions for different population groups in China.

This study was partly funded by the Children's Center of China. The funder had no role in any part of the study.

More than two hours of homework may be counterproductive, research suggests.

A Stanford education researcher found that too much homework can negatively affect kids, especially their lives away from school, where family, friends and activities matter.   "Our findings on the effects of homework challenge the traditional assumption that homework is inherently good," wrote Denise Pope , a senior lecturer at the Stanford Graduate School of Education and a co-author of a study published in the Journal of Experimental Education .   The researchers used survey data to examine perceptions about homework, student well-being and behavioral engagement in a sample of 4,317 students from 10 high-performing high schools in upper-middle-class California communities. Along with the survey data, Pope and her colleagues used open-ended answers to explore the students' views on homework.   Median household income exceeded $90,000 in these communities, and 93 percent of the students went on to college, either two-year or four-year.   Students in these schools average about 3.1 hours of homework each night.   "The findings address how current homework practices in privileged, high-performing schools sustain students' advantage in competitive climates yet hinder learning, full engagement and well-being," Pope wrote.   Pope and her colleagues found that too much homework can diminish its effectiveness and even be counterproductive. They cite prior research indicating that homework benefits plateau at about two hours per night, and that 90 minutes to two and a half hours is optimal for high school.   Their study found that too much homework is associated with:   • Greater stress : 56 percent of the students considered homework a primary source of stress, according to the survey data. Forty-three percent viewed tests as a primary stressor, while 33 percent put the pressure to get good grades in that category. Less than 1 percent of the students said homework was not a stressor.   • Reductions in health : In their open-ended answers, many students said their homework load led to sleep deprivation and other health problems. The researchers asked students whether they experienced health issues such as headaches, exhaustion, sleep deprivation, weight loss and stomach problems.   • Less time for friends, family and extracurricular pursuits : Both the survey data and student responses indicate that spending too much time on homework meant that students were "not meeting their developmental needs or cultivating other critical life skills," according to the researchers. Students were more likely to drop activities, not see friends or family, and not pursue hobbies they enjoy.   A balancing act   The results offer empirical evidence that many students struggle to find balance between homework, extracurricular activities and social time, the researchers said. Many students felt forced or obligated to choose homework over developing other talents or skills.   Also, there was no relationship between the time spent on homework and how much the student enjoyed it. The research quoted students as saying they often do homework they see as "pointless" or "mindless" in order to keep their grades up.   "This kind of busy work, by its very nature, discourages learning and instead promotes doing homework simply to get points," said Pope, who is also a co-founder of Challenge Success , a nonprofit organization affiliated with the GSE that conducts research and works with schools and parents to improve students' educational experiences..   Pope said the research calls into question the value of assigning large amounts of homework in high-performing schools. Homework should not be simply assigned as a routine practice, she said.   "Rather, any homework assigned should have a purpose and benefit, and it should be designed to cultivate learning and development," wrote Pope.   High-performing paradox   In places where students attend high-performing schools, too much homework can reduce their time to foster skills in the area of personal responsibility, the researchers concluded. "Young people are spending more time alone," they wrote, "which means less time for family and fewer opportunities to engage in their communities."   Student perspectives   The researchers say that while their open-ended or "self-reporting" methodology to gauge student concerns about homework may have limitations – some might regard it as an opportunity for "typical adolescent complaining" – it was important to learn firsthand what the students believe.   The paper was co-authored by Mollie Galloway from Lewis and Clark College and Jerusha Conner from Villanova University.

How does homework affect students.

Posted by Kenny Gill

Homework is essential in the learning process of all students. It benefits them in managing time, being organized, and thinking beyond the classroom work. When students develop good habits towards homework, they enjoy good grades. The amount of homework given to students has risen by 51 percent. In most cases, this pushes them to order for custom essays online. A lot of homework can be overwhelming, affecting students in negative ways.

How homework affects the psyche of students Homework plays a crucial role in ensuring students succeeds both inside and outside the classroom. The numerous hours they spend in class, on school work, and away from family and friends lead to them experiencing exhaustion. Too much homework leads to students becoming disheartened by the school, and it chips away at their motivation for succeeding.

As a result, homework becomes an uphill battle, which they feel they will never win despite putting an effort. When they continue to find homework difficult, they consider other ways of working on it, such as cheating.

Getting enough time to relax, engage with friends and family members helps the students to have fun, thus, raising their spirit and their psyche on school work.  However, when homework exceeds, it affects their emotional well-being making them sad and unproductive students who would rather cheat their way through school.

As a result, they have to struggle with a lack of enough sleep, loss of weight, stomach problems, headaches, and fatigue. Poor eating habits where students rely on fast foods also occasions as they struggle to complete all their assignments. When combined with lack of physical activity, the students suffer from obesity and other health-related conditions. Also, they experience depression and anxiety. The pressure to attend all classes, finish the much homework, as well as have time to make social connections cripples them.

How can parents help with homework? Being an active parent in the life of your child goes a long way towards promoting the health and well-being of children. Participating in their process of doing homework helps you identify if your child is facing challenges, and provide the much-needed support.

The first step is identifying the problem your child has by establishing whether their homework is too much. In elementary school, students should not spend over twenty minutes on homework while in high school they should spend an average of two hours. If it exceeds these guidelines, then you know that the homework is too much and you need to talk with the teachers.

The other step is ensuring your child focuses on their work by eliminating distractions. Texting with friends, watching videos, and playing video games can distract your child. Next, help them create a homework routine by having a designated area for studying and organizing their time for each activity.

Why it is better to do homework with friends Extracurricular activities such as sports and volunteer work that students engage in are vital. The events allow them to refresh their minds, catch up, and share with friends, and sharpen their communication skills. Homework is better done with friends as it helps them get these benefits. Through working together, interacting, and sharing with friends, their stress reduces.

Working on assignments with friends relaxes the students. It ensures they have the help they need when tackling the work, making even too much homework bearable. Also, it develops their communication skills. Deterioration of communication skills is a prominent reason as to why homework is bad. Too much of it keeps one away from classmates and friends, making it difficult for one to communicate with other people.

Working on homework with friends, however, ensures one learns how to express themselves and solve issues, making one an excellent communicator.

How does a lot of homework affect students’ performance? Burnout is a negative effect of homework. After spending the entire day learning, having to spend more hours doing too much homework lead to burnout. When it occurs, students begin dragging their feet when it comes to working on assignments and in some cases, fail to complete them. Therefore, they end up getting poor grades, which affects their overall performance.

Excessive homework also overshadows active learning, which is essential in the learning process. It encourages active participation of students in analyzing and applying what they learn in class in the real world. As a result, this limits the involvement of parents in the process of learning and children collaboration with friends. Instead, it causes boredom, difficulties for the students to work alongside others, and lack of skills in solving problems.

Should students have homework? Well, this is the question many parents and students ask when they consider these adverse effects of homework. Homework is vital in the learning process of any student. However, in most cases, it has crossed the line from being a tool for learning and becomes a source of suffering for students. With such effects, a balance is necessary to help students learn, remain healthy, and be all rounded individuals in society.

When Is Homework Stressful? Its Effects on Students’ Mental Health

Are you wondering when is homework stressful? Well, homework is a vital constituent in keeping students attentive to the course covered in a class. By applying the lessons, students learned in class, they can gain a mastery of the material by reflecting on it in greater detail and applying what they learned through homework. 

However, students get advantages from homework, as it improves soft skills like organisation and time management which are important after high school. However, the additional work usually causes anxiety for both the parents and the child. As their load of homework accumulates, some students may find themselves growing more and more bored.

Students may take assistance online and ask someone to do my online homework . As there are many platforms available for the students such as Chegg, Scholarly Help, and Quizlet offering academic services that can assist students in completing their homework on time. 

Negative impact of homework

There are the following reasons why is homework stressful and leads to depression for students and affect their mental health. As they work hard on their assignments for alarmingly long periods, students’ mental health is repeatedly put at risk. Here are some serious arguments against too much homework.

No uniqueness

Homework should be intended to encourage children to express themselves more creatively. Teachers must assign kids intriguing assignments that highlight their uniqueness. similar to writing an essay on a topic they enjoy.

Moreover, the key is encouraging the child instead of criticizing him for writing a poor essay so that he can express himself more creatively.

Lack of sleep

One of the most prevalent adverse effects of schoolwork is lack of sleep. The average student only gets about 5 hours of sleep per night since they stay up late to complete their homework, even though the body needs at least 7 hours of sleep every day. Lack of sleep has an impact on both mental and physical health.

No pleasure

Students learn more effectively while they are having fun. They typically learn things more quickly when their minds are not clouded by fear. However, the fear factor that most teachers introduce into homework causes kids to turn to unethical means of completing their assignments.

Excessive homework

The lack of coordination between teachers in the existing educational system is a concern. As a result, teachers frequently end up assigning children far more work than they can handle. In such circumstances, children turn to cheat on their schoolwork by either copying their friends’ work or using online resources that assist with homework.

Anxiety level

Homework stress can increase anxiety levels and that could hurt the blood pressure norms in young people . Do you know? Around 3.5% of young people in the USA have high blood pressure. So why is homework stressful for children when homework is meant to be enjoyable and something they look forward to doing? It is simple to reject this claim by asserting that schoolwork is never enjoyable, yet with some careful consideration and preparation, homework may become pleasurable.

No time for personal matters

Students that have an excessive amount of homework miss out on personal time. They can’t get enough enjoyment. There is little time left over for hobbies, interpersonal interaction with colleagues, and other activities. 

However, many students dislike doing their assignments since they don’t have enough time. As they grow to detest it, they can stop learning. In any case, it has a significant negative impact on their mental health.

Children are no different than everyone else in need of a break. Weekends with no homework should be considered by schools so that kids have time to unwind and prepare for the coming week. Without a break, doing homework all week long might be stressful.

How do parents help kids with homework?

Encouraging children’s well-being and health begins with parents being involved in their children’s lives. By taking part in their homework routine, you can see any issues your child may be having and offer them the necessary support.

Set up a routine

Your student will develop and maintain good study habits if you have a clear and organized homework regimen. If there is still a lot of schoolwork to finish, try putting a time limit. Students must obtain regular, good sleep every single night.

Observe carefully

The student is ultimately responsible for their homework. Because of this, parents should only focus on ensuring that their children are on track with their assignments and leave it to the teacher to determine what skills the students have and have not learned in class.

Listen to your child

One of the nicest things a parent can do for their kids is to ask open-ended questions and listen to their responses. Many kids are reluctant to acknowledge they are struggling with their homework because they fear being labelled as failures or lazy if they do.

However, every parent wants their child to succeed to the best of their ability, but it’s crucial to be prepared to ease the pressure if your child starts to show signs of being overburdened with homework.

Talk to your teachers

Also, make sure to contact the teacher with any problems regarding your homework by phone or email. Additionally, it demonstrates to your student that you and their teacher are working together to further their education.

Homework with friends

If you are still thinking is homework stressful then It’s better to do homework with buddies because it gives them these advantages. Their stress is reduced by collaborating, interacting, and sharing with peers.

Additionally, students are more relaxed when they work on homework with pals. It makes even having too much homework manageable by ensuring they receive the support they require when working on the assignment. Additionally, it improves their communication abilities.

However, doing homework with friends guarantees that one learns how to communicate well and express themselves. 

Review homework plan

Create a schedule for finishing schoolwork on time with your child. Every few weeks, review the strategy and make any necessary adjustments. Gratefully, more schools are making an effort to control the quantity of homework assigned to children to lessen the stress this produces.

Bottom line

Finally, be aware that homework-related stress is fairly prevalent and is likely to occasionally affect you or your student. Sometimes all you or your kid needs to calm down and get back on track is a brief moment of comfort. So if you are a student and wondering if is homework stressful then you must go through this blog.

While homework is a crucial component of a student’s education, when kids are overwhelmed by the amount of work they have to perform, the advantages of homework can be lost and grades can suffer. Finding a balance that ensures students understand the material covered in class without becoming overburdened is therefore essential.

Studies of typical homework loads vary : In one, a Stanford researcher found that more than two hours of homework a night may be counterproductive. The research , conducted among students from 10 high-performing high schools in upper-middle-class California communities, found that too much homework resulted in stress, physical health problems and a general lack of balance.

Additionally, the  2014 Brown Center Report on American Education , found that with the exception of nine-year-olds, the amount of homework schools assign has remained relatively unchanged since 1984, meaning even those in charge of the curricula don't see a need for adding more to that workload.

But student experiences don’t always match these results. On our own Student Life in America survey, over 50% of students reported feeling stressed, 25% reported that homework was their biggest source of stress, and on average teens are spending one-third of their study time feeling stressed, anxious, or stuck.

The disparity can be explained in one of the conclusions regarding the Brown Report:

Of the three age groups, 17-year-olds have the most bifurcated distribution of the homework burden. They have the largest percentage of kids with no homework (especially when the homework shirkers are added in) and the largest percentage with more than two hours.

So what does that mean for parents who still endure the homework wars at home?

It means that sometimes kids who are on a rigorous college-prep track, probably are receiving more homework, but the statistics are melding it with the kids who are receiving no homework. And on our survey, 64% of students reported that their parents couldn’t help them with their work. This is where the real homework wars lie—not just the amount, but the ability to successfully complete assignments and feel success.

Parents want to figure out how to help their children manage their homework stress and learn the material.

Our Top 4 Tips for Ending Homework Wars

1. have a routine..

Every parenting advice article you will ever read emphasizes the importance of a routine. There’s a reason for that: it works. A routine helps put order into an often disorderly world. It removes the thinking and arguing and “when should I start?” because that decision has already been made. While routines must be flexible to accommodate soccer practice on Tuesday and volunteer work on Thursday, knowing in general when and where you, or your child, will do homework literally removes half the battle.

2. Have a battle plan.

Overwhelmed students look at a mountain of homework and think “insurmountable.” But parents can look at it with an outsider’s perspective and help them plan. Put in an extra hour Monday when you don’t have soccer. Prepare for the AP Chem test on Friday a little at a time each evening so Thursday doesn’t loom as a scary study night (consistency and repetition will also help lock the information in your brain). Start reading the book for your English report so that it’s underway. Go ahead and write a few sentences, so you don’t have a blank page staring at you. Knowing what the week will look like helps you keep calm and carry on.

3. Don’t be afraid to call in reserves.

You can’t outsource the “battle” but you can outsource the help ! We find that kids just do better having someone other than their parents help them —and sometimes even parents with the best of intentions aren’t equipped to wrestle with complicated physics problem. At The Princeton Review, we specialize in making homework time less stressful. Our tutors are available 24/7 to work one-to-one in an online classroom with a chat feature, interactive whiteboard, and the file sharing tool, where students can share their most challenging assignments.

4. Celebrate victories—and know when to surrender.

Students and parents can review completed assignments together at the end of the night -- acknowledging even small wins helps build a sense of accomplishment. If you’ve been through a particularly tough battle, you’ll also want to reach reach a cease-fire before hitting your bunk. A war ends when one person disengages. At some point, after parents have provided a listening ear, planning, and support, they have to let natural consequences take their course. And taking a step back--and removing any pressure a parent may be inadvertently creating--can be just what’s needed.

Homework: The Good and The Bad

Homework.  A single word that for many brings up memories of childhood stress. Now that you’re a parent, you may be reminded of that feeling every time your child spills their backpack across the table. You also may be questioning how much homework is too much and wondering how you can best help your child with their schoolwork.

Here, Dr. Cara Goodwin of Parenting Translator explains what the research actually says about homework. She outlines specific ways parents can support their kids to maximize the academic benefits and develop lifelong skills in time management and persistence.

In recent years, many parents and educators have raised concerns about homework. Specifically, they have questioned how much it enhances learning and if its benefits outweigh potential costs, such as stress to the family.

So, what does the research say?

Academic benefits vs risks of homework

One of the most important questions when it comes to homework is whether it actually helps kids understand the content better. So does it? Research finds that homework is associated with higher scores on academic standardized tests for middle and high school students, but not for elementary school students (1, 2).

In other words, homework seems to have little impact on learning in elementary school students. 

Additionally, a 2012 study found that while homework is related to higher standardized test scores for high schoolers, it is not related to higher grades.

Not surprisingly, homework is more likely to be associated with improved academic performance when students and teachers find the homework to be meaningful or relevant, according to several studies (1, 3, 4). Students tend to find homework to be most engaging when it involves solving real-world problems (5).  

The impact of homework may also depend on socioeconomic status. Students from higher income families show improved academic skills with more homework and gain more knowledge from homework, according to research. On the other hand, the academic performance of more disadvantaged children seems to be unaffected by homework (6, 7). This may be because homework provides additional stress for disadvantaged children. They are less likely to get help from their parents on homework and more likely to be punished by teachers for not completing it (8).

Non-academic benefits vs risks of homework

Academic outcomes are only part of the picture. It is important to look at how homework affects kids in ways other than grades and test scores.

Homework appears to have benefits beyond improving academic skills, particularly for younger students. These benefits include building responsibility, time management skills, and persistence (1, 9, 10). In addition, homework may also increase parents’ involvement in their children’s schooling (11, 12, 13, 14).

Yet, studies show that too much homework has drawbacks. It can reduce children’s opportunities for free play, which is essential for the development of language, cognitive, self-regulation, and social-emotional skills (15). It may also interfere with physical activity, and too much homework is associated with an increased risk for being overweight (16, 17). 

In addition to homework reducing opportunities for play, it also leads to increased conflicts and stress for families. For example, research finds that children with more hours of homework experience more academic stress, physical health problems, and lack of balance in their lives (18). 

Clearly, more is not better when it comes to homework.

What is the “right” amount of homework? 

Recent reports indicate that elementary school students are assigned three times the recommended amount of homework. Even kindergarten students report an average of 25 minutes of homework per day (19).

Additionally, the National Assessment of Educational Progress (NAEP) found that homework has been increasing in recent years for younger students. Specifically, 35% of 9-year-olds reported that they did not do homework the previous night in 1984 versus 22% of 9-years-old in 2012. However, homework levels have stayed relatively stable for 13- and 17-year-olds during this same time period. 

Research suggests that homework should not exceed 1.5 to 2.5 hours per night for high school students and no more than 1 hour per night for middle school students (1). Homework for elementary school students should be minimal and assigned with the aim of building self-regulation and independent work skills. A common rule , supported by both the National Education Association (NEA) and National Parent Teacher Association (PTA), is 10-minutes of homework per grade in elementary school. Any more than this and homework may no longer have a positive impact. Importantly, the NEA and the National PTA do not endorse homework for kindergarteners.

How can parents best help with homework?

Most parents feel that they are expected to be involved in their children’s homework (20). Yet, it is often unclear exactly how to be involved in a way that helps your child to successfully complete the assignment without taking over entirely. Most studies find that parental help is important but that it matters more HOW the parent is helping rather than how OFTEN the parent is helping (21).

While this can all feel very overwhelming for parents, there are some simple guidelines you can follow to ease the homework burden and best support your child’s learning.

1. Help only when needed.

Parents should focus on providing general monitoring, guidance and encouragement. Allow children to generate answers on their own and complete their homework as independently as possible . This is important because research shows that allowing children more independence in completing homework benefits their academic skills (22, 23). In addition, too much parent involvement and being controlling with homework is associated with worse academic performance (21, 24, 25). 

What does this look like?

• Be present when your child is completing homework to help them to understand the directions.
• Be available to answer simple questions and to provide praise for their effort and hard work.
• Only provide help when your child asks for it and step away whenever possible.

2. Have structure and routines.

Help your child create structure and to develop some routines. This helps children become more independent in completing their homework. Research finds that providing this type of structure and responsiveness is related to improved academic skills (25).

This structure may include:

• A regular time and place for homework that is free from distractions.
• Have all of the materials they need within arm’s reach.
• Teach and encourage kids to create a checklist for their homework tasks each day.

Parents can also help their children to find ways to stay motivated. For example, developing their own reward system or creating a homework schedule with breaks for fun activities.

3. Set specific rules around homework.

Research finds that parents setting rules around homework is related to higher academic performance (26). For example, parents may require that children finish homework before screen time or may require children to stop doing homework and go to sleep at a certain hour. 

4. Emphasize learning over outcome.

Encourage your child to persist in challenging assignments and frame difficult assignments as opportunities to grow. Research finds that this attitude is associated with student success (20). Research also indicates that more challenging homework is associated with enhanced school performance (27).

Additionally, help your child to view homework as an opportunity to learn and improve skills. Parents who view homework as a learning opportunity rather than something that they must get “right” or complete successfully to obtain a higher grade are more likely to have children with the same attitudes (28). 

5. Stay calm and positive.

Yes, we know this is easier said than done, but it does have a big impact on how kids persevere when things get hard! Research shows that mothers showing positive emotions while helping with homework may improve children’s motivation in homework (29)

6. Praise hard work and effort. 

Praise focused on effort is likely to increase motivation (30). In addition, research finds that putting more effort into homework may be associated with enhanced development of conscientiousness in children (31).

7. Communicate with your child’s teacher.

Let your child’s teacher know about any problems your child has with homework and the teachers’ learning goals. Research finds that open communication about homework is associated with improved school performance (32). 

In summary, research finds that homework provides some academic benefit for middle- and high-school students but is less beneficial for elementary school students. As a parent, how you are involved in your child’s homework really matters. By following these evidence-based tips, you can help your child to maximize the benefits of homework and make the process less painful for all involved!

As psychologists, we were passionate about evidence-based parenting even before having kids ourselves. Once we became parents, we were overwhelmed by the amount of parenting information available, some of which isn’t backed by research. This inspired the Helping Families Thrive mission: to bring parenting science to the real world.

Homework can be bad for your mental health. Should we get rid of it?

• Teachers are taking to social media apps like TikTok to take a stand against the idea
• Heavy workloads can be extra stressful for students, especially during the Covid-19 pandemic

It’s no secret that homework can be a pain. And as students grapple with an ongoing pandemic that has had a wide-range of mental health impacts, is it time schools start listening to their pleas about their workloads?

Some teachers are turning to social media to take a stand against homework.

Tiktok user @misguided.teacher says he doesn’t assign it because the “whole premise of homework is flawed.”

Do students need homework to learn?

For starters, he says he can’t grade work on “even playing fields” when students’ home environments can be vastly different.

“Even students who go home to a peaceful house, do they really want to spend their time on busy work? Because typically that’s what a lot of homework is, it’s busy work,” he says in the video that has garnered 1.6 million likes. “You only get one year to be 7, you only got one year to be 10, you only get one year to be 16, 18.”

Mental health experts agree heavy work loads have the potential do more harm than good for students, especially when taking into account the impacts of the pandemic. But they also say the answer may not be to eliminate homework altogether.

Emmy Kang, mental health counselor at Humantold, says studies have shown heavy workloads can be “detrimental” for students and cause a “big impact on their mental, physical and emotional health.”

“More than half of students say that homework is their primary source of stress, and we know what stress can do on our bodies,” she says, adding that staying up late to finish assignments also leads to disrupted sleep and exhaustion.

Cynthia Catchings, a licensed clinical social worker and therapist at Talkspace, says heavy workloads can also cause serious mental health problems in the long run, like anxiety and depression.

And for all the distress homework causes, it’s not as useful as many may think, says Dr. Nicholas Kardaras, a psychologist and CEO of Omega Recovery treatment center.

“The research shows that there’s really limited benefit of homework for elementary age students, that really the school work should be contained in the classroom,” he says.

For older students, Kang says homework benefits plateau at about two hours per night.

Should Hong Kong introduce a zero-homework policy?

“Most students, especially at these high-achieving schools, they’re doing a minimum of three hours, and it’s taking away time from their friends from their families, their extracurricular activities. And these are all very important things for a person’s mental and emotional health.”

Catchings, who taught Primary Three to Secondary 6 for 12 years, says she’s seen the positive effects of a no homework policy while working with students abroad.

“Not having homework was something that I always admired from French students (and) French schools, because that helped students really have time off and disconnect from school,” she says.

The answer may not be to eliminate homework completely, but to be more mindful of the type of work students go home with, suggests Kang, who was a secondary school teacher for 10 years.

“I don’t think (we) should scrap homework, I think we should scrap meaningless, purposeless, busy work-type homework. That’s something that needs to be scrapped entirely,” she says, encouraging teachers to be thoughtful and consider the amount of time it would take for students to complete assignments.

Does Homework Cause Stress? Exploring the Impact on Students’ Mental Health

How much homework is too much?

Homework has become a matter of concern for educators, parents, and researchers due to its potential effects on students’ stress levels. It’s no secret students often find themselves grappling with high levels of stress and anxiety throughout their academic careers, so understanding the extent to which homework affects those stress levels is important. 

By delving into the latest research and understanding the underlying factors at play, we hope to curate insights for educators, parents, and students who are wondering whether homework causing stress in their lives?

The Link Between Homework and Stress: What the Research Says

Over the years, numerous studies investigated the relationship between homework and stress levels in students. 

One study published in the Journal of Experimental Education found that students who reported spending more than two hours per night on homework experienced higher stress levels and physical health issues . Those same students reported over three hours of homework a night on average.

This study, conducted by Stanford lecturer Denise Pope, has been heavily cited throughout the years, with WebMD producing the below video on the topic– part of their special report series on teens and stress : 

Additional studies published by Sleep Health Journal found that long hours on homework on may be a risk factor for depression , suggesting that reducing workload outside of class may benefit sleep and mental fitness .

Homework’s Potential Impact on Mental Health and Well-being

Homework-induced stress on students can involve both psychological and physiological side effects. 

1. Potential Psychological Effects of Homework-Induced Stress:

• Anxiety: The pressure to perform well academically and meet homework expectations can lead to heightened levels of anxiety in students. Constant worry about completing assignments on time and achieving high grades can be overwhelming.

• Sleep Disturbances : Homework-related stress can disrupt students’ sleep patterns, leading to sleep anxiety or sleep deprivation, both of which can negatively impact cognitive function and emotional regulation.

• Reduced Motivation: Excessive homework demands could drain students’ motivation, causing them to feel fatigued and disengaged from their studies. Reduced motivation may lead to a lack of interest in learning, hindering students’ overall academic performance.

2. Potential Physiological Effects of Homework-Induced Stress:

• Impaired Immune Function: Prolonged stress could weaken the immune system, making students more susceptible to illnesses and infections.

• Disrupted Hormonal Balance : The body’s stress response triggers the release of hormones like cortisol, which, when chronically elevated due to stress, can disrupt the delicate hormonal balance and lead to various health issues.

• Gastrointestinal Disturbances: Stress has been known to affect the gastrointestinal system, leading to symptoms such as stomachaches, nausea, and other digestive problems.

• Cardiovascular Impact: The increased heart rate and elevated blood pressure associated with stress can strain the cardiovascular system, potentially increasing the risk of heart-related issues in the long run.

• Brain impact: Prolonged exposure to stress hormones may impact the brain’s functioning , affecting memory, concentration, and other cognitive abilities.

The Benefits of Homework

It’s important to note that homework also offers many benefits that contribute to students’ academic growth and development, such as: 

• Development of Time Management Skills: Completing homework within specified deadlines encourages students to manage their time efficiently. This valuable skill extends beyond academics and becomes essential in various aspects of life.

• Preparation for Future Challenges : Homework helps prepare students for future academic challenges and responsibilities. It fosters a sense of discipline and responsibility, qualities that are crucial for success in higher education and professional life.

• Enhanced Problem-Solving Abilities: Homework often presents students with challenging problems to solve. Tackling these problems independently nurtures critical thinking and problem-solving skills.

While homework can foster discipline, time management, and self-directed learning, the middle ground may be to  strike a balance that promotes both academic growth and mental well-being .

How Much Homework Should Teachers Assign?

As a general guideline, educators suggest assigning a workload that allows students to grasp concepts effectively without overwhelming them . Quality over quantity is key, ensuring that homework assignments are purposeful, relevant, and targeted towards specific objectives. 

Advice for Students: How to balance Homework and Well-being

Finding a balance between academic responsibilities and well-being is crucial for students. Here are some practical tips and techniques to help manage homework-related stress and foster a healthier approach to learning:

• Effective Time Management : Encourage students to create a structured study schedule that allocates sufficient time for homework, breaks, and other activities. Prioritizing tasks and setting realistic goals can prevent last-minute rushes and reduce the feeling of being overwhelmed.

• Break Tasks into Smaller Chunks : Large assignments can be daunting and may contribute to stress. Students should break such tasks into smaller, manageable parts. This approach not only makes the workload seem less intimidating but also provides a sense of accomplishment as each section is completed.

• Find a Distraction-Free Zone : Establish a designated study area that is free from distractions like smartphones, television, or social media. This setting will improve focus and productivity, reducing time needed to complete homework.

• Be Active : Regular exercise is known to reduce stress and enhance mood. Encourage students to incorporate physical activity into their daily routine, whether it’s going for a walk, playing a sport, or doing yoga.

• Practice Mindfulness and Relaxation Techniques : Encourage students to engage in mindfulness practices, such as deep breathing exercises or meditation, to alleviate stress and improve concentration. Taking short breaks to relax and clear the mind can enhance overall well-being and cognitive performance.

• Seek Support : Teachers, parents, and school counselors play an essential role in supporting students. Create an open and supportive environment where students feel comfortable expressing their concerns and seeking help when needed.

How social media became a storefront for fake pills as families struggle

Fentanyl overdoses have become a leading cause of death for minors in the last five years or so, even as overall drug use has dropped slightly. In a 2022 analysis of fentanyl-laced prescription pills, the DEA found that six out of 10 contained a potentially lethal dose of the drug.

And social media, where tainted, fake prescription drugs can be obtained with just a few clicks, is a big part of the problem. Experts, law enforcement and children’s advocates say companies like Snap, TikTok, Telegram and Meta, which owns Instagram, are not doing enough to keep children safe .

In 2022, two weeks after she turned 17, Coco left home just outside New York City to meet with a dealer she’d messaged through Instagram who promised to sell her Percocet, her mom, Julianna Arnold, recalled recently. She never made it home. She was found dead the next day, two blocks from the address that the guy had provided her.

Whatever the dealer gave Coco, her mother said, was not Percocet. It was a fake pill laced with fentanyl, which can be lethal in a dose as small as the tip of a pencil.

Mikayla Brown lost her son Elijah, who went by Eli, to a suspected fentanyl overdose in 2023, two weeks after his 15th birthday. His father found him unresponsive on a September morning last year. His cause of death was accidental fentanyl overdose. But he wasn’t trying to buy fentanyl, he was looking for Xanax, and, like Coco, ended up with tainted pills that killed him.

A few taps away

While data on the prevalence of drug sales on social platforms is hard to come by, the National Crime Prevention Council estimates that 80% of teen and young adult fentanyl poisoning deaths can be traced to some social media contact.

In a sweeping 2023 report on the problem, Colorado’s attorney general called the availability of fentanyl and other illicit substances online “staggering.”

“Due to their ubiquity, convenience, and lack of regulation, social media platforms have become a major venue for drug distribution,” the report said. “Where once a teen might have had to seek out a street dealer, hassle friends, or learn to navigate the dark web to access illicit drugs, young people can now locate drug dealers using their smartphones — with the relative ease of ordering food delivery or calling a ride-share service.”

Accidental overdoses in the U.S. have decreased slightly each year since 2021 according to the Centers for Disease Control and Prevention . Paul DelPonte, executive director and CEO of the National Crime Prevention Council, attributes this partly to more education and awareness about the issue. Among young people ages 0 to 19, there were 1,622 overdose deaths in 2021, then 1,590 in 2022, and 1,511 last year.

The decline, DelPonte said, is “very small.”

Companies respond

In a statement, Meta said drug dealers “are criminals who stop at nothing to sell their dangerous products. This is a challenge that spans across platforms, industries, and communities, and it requires all of us working together to address it.”

The company added that it works with law enforcement and proactively took down 2 million pieces of content, 99.7% before they were reported in the first three months of 2024 .

Meta says it blocks and filters “hundreds” of terms associated with illicit drug sales and links to recovery and substance abuse resources when possible. But drug dealers and other bad actors constantly shift their strategies, coming up with fresh ways to avoid detection.

Snap, in a statement, said it is “heartbroken by the fentanyl epidemic and are deeply committed to the fight against it.”

“We’ve invested in advanced technology to detect and remove illicit drug-related content, work extensively with law enforcement helping to bring dealers to justice, and continue to raise awareness and evolve our service to help keep our community safe. Criminals have no place on Snapchat,” said Jacqueline Beauchere, Global Head of Platform Safety at the company.

Lawsuits and regulation

While it can happen on any social media site, experts often single out Snapchat as a particularly dangerous platform, something the company vehemently disagrees with. In October 2022, a group of parents who say their children bought fentanyl from drug dealers they met through Snapchat sued the company for wrongful death and negligence, calling it a “haven for drug trafficking.”

Advocates are hoping that regulation of tech companies could help address the problem, as it might help with other dangers kids face on social media. In July, the Senate passed the Kids Online Safety Act , legislation designed to protect children from dangerous online content . It still awaits a vote in the House. Sen. Jeanne Shaheen, D-N.H., and Sen. Roger Marshall, R-Kan., meanwhile, introduced a bill that would require social media companies to report illicit fentanyl, methamphetamine and fake pill activity occurring on their platforms to law enforcement.

“We must do more at the federal level to combat the flow of fentanyl into our communities, and it starts by holding social media companies accountable for their part in facilitating illicit drug sales,” Shaheen said.
