statistics for homework

11 Surprising Homework Statistics, Facts & Data

The age-old question of whether homework is good or bad for students is unanswerable because there are so many “ it depends ” factors.

For example, it depends on the age of the child, the type of homework being assigned, and even the child’s needs.

There are also many conflicting reports on whether homework is good or bad. This is a topic that largely relies on data interpretation for the researcher to come to their conclusions.

To cut through some of the fog, below I’ve outlined some great homework statistics that can help us understand the effects of homework on children.

Homework Statistics List

1. 45% of parents think homework is too easy for their children.

A study by the Center for American Progress found that parents are almost twice as likely to believe their children’s homework is too easy than to disagree with that statement.

Here are the figures for math homework:

• 46% of parents think their child’s math homework is too easy.
• 25% of parents think their child’s math homework is not too easy.
• 29% of parents offered no opinion.

Here are the figures for language arts homework:

• 44% of parents think their child’s language arts homework is too easy.
• 28% of parents think their child’s language arts homework is not too easy.
• 28% of parents offered no opinion.

These findings are based on online surveys of 372 parents of school-aged children conducted in 2018.

2. 93% of Fourth Grade Children Worldwide are Assigned Homework

The prestigious worldwide math assessment Trends in International Maths and Science Study (TIMSS) took a survey of worldwide homework trends in 2007. Their study concluded that 93% of fourth-grade children are regularly assigned homework, while just 7% never or rarely have homework assigned.

3. 17% of Teens Regularly Miss Homework due to Lack of High-Speed Internet Access

A 2018 Pew Research poll of 743 US teens found that 17%, or almost 2 in every 5 students, regularly struggled to complete homework because they didn’t have reliable access to the internet.

This figure rose to 25% of Black American teens and 24% of teens whose families have an income of less than $30,000 per year.

4. Parents Spend 6.7 Hours Per Week on their Children’s Homework

A 2018 study of 27,500 parents around the world found that the average amount of time parents spend on homework with their child is 6.7 hours per week. Furthermore, 25% of parents spend more than 7 hours per week on their child’s homework.

American parents spend slightly below average at 6.2 hours per week, while Indian parents spend 12 hours per week and Japanese parents spend 2.6 hours per week.

5. Students in High-Performing High Schools Spend on Average 3.1 Hours per night Doing Homework

A study by Galloway, Conner & Pope (2013) conducted a sample of 4,317 students from 10 high-performing high schools in upper-middle-class California. 

Across these high-performing schools, students self-reported that they did 3.1 hours per night of homework.

Graduates from those schools also ended up going on to college 93% of the time.

6. One to Two Hours is the Optimal Duration for Homework

A 2012 peer-reviewed study in the High School Journal found that students who conducted between one and two hours achieved higher results in tests than any other group.

However, the authors were quick to highlight that this “t is an oversimplification of a much more complex problem.” I’m inclined to agree. The greater variable is likely the quality of the homework than time spent on it.

Nevertheless, one result was unequivocal: that some homework is better than none at all : “students who complete any amount of homework earn higher test scores than their peers who do not complete homework.”

7. 74% of Teens cite Homework as a Source of Stress

A study by the Better Sleep Council found that homework is a source of stress for 74% of students. Only school grades, at 75%, rated higher in the study.

That figure rises for girls, with 80% of girls citing homework as a source of stress.

Similarly, the study by Galloway, Conner & Pope (2013) found that 56% of students cite homework as a “primary stressor” in their lives.

8. US Teens Spend more than 15 Hours per Week on Homework

The same study by the Better Sleep Council also found that US teens spend over 2 hours per school night on homework, and overall this added up to over 15 hours per week.

Surprisingly, 4% of US teens say they do more than 6 hours of homework per night. That’s almost as much homework as there are hours in the school day.

The only activity that teens self-reported as doing more than homework was engaging in electronics, which included using phones, playing video games, and watching TV.

9. The 10-Minute Rule

The National Education Association (USA) endorses the concept of doing 10 minutes of homework per night per grade.

For example, if you are in 3rd grade, you should do 30 minutes of homework per night. If you are in 4th grade, you should do 40 minutes of homework per night.

However, this ‘rule’ appears not to be based in sound research. Nevertheless, it is true that homework benefits (no matter the quality of the homework) will likely wane after 2 hours (120 minutes) per night, which would be the NEA guidelines’ peak in grade 12.

10. 21.9% of Parents are Too Busy for their Children’s Homework

An online poll of nearly 300 parents found that 21.9% are too busy to review their children’s homework. On top of this, 31.6% of parents do not look at their children’s homework because their children do not want their help. For these parents, their children’s unwillingness to accept their support is a key source of frustration.

11. 46.5% of Parents find Homework too Hard

The same online poll of parents of children from grades 1 to 12 also found that many parents struggle to help their children with homework because parents find it confusing themselves. Unfortunately, the study did not ask the age of the students so more data is required here to get a full picture of the issue.

Interpreting the Data

Unfortunately, homework is one of those topics that can be interpreted by different people pursuing differing agendas. All studies of homework have a wide range of variables, such as:

• What age were the children in the study?
• What was the homework they were assigned?
• What tools were available to them?
• What were the cultural attitudes to homework and how did they impact the study?
• Is the study replicable?

The more questions we ask about the data, the more we realize that it’s hard to come to firm conclusions about the pros and cons of homework .

Furthermore, questions about the opportunity cost of homework remain. Even if homework is good for children’s test scores, is it worthwhile if the children consequently do less exercise or experience more stress?

Thus, this ends up becoming a largely qualitative exercise. If parents and teachers zoom in on an individual child’s needs, they’ll be able to more effectively understand how much homework a child needs as well as the type of homework they should be assigned.

The debate over whether homework should be banned will not be resolved with these homework statistics. But, these facts and figures can help you to pursue a position in a school debate on the topic – and with that, I hope your debate goes well and you develop some great debating skills!

Does homework really work?

by: Leslie Crawford | Updated: December 12, 2023

Print article

You know the drill. It’s 10:15 p.m., and the cardboard-and-toothpick Golden Gate Bridge is collapsing. The pages of polynomials have been abandoned. The paper on the Battle of Waterloo seems to have frozen in time with Napoleon lingering eternally over his breakfast at Le Caillou. Then come the tears and tantrums — while we parents wonder, Does the gain merit all this pain? Is this just too much homework?

However the drama unfolds night after night, year after year, most parents hold on to the hope that homework (after soccer games, dinner, flute practice, and, oh yes, that childhood pastime of yore known as playing) advances their children academically.

But what does homework really do for kids? Is the forest’s worth of book reports and math and spelling sheets the average American student completes in their 12 years of primary schooling making a difference? Or is it just busywork?

Homework haterz

Whether or not homework helps, or even hurts, depends on who you ask. If you ask my 12-year-old son, Sam, he’ll say, “Homework doesn’t help anything. It makes kids stressed-out and tired and makes them hate school more.”

Nothing more than common kid bellyaching?

Maybe, but in the fractious field of homework studies, it’s worth noting that Sam’s sentiments nicely synopsize one side of the ivory tower debate. Books like The End of Homework , The Homework Myth , and The Case Against Homework the film Race to Nowhere , and the anguished parent essay “ My Daughter’s Homework is Killing Me ” make the case that homework, by taking away precious family time and putting kids under unneeded pressure, is an ineffective way to help children become better learners and thinkers.

One Canadian couple took their homework apostasy all the way to the Supreme Court of Canada. After arguing that there was no evidence that it improved academic performance, they won a ruling that exempted their two children from all homework.

So what’s the real relationship between homework and academic achievement?

How much is too much?

To answer this question, researchers have been doing their homework on homework, conducting and examining hundreds of studies. Chris Drew Ph.D., founder and editor at The Helpful Professor recently compiled multiple statistics revealing the folly of today’s after-school busy work. Does any of the data he listed below ring true for you?

• 45 percent of parents think homework is too easy for their child, primarily because it is geared to the lowest standard under the Common Core State Standards .

• 74 percent of students say homework is a source of stress , defined as headaches, exhaustion, sleep deprivation, weight loss, and stomach problems.

• Students in high-performing high schools spend an average of 3.1 hours a night on homework , even though 1 to 2 hours is the optimal duration, according to a peer-reviewed study .

Not included in the list above is the fact many kids have to abandon activities they love — like sports and clubs — because homework deprives them of the needed time to enjoy themselves with other pursuits.

Conversely, The Helpful Professor does list a few pros of homework, noting it teaches discipline and time management, and helps parents know what’s being taught in the class.

The oft-bandied rule on homework quantity — 10 minutes a night per grade (starting from between 10 to 20 minutes in first grade) — is listed on the National Education Association’s website and the National Parent Teacher Association’s website , but few schools follow this rule.

Do you think your child is doing excessive homework? Harris Cooper Ph.D., author of a meta-study on homework , recommends talking with the teacher. “Often there is a miscommunication about the goals of homework assignments,” he says. “What appears to be problematic for kids, why they are doing an assignment, can be cleared up with a conversation.” Also, Cooper suggests taking a careful look at how your child is doing the assignments. It may seem like they’re taking two hours, but maybe your child is wandering off frequently to get a snack or getting distracted.

Less is often more

If your child is dutifully doing their work but still burning the midnight oil, it’s worth intervening to make sure your child gets enough sleep. A 2012 study of 535 high school students found that proper sleep may be far more essential to brain and body development.

For elementary school-age children, Cooper’s research at Duke University shows there is no measurable academic advantage to homework. For middle-schoolers, Cooper found there is a direct correlation between homework and achievement if assignments last between one to two hours per night. After two hours, however, achievement doesn’t improve. For high schoolers, Cooper’s research suggests that two hours per night is optimal. If teens have more than two hours of homework a night, their academic success flatlines. But less is not better. The average high school student doing homework outperformed 69 percent of the students in a class with no homework.

Many schools are starting to act on this research. A Florida superintendent abolished homework in her 42,000 student district, replacing it with 20 minutes of nightly reading. She attributed her decision to “ solid research about what works best in improving academic achievement in students .”

More family time

A 2020 survey by Crayola Experience reports 82 percent of children complain they don’t have enough quality time with their parents. Homework deserves much of the blame. “Kids should have a chance to just be kids and do things they enjoy, particularly after spending six hours a day in school,” says Alfie Kohn, author of The Homework Myth . “It’s absurd to insist that children must be engaged in constructive activities right up until their heads hit the pillow.”

By far, the best replacement for homework — for both parents and children — is bonding, relaxing time together.

Is Homework Good for Kids? Here’s What the Research Says

A s kids return to school, debate is heating up once again over how they should spend their time after they leave the classroom for the day.

The no-homework policy of a second-grade teacher in Texas went viral last week , earning praise from parents across the country who lament the heavy workload often assigned to young students. Brandy Young told parents she would not formally assign any homework this year, asking students instead to eat dinner with their families, play outside and go to bed early.

But the question of how much work children should be doing outside of school remains controversial, and plenty of parents take issue with no-homework policies, worried their kids are losing a potential academic advantage. Here’s what you need to know:

For decades, the homework standard has been a “10-minute rule,” which recommends a daily maximum of 10 minutes of homework per grade level. Second graders, for example, should do about 20 minutes of homework each night. High school seniors should complete about two hours of homework each night. The National PTA and the National Education Association both support that guideline.

But some schools have begun to give their youngest students a break. A Massachusetts elementary school has announced a no-homework pilot program for the coming school year, lengthening the school day by two hours to provide more in-class instruction. “We really want kids to go home at 4 o’clock, tired. We want their brain to be tired,” Kelly Elementary School Principal Jackie Glasheen said in an interview with a local TV station . “We want them to enjoy their families. We want them to go to soccer practice or football practice, and we want them to go to bed. And that’s it.”

A New York City public elementary school implemented a similar policy last year, eliminating traditional homework assignments in favor of family time. The change was quickly met with outrage from some parents, though it earned support from other education leaders.

New solutions and approaches to homework differ by community, and these local debates are complicated by the fact that even education experts disagree about what’s best for kids.

The research

The most comprehensive research on homework to date comes from a 2006 meta-analysis by Duke University psychology professor Harris Cooper, who found evidence of a positive correlation between homework and student achievement, meaning students who did homework performed better in school. The correlation was stronger for older students—in seventh through 12th grade—than for those in younger grades, for whom there was a weak relationship between homework and performance.

Cooper’s analysis focused on how homework impacts academic achievement—test scores, for example. His report noted that homework is also thought to improve study habits, attitudes toward school, self-discipline, inquisitiveness and independent problem solving skills. On the other hand, some studies he examined showed that homework can cause physical and emotional fatigue, fuel negative attitudes about learning and limit leisure time for children. At the end of his analysis, Cooper recommended further study of such potential effects of homework.

Despite the weak correlation between homework and performance for young children, Cooper argues that a small amount of homework is useful for all students. Second-graders should not be doing two hours of homework each night, he said, but they also shouldn’t be doing no homework.

Not all education experts agree entirely with Cooper’s assessment.

Cathy Vatterott, an education professor at the University of Missouri-St. Louis, supports the “10-minute rule” as a maximum, but she thinks there is not sufficient proof that homework is helpful for students in elementary school.

“Correlation is not causation,” she said. “Does homework cause achievement, or do high achievers do more homework?”

Vatterott, the author of Rethinking Homework: Best Practices That Support Diverse Needs , thinks there should be more emphasis on improving the quality of homework tasks, and she supports efforts to eliminate homework for younger kids.

“I have no concerns about students not starting homework until fourth grade or fifth grade,” she said, noting that while the debate over homework will undoubtedly continue, she has noticed a trend toward limiting, if not eliminating, homework in elementary school.

The issue has been debated for decades. A TIME cover in 1999 read: “Too much homework! How it’s hurting our kids, and what parents should do about it.” The accompanying story noted that the launch of Sputnik in 1957 led to a push for better math and science education in the U.S. The ensuing pressure to be competitive on a global scale, plus the increasingly demanding college admissions process, fueled the practice of assigning homework.

“The complaints are cyclical, and we’re in the part of the cycle now where the concern is for too much,” Cooper said. “You can go back to the 1970s, when you’ll find there were concerns that there was too little, when we were concerned about our global competitiveness.”

Cooper acknowledged that some students really are bringing home too much homework, and their parents are right to be concerned.

“A good way to think about homework is the way you think about medications or dietary supplements,” he said. “If you take too little, they’ll have no effect. If you take too much, they can kill you. If you take the right amount, you’ll get better.”

Stanford research shows pitfalls of homework

A Stanford researcher found that students in high-achieving communities who spend too much time on homework experience more stress, physical health problems, a lack of balance and even alienation from society. More than two hours of homework a night may be counterproductive, according to the study.

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.

Research Trends: Why Homework Should Be Balanced

Research suggests that while homework can be an effective learning tool, assigning too much can lower student performance and interfere with other important activities.

Homework: effective learning tool or waste of time?

Since the average high school student spends almost seven hours each week doing homework, it’s surprising that there’s no clear answer. Homework is generally recognized as an effective way to reinforce what students learn in class, but claims that it may cause more harm than good, especially for younger students, are common.

Here’s what the research says:

• In general, homework has substantial benefits at the high school level, with decreased benefits for middle school students and few benefits for elementary students (Cooper, 1989; Cooper et al., 2006).
• While assigning homework may have academic benefits, it can also cut into important personal and family time (Cooper et al., 2006).
• Assigning too much homework can result in poor performance (Fernández-Alonso et al., 2015).
• A student’s ability to complete homework may depend on factors that are outside their control (Cooper et al., 2006; OECD, 2014; Eren & Henderson, 2011).
• The goal shouldn’t be to eliminate homework, but to make it authentic, meaningful, and engaging (Darling-Hammond & Ifill-Lynch, 2006).

Why Homework Should Be Balanced

Homework can boost learning, but doing too much can be detrimental. The National PTA and National Education Association support the “10-minute homework rule,” which recommends 10 minutes of homework per grade level, per night (10 minutes for first grade, 20 minutes for second grade, and so on, up to two hours for 12th grade) (Cooper, 2010). A recent study found that when middle school students were assigned more than 90–100 minutes of homework per day, their math and science scores began to decline (Fernández-Alonso, Suárez-Álvarez, & Muñiz, 2015). Giving students too much homework can lead to fatigue, stress, and a loss of interest in academics—something that we all want to avoid.

Homework Pros and Cons

Homework has many benefits, ranging from higher academic performance to improved study skills and stronger school-parent connections. However, it can also result in a loss of interest in academics, fatigue, and a loss of important personal and family time.

Grade Level Makes a Difference

Although the debate about homework generally falls in the “it works” vs. “it doesn’t work” camps, research shows that grade level makes a difference. High school students generally get the biggest benefits from homework, with middle school students getting about half the benefits, and elementary school students getting few benefits (Cooper et al., 2006). Since young students are still developing study habits like concentration and self-regulation, assigning a lot of homework isn’t all that helpful.

Parents Should Be Supportive, Not Intrusive

Well-designed homework not only strengthens student learning, it also provides ways to create connections between a student’s family and school. Homework offers parents insight into what their children are learning, provides opportunities to talk with children about their learning, and helps create conversations with school communities about ways to support student learning (Walker et al., 2004).

However, parent involvement can also hurt student learning. Patall, Cooper, and Robinson (2008) found that students did worse when their parents were perceived as intrusive or controlling. Motivation plays a key role in learning, and parents can cause unintentional harm by not giving their children enough space and autonomy to do their homework.

Homework Across the Globe

OECD , the developers of the international PISA test, published a 2014 report looking at homework around the world. They found that 15-year-olds worldwide spend an average of five hours per week doing homework (the U.S. average is about six hours). Surprisingly, countries like Finland and Singapore spend less time on homework (two to three hours per week) but still have high PISA rankings. These countries, the report explains, have support systems in place that allow students to rely less on homework to succeed. If a country like the U.S. were to decrease the amount of homework assigned to high school students, test scores would likely decrease unless additional supports were added.

Homework Is About Quality, Not Quantity

Whether you’re pro- or anti-homework, keep in mind that research gives a big-picture idea of what works and what doesn’t, and a capable teacher can make almost anything work. The question isn’t  homework vs. no homework ; instead, we should be asking ourselves, “How can we transform homework so that it’s engaging and relevant and supports learning?”

What we know about online learning and the homework gap amid the pandemic.

America’s K-12 students are returning to classrooms this fall after 18 months of virtual learning at home during the COVID-19 pandemic. Some students who lacked the home internet connectivity needed to finish schoolwork during this time – an experience often called the “ homework gap ” – may continue to feel the effects this school year.

Here is what Pew Research Center surveys found about the students most likely to be affected by the homework gap and their experiences learning from home.

Children across the United States are returning to physical classrooms this fall after 18 months at home, raising questions about how digital disparities at home will affect the existing homework gap between certain groups of students.

Methodology for each Pew Research Center poll can be found at the links in the post.

With the exception of the 2018 survey, everyone who took part in the surveys is a member of the Center’s American Trends Panel (ATP), an online survey panel that is recruited through national, random sampling of residential addresses. This way nearly all U.S. adults have a chance of selection. The survey is weighted to be representative of the U.S. adult population by gender, race, ethnicity, partisan affiliation, education and other categories. Read more about the  ATP’s methodology .

The 2018 data on U.S. teens comes from a Center poll of 743 U.S. teens ages 13 to 17 conducted March 7 to April 10, 2018, using the NORC AmeriSpeak panel. AmeriSpeak is a nationally representative, probability-based panel of the U.S. household population. Randomly selected U.S. households are sampled with a known, nonzero probability of selection from the NORC National Frame, and then contacted by U.S. mail, telephone or face-to-face interviewers.

Around nine-in-ten U.S. parents with K-12 children at home (93%) said their children have had some online instruction since the coronavirus outbreak began in February 2020, and 30% of these parents said it has been very or somewhat difficult for them to help their children use technology or the internet as an educational tool, according to an April 2021 Pew Research Center survey .

Gaps existed for certain groups of parents. For example, parents with lower and middle incomes (36% and 29%, respectively) were more likely to report that this was very or somewhat difficult, compared with just 18% of parents with higher incomes.

This challenge was also prevalent for parents in certain types of communities – 39% of rural residents and 33% of urban residents said they have had at least some difficulty, compared with 23% of suburban residents.

Around a third of parents with children whose schools were closed during the pandemic (34%) said that their child encountered at least one technology-related obstacle to completing their schoolwork during that time. In the April 2021 survey, the Center asked parents of K-12 children whose schools had closed at some point about whether their children had faced three technology-related obstacles. Around a quarter of parents (27%) said their children had to do schoolwork on a cellphone, 16% said their child was unable to complete schoolwork because of a lack of computer access at home, and another 14% said their child had to use public Wi-Fi to finish schoolwork because there was no reliable connection at home.

Parents with lower incomes whose children’s schools closed amid COVID-19 were more likely to say their children faced technology-related obstacles while learning from home. Nearly half of these parents (46%) said their child faced at least one of the three obstacles to learning asked about in the survey, compared with 31% of parents with midrange incomes and 18% of parents with higher incomes.

Of the three obstacles asked about in the survey, parents with lower incomes were most likely to say that their child had to do their schoolwork on a cellphone (37%). About a quarter said their child was unable to complete their schoolwork because they did not have computer access at home (25%), or that they had to use public Wi-Fi because they did not have a reliable internet connection at home (23%).

A Center survey conducted in April 2020 found that, at that time, 59% of parents with lower incomes who had children engaged in remote learning said their children would likely face at least one of the obstacles asked about in the 2021 survey.

A year into the outbreak, an increasing share of U.S. adults said that K-12 schools have a responsibility to provide all students with laptop or tablet computers in order to help them complete their schoolwork at home during the pandemic. About half of all adults (49%) said this in the spring 2021 survey, up 12 percentage points from a year earlier. An additional 37% of adults said that schools should provide these resources only to students whose families cannot afford them, and just 13% said schools do not have this responsibility.

While larger shares of both political parties in April 2021 said K-12 schools have a responsibility to provide computers to all students in order to help them complete schoolwork at home, there was a 15-point change among Republicans: 43% of Republicans and those who lean to the Republican Party said K-12 schools have this responsibility, compared with 28% last April. In the 2021 survey, 22% of Republicans also said schools do not have this responsibility at all, compared with 6% of Democrats and Democratic leaners.

Even before the pandemic, Black teens and those living in lower-income households were more likely than other groups to report trouble completing homework assignments because they did not have reliable technology access. Nearly one-in-five teens ages 13 to 17 (17%) said they are often or sometimes unable to complete homework assignments because they do not have reliable access to a computer or internet connection, a 2018 Center survey of U.S. teens found.

One-quarter of Black teens said they were at least sometimes unable to complete their homework due to a lack of digital access, including 13% who said this happened to them often. Just 4% of White teens and 6% of Hispanic teens said this often happened to them. (There were not enough Asian respondents in the survey sample to be broken out into a separate analysis.)

A wide gap also existed by income level: 24% of teens whose annual family income was less than $30,000 said the lack of a dependable computer or internet connection often or sometimes prohibited them from finishing their homework, but that share dropped to 9% among teens who lived in households earning $75,000 or more a year.

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 false reports of homework overload in America have spread so far

Confusing debate suggests homework is too much when it’s often too little.

A previous version of this column mistakenly referred to the education nonprofit Challenge Success as College Success. The column has been corrected.

Recently I saw in the Phi Delta Kappan magazine an attack on homework by a California high school junior, Colin McGrath. Writing the piece as a letter to his younger brother , he said:

“In a 2020 Washington Post article , Denise Pope described what she learned from a survey of more than 50,000 high school students: On average, they complete 2.7 hours of homework a night . That means you won’t be able to play on the trampoline anymore, ride your bike, or explore any other facet of life.”

My reaction: Huh??!! I’ve spent two decades trying to dispel the myth that our kids all get too much homework. The truth, according to several scholarly sources, is that U.S. high school homework averages about an hour a night.

What most teenagers do with the rest of their free time has little connection to trampolines, bicycles or other healthy pursuits. Scholars say their favorite leisure activities are watching TV, playing video games or maybe both at the same time.

So I looked for that Sept. 1, 2020, article in my newspaper that McGrath mentioned. McGrath quoted Pope correctly. I missed that piece when it came out. Maybe most people did. I looked for Wikipedia’s official answer to this frequently asked question: How much time does the average teenager spend on homework?

I was horrified by what I saw, delivered to millions of Wikipedia users: “High schoolers reported doing an average of 2.7 hours of homework per weeknight, according to a study by The Washington Post from 2018 to 2020 of over 50,000 individuals.”

That’s wrong, but I am used to widespread falsehoods about homework overload. Otherwise responsible writers and filmmakers seem unable to resist adding to the hysteria. The popular 2009 film documentary “Race to Nowhere,” screened in 47 states and 20 countries, left the impression that young Americans everywhere were buckling under homework’s weight, yet the film never told viewers that the average amount is an just an hour a night.

Why ‘Race to Nowhere’ documentary is wrong

When Sara Bennett, an attorney and activist parent, and Nancy Kalish, a journalist specializing in parenting issues, went on the “Today” show in 2006 to publicize their book “The Case Against Homework: How Homework Is Hurting Our Children and What We Can Do About It,” they said the average homework load had “skyrocketed.” They used that same word in their book.

They were sensationalizing the fact that the average time 6-to-8-year-olds spent on homework went from eight minutes a day in 1981 to 22 minutes a day in 2003. That supposedly awful demand on their time was the equivalent of watching two episodes of “SpongeBob SquarePants.”

The University of Michigan Institute for Social Research reported in 2003 an average of 50 minutes of homework each weekday for 15-to-17-year-olds, based on a nationally representative sample of 2,907 children and adolescents. A 2019 report by the Pew Research Center , based on Bureau of Labor Statistics data, said 15-to-17- year-olds spent on average an hour a day on homework during the school year. The 2019 UCLA Higher Education Research Institute survey of 95,505 college freshmen reported 57 percent of those students, all good enough to get into college, recalled spending five hours or less a week on homework their senior year of high school. Research shows homework has little value in elementary school, but does correlate with higher achievement in high school.

The false notion of teenagers averaging 2.7 hours a night was incorrectly derived from a study by Challenge Success, a nonprofit organization that works on identifying problems and implementing best practices in schools. Pope, the author of the piece in my newspaper, is a co-founder of Challenge Success and a senior lecturer at the Stanford University Graduate School of Education.

Pope is a wonderful writer and scholar whom I have quoted in the past. She can’t be blamed for Wikipedia saying wrongly the Challenge Success study was done by The Post. She also tried to tell readers that her study did NOT use a representative sample of U.S. teens.

She said the students in the study were all from “high-performing schools.” I only wish she had revealed that in the same sentence that she reported the 2.7-hours-per-night homework average. Her note that the study was confined to the best schools appeared in a different paragraph. That may explain why McGrath, Wikipedia and careless people like me failed, at least on first reading, to see that the sample was skewed.

The Weak Case Against Homework

Too much homework can be a problem in high-achieving schools that cater to middle- and upper-class children. But they represent only about half the country. People on my side of the argument would say that three hours of homework a night is fine if the courses raise achievement and college readiness. I don’t think our kids’ favorite pastimes, video games and TV, are as good for them as going deep into those courses. And even three hours of homework leaves another three hours or so each night (plus the weekend) for nonacademic pursuits.

My concern is the less advantaged students who bring the national average down to just one hour a night by doing little or no homework at all. Since 1996 I have been studying hundreds of unusually dedicated public high schools in low-income communities that have raised achievement for their students and made it far more likely they will succeed in college or whatever they do after high school.

Those schools consider homework vital. One of them was led by Deborah Meier, a hero to many progressive educators. She created New York City’s Central Park East High School, where the mostly low-income students heard much about the importance of using time wisely.

“We told our kids … that the school’s explicit work probably required a 40-hour week — maybe more, maybe less,” she said to me. The official school week was about 30 hours. So she kept the school open an extra 10 hours a week — maybe an hour before school, an hour after school and Saturday mornings.

She didn’t call the extra time homework, but made clear it was essential. “Everyone had more to read than could be done while at school — mostly five-plus hours a week,” she said, “and probably another five for exploring and preparing and revising work done during school hours.”

Pope thinks in similar ways. She sees her Challenge Success research “as a way to a much larger conversation about how to create more meaningful and engaging learning, … how to add time for advisory/tutorial and more student to teacher interaction, how to make all the kids in the school feel like they belong and are cared for.”

That will require more than our puny national homework average of an hour a night, after an inadequate average of five hours of class a day. More learning takes time. One step in the right direction would be accepting the need for regular homework, particularly in high school, and dispensing with falsehoods about giving kids too much to learn.

Part II of the 2014 Brown Center Report on American Education

Homework!  The topic, no, just the word itself, sparks controversy.  It has for a long time. In 1900, Edward Bok, editor of the Ladies Home Journal , published an impassioned article, “A National Crime at the Feet of Parents,” accusing homework of destroying American youth.  Drawing on the theories of his fellow educational progressive, psychologist G. Stanley Hall (who has since been largely discredited), Bok argued that study at home interfered with children’s natural inclination towards play and free movement, threatened children’s physical and mental health, and usurped the right of parents to decide activities in the home.

The Journal was an influential magazine, especially with parents.  An anti-homework campaign burst forth that grew into a national crusade. [i]   School districts across the land passed restrictions on homework, culminating in a 1901 statewide prohibition of homework in California for any student under the age of 15.  The crusade would remain powerful through 1913, before a world war and other concerns bumped it from the spotlight.  Nevertheless, anti-homework sentiment would remain a touchstone of progressive education throughout the twentieth century.  As a political force, it would lie dormant for years before bubbling up to mobilize proponents of free play and “the whole child.” Advocates would, if educators did not comply, seek to impose homework restrictions through policy making.

Our own century dawned during a surge of anti-homework sentiment. From 1998 to 2003, Newsweek , TIME , and People , all major national publications at the time, ran cover stories on the evils of homework.  TIME ’s 1999 story had the most provocative title, “The Homework Ate My Family: Kids Are Dazed, Parents Are Stressed, Why Piling On Is Hurting Students.” People ’s 2003 article offered a call to arms: “Overbooked: Four Hours of Homework for a Third Grader? Exhausted Kids (and Parents) Fight Back.” Feature stories about students laboring under an onerous homework burden ran in newspapers from coast to coast. Photos of angst ridden children became a journalistic staple.

The 2003 Brown Center Report on American Education included a study investigating the homework controversy.  Examining the most reliable empirical evidence at the time, the study concluded that the dramatic claims about homework were unfounded.  An overwhelming majority of students, at least two-thirds, depending on age, had an hour or less of homework each night.  Surprisingly, even the homework burden of college-bound high school seniors was discovered to be rather light, less than an hour per night or six hours per week. Public opinion polls also contradicted the prevailing story.  Parents were not up in arms about homework.  Most said their children’s homework load was about right.  Parents wanting more homework out-numbered those who wanted less.

Now homework is in the news again.  Several popular anti-homework books fill store shelves (whether virtual or brick and mortar). [ii]   The documentary Race to Nowhere depicts homework as one aspect of an overwrought, pressure-cooker school system that constantly pushes students to perform and destroys their love of learning.  The film’s website claims over 6,000 screenings in more than 30 countries.  In 2011, the New York Times ran a front page article about the homework restrictions adopted by schools in Galloway, NJ, describing “a wave of districts across the nation trying to remake homework amid concerns that high stakes testing and competition for college have fueled a nightly grind that is stressing out children and depriving them of play and rest, yet doing little to raise achievement, especially in elementary grades.”   In the article, Vicki Abeles, the director of Race to Nowhere , invokes the indictment of homework lodged a century ago, declaring, “The presence of homework is negatively affecting the health of our young people and the quality of family time.” [iii] 

A petition for the National PTA to adopt “healthy homework guidelines” on change.org currently has 19,000 signatures.  In September 2013, Atlantic featured an article, “My Daughter’s Homework is Killing Me,” by a Manhattan writer who joined his middle school daughter in doing her homework for a week.  Most nights the homework took more than three hours to complete.

The Current Study

A decade has passed since the last Brown Center Report study of homework, and it’s time for an update.  How much homework do American students have today?  Has the homework burden increased, gone down, or remained about the same?  What do parents think about the homework load?

A word on why such a study is important.  It’s not because the popular press is creating a fiction.  The press accounts are built on the testimony of real students and real parents, people who are very unhappy with the amount of homework coming home from school.  These unhappy people are real—but they also may be atypical.  Their experiences, as dramatic as they are, may not represent the common experience of American households with school-age children.  In the analysis below, data are analyzed from surveys that are methodologically designed to produce reliable information about the experiences of all Americans.  Some of the surveys have existed long enough to illustrate meaningful trends.  The question is whether strong empirical evidence confirms the anecdotes about overworked kids and outraged parents.

Data from the National Assessment of Educational Progress (NAEP) provide a good look at trends in homework for nearly the past three decades.  Table 2-1 displays NAEP data from 1984-2012.  The data are from the long-term trend NAEP assessment’s student questionnaire, a survey of homework practices featuring both consistently-worded questions and stable response categories.  The question asks: “How much time did you spend on homework yesterday?”  Responses are shown for NAEP’s three age groups: 9, 13, and 17. [iv]

Today’s youngest students seem to have more homework than in the past.  The first three rows of data for age 9 reveal a shift away from students having no homework, declining from 35% in 1984 to 22% in 2012.  A slight uptick occurred from the low of 18% in 2008, however, so the trend may be abating.  The decline of the “no homework” group is matched by growth in the percentage of students with less than an hour’s worth, from 41% in 1984 to 57% in 2012. The share of students with one to two hours of homework changed very little over the entire 28 years, comprising 12% of students in 2012.  The group with the heaviest load, more than two hours of homework, registered at 5% in 2012.  It was 6% in 1984.

The amount of homework for 13-year-olds appears to have lightened slightly. Students with one to two hours of homework declined from 29% to 23%.  The next category down (in terms of homework load), students with less than an hour, increased from 36% to 44%.  One can see, by combining the bottom two rows, that students with an hour or more of homework declined steadily from 1984 to 2008 (falling from 38% to 27%) and then ticked up to 30% in 2012.  The proportion of students with the heaviest load, more than two hours, slipped from 9% in 1984 to 7% in 2012 and ranged between 7-10% for the entire period.

For 17-year-olds, the homework burden has not varied much.  The percentage of students with no homework has increased from 22% to 27%.  Most of that gain occurred in the 1990s. Also note that the percentage of 17-year-olds who had homework but did not do it was 11% in 2012, the highest for the three NAEP age groups.  Adding that number in with the students who didn’t have homework in the first place means that more than one-third of seventeen year olds (38%) did no homework on the night in question in 2012.  That compares with 33% in 1984.  The segment of the 17-year-old population with more than two hours of homework, from which legitimate complaints of being overworked might arise, has been stuck in the 10%-13% range.

The NAEP data point to four main conclusions:

• With one exception, the homework load has remained remarkably stable since 1984.
• The exception is nine-year-olds.  They have experienced an increase in homework, primarily because many students who once did not have any now have some.  The percentage of nine-year-olds with no homework fell by 13 percentage points, and the percentage with less than an hour grew by 16 percentage points.
• 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.
• NAEP data do not support the idea that a large and growing number of students have an onerous amount of homework.  For all three age groups, only a small percentage of students report more than two hours of homework.  For 1984-2012, the size of the two hours or more groups ranged from 5-6% for age 9, 6-10% for age 13, and 10-13% for age 17.

Note that the item asks students how much time they spent on homework “yesterday.”  That phrasing has the benefit of immediacy, asking for an estimate of precise, recent behavior rather than an estimate of general behavior for an extended, unspecified period.  But misleading responses could be generated if teachers lighten the homework of NAEP participants on the night before the NAEP test is given.  That’s possible. [v] Such skewing would not affect trends if it stayed about the same over time and in the same direction (teachers assigning less homework than usual on the day before NAEP).  Put another way, it would affect estimates of the amount of homework at any single point in time but not changes in the amount of homework between two points in time.

A check for possible skewing is to compare the responses above with those to another homework question on the NAEP questionnaire from 1986-2004 but no longer in use. [vi]   It asked students, “How much time do you usually spend on homework each day?” Most of the response categories have different boundaries from the “last night” question, making the data incomparable.  But the categories asking about no homework are comparable.  Responses indicating no homework on the “usual” question in 2004 were: 2% for age 9-year-olds, 5% for 13 year olds, and 12% for 17-year-olds.  These figures are much less than the ones reported in Table 2-1 above.  The “yesterday” data appear to overstate the proportion of students typically receiving no homework.

The story is different for the “heavy homework load” response categories.  The “usual” question reported similar percentages as the “yesterday” question.  The categories representing the most amount of homework were “more than one hour” for age 9 and “more than two hours” for ages 13 and 17.   In 2004, 12% of 9-year-olds said they had more than one hour of daily homework, while 8% of 13-year-olds and 12% of 17-year-olds said they had more than two hours.  For all three age groups, those figures declined from1986 to 2004. The decline for age 17 was quite large, falling from 17% in 1986 to 12% in 2004.  

The bottom line: regardless of how the question is posed, NAEP data do not support the view that the homework burden is growing, nor do they support the belief that the proportion of students with a lot of homework has increased in recent years.  The proportion of students with no homework is probably under-reported on the long-term trend NAEP.  But the upper bound of students with more than two hours of daily homework appears to be about 15%–and that is for students in their final years of high school.

College Freshmen Look Back  

There is another good source of information on high school students’ homework over several decades.  The Higher Education Research Institute at UCLA conducts an annual survey of college freshmen that began in 1966.  In 1986, the survey started asking a series of questions regarding how students spent time in the final year of high school.  Figure 2-1 shows the 2012 percentages for the dominant activities.  More than half of college freshmen say they spent at least six hours per week socializing with friends (66.2%) and exercising/sports (53.0%).  About 40% devoted that much weekly time to paid employment.

Homework comes in fourth pace. Only 38.4% of students said they spent at least six hours per week studying or doing homework. When these students were high school seniors, it was not an activity central to their out of school lives.  That is quite surprising.  Think about it.  The survey is confined to the nation’s best students, those attending college.  Gone are high school dropouts.  Also not included are students who go into the military or attain full time employment immediately after high school.  And yet only a little more than one-third of the sampled students, devoted more than six hours per week to homework and studying when they were on the verge of attending college.

Another notable finding from the UCLA survey is how the statistic is trending (see Figure 2-2).  In 1986, 49.5% reported spending six or more hours per week studying and doing homework.  By 2002, the proportion had dropped to 33.4%.  In 2012, as noted in Figure 2-1, the statistic had bounced off the historical lows to reach 38.4%.  It is slowly rising but still sits sharply below where it was in 1987.

What Do Parents Think?

Met Life has published an annual survey of teachers since 1984.  In 1987 and 2007, the survey included questions focusing on homework and expanded to sample both parents and students on the topic. Data are broken out for secondary and elementary parents and for students in grades 3-6 and grades 7-12 (the latter not being an exact match with secondary parents because of K-8 schools).

Table 2-2 shows estimates of homework from the 2007 survey.  Respondents were asked to estimate the amount of homework on a typical school day (Monday-Friday).  The median estimate of each group of respondents is shaded.  As displayed in the first column, the median estimate for parents of an elementary student is that their child devotes about 30 minutes to homework on the typical weekday.  Slightly more than half (52%) estimate 30 minutes or less; 48% estimate 45 minutes or more.  Students in grades 3-6 (third column) give a median estimate that is a bit higher than their parents’ (45 minutes), with almost two-thirds (63%) saying 45 minutes or less is the typical weekday homework load.

One hour of homework is the median estimate for both secondary parents and students in grade 7-12, with 55% of parents reporting an hour or less and about two-thirds (67%) of students reporting the same.  As for the prevalence of the heaviest homework loads, 11% of secondary parents say their children spend more than two hours on weekday homework, and 12% is the corresponding figure for students in grades 7-12.

The Met Life surveys in 1987 and 2007 asked parents to evaluate the amount and quality of homework.  Table 2-3 displays the results.  There was little change over the two decades separating the two surveys.  More than 60% of parents rate the amount of homework as good or excellent, and about two-thirds give such high ratings to the quality of the homework their children are receiving.  The proportion giving poor ratings to either the quantity or quality of homework did not exceed 10% on either survey.

Parental dissatisfaction with homework comes in two forms: those who feel schools give too much homework and those who feel schools do not give enough.  The current wave of journalism about unhappy parents is dominated by those who feel schools give too much homework.  How big is this group?  Not very big (see Figure 2-3). On the Met Life survey, 60% of parents felt schools were giving the right amount of homework, 25% wanted more homework, and only 15% wanted less.

National surveys on homework are infrequent, but the 2006-2007 period had more than one.  A poll conducted by Public Agenda in 2006 reported similar numbers as the Met Life survey: 68% of parents describing the homework load as “about right,” 20% saying there is “too little homework,” and 11% saying there is “too much homework.”  A 2006 AP-AOL poll found the highest percentage of parents reporting too much homework, 19%.  But even in that poll, they were outnumbered by parents believing there is too little homework (23%), and a clear majority (57%) described the load as “about right.”  A 2010 local survey of Chicago parents conducted by the Chicago Tribune reported figures similar to those reported above: approximately two-thirds of parents saying their children’s homework load is “about right,” 21% saying it’s not enough, and 12% responding that the homework load is too much.

Summary and Discussion

In recent years, the press has been filled with reports of kids over-burdened with homework and parents rebelling against their children’s oppressive workload. The data assembled above call into question whether that portrait is accurate for the typical American family.  Homework typically takes an hour per night.  The homework burden of students rarely exceeds two hours a night.  The upper limit of students with two or more hours per night is about 15% nationally—and that is for juniors or seniors in high school.  For younger children, the upper boundary is about 10% who have such a heavy load.  Polls show that parents who want less homework range from 10%-20%, and that they are outnumbered—in every national poll on the homework question—by parents who want more homework, not less.  The majority of parents describe their children’s homework burden as about right.

So what’s going on?  Where are the homework horror stories coming from?

The Met Life survey of parents is able to give a few hints, mainly because of several questions that extend beyond homework to other aspects of schooling.  The belief that homework is burdensome is more likely held by parents with a larger set of complaints and concerns.  They are alienated from their child’s school.  About two in five parents (19%) don’t believe homework is important.  Compared to other parents, these parents are more likely to say too much homework is assigned (39% vs. 9%), that what is assigned is just busywork (57% vs. 36%), and that homework gets in the way of their family spending time together (51% vs. 15%).  They are less likely to rate the quality of homework as excellent (3% vs. 23%) or to rate the availability and responsiveness of teachers as excellent (18% vs. 38%). [vii]

They can also convince themselves that their numbers are larger than they really are.  Karl Taro Greenfeld, the author of the Atlantic article mentioned above, seems to fit that description.  “Every parent I know in New York City comments on how much homework their children have,” Mr. Greenfeld writes.  As for those parents who do not share this view? “There is always a clique of parents who are happy with the amount of homework. In fact, they would prefer more .  I tend not to get along with that type of parent.” [viii] 

Mr. Greenfeld’s daughter attends a selective exam school in Manhattan, known for its rigorous expectations and, yes, heavy homework load.  He had also complained about homework in his daughter’s previous school in Brentwood, CA.  That school was a charter school.  After Mr. Greenfeld emailed several parents expressing his complaints about homework in that school, the school’s vice-principal accused Mr. Greenfeld of cyberbullying.  The lesson here is that even schools of choice are not immune from complaints about homework.

The homework horror stories need to be read in a proper perspective.  They seem to originate from the very personal discontents of a small group of parents.  They do not reflect the experience of the average family with a school-age child.  That does not diminish these stories’ power to command the attention of school officials or even the public at large. But it also suggests a limited role for policy making in settling such disputes.  Policy is a blunt instrument.  Educators, parents, and kids are in the best position to resolve complaints about homework on a case by case basis.  Complaints about homework have existed for more than a century, and they show no signs of going away.

[v] NAEP’s sampling design lessens the probability of skewing the homework figure.  Students are randomly drawn from a school population, meaning that an entire class is not tested.  Teachers would have to either single out NAEP students for special homework treatment or change their established homework routine for the whole class just to shelter NAEP participants from homework.  Sampling designs that draw entact classrooms for testing (such as TIMSS) would be more vulnerable to this effect.  Moreover, students in middle and high school usually have several different teachers during the day, meaning that prior knowledge of a particular student’s participation in NAEP would probably be limited to one or two teachers.

The instructor takes her sample by gathering data on five randomly selected students from each Lake Tahoe Community College math class. The type of sampling she used is

• cluster sampling
• stratified sampling
• simple random sampling
• convenience sampling

A study was done to determine the age, number of times per week, and the duration (amount of time) of residents using a local park in San Jose. The first house in the neighborhood around the park was selected randomly and then every eighth house in the neighborhood around the park was interviewed. The sampling method was:

• simple random

Name the sampling method used in each of the following situations:

• A woman in the airport is handing out questionnaires to travelers asking them to evaluate the airport’s service. She does not ask travelers who are hurrying through the airport with their hands full of luggage, but instead asks all travelers who are sitting near gates and not taking naps while they wait.
• A teacher wants to know if her students are doing homework, so she randomly selects rows two and five and then calls on all students in row two and all students in row five to present the solutions to homework problems to the class.
• The marketing manager for an electronics chain store wants information about the ages of its customers. Over the next two weeks, at each store location, 100 randomly selected customers are given questionnaires to fill out asking for information about age, as well as about other variables of interest.
• The librarian at a public library wants to determine what proportion of the library users are children. The librarian has a tally sheet on which she marks whether books are checked out by an adult or a child. She records this data for every fourth patron who checks out books.
• A political party wants to know the reaction of voters to a debate between the candidates. The day after the debate, the party’s polling staff calls 1,200 randomly selected phone numbers. If a registered voter answers the phone or is available to come to the phone, that registered voter is asked whom he or she intends to vote for and whether the debate changed his or her opinion of the candidates.

A “random survey” was conducted of 3,274 people of the “microprocessor generation” (people born since 1971, the year the microprocessor was invented). It was reported that 48% of those individuals surveyed stated that if they had $2,000 to spend, they would use it for computer equipment. Also, 66% of those surveyed considered themselves relatively savvy computer users.

• Do you consider the sample size large enough for a study of this type? Why or why not?
• Based on your “gut feeling,” do you believe the percents accurately reflect the U.S. population for those individuals born since 1971? If not, do you think the percents of the population are actually higher or lower than the sample statistics? Why? Additional information: The survey, reported by Intel Corporation, was filled out by individuals who visited the Los Angeles Convention Center to see the Smithsonian Institute's road show called “America’s Smithsonian.”
• With this additional information, do you feel that all demographic and ethnic groups were equally represented at the event? Why or why not?
• With the additional information, comment on how accurately you think the sample statistics reflect the population parameters.

The Well-Being Index is a survey that follows trends of U.S. residents on a regular basis. There are six areas of health and wellness covered in the survey: Life Evaluation, Emotional Health, Physical Health, Healthy Behavior, Work Environment, and Basic Access. Some of the questions used to measure the Index are listed below.

Identify the type of data obtained from each question used in this survey: qualitative, quantitative discrete, or quantitative continuous.

• Do you have any health problems that prevent you from doing any of the things people your age can normally do?
• During the past 30 days, for about how many days did poor health keep you from doing your usual activities?
• In the last seven days, on how many days did you exercise for 30 minutes or more?
• Do you have health insurance coverage?

In advance of the 1936 Presidential Election, a magazine titled Literary Digest released the results of an opinion poll predicting that the republican candidate Alf Landon would win by a large margin. The magazine sent post cards to approximately 10,000,000 prospective voters. These prospective voters were selected from the subscription list of the magazine, from automobile registration lists, from phone lists, and from club membership lists. Approximately 2,300,000 people returned the postcards.

• Think about the state of the United States in 1936. Explain why a sample chosen from magazine subscription lists, automobile registration lists, phone books, and club membership lists was not representative of the population of the United States at that time.
• What effect does the low response rate have on the reliability of the sample?
• Are these problems examples of sampling error or nonsampling error?
• During the same year, George Gallup conducted his own poll of 30,000 prospective voters. These researchers used a method they called "quota sampling" to obtain survey answers from specific subsets of the population. Quota sampling is an example of which sampling method described in this module?

Crime-related and demographic statistics for 47 US states in 1960 were collected from government agencies, including the FBI's Uniform Crime Report . One analysis of this data found a strong connection between education and crime indicating that higher levels of education in a community correspond to higher crime rates.

Which of the potential problems with samples discussed in 1.2 Data, Sampling, and Variation in Data and Sampling could explain this connection?

YouPolls is a website that allows anyone to create and respond to polls. One question posted April 15 asks:

“Do you feel happy paying your taxes when members of the Obama administration are allowed to ignore their tax liabilities?” (lastbaldeagle. 2013. On Tax Day, House to Call for Firing Federal Workers Who Owe Back Taxes. Opinion poll posted online at: http://www.youpolls.com/details.aspx?id=12328 (accessed May 1, 2013).)

As of April 25, 11 people responded to this question. Each participant answered “NO!”

Which of the potential problems with samples discussed in this module could explain this connection?

A scholarly article about response rates begins with the following quote:

The Pew Research Center for People and the Press admits:

“The percentage of people we interview – out of all we try to interview – has been declining over the past decade or more.” (Frequently Asked Questions, Pew Research Center for the People & the Press, http://www.people-press.org/methodology/frequently-asked-questions/#dont-you-have-trouble-getting-people-to-answer-your-polls (accessed May 1, 2013).)

Is it time to get rid of homework? Mental health experts weigh in

by Sara M Moniuszko

It's no secret that kids hate homework. 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 over 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."

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.

"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 also taught third to 12th graders 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 the French students (and) the French schools, because that was helping the students to really have the time off and really 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 high-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.

The pandemic made the conversation around homework more crucial

Mindfulness surrounding homework is especially important in the context of the last two years. Many students will be struggling with mental health issues that were brought on or worsened by the pandemic, making heavy workloads even harder to balance.

"COVID was just a disaster in terms of the lack of structure. Everything just deteriorated," Kardaras says, pointing to an increase in cognitive issues and decrease in attention spans among students. "School acts as an anchor for a lot of children, as a stabilizing force, and that disappeared."

But even if students transition back to the structure of in-person classes, Kardaras suspects students may still struggle after two school years of shifted schedules and disrupted sleeping habits.

"We've seen adults struggling to go back to in-person work environments from remote work environments. That effect is amplified with children because children have less resources to be able to cope with those transitions than adults do," he explains.

'Get organized' ahead of back-to-school

In order to make the transition back to in-person school easier, Kang encourages students to "get good sleep, exercise regularly (and) eat a healthy diet."

To help manage workloads, she suggests students "get organized."

"There's so much mental clutter up there when you're disorganized... sitting down and planning out their study schedules can really help manage their time," she says.

Breaking assignments up can also make things easier to tackle.

"I know that heavy workloads can be stressful, but if you sit down and you break down that studying into smaller chunks, they're much more manageable."

If workloads are still too much, Kang encourages students to advocate for themselves.

"They should tell their teachers when a homework assignment just took too much time or if it was too difficult for them to do on their own," she says. "It's good to speak up and ask those questions. Respectfully, of course, because these are your teachers. But still, I think sometimes teachers themselves need this feedback from their students."
