Homework isn't fun for students to do or for teachers to grade, so why do it? Here are some reasons why homework is good and why it's bad.

Why Homework Is Good

Here are 10 reasons why homework is good, especially for the sciences, such as chemistry:

  • Doing homework teaches you how to learn on your own and work independently. You'll learn how to use resources such as texts, libraries, and the internet. No matter how well you thought you understood the material in class, there will be times when you'll get stuck doing homework. When you face the challenge, you learn how to get help, how to deal with frustration, and how to persevere.
  • Homework helps you learn beyond the scope of the class. Example problems from teachers and textbooks show you how to do an assignment. The acid test is seeing whether you truly understand the material and can do the work on your own. In science classes, homework problems are critically important. You see concepts in a whole new light, so you'll know how equations work in general, not just how they work for a particular example. In chemistry, physics, and math, homework is truly important and not just busywork.
  • It shows you what the teacher thinks is important to learn, so you'll have a better idea of what to expect on a quiz or test .
  • It's often a significant part of your grade . If you don't do it, it could cost you , no matter how well you do on exams.
  • Homework is a good opportunity to connect parents, classmates, and siblings with your education. The better your support network, the more likely you are to succeed in class.
  • Homework, however tedious it might be, teaches responsibility and accountability. For some classes, homework is an essential part of learning the subject matter.
  • Homework nips procrastination in the bud. One reason teachers give homework and attach a big part of your grade to it is to motivate you to keep up. If you fall behind, you could fail.
  • How will you get all your work done before class? Homework teaches you time management and how to prioritize tasks.
  • Homework reinforces the concepts taught in class. The more you work with them, the more likely you are to learn them. 
  • Homework can help boost self-esteem . Or, if it's not going well, it helps you identify problems before they get out of control.

Sometimes Homework Is Bad

So, homework is good because it can boost your grades , help you learn the material, and prepare you for tests. It's not always beneficial, however. Sometimes homework hurts more than it helps. Here are five ways homework can be bad:

  • You need a break from a subject so you don't burn out or lose interest. Taking a break helps you learn.
  • Too much homework can lead to copying and cheating.
  • Homework that is pointless busywork can lead to a negative impression of a subject (not to mention a teacher).
  • It takes time away from families, friends, jobs, and other ways to spend your time.
  • Homework can hurt your grades. It forces you to make time management decisions, sometimes putting you in a no-win situation. Do you take the time to do the homework or spend it studying concepts or doing work for another subject? If you don't have the time for the homework, you could hurt your grades even if you ace the tests and understand the subject.

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.”

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.

Kids are onto something: Homework might actually be bad

Do kids actually need homework? Even with increasing amounts of data, it's hard to know if homework is helping or hurting students.

By Stan Horaczek | Published Sep 23, 2021 8:00 AM EDT

A child doing homework at a table

When you’re a kid, your stance on homework is generally pretty simple: It’s the worst. When it comes to educators, parents, and school administrators, however, the topic gets a lot more complicated. 

Collective educational enthusiasm toward homework has ebbed and flowed throughout the 20th century in the US. School districts began abolishing homework in the ‘30s and ‘40s, only for it to come roaring back as the space race kicked off in the late ‘50s and drove a desire for sharper math and science skills. It fell out of fashion again during the Vietnam War era before it came back strong in the ‘80s .

As the country mostly transitions back to full-time, in-person schooling, the available research on homework and its efficacy is still messy at best. 

How much homework are kids doing?

There’s a fundamental issue at the very start of this discussion: we’re not entirely sure how much homework kids are actually doing. A 2019 Pew survey found that teens were spending considerably more time doing schoolwork at home than they had in the past—an hour a day, on average, compared to 44 minutes a decade ago and just 30 in the mid-1990s. 

But other data disagrees , instead suggesting that homework expansion primarily affects children in lower grades. But it’s worth noting that such arguments typically refer to data from more than a decade ago. 

How much homework are kids supposed to be doing?

Many schools subscribe to a “rule of thumb” that suggests students should get 10 minutes of homework for each grade level. So, first graders should get just 10 minutes of work to do at home while high schoolers should be cracking the books for up to two hours each night. 

This once served as the official guidance for educators from the National Education Association, as well as the National PTA. It also serves as the official homework policy for many school districts, even though the NEA’s outline of  the policy now leads to an error page . The National PTA also now relies on a less-specific resolution on homework which encourages districts and educators to focus on “quality over quantity.”

The PTA’s resolution effectively sums up the current dominant perspective on homework. “The National PTA and its constituent associations advocate that teachers, schools, and districts follow evidence-based guidelines regarding the use of homework assignments and its impact on children’s lives and family interactions.”

Even with these well-known standards, a study from researchers at Brown University, Brandeis University, Rhode Island College, Dean College, the Children’s National Medical Center, and the New England Center for Pediatric Psychology, found that younger children were still getting more than the recommended amount of homework by two or three times . First and second graders were doing roughly 30 minutes of homework every night. 

Does homework make kids smarter?

In the mid-2000s, a Duke researcher named Harris Cooper led up one of the most comprehensive looks at homework efficacy to-date. The research set out to explore the perceived correlation between homework and achievement. The results showed a general correlation between homework and achievement. Cooper reported, “No strong evidence was found for an association between the homework–achievement link and the outcome measure (grades as opposed to standardized tests) or the subject matter (reading as opposed to math).” 

The paper does suggest that the correlation strengthens after 7th grade—but it’s likely not a causal relationship. In an interview with the NEA , Cooper explains, “It’s also worth noting that these correlations with older students are likely caused, not only by homework helping achievement but also by kids who have higher achievement levels doing more homework.”

A 2012 study looked at more than 18,000 10th-grade students and concluded that increasing homework loads could be the result of too much material with insufficient instructional time in the classroom. “The overflow typically results in more homework assignments,” the lead researcher said in a statement from the University. “However, students spending more time on something that is not easy to understand or needs to be explained by a teacher does not help these students learn and, in fact, may confuse them.”

Even in that case, however, the research provided somewhat conflicting results that are hard to reconcile. While the study found a positive association between time spent on homework and scores on standardized tests, students who did homework didn’t generally get better grades than kids who didn’t. 

Can homework hurt kids?

It seems antithetical, but some research suggests that homework can actually hinder achievement and, in some cases, students’ overall health. 

A 2013 study looked at a sample of 4,317 students from 10 high-performing high schools in upper middle class communities. The results showed that “students who did more hours of homework experienced greater behavioral engagement in school but also more academic stress, physical health problems, and lack of balance in their lives.” And that’s in affluent districts. 

When you add economic inequity into the equation, homework’s prognosis looks even worse. Research suggests that increased homework can help widen the achievement gap between low-income and economically advantaged students ; the latter group is more likely to have a safe and appropriate place to do schoolwork at night, as well as to have caregivers with the time and academic experience to encourage them to get it done. 

That doesn’t mean financially privileged kids are guaranteed to benefit from hours of worksheets and essays. Literature supporting homework often suggests that it gives parents an opportunity to participate in the educational process as well as monitor a child’s progress and learning. Opponents, however, contest that parental involvement can actually hurt achievement. A 2014 research survey showed that help from parents who have forgotten the material (or who never really understood it) can actually harm a student’s ability to learn. 

The digital homework divide

Access to reliable high-speed internet also presents an unfortunate opportunity for inequity when it comes to at-home learning. Even with COVID-era initiatives expanding programs to provide broadband to underserved areas, millions of households still lack access to fast, reliable internet . 

As more homework assignments migrate to online environments instead of paper, those students without reliable home internet have to make other arrangements to complete their assignments in school or somewhere else outside the home. 

How do we make homework work?

Some experts suggest decoupling homework from students’ overall grades. A 2009 paper suggests that, while homework can be an effective tool for monitoring progress, assigning a grade can actually undercut the main purpose of the work by encouraging students to focus on their scores instead of mastering the material. The study recommends nuanced feedback instead of numbered grades to keep the emphasis on learning—which has the added benefit of minimizing consequences for kids with tougher at-home circumstances. 

Making homework more useful for kids may also come down to picking the right types of assignments. There’s a well-worn concept in psychology known as the spacing effect , which suggests it’s easier to learn material revisited several times in short bursts rather than during long study sessions. This supports the idea that shorter assignments can be more beneficial than heavy workloads.  Many homework opponents add that at-home assignments should appeal to a child’s innate curiosity. It’s easy to find anecdotal evidence from educators who have stopped assigning homework only to find that their students end up participating in more self-guided learning. As kids head back into physical school buildings, the homework debate will no doubt continue on. Hopefully, the research will go with it.

Health Hazards of Homework

March 18, 2014 | Julie Greicius Pediatrics .

student_stress-stanford-childrens

A new study by the Stanford Graduate School of Education and colleagues found that students in high-performing schools who did excessive hours of homework “experienced greater behavioral engagement in school but also more academic stress, physical health problems, and lack of balance in their lives.”

Those health problems ranged from stress, headaches, exhaustion, sleep deprivation, weight loss and stomach problems, to psycho-social effects like dropping activities, not seeing friends or family, and not pursuing hobbies they enjoy.

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

The study was based on survey data from a sample of 4,317 students from 10 high-performing high schools in California communities in which median household income exceeded $90,000. Of the students surveyed, homework volume averaged about 3.1 hours each night.

“It is time to re-evaluate how the school environment is preparing our high school student for today’s workplace,” says Neville Golden, MD , chief of adolescent medicine at Stanford Medicine Children’s Health and a professor at the School of Medicine. “This landmark study shows that excessive homework is counterproductive, leading to sleep deprivation, school stress and other health problems. Parents can best support their children in these demanding academic environments by advocating for them through direct communication with teachers and school administrators about homework load.”
