It used to be that students were the only ones complaining about the practice of assigning homework. For years, teachers and parents thought that homework was a necessary tool when educating children. But studies about the effectiveness of homework have been conflicting and inconclusive, leading some adults to argue that homework should become a thing of the past.

What Research Says about Homework

According to Duke professor Harris Cooper, it's important that students have homework. His meta-analysis of homework studies showed a correlation between completing homework and academic success, at least in older grades. He recommends following a : students should receive 10 minutes of homework per day in first grade, and 10 additional minutes each subsequent year, so that by twelfth grade they are completing 120 minutes of homework daily.

But his analysis didn't prove that students did better because they did homework; it simply . This could simply mean that kids who do homework are more committed to doing well in school. Cooper also found that some research showed that homework caused physical and emotional stress, and created negative attitudes about learning. He suggested that more research needed to be done on homework's effect on kids.

Some researchers say that the question isn't whether kids should have homework. It's more about what kind of homework students have and how much. To be effective, homework has to meet students' needs. For example, some  that's adapted to each student's level of understanding. But when middle school students were assigned more than an hour and a half of homework, their .

Researchers at Indiana University discovered that math and science homework may improve standardized test grades, but they  between students who did homework and those who didn't. These researchers theorize that homework doesn't result in more content mastery, but in greater familiarity with the kinds of questions that appear on standardized tests. According to Professor Adam Maltese, one of the study's authors, "Our results hint that maybe homework is not being used as well as it could be."

So while many teachers and parents support daily homework, it's hard to find strong evidence that the long-held practice produces positive results.

Problems with Homework

In an article in , teacher Samantha Hulsman said she's frequently heard parents complain that a 30-minute homework assignment turns into a three-hour battle with their kids. Now, she's facing the same problem with her own kids, which has her rethinking her former beliefs about homework. "I think parents expect their children to have homework nightly, and teachers assign daily homework because it's what we've always done," she explained. Today, Hulsman said, it's more important to know how to collaborate and solve problems than it is to know specific facts.

Child psychologist Kenneth Barish wrote in Psychology TodayÌý³Ù³ó²¹³ÙÌý. Children who don't do their homework are not lazy, he said, but they may be frustrated, discouraged, or anxious. And for kids with learning disabilities, homework is like "running with a sprained ankle. It's doable, but painful."

Barish suggests that parents and kids have a "homework plan" that limits the time spent on homework. The plan should include turning off all devices—not just the student's, but those belonging to all family members.

One of the , says that some people wrongly believe "kids are like vending machines—put in an assignment, get out learning." Kohn points to the lack of evidence that homework is an effective learning tool; in fact, he calls it "the greatest single extinguisher of children's curiosity that we have yet invented."

Homework Bans

Last year, the public schools in Marion County, Florida, . Instead, kids read nightly for 20 minutes. Superintendent Heidi Maier said the decision was based on Cooper's research showing that elementary students gain little from homework, but a lot from reading.

Orchard Elementary School in South Burlington, Vermont, followed the same path, substituting reading for homework. The : read nightly, go outside and play, have dinner with your family, and get a good night's sleep. Principal Mark Trifilio says that his staff and parents support the idea.

But while many elementary schools are considering no-homework policies, middle schools and high schools have been reluctant to abandon homework. Schools say parents support homework and teachers know it can be helpful when it is specific and follows certain guidelines. For example, practicing solving word problems can be helpful, but there's no reason to assign 50 problems when 10 will do. Recognizing that not all kids have the time, space, and home support to do homework is important, so it shouldn't be counted as part of a student's grade.

So Should Students Have Homework?

Should you ban homework in your classroom? If you teach lower grades, it's possible. If you teach middle or high school, probably not. But all teachers should think carefully about their homework policies. By limiting the amount of homework and improving the quality of assignments, you can improve learning outcomes for your students.
