Research About Too Much Homework Is Bad


Stevie Naeyaert

Ask an eleven-year-old whether homework is a bad thing, and you'll likely be greeted with vigorous nodding and not a hint of ambiguity. But do grown-up experts agree?

As with so many things, the answer is mixed.

"Very simply, too much of anything can be harmful," says Gerald LeTendre, head of Penn State's Education Policy Studies department. "What Harris Cooper has advised—and he's one of the leading researchers who has some very good, accessible books on the subject—is it's best to have no homework for kindergarten through second grade, and then maybe 10 minutes per day, increasing by 10 minutes as you go up each grade, so that you're up to an hour or hour and a half of homework by middle school."

More than that and there can be negative effects, studies suggest. Overburdened by homework, children may become disillusioned with school and lose motivation. And excessive homework can interfere with time otherwise spent connecting as a family by playing games, taking walks, or just talking about the day. This was a complaint LeTendre heard frequently as he conducted studies of homework amount and frequency.

Among other things, these studies found that the popular opinion that America does less homework than other nations is simply not true. "There are myths about the "lazy Americans," LeTendre notes, "but our findings about amount of homework were that the U.S. tends to be in the middle, not too far to one end or the other."

"Lyn Corno at Columbia University had an article that said 'homework is a complicated thing,' says LeTendre. "We think of homework as something very simple, almost like an afterthought. It's not. It can be a very effective tool, but it is complicated."

One of the complicating factors is age. "Most small children and early adolescents have not yet developed the kind of self-reflective or self-monitoring skills to get the benefit out of either homework or self study," Le Tendre explains. "But as you move into high school, individuals are increasingly self-aware and can better self-monitor."

But age alone will not predict the usefulness of homework. "If the homework isn't addressing the child's actual academic problem, the child is going to continue to fall further behind and get hopelessly lost," LeTendre cautions.

The problem, he adds, is that most teachers use "the shotgun approach," photocopying worksheets and giving each student the same assignment. And many neglect to go over the homework after it's completed, opting instead to merely check off whether or not it was done at all.

"That's not very effective," says LeTendre. "Let's say you assigned a worksheet on addition of two-digit numbers. If that's what the child's been having difficulty with, then maybe the child, by doing it over and over, can figure it out and make some improvements. But maybe not. Maybe the child still doesn't get it and you need to talk about carrying the one. Or maybe the child knows how to do it and is bored to tears. If there's no feedback and no monitoring, the homework is probably not effective."

What is effective, believes LeTendre, is identifying the specific area where the child needs skill-building work, assigning that homework at an individual level, and then going over it with the child at regular periods to be certain that they're making progress.

"That kind of homework is exemplary," notes LeTendre, "and you don't see it very much."

The more teachers individualize homework, in terms of its focus and monitoring, the better, LeTendre says, and the same goes for parental monitoring. There is no one-size-fits-all approach, and the level of parental involvement that suits your ten year-old may not suit your teenager. Recent studies have found that parental involvement may be positive for elementary and high school students, but negative for middle school kids. "In other words," laughs LeTendre, "don't nag your pubescent children about homework. Kind of common sense."

What's important at all ages is communication. Figuring out what the best homework is takes some time and a little bit of research on the part of both parents and of teachers. According to LeTendre, it is crucial for parents and teachers to be on the same page.

"Read Harris Cooper's books, such as The Battle Over Homework. That would be my first recommendation for parents," he says. "The other would be to go talk to the teacher. Ask the teacher to clarify the goals for this homework. Ask what the expectations are for the parents, and then be up-front with the teacher about what effect this has on the family. Try to negotiate something that works for everyone."

Unfortunately—at least from the perspective of your eleven-year-old—there will still likely be some amount of homework involved.

From kindergarten to the final years of high school, recent research suggests that some students are getting excessive amounts of homework.

In turn, when students are pushed to handle a workload that’s out of sync with their development level, it can lead to significant stress — for children and their parents.

Both the National Education Association (NEA) and the National PTA (NPTA) support a standard of “10 minutes of homework per grade level” and setting a general limit on after-school studying.

For kids in first grade, that means 10 minutes a night, while high school seniors could get two hours of work per night.

But the most recent study to examine the issue found that kids in early elementary school received about three times the amount of recommended homework.

Published in The American Journal of Family Therapy, the 2015 study surveyed more than 1,100 parents in Rhode Island with school-age children.

The researchers found that first and second graders received 28 and 29 minutes of homework per night.

Kindergarteners received 25 minutes of homework per night, on average. But according to the standards set by the NEA and NPTA, they shouldn’t receive any at all.

A contributing editor of the study, Stephanie Donaldson-Pressman, told CNN that she found it “absolutely shocking” to learn that kindergarteners had that much homework.

And all those extra assignments may lead to family stress, especially when parents with limited education aren’t confident in their ability to help kids with the work.

The researchers reported that family fights about homework were 200 percent more likely when parents didn’t have a college degree.

Some parents, in fact, have decided to opt out of the whole thing. The Washington Post reported in 2016 that some parents have just instructed their younger children not to do their homework assignments.

They report the no-homework policy has taken the stress out of their afternoons and evenings. In addition, it's been easier for their children to participate in after-school activities.

This new parental directive may be healthier for children, too.

Experts say there may be real downsides for young kids who are pushed to do more homework than the “10 minutes per grade” standard.

“The data shows that homework over this level is not only not beneficial to children’s grades or GPA, but there’s really a plethora of evidence that it’s detrimental to their attitude about school, their grades, their self-confidence, their social skills, and their quality of life,” Donaldson-Pressman told CNN.

Consequences for high school students

Other studies have found that high school students may also be overburdened with homework — so much that it’s taking a toll on their health.

In 2013, research conducted at Stanford University found that students in high-achieving communities who spend too much time on homework experience more stress, physical health problems, a lack of balance in their lives, and alienation from society.

That study, published in The Journal of Experimental Education, suggested that any more than two hours of homework per night is counterproductive.

However, students who participated in the study reported doing slightly more than three hours of homework each night, on average.

To conduct the study, researchers surveyed more than 4,300 students at 10 high-performing high schools in upper middle-class California communities. They also interviewed students about their views on homework.

When it came to stress, more than 70 percent of students said they were “often or always stressed over schoolwork,” with 56 percent listing homework as a primary stressor. Less than 1 percent of the students said homework was not a stressor.

The researchers asked students whether they experienced physical symptoms of stress, such as headaches, exhaustion, sleep deprivation, weight loss, and stomach problems.

More than 80 percent of students reported having at least one stress-related symptom in the past month, and 44 percent said they had experienced three or more symptoms.

The researchers also found that spending too much time on homework meant that students were not meeting their developmental needs or cultivating other critical life skills. Students were more likely to forgo activities, stop seeing friends or family, and not participate in hobbies.

Many students felt forced or obligated to choose homework over developing other talents or skills.

"Our findings on the effects of homework challenge the traditional assumption that homework is inherently good," said Denise Pope, Ph.D., a senior lecturer at the Stanford University School of Education, and a co-author of a study.

Working as hard as adults

A smaller New York University study published last year noted similar findings.

It focused more broadly on how students at elite private high schools cope with the combined pressures of school work, college applications, extracurricular activities, and parents’ expectations.

That study, which appeared in Frontiers in Psychology, noted serious health effects for high schoolers, such as chronic stress, emotional exhaustion, and alcohol and drug use.

The research involved a series of interviews with students, teachers, and administrators, as well as a survey of a total of 128 juniors from two private high schools.

About half of the students said they received at least three hours of homework per night. They also faced pressure to take college-level classes and excel in activities outside of school.

Many students felt they were being asked to work as hard as adults, and noted that their workload seemed inappropriate for their development level. They reported having little time for relaxing or creative activities.

More than two-thirds of students said they used alcohol and drugs, primarily marijuana, to cope with stress.

The researchers expressed concern that students at high-pressure high schools can get burned out before they even get to college.

“School, homework, extracurricular activities, sleep, repeat — that’s what it can be for some of these students,” said Noelle Leonard, Ph.D., a senior research scientist at the New York University College of Nursing, and lead study author, in a press release.

What can be done?

Experts continue to debate the benefits and drawbacks of homework.

But according to an article published this year in Monitor on Psychology, there’s one thing they agree on: the quality of homework assignments matters.

In the Stanford study, many students said that they often did homework they saw as "pointless" or "mindless."

Pope, who co-authored that study, argued that homework assignments should have a purpose and benefit, and should be designed to cultivate learning and development.

It’s also important for schools and teachers to stick to the 10-minutes per grade standard.

In an interview with Monitor on Psychology, Pope pointed out that students can learn challenging skills even when less homework is assigned.

Pope described one teacher she worked with who taught advanced placement biology, and experimented by dramatically cutting down homework assignments. First the teacher cut homework by a third, and then cut the assignments in half.

The students’ test scores didn’t change.

“You can have a rigorous course and not have a crazy homework load,” Pope said.
