Research suggests that 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.
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.
But the most recent study to examine the issue found that kids in their study who were 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 talk with the school about their child’s 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.
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 othercritical 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, PhD, a senior lecturer at the Stanford University School of Education, and a co-author of a study.
Pressure to work as hard as adults takes a toll
A smaller New York University study published in 2015 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.
