average amount of homework for students

• Countries Who Spend the Most Time Doing Homework

Homework is an important aspect of the education system and is often dreaded by the majority of students all over the world. Although many teachers and educational scholars believe homework improves education performance, many critics and students disagree and believe there is no correlation between homework and improving test scores.

The Organization for Economic Cooperation and Development (OECD) is an intergovernmental organization. With headquarters in Paris, the organization was formed for the purpose of stimulating global trade and economic progress among member states. In 2009, the OECD conducted a detailed study to establish the number of hours allocated for doing homework by students around the world and conducted the research in 38 member countries. The test subjects for the study were 15 year old high school students in countries that used PISA exams in their education systems. The results showed that in Shanghai, China the students had the highest number of hours of homework with 13.8 hours per week. Russia followed, where students had an average of 9.7 hours of homework per week. Finland had the least amount of homework hours with 2.8 hours per week, followed closely by South Korea with 2.9 hours. Among all the countries tested, the average homework time was 4.9 hours per week.

Interpretation of the data

Although students from Finland spent the least amount of hours on their homework per week, they performed relatively well on tests which discredits the notion of correlation between the number of hours spent on homework with exam performance. Shanghai teenagers who spent the highest number of hours doing their homework also produced excellent performances in the school tests, while students from some regions such as Macao, Japan, and Singapore increased the score by 17 points per additional hour of homework. The data showed a close relation between the economic backgrounds of students and the number of hours they invested in their homework. Students from affluent backgrounds spent fewer hours doing homework when compared to their less privileged counterparts, most likely due to access to private tutors and homeschooling. In some countries such as Singapore, students from wealthy families invested more time doing their homework than less privileged students and received better results in exams.

Decline in number of hours

Subsequent studies conducted by the OECD in 2012 showed a decrease in the average number hours per week spent by students. Slovakia displayed a drop of four hours per week while Russia declined three hours per week. A few countries including the United States showed no change. The dramatic decline of hours spent doing homework has been attributed to teenager’s increased use of the internet and social media platforms.

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 Much Homework Is Enough? Depends Who You Ask

• Share article

Editor’s note: This is an adapted excerpt from You, Your Child, and School: Navigate Your Way to the Best Education ( Viking)—the latest book by author and speaker Sir Ken Robinson (co-authored with Lou Aronica), published in March. For years, Robinson has been known for his radical work on rekindling creativity and passion in schools, including three bestselling books (also with Aronica) on the topic. His TED Talk “Do Schools Kill Creativity?” holds the record for the most-viewed TED talk of all time, with more than 50 million views. While Robinson’s latest book is geared toward parents, it also offers educators a window into the kinds of education concerns parents have for their children, including on the quality and quantity of homework.

The amount of homework young people are given varies a lot from school to school and from grade to grade. In some schools and grades, children have no homework at all. In others, they may have 18 hours or more of homework every week. In the United States, the accepted guideline, which is supported by both the National Education Association and the National Parent Teacher Association, is the 10-minute rule: Children should have no more than 10 minutes of homework each day for each grade reached. In 1st grade, children should have 10 minutes of daily homework; in 2nd grade, 20 minutes; and so on to the 12th grade, when on average they should have 120 minutes of homework each day, which is about 10 hours a week. It doesn’t always work out that way.

In 2013, the University of Phoenix College of Education commissioned a survey of how much homework teachers typically give their students. From kindergarten to 5th grade, it was just under three hours per week; from 6th to 8th grade, it was 3.2 hours; and from 9th to 12th grade, it was 3.5 hours.

There are two points to note. First, these are the amounts given by individual teachers. To estimate the total time children are expected to spend on homework, you need to multiply these hours by the number of teachers they work with. High school students who work with five teachers in different curriculum areas may find themselves with 17.5 hours or more of homework a week, which is the equivalent of a part-time job. The other factor is that these are teachers’ estimates of the time that homework should take. The time that individual children spend on it will be more or less than that, according to their abilities and interests. One child may casually dash off a piece of homework in half the time that another will spend laboring through in a cold sweat.

Do students have more homework these days than previous generations? Given all the variables, it’s difficult to say. Some studies suggest they do. In 2007, a study from the National Center for Education Statistics found that, on average, high school students spent around seven hours a week on homework. A similar study in 1994 put the average at less than five hours a week. Mind you, I [Robinson] was in high school in England in the 1960s and spent a lot more time than that—though maybe that was to do with my own ability. One way of judging this is to look at how much homework your own children are given and compare it to what you had at the same age.

Many parents find it difficult to help their children with subjects they’ve not studied themselves for a long time, if at all.

There’s also much debate about the value of homework. Supporters argue that it benefits children, teachers, and parents in several ways:

• Children learn to deepen their understanding of specific content, to cover content at their own pace, to become more independent learners, to develop problem-solving and time-management skills, and to relate what they learn in school to outside activities.
• Teachers can see how well their students understand the lessons; evaluate students’ individual progress, strengths, and weaknesses; and cover more content in class.
• Parents can engage practically in their children’s education, see firsthand what their children are being taught in school, and understand more clearly how they’re getting on—what they find easy and what they struggle with in school.

Q&A With Sir Ken Robinson

Ashley Norris is assistant dean at the University of Phoenix College of Education. Commenting on her university’s survey, she says, “Homework helps build confidence, responsibility, and problem-solving skills that can set students up for success in high school, college, and in the workplace.”

That may be so, but many parents find it difficult to help their children with subjects they’ve not studied themselves for a long time, if at all. Families have busy lives, and it can be hard for parents to find time to help with homework alongside everything else they have to cope with. Norris is convinced it’s worth the effort, especially, she says, because in many schools, the nature of homework is changing. One influence is the growing popularity of the so-called flipped classroom.

In the stereotypical classroom, the teacher spends time in class presenting material to the students. Their homework consists of assignments based on that material. In the flipped classroom, the teacher provides the students with presentational materials—videos, slides, lecture notes—which the students review at home and then bring questions and ideas to school where they work on them collaboratively with the teacher and other students. As Norris notes, in this approach, homework extends the boundaries of the classroom and reframes how time in school can be used more productively, allowing students to “collaborate on learning, learn from each other, maybe critique [each other’s work], and share those experiences.”

Even so, many parents and educators are increasingly concerned that homework, in whatever form it takes, is a bridge too far in the pressured lives of children and their families. It takes away from essential time for their children to relax and unwind after school, to play, to be young, and to be together as a family. On top of that, the benefits of homework are often asserted, but they’re not consistent, and they’re certainly not guaranteed.

What’s the Right Amount of Homework?

Decades of research show that homework has some benefits, especially for students in middle and high school—but there are risks to assigning too much.

Your content has been saved!

Many teachers and parents believe that homework helps students build study skills and review concepts learned in class. Others see homework as disruptive and unnecessary, leading to burnout and turning kids off to school. Decades of research show that the issue is more nuanced and complex than most people think: Homework is beneficial, but only to a degree. Students in high school gain the most, while younger kids benefit much less.

The National PTA and the National Education Association support the “ 10-minute homework guideline ”—a nightly 10 minutes of homework per grade level. But many teachers and parents are quick to point out that what matters is the quality of the homework assigned and how well it meets students’ needs, not the amount of time spent on it.

The guideline doesn’t account for students who may need to spend more—or less—time on assignments. In class, teachers can make adjustments to support struggling students, but at home, an assignment that takes one student 30 minutes to complete may take another twice as much time—often for reasons beyond their control. And homework can widen the achievement gap, putting students from low-income households and students with learning disabilities at a disadvantage.

However, the 10-minute guideline is useful in setting a limit: When kids spend too much time on homework, there are real consequences to consider.

Small Benefits for Elementary Students

As young children begin school, the focus should be on cultivating a love of learning, and assigning too much homework can undermine that goal. And young students often don’t have the study skills to benefit fully from homework, so it may be a poor use of time (Cooper, 1989 ; Cooper et al., 2006 ; Marzano & Pickering, 2007 ). A more effective activity may be nightly reading, especially if parents are involved. The benefits of reading are clear: If students aren’t proficient readers by the end of third grade, they’re less likely to succeed academically and graduate from high school (Fiester, 2013 ).

For second-grade teacher Jacqueline Fiorentino, the minor benefits of homework did not outweigh the potential drawback of turning young children against school at an early age, so she experimented with dropping mandatory homework. “Something surprising happened: They started doing more work at home,” Fiorentino writes . “This inspiring group of 8-year-olds used their newfound free time to explore subjects and topics of interest to them.” She encouraged her students to read at home and offered optional homework to extend classroom lessons and help them review material.

Moderate Benefits for Middle School Students

As students mature and develop the study skills necessary to delve deeply into a topic—and to retain what they learn—they also benefit more from homework. Nightly assignments can help prepare them for scholarly work, and research shows that homework can have moderate benefits for middle school students (Cooper et al., 2006 ). Recent research also shows that online math homework, which can be designed to adapt to students’ levels of understanding, can significantly boost test scores (Roschelle et al., 2016 ).

There are risks to assigning too much, however: A 2015 study found that when middle school students were assigned more than 90 to 100 minutes of daily homework, their math and science test scores began to decline (Fernández-Alonso, Suárez-Álvarez, & Muñiz, 2015 ). Crossing that upper limit can drain student motivation and focus. The researchers recommend that “homework should present a certain level of challenge or difficulty, without being so challenging that it discourages effort.” Teachers should avoid low-effort, repetitive assignments, and assign homework “with the aim of instilling work habits and promoting autonomous, self-directed learning.”

In other words, it’s the quality of homework that matters, not the quantity. Brian Sztabnik, a veteran middle and high school English teacher, suggests that teachers take a step back and ask themselves these five questions :

• How long will it take to complete?
• Have all learners been considered?
• Will an assignment encourage future success?
• Will an assignment place material in a context the classroom cannot?
• Does an assignment offer support when a teacher is not there?

More Benefits for High School Students, but Risks as Well

By the time they reach high school, students should be well on their way to becoming independent learners, so homework does provide a boost to learning at this age, as long as it isn’t overwhelming (Cooper et al., 2006 ; Marzano & Pickering, 2007 ). When students spend too much time on homework—more than two hours each night—it takes up valuable time to rest and spend time with family and friends. A 2013 study found that high school students can experience serious mental and physical health problems, from higher stress levels to sleep deprivation, when assigned too much homework (Galloway, Conner, & Pope, 2013 ).

Homework in high school should always relate to the lesson and be doable without any assistance, and feedback should be clear and explicit.

Teachers should also keep in mind that not all students have equal opportunities to finish their homework at home, so incomplete homework may not be a true reflection of their learning—it may be more a result of issues they face outside of school. They may be hindered by issues such as lack of a quiet space at home, resources such as a computer or broadband connectivity, or parental support (OECD, 2014 ). In such cases, giving low homework scores may be unfair.

Since the quantities of time discussed here are totals, teachers in middle and high school should be aware of how much homework other teachers are assigning. It may seem reasonable to assign 30 minutes of daily homework, but across six subjects, that’s three hours—far above a reasonable amount even for a high school senior. Psychologist Maurice Elias sees this as a common mistake: Individual teachers create homework policies that in aggregate can overwhelm students. He suggests that teachers work together to develop a school-wide homework policy and make it a key topic of back-to-school night and the first parent-teacher conferences of the school year.

Parents Play a Key Role

Homework can be a powerful tool to help parents become more involved in their child’s learning (Walker et al., 2004 ). It can provide insights into a child’s strengths and interests, and can also encourage conversations about a child’s life at school. If a parent has positive attitudes toward homework, their children are more likely to share those same values, promoting academic success.

But it’s also possible for parents to be overbearing, putting too much emphasis on test scores or grades, which can be disruptive for children (Madjar, Shklar, & Moshe, 2015 ). Parents should avoid being overly intrusive or controlling—students report feeling less motivated to learn when they don’t have enough space and autonomy to do their homework (Orkin, May, & Wolf, 2017 ; Patall, Cooper, & Robinson, 2008 ; Silinskas & Kikas, 2017 ). So while homework can encourage parents to be more involved with their kids, it’s important to not make it a source of conflict.
