Gray Matters: What role should homework play in learning?
Historical Background In the U.S., debates about the value of homework have been steady over the past century. In the beginning half of the 1900’s, homework was not nearly as common. Many school districts banned homework at the elementary and middle school levels in the belief that it only facilitated rote learning. That changed in the 1950’s when the Soviet Union launched Sputnik, creating the perception that the U.S. needed to increase the amount of students’ homework to be competitive in the space race. Over the next 50 years until the present, the popular view of homework switched every 15 years or so between support and condemnation. Today research has enhanced our understanding, but the debate continues.
Homework: What’s the Point? Numerous benefits are attributed to homework: better retention of factual knowledge, development of study habits, increased ability to manage time effectively, and heightened parental involvement. Evaluating exactly what of these benefits can be attributed to homework versus inherent differences in students or the quality of assignments presents obvious challenges. Further confounding research, homework often exacts costs in the form of increased stress and reduced sleep, which can negate potential benefits. Nonetheless, research to date provides guidance on homework’s role in achieving some of these goals.
Research Examples How much homework should be assigned? Although not unanimous, multiple studies on the relationship between homework time and academic achievement have shown that it is not a linear relationship: more homework does not equal more learning. One study of 7,451 13- year-old students administered a test of science and mathematics in addition to a survey of effort spent on homework, homework time, homework frequency, and the general circumstances around how homework was done. Results: student academic gains were associated with homework time up to 1 hour a day, after which increased homework time was associated with worse performance. This result varies with students’ ages.
How does the influence of homework change in different grades? While empirical studies have not yet explicitly compared the role of homework in different ages, a review of the literature reveals clear trends. A meta-analysis of 4,400 studies up until 2003 found that homework time had different effects depending on the grade of students. Results: up to two hours of homework showed the most benefit for high school students, up to an hour of homework showed some benefit for middle school students, and almost no benefit was found among elementary school students.
What homework factors contribute to academic performance? Studies that focus on the circumstances in which students complete homework have found that autonomy and effort are more important predictors of performance than homework time alone. One study of 483 eighth-graders from 20 classes analyzed students’ grades and standardized test scores in mathematics in relation to survey responses on homework effort. Students responded once in November and once in May of the academic year. Results: academic gains in grades and test scores were positively correlated to homework effort. However, other studies suggest that since effort and autonomy are highly correlated with students’ prior achievement, it’s difficult to say if this is a trait of the homework or of a certain kind of student.
How can homework best facilitate learning? Practices from the “ How can I improve longterm learning ” edition of Gray Matters 01 should be implemented in homework design to facilitate learning. For instance, using homework to continue practice on material and skills learned in previous weeks uses distributed practice to improve recall. Homework that offers adequate practice of important skills also helps reinforce skills in a variety of contexts. A survey of school leaders around homework best practices found similar results: homework can facilitate engagement when it is an authentic, engaging extension of the class. Results: homework should be designed intentionally, with reference to most effective forms of practice.
Does the effect of homework change when instruction occurs at home and exercises are done in class? In this case, the question is essentially if homework facilitates learning when it is done as a part class rather than at home. One model that represents this circumstance is the flipped classroom. Case studies done with ninth to twelfth-graders across a variety of subjects showed that achievement increased after implementing a model where students watched videos at home and practiced learning in class. In these schools the percentage of students passing standardized exams increased by up to 12%. Empirical studies comparing in-class work and at home work have repeated research design flaws, however, they generally indicate that in-class exercises have a positive effect for older students. Results: the research is inconclusive, but generally indicates that flipped classroom approaches have positive net benefits for high school students.
How frequently should homework be assigned? The research on frequency is not conclusive, however most studies suggest that classes that receive homework frequently tend to do better on tests of achievement. One such study administered standardized mathematics examinations to 2,939 grade 7 and 8 students across 20 classes. In addition to the exam, students answered questions on frequency of homework and the average amount of time spent on homework each evening. Results: Classes that had more frequent homework assignments had overall higher averages on the achievement tests.
Does homework change students’ attitudes towards school? Studies comparing the attitudes of students who received homework with those who did not receive homework generally found no significant results across a variety of grade levels. One study compared three different models for assigning arithmetic homework to 342 third-graders across twelve classrooms: teachers assigned no homework, assigned homework as usual, and were required to assign a constant amount of homework every night. Students answered questions measuring their attitudes towards school, teacher, arithmetic, spelling, reading, and homework. Results: no significant differences were found between the attitudes of the different groups.
Conclusion The quality of homework and the students who complete it vary significantly, however the general research trends suggest that assigning homework does have benefits at the middle and upper school levels. Frequency of assignment and students’ autonomy in finishing homework were also correlated with student achievement. These results provide guidelines on the appropriate quantity of homework, but how best to incorporate homework content into an overall progression of students’ learning remains for teachers to judge.

Does homework still have value? A Johns Hopkins education expert weighs in
Joyce epstein, co-director of the center on school, family, and community partnerships, discusses why homework is essential, how to maximize its benefit to learners, and what the 'no-homework' approach gets wrong.
By Vicky Hallett
The necessity of homework has been a subject of debate since at least as far back as the 1890s, according to Joyce L. Epstein , co-director of the Center on School, Family, and Community Partnerships at Johns Hopkins University. "It's always been the case that parents, kids—and sometimes teachers, too—wonder if this is just busy work," Epstein says.
But after decades of researching how to improve schools, the professor in the Johns Hopkins School of Education remains certain that homework is essential—as long as the teachers have done their homework, too. The National Network of Partnership Schools , which she founded in 1995 to advise schools and districts on ways to improve comprehensive programs of family engagement, has developed hundreds of improved homework ideas through its Teachers Involve Parents in Schoolwork program. For an English class, a student might interview a parent on popular hairstyles from their youth and write about the differences between then and now. Or for science class, a family could identify forms of matter over the dinner table, labeling foods as liquids or solids. These innovative and interactive assignments not only reinforce concepts from the classroom but also foster creativity, spark discussions, and boost student motivation.
"We're not trying to eliminate homework procedures, but expand and enrich them," says Epstein, who is packing this research into a forthcoming book on the purposes and designs of homework. In the meantime, the Hub couldn't wait to ask her some questions:
What kind of homework training do teachers typically get?
Future teachers and administrators really have little formal training on how to design homework before they assign it. This means that most just repeat what their teachers did, or they follow textbook suggestions at the end of units. For example, future teachers are well prepared to teach reading and literacy skills at each grade level, and they continue to learn to improve their teaching of reading in ongoing in-service education. By contrast, most receive little or no training on the purposes and designs of homework in reading or other subjects. It is really important for future teachers to receive systematic training to understand that they have the power, opportunity, and obligation to design homework with a purpose.
Why do students need more interactive homework?
If homework assignments are always the same—10 math problems, six sentences with spelling words—homework can get boring and some kids just stop doing their assignments, especially in the middle and high school years. When we've asked teachers what's the best homework you've ever had or designed, invariably we hear examples of talking with a parent or grandparent or peer to share ideas. To be clear, parents should never be asked to "teach" seventh grade science or any other subject. Rather, teachers set up the homework assignments so that the student is in charge. It's always the student's homework. But a good activity can engage parents in a fun, collaborative way. Our data show that with "good" assignments, more kids finish their work, more kids interact with a family partner, and more parents say, "I learned what's happening in the curriculum." It all works around what the youngsters are learning.
Is family engagement really that important?
At Hopkins, I am part of the Center for Social Organization of Schools , a research center that studies how to improve many aspects of education to help all students do their best in school. One thing my colleagues and I realized was that we needed to look deeply into family and community engagement. There were so few references to this topic when we started that we had to build the field of study. When children go to school, their families "attend" with them whether a teacher can "see" the parents or not. So, family engagement is ever-present in the life of a school.
My daughter's elementary school doesn't assign homework until third grade. What's your take on "no homework" policies?
There are some parents, writers, and commentators who have argued against homework, especially for very young children. They suggest that children should have time to play after school. This, of course is true, but many kindergarten kids are excited to have homework like their older siblings. If they give homework, most teachers of young children make assignments very short—often following an informal rule of 10 minutes per grade level. "No homework" does not guarantee that all students will spend their free time in productive and imaginative play.
Some researchers and critics have consistently misinterpreted research findings. They have argued that homework should be assigned only at the high school level where data point to a strong connection of doing assignments with higher student achievement . However, as we discussed, some students stop doing homework. This leads, statistically, to results showing that doing homework or spending more minutes on homework is linked to higher student achievement. If slow or struggling students are not doing their assignments, they contribute to—or cause—this "result."
Teachers need to design homework that even struggling students want to do because it is interesting. Just about all students at any age level react positively to good assignments and will tell you so.
Did COVID change how schools and parents view homework?
Within 24 hours of the day school doors closed in March 2020, just about every school and district in the country figured out that teachers had to talk to and work with students' parents. This was not the same as homeschooling—teachers were still working hard to provide daily lessons. But if a child was learning at home in the living room, parents were more aware of what they were doing in school. One of the silver linings of COVID was that teachers reported that they gained a better understanding of their students' families. We collected wonderfully creative examples of activities from members of the National Network of Partnership Schools. I'm thinking of one art activity where every child talked with a parent about something that made their family unique. Then they drew their finding on a snowflake and returned it to share in class. In math, students talked with a parent about something the family liked so much that they could represent it 100 times. Conversations about schoolwork at home was the point.
How did you create so many homework activities via the Teachers Involve Parents in Schoolwork program?
We had several projects with educators to help them design interactive assignments, not just "do the next three examples on page 38." Teachers worked in teams to create TIPS activities, and then we turned their work into a standard TIPS format in math, reading/language arts, and science for grades K-8. Any teacher can use or adapt our prototypes to match their curricula.
Overall, we know that if future teachers and practicing educators were prepared to design homework assignments to meet specific purposes—including but not limited to interactive activities—more students would benefit from the important experience of doing their homework. And more parents would, indeed, be partners in education.
