There is no conclusive evidence that homework increases student achievement across the board. Some studies show positive effects of homework under certain conditions and for certain students, some show no effects, and some suggest negative effects (Kohn 2006; Trautwein and Koller 2003).
Some studies have shown that older students gain more academic benefits from homework than do younger students, perhaps because younger students have less-effective study habits and are more easily distracted (Cooper 1989; Hoover-Dempsey et al. 2001; Leone and Richards 1989; Muhlenbruck et al. 2000).
the benefits of homework
Some researchers believe that students from higher-income homes have more resources (such as computers) and receive more assistance with homework, while low-income students may have fewer resources and less assistance and are therefore less likely to complete the homework and reap any related benefits (McDermott, Goldmen and Varenne 1984; Scott-Jones 1984).
A national study of the influence of homework on student grades across five ethnic groups found that homework had a stronger impact on Asian American students than on students of other ethnicities (Keith and Benson, 1992).
Certain nonacademic benefits of homework have been shown, especially for younger students. Indeed, some primary-level teachers may assign homework for such benefits, which include learning the importance of responsibility, managing time, developing study habits, and staying with a task until it is completed (Cooper, Robinson and Patall 2006; Corno and Xu 2004; Johnson and Pontius 1989; Warton 2001).
While research on the optimum amount of time students should spend on homework is limited, there are indications that for high school students, 1 to 2 hours per night is optimum. Middle school students appear to benefit from smaller amounts (less than 1 hour per night). When students spend more time than this on homework, the positive relationship with student achievement diminishes (Cooper, Robinson, and Patall 2006).
Some research has shown that students who spend more time on homework score higher on measures of achievement and attitude. Studies that have delved more deeply into this topic suggest, however, that the amount of homework assigned by teachers is unrelated to student achievement, while the amount of homework actually completed by students is associated with higher achievement (Cooper 2001; Cooper, Lindsay, Nye, and Greathouse 1998).
Studies of after-school programs that provide homework assistance have found few definite links to improved student achievement. Several studies, however, noted improvements in student motivation and work habits, which may indirectly affect achievement (Cosden, Morrison, Albanese, and Macias 2001; James-Burdumy et al. 2005).
Most teachers assign homework to reinforce what was presented in class or to prepare students for new material. Less commonly, homework is assigned to extend student learning to different contexts or to integrate learning by applying multiple skills around a project. Little research exists on the effects of these different kinds of homework on student achievement, leaving policymakers with little evidence on which to base decisions (Cooper 1989; Foyle 1985; Murphy and Decker 1989).

In another of our blog posts, The Case Against Homework, we articulated several points of view against homework as standard practice for teachers. However, a variety of lessons, content-related and beyond, can be taught or reinforced through homework and are worth exploring. Read on!
This analysis found 12 less-authoritative studies that link achievement to time spent on homework, but control for many other factors that could influence the outcome. Finally, the research team identified 35 studies that found a positive correlation between homework and achievement, but only after elementary school. Dr. Cooper concluded that younger students might be less capable of benefiting from homework due to undeveloped study habits or other factors.
It is also a question that has become divisive. Some people feel that homework is an effective way to reinforce the concepts that were learned at school. Others feel like the time that homework demands would be better spent with a meaningful activity that brings the family together.
1. It encourages the discipline of practice. Repeating the same problems over and over can be boring and difficult, but it also reinforces the practice of discipline. To get better at a skill, repetition is often necessary. You get better with each repetition. By having homework completed every night, especially with a difficult subject, the concepts become easier to understand. That gives the student an advantage later on in life when seeking a vocational career.
6. It provides more time to complete the learning process. The time allotted for each area of study in school, especially in K-12, is often limited to 1 hour or less per day. That is not always enough time for students to be able to grasp core concepts of that material. By creating specific homework assignments which address these deficiencies, it becomes possible to counter the effects of the time shortages. That can benefit students greatly over time.
8. It can be treated like any other extracurricular activity. Some families over-extend themselves on extracurricular activities. Students can easily have more than 40 hours per week, from clubs to sports, that fall outside of regular school hours. Homework can be treated as one of these activities, fitting into the schedule where there is extra time. As an added benefit, some homework can even be completed on the way to or from some activities.
2. It encourages a sedentary lifestyle. Long homework assignments require long periods of sitting. A sedentary lifestyle has numerous direct associations with premature death as children age into adults. Obesity levels are already at or near record highs in many communities. Homework may reinforce certain skills and encourage knowledge retention, but it may come at a high price.
3. Not every home is a beneficial environment. There are some homes that are highly invested into their children. Parents may be involved in every stage of homework or there may be access to tutors that can explain difficult concepts. In other homes, there may be little or no education investment into the child. Some parents push the responsibility of teaching off on the teacher and provide no homework support at all.
5. There is no evidence that homework creates improvements. Survey after survey has found that the only thing that homework does is create a negative attitude toward schooling and education in general. Homework is not associated with a higher level of academic achievement on a national scale. It may help some students who struggle with certain subjects, if they have access to a knowledgeable tutor or parent, but on a community level, there is no evidence that shows improvements are gained.
8. Extra time in school does not equate to better grades. Students in the US spend more than 100 hours of extra time in school already compared to high-performing countries around the world, but that has not closed the educational gap between those countries and the United States. In some educational areas, the US is even falling in global rankings despite the extra time that students are spending in school. When it comes to homework or any other form of learning, quality is much more important than quantity.
9. Accurate practice may not be possible. If homework is assigned, there is a reliance on the student, their parents, or their guardians to locate resources that can help them understand the content. Homework is often about practice, but if the core concepts of that information are not understood or inaccurately understood, then the results are the opposite of what is intended. If inaccurate practice is performed, it becomes necessary for the teacher to first correct the issue and then reteach it, which prolongs the learning process.
11. Too much homework is often assigned to students. There is a general agreement that students should be assigned no more than 10 minutes of homework per day, per grade level. That means a first grader should not be assigned more than 10 minutes of homework per night. Yet for the average first grader in US public schools, they come home with 20 minutes of homework and then are asked to complete 20 minutes of reading on top of that. That means some students are completing 4x more homework than recommended every night. 2ff7e9595c
