Homework, or a homework assignment, is a set of tasks assigned to "students by their "teachers to be completed outside the "class. Common homework assignments may include a quantity or period of "reading to be performed, "writing or "typing to be completed, math problems to be solved, material to be reviewed before a "test, or other skills to be practiced.
The effect of homework is debated. Generally speaking, homework does not improve academic performance among children and may improve academic skills among older students. It also creates stress for students and their parents and reduces the amount of time that students could spend outdoors, exercising, playing sports, working, sleeping or in other activities.
The basic objectives of assigning homework to students are the same as schooling in general: to increase the knowledge and improve the abilities and skills of the students, to prepare them for upcoming (or complex or difficult) lessons, to extend what they know by having them apply it to new situations, or to integrate their abilities by applying different skills to a single task. Homework also provides an opportunity for parents to participate in their children's education. Homework also may be designed to reinforce what students have already learned.
Teachers have many purposes for assigning homework including:
Homework research dates back to the early 1900s. However, no consensus exists on the general effectiveness on homework. Results of homework studies vary based on multiple factors, such as the age group of those studied and the measure of academic performance.
Among teenagers, students who spend somewhat more time on homework generally have higher "grades and somewhat higher test scores than students who spend less time on homework. Very high amounts of homework cause students' academic performance to worsen, even among older students. Students who are assigned homework in middle and high school score somewhat better on standardized tests, but that students who have 60 to 90 minutes of homework a day in middle school or more than 2 hours in high school score worse.
However, younger students who spend more time on homework generally have slightly worse or the same academic performance than those who spend less time on homework. Homework does not improve academic achievements for "grade school students.
Low-achieving students receive more benefit from doing homework than high-achieving students. However, schoolteachers commonly assign less homework to the students who need it most, and more homework to the students who are performing well.
The amount of homework given does not necessarily affect students' attitudes towards homework and various other aspects of school.
Epstein (1988) found a near-zero correlation between the amount of homework and parents' reports on how well their elementary school students behaved. Vazsonyi & Pickering (2003) studied 809 adolescents in American high schools, and found that, using the Normative Deviance Scale as a model for "deviance, the correlation was r = .28 for Caucasian students, and r = .24 for African-American students. For all three of the correlations, higher values represent a higher correlation between time spent on homework and poor conduct.
Bempechat (2004) says that homework develops students' motivation and study skills. In a single study, parents and teachers of middle school students believed that homework improved students' study skills and personal responsibility skills. Their students were more likely to have negative perceptions about homework and were less likely to ascribe the development of such skills to homework. Leone & Richards (1989) found that students generally had negative emotions when completing homework and reduced engagement compared to other activities.
Homework has been identified in numerous studies and articles as a dominant or significant source of stress and anxiety for students. Studies on the relation between homework and health are few compared to studies on academic performance.
Cheung & Leung-Ngai (1992) surveyed 1,983 students in Hong Kong, and found that homework led not only to added stress and anxiety, but also physical symptoms, such as headaches and stomachaches. Students in the survey who were ridiculed or punished by parents and peers had a higher incidence of "depression symptoms, with 2.2% of students reporting that they "always" had suicidal thoughts, and anxiety was exacerbated by punishments and criticism of students by teachers for both problems with homework as well as forgetting to hand in homework.
A 2007 study of American students by "MetLife found that 89% of students felt stressed from homework, with 34% reporting that they "often" or "very often" felt stressed from homework. Stress was especially evident among high school students. Students that reported stress from homework were more likely to be deprived of sleep.
Homework can cause tension and conflict in the home as well as at school, and can reduce students' family and leisure time. In the Cheung & Leung-Ngai (1992) survey, failure to complete homework and low grades where homework was a contributing factor was correlated with greater conflict; some students have reported teachers and parents frequently criticizing their work. In the MetLife study, high school students reported spending more time completing homework than performing home tasks. Kohn (2006) argued that homework can create family conflict and reduce students' quality of life. The authors of Sallee & Rigler (2008), both high school English teachers, reported that their homework disrupted their students' extracurricular activities and responsibilities. However, Kiewra et al. (2009) found that parents were less likely to report homework as a distraction from their children's activities and responsibilities. Galloway, Conner & Pope (2013) recommended further empirical study relating to this aspect due to the difference between student and parent observations.
Galloway, Conner & Pope (2013) surveyed 4,317 high school students from ten high-performing schools, and found that students reported spending more than 3 hours on homework daily. 72% of the students reported stress from homework, and 82% reported physical symptoms. The students slept an average of 6 hours 48 minutes, lower than the recommendations prescribed by various health agencies.
A study done at the "University of Michigan in 2007 concluded that the amount of homework given is increasing. In a sample taken of students between the ages of 6 and 9 years, it was shown that students spend more than 2 hours a week on homework, as opposed to 44 minutes in 1981.

Historically, homework was frowned upon in "American culture. With few students interested in "higher education, and due to the necessity to complete daily chores, homework was discouraged not only by parents, but also by school districts. In 1901, the "California legislature passed an act that effectively abolished homework for those who attended kindergarten through the eighth grade. But, in the 1950s, with increasing pressure on the United States to stay ahead in the "Cold War, homework made a resurgence, and children were encouraged to keep up with their "Russian counterparts. By the end of the Cold War in the early 1990s, the consensus in American education was overwhelmingly in favor of issuing homework to students of all grade levels.
