Homework is designed to reinforce what students have already learned.
Students who are assigned homework in middle and high school score somewhat better on standardized tests, but the students who have 60 to 90 minutes of homework a day in middle school or more than two hours in high school score worse.
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.
Common homework assignments may include required reading, a writing or typing project, mathematical exercises to be completed, information to be reviewed before a test, or other skills to be practiced. Generally speaking, homework does not improve academic performance among children and may improve academic skills among older students, especially lower-achieving students.
Homework also creates stress for students and their parents and reduces the amount of time that students could spend outdoors, exercising, playing, working, sleeping, or in other activities.A major study tracking 3,000 students over a 15 year period found that those who spent more than two hours per night on homework got better grades in maths English and science.Any time spent doing homework showed benefits but those who spent two to three hours per night showed greater benefits.A 2007 study of American students by Met Life 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.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 Met Life study, high school students reported spending more time completing homework than performing home tasks.Proponents claim that assigning homework to young children helps them learn good study habits.Essentially, they advocate for doing potentially unnecessary homework from approximately age five to ten as a way of practicing for doing necessary homework from age 10 to 15.Students who need homework help with math and are continuously asking for math homework help should have access to extra support outside of school to ensure that their grades improve throughout the year.Review and practice what they have covered in class; Prepare for class the next day; Learn to use resources, Such as libraries, Reference materials, And Web sites; Explore subjects more fully than classroom time permits; Extend learning by applying skills they already have to new situations; Integrate their learning by applying many different skills to a single task, Such as book reports or science projects; and Learn to manage time and meet deadlines.
