assigning more homework helps students to get better grade. According to the case study done by Harris Cooper, a professor of psychology and neuroscience at Duke, approximate 77% showed that homework led to positive effects. To illustrate, students who are assigned to do mathematics homework tend to have better grade than those who are not assigned (Cooper, 2006). Consequently, homework is a tool for enhancing student accomplishment. In this case, students will get an opportunity to make a decision by applying their skills. Students can learn from their mistakes and improve on what they are not good at.
