Homework is a key factor in education because it can help us to better understand the work we are doing. Doing homework everyday, or even just a few days a week, is good practice on any information we are learning in school. The more we do it and practice it, the better we will be at it.
Homework helps to reinforce learning and develop good study habits and life skills. Everyone knows that practice makes perfect. Students typically retain only 50% of the information teachers provide in class, and they need to apply that information in order to truly learn it.
