Developmentally appropriate homework plays a critical role in the formation of positive learning beliefs and behaviors, including a belief in one's academic ability, a deliberative and effortful approach to mastery, and higher expectations and aspirations for one's future.

In short, homework is a key vehicle through which we can help shape children into mature learners. This article describes how homework improves learning and how parents can help.
