Do today's students have too much homework?

It's all over the news: Kids are spending a lot of time on homework. And, according to some, it's far too much. With the current emphasis on high-stakes testing, educators are trying to do more with less, which can result in an overabundance of schoolwork outside of school. Some critics say there is no evidence to suggest that homework, in and of itself, is helpful to student achievement; on the contrary, too much of it can overwhelm students and cause them to disengage. Others, however, maintain that homework is necessary and helpful, designed so students can practice the concepts taught in class, build good study habits, and reflect on their own learning.
