I remember when I was in 7th grade and we were first introduced to the Saxon math books. We would learn new material, but our homework constantly reinforced information from previous sections so that we never needed to go back to study anything, because we were solving the older problems on a daily basis and could be expected to solve them on tests.

Requiring that students not only show that they understand current knowledge but also that they retain past knowledge seems to be a much better way to educate students. It obliterates the slacker cram mentality that many students have.
