One of my favorite teachers in high school had the following policies: * There will be a short quiz every week covering recent material. * Homework is optional for any student who got an A on the last quiz (due to the length of the quizzes, that essentially meant 100%). * Anyone with an A average in the class so far and an A on the last quiz is permitted to sleep in class. It worked great. Nobody's time was being wasted on busy work, nor were people recklessly left behind.
