l squared on "collect and correct"

I teach college, so I feel a little as though I shouldn't have to collect homework...but, of course, I do. If you don't collect it, they don't do it. Collecting the homework may be the single most effective thing I do to improve student learning. I don't check all the problems, just 2-4 representative ones, but it still makes a big difference.
