Corporal != Abuse. I was a teacher. Kids were not turning in homework. I gave out about 15 minutes worth of it because independant practice is important. Most kids would just not do it. So I instituted a 5 push up policy. You did 5 push ups for every day in a row you did not turn it homework. So your third day would have been 15 push ups. It worked great. Only three or so kids per class would skip homework, and few kept up the trend. This lasted a very short time. When administration heard, they shut that shit down fast as it was considered corporal punishment. Students stopped turning in homework for the most part after that.
