Back in the day ... the punishment was being strapped. The strap was maybe 16" x 4" and looked like it was from a piece of conveyor belting. Typically five on each outstretched hand ... hurt like hell. Speaking from personal experience.
Back in my day they sent you home. Fine with us in high school. We did not want kids like this in the classroom, and I mean other kids did not want kids like this. I even complained once to the school counselor about how one boy was misbehaving. I told her the teacher would call him down but he still was bad. I wanted to learn and he was keeping me from hearing what the teacher had to say. If he wanted to be retarded (no offense to those with Trisomy 21) then send him home, and let the rest of us learn.
