When I was a freshman and sophomore in HS we had a teacher who routinely threw chalk and erasers at students he thought were just to damned dense and asked to many questions. He was never disciplined as far as I know but moved to another school when I was a junior. This was in the late 1950s.
For me it was the mid-60’s. My English teacher was very accurate in throwing an eraser at my head, she hit without missing every time. That gets your attention! My science teacher had paddles. Any two kids not paying attention would have to go in front of the class, and take turns swatting each other’s behind. And with enough force, otherwise he would make you repeat until satisfied. The school dean was the worst, as he drilled holes in the paddles to reduce wind resistance. Kids have it easy now.
