Having grown up during the 60s and 70s....teachers, coaches, and principals were allowed to give swats to kids with a paddle or strike their open hand with a ruler or yardstick. (It usually took place in front of the class to set an example)
I remember one incident in the 4th grade where me and a girl were talking in the back of the class while our female teacher was talking. The teacher called us both up to the front of the class. She hit the girl in the hand with a yardstick. She then went and got a(male) coach to give me swats. This coach had a paddle with holes drilled in it.
Just because I was a boy she wanted a big man to hit me. He hit me 2 or 3 times but I refused to cry. I thought it was unfair to bring a 3rd party into it.
Although corporal punishment has it's negative side effects on some children I do recall during that era parents, teachers, and school officials (stuck together).There was very little "back talking" by students. We knew who was in charge.
