Teachers Abusing Power

Alyssa asked me how children were punished in school in the past. I recalled vividly that in those days (when I was in pr sch), teachers seemed to have absolute power over the students. Here are some of the abuses I witnessed in primary school:
Teachers tearing our exercise books when they were not pleased with our work;
Teachers throwing exercise books through the window when they were in foul mood, sending the pupils scrambling out of the class room to retrieve them;
Teachers who physically punished students by pinching, slapping, using rulers, brooms etc;
Teachers who humiliate pupils by sweeping their faces using the broom or feather duster, or dust their faces using chalk board duster, or drew whiskers on pupils' faces....
