My granddad was telling me about his school the other day. It was very strict, and if they didn't wear a uniform they had to go home and change their clothes. Students got detention for things like not sitting properly in class. He said he often had to shouting, usually 'I must not talk in class'. There were physical punishments, too, if you didn't arrive on time for school, or cheat in an exam. Even if a teacher heard you getting, you had to go and see the principal. He also said there was a lot of shouting but no-one told the teachers. What about rewards? I asked. He said the students who always handed in marks day and got good the next in their exams sometimes got a boring book at the end of the year. His school was very different from ours!
