I’m a teacher in a uk school and I really struggle with the continuous bad behaviour in my classes. The students are so naughty for me. I have been on many behaviour courses I’ve tried strict discipline and punishments, I’ve tried seating plans I’ve tried calling parents in, the behaviour is completely unacceptable. I try to be strict and firm with my classes but it still doesn’t work. Does anyone have any advice on dealing with extreme behavioural problems in high school students?
