My class is on the whole, well behaved - when in the classroom. They respond to praise and the various sanctions. The problem I'm having now, is that within the last few weeks, certain individuals from the class have been 'playing up' other teachers/members of staff outside the classroom and around the school, for example in the dining hall they're answering back and being rude. Why can't they be 'good' for everyone else and not just for me? Does anyone have any strategies because my class is getting a reputation due to the few miscreants. I somehow feel it's my fault and my responsibility. Is it? I wasn't aware of any problems until recently. At the moment, I'm being moaned at about certain individuals on a regular basis. please help. Thank you.
