I'm 3 weeks into a new job as an NQT, and am having problems with a couple of Y8 classes. I am unable to get on with the planned lesson because of continious low level disruption - the classes are just too chatty. Each lesson I give them several opportunities, but I rarely get through my starter - as a result, for the last three lessons they have ended up silently answering questions from a textbook. Last lesson I told them if they could do five solid minutes working in silence, then we could continue with the proper lesson. They did so we tried to start again, but they wouldn't shut up, so ended up back with the textbooks. I have been using the textbooks as a punishment, but I'm not convinced that it's effective, and some of the more disruptive students prefer this to doing 'proper' lessons. I have put them in an A-Z seating plan, made a fuss, shouted and waited for long periods of time. I have brought some and all back for breaktime detentions. It is a large group (30+) so difficult to move individual students in the room, and so many are chatting, it is hard to pinpoint individual students. When do pinpoint them, they seem to like having their name on the board. They are set 2, so perfectly able, and I have been doing the same lessons successfully with another year 8 group (so I know that they are at least reasonably interesting). I'm wondering whether I should keep soldiering on with this method, or can anyone suggest anything else I can try please?
