I dont know how useful these would be, but heres some of the things I've tried: Boy-girl seating plans (its actually school policy for KS3). Giving each pupil a post-it at the beginning of the lesson, and getting them to write their ideas/thoughts/questions on them. At the end as them to pick one of their ideas/thoughs/questions to share with the class. Instead of shouting, just give them a look, hold eye contact for a few seconds and carry on. Stand by the door of the class, looking at your watch. Its amazing how one person will look and it spreads like wild fire! Hope all these helps. Lexi.
