I'm in my second placement at the moment. I didn't need much behaviour management in my first, the little things like standing quietly and looking stern/bored/disappointed, or standing behind individuals always did the trick when gaining control. But now I'm in a tougher school and there's one particular GCSE Yr 9 group that I just can't control. They kind-of settle outside, then start chatting as they come in and sit down. I can't get them quiet, despite them supposed to be writing the objective and doing a little starter task that is always up ready for them. Shushing doesn't work. Asking for quiet doesn't work. Demanding silence for the register worked today until the end of the register when it all started off again. If they're not chatting, they're shouting out answers when I'm insisting on hands up. Today I completely lost face as I (disastrously) put them all on a warning and said that if I had to ask anyone to stop talking, I'd time-out them to another class (the first stage before a detention). Once threatened, I know I had to go through with it so 8 were sent out, some complaining they were talking about the work. This was obviously way too many, made it a bit of a game for them and I looked faintly ridiculous. I threatened them with being kept behind for 10 minutes, but this also penalises the good ones. And for this reason I also don't really want to do the timer that I count up when I want quiet and hold them back for that length of time after school. This was all during the initial set-up of the lesson, talking about the starter where they'd had to come up with a few suggestions. I think part of it is that I'm on a losing battle against the prevailing culture of doing very little work at the school. But I really shouldn't be failing at the first hurdle of getting some quiet! How can I get this group to shut up? What sanction can I use that target the bad ones, leaves the good ones alone and doesn't make me look an idiot if half the class are on it? Because at the moment, for the first time, I want to jack it in and possibly go down for murder.
