In some schools what teacher trainers say is true. I went to one of those schools myself, and I did my training in an outstanding school and a good school. And for experienced teachers it is generally true. And yes, a well planned lesson does help. But you can have a well planned all singing all dancing lesson, and a well planned "boring" lesson. As long as the little darlings learn something... It's telling that you say the kids behave when you are being observed... that shows that they think it is only worth behaving if there is somebody to be scared off in the room. You need to become that person. They're testing you, and you're giving them lots of rope. Dya mind if I ask... did you ever not have a member of staff in the room during your PGCE placements? Also, why not wheel out the interactive lessons when you're being observed... then if the kids pick up on it you can smile sweetly and mention something about the right attitude and behaviour for learning. Don't get disheartened, or think that it's a grand conspiracy to trick you. It's not. It's kids acting up, testing boundaries. On the whole they fear change and something new and different, and they are like dogs. They can smell fear. If it makes you feel any better I have to go in on Monday and attempt to kick ass and be a ***, knowing full well that I find it very, very difficult. And the minute they start behaving appropriately I'll revert to being nice again far too soon!
