I love anything that I feel will make me a better teacher. Behaviour management is one area that I will constantly be aiming to be the best that I can be. I recently did a 3 day work-shop called 1-2-3 Magic® & Emotion Coaching which I found extremely beneficial and will definitely be using some of the strategies I learnt in future classrooms. Here are a couple of web sites that I have also found very informative.
One of my all time favourites
I will add to this if I find other links
