Hi Tom, If you have time to help I'd be so grateful. I teach a large class of Y6's. There are a lot of SEN and behavioural issues so I bend over backwards to talk to the children about their interests, build self-esteem wherever I can, and I am meticulous about planning activities that they will find interesting and suitable for their abilities. I must add that on the flipside I follow our behaviour policy to the letter with all the children, and insist they follow our class rules, so I don't feel I come across as a pushover. My problem is that one boy has become so challenging that I feel he can't get through a single lesson or break time without a fight with another pupil, a tantrum, or direct defiance. He seems to enjoy being the victim, and telling me about all the things the other children have said and done to him, but on many ocassions his tales have unravelled as being a pack of lies. No matter how much I recognise good behaviour and talk to him about friendships etc. it just doesn't seem to make a difference.Today was a final straw for me when he started shouting in my face and throwing a chair, two things he has not done before. His mum is supportive in that she will ground him when I tell her about fights etc, but the behaviour is just getting worse and worse (no cause that I can ascertain from mum or the boy in question). My HT always comes back at me with questions as to what I am doing to prevent problems with him, rather than offering any real support, so to be honest I just feel undermined and like there is nowhere to turn on this one - and so it continues. As I said, others in the class are also very challenging, so I really feel like I'm struggling just to cope, let alone actually teach! He is starting to dominate every minute of my day, and is affecting the learning of the others since I spend so long dealing with him (perhaps rewarding him with my attention?). I don't know what I expect you to be able to say, but if you have any other ideas for dealing with behaviour like this, it would be great.
