Hi! I'm now in my fourth year of teaching, but I don't feel that I've got behaviour sorted yet. I spent my first two years in quite a tough, large secondary school where there wasn't really much support from SMT for dealing with poor behaviour and so I didn't make a very good start. I'm now at a small middle school where the SMT are much more supportive. I am endeavouring to follow the behaviour policy to the letter: making my expectations clear, giving warnings and sanctions when these warnings are not heeded, but I am still coming up against lots of low level disruption, which is preventing me from delivering my lessons. I think that a large part of the problem is that I am not assertive enough. I am generally a quiet person, but not necessarily shy. I don't have confidence issues about getting up and speaking in front of a class or doing a presentation in a staff meeting, but I don't particularly go out of my way to make myself the centre of attention in social situations. I have been doing some coaching with an SMT colleague and it has been mentionned that I should try to become more assertive in the classroom to help with behaviour. Do you have any tips regarding this? Something I find difficult is what to actually say to a student when I have kept them back to "tell them off"/ discuss their behaviour. I was a very conscientious child and never got into trouble, so I have no idea what to say, how to say it and what works! Anyway, I fear that I can come across as passive-agressive, or just passive, rather than assertive. What would you suggest? Thanks for reading and apologies for the lack of formatting: my phone won't let me sort it out.
