I have a year 9 class, who have recently been changed round and streamed, so people have left the class, and some have come into the class. I have a real problem with one or two of them in this class. One particularly disruptive pupil, who is always on report, and is insolent and tends to be the bad apple in the class. He has been excluded once or twice from my class, and spent time with HOY, but always comes back unfortunately. I have changed the seat plan, issued detentions, but he and a few other pupils who disrupt the lesson and make it unpleasant for the good ones, just continue to make things difficult in class. One of the new pupils to the class has told their parent, who has told the head of year, that it is disruptive and she cant work, and she wants to move classes. its also a co-incidence she has move from a higher ability class to this lower ability class (could be some sour grapes). After this complaint I have looked at her work, and she seems to be doing very little at all, whereas I know some of the good kids are completing their work as I ask them. I am wondering if any one has any advice, i.e. how to handle her, how to handle the bad behaviour, I am at a bit of a loss, and a bit embarrased to be honest, so any help would be appreciated.
