Hello, I am a new teacher in a good comprehensive school. Although the behaviour in my school can be tough, I love where I work and I have managed to turn really difficult classes around so that even the notorious girls in them work with me most of the time and are making progress. However, I have a particularly difficult, KS3 shared class. I share this class with the same teacher who taught them since they came to the school. They are perfectly behaved for their other teacher, but seem to use my lessons with them as an excuse to mess around and do whatever they please. This class has quite a few difficult children in it and they seem to pack together to make it almost impossible for me to teach them. They are very rude, do not take my detentions or phonecalls home seriously and they always talk over me and do not stay focused on their learning. I am planning lessons for them that are fun and I get these looked at every week by my HOD and the teacher I share the class with before I teach them to make sure they are pitched appropriately and that they are enjoyable. Despite trying every strategy I can think of and have read about in books/internet and from teacher friends, getting other members of staff in to help and being really firm with the girls, they still do not pull together to focus on the learning. It is making it horrendous to teach them and I feel totally powerless when I am in the classroom with them. Worse still, for the whole year the girls have been dragging their total lack of respect for me into the corridors, mimicking my accent and making rude comments. Although I have reported this to their HOY on several occasions, nothing has changed. Their progress is really being affected, not that they seem to mind about this, and the good girls are really suffering for it: in the class though, it seems there are only about 5 good girls and the rest want to talk, argue, be rude and generally do whatever they want with no care at all for the sanctions even though I always follow up what I say I am going to do. I have tried everything with this class and I don't know what to do next. Recently a girl who is notoriously poorly behaved was moved out of another set and into mine too because her poor behaviour in the other set was causing so many issues. This has only made things with this class so much worse. Does anyone have any tips on how to turn this round? What do I do with the class if it can't be sorted out? Thanks in advance for your help!
