I am a not yet qualified teacher working on supply until summer before I begin my probation year next year. For the past 4 weeks I have been working two days a week in a P3/4. I should be sharing the class with the PT however the position has been vacant and the head has been covering the other three days. When I first started I was mainly concerned about planning/teaching as the plans had not been updated for a while and I couldn't make sense of the format, however over the past month I've put in some serious hours clawing stuff together and was beginning to feel like I knew what I was doing(-ish). Cue today. The behaviour has been horrific. Kids coming in to class singing, shouting, walking between desks having full volume conversations. Constant background noise. At least 4 kids per lesson asking what they should be doing after me explaining, modelling, having another child explain etc. There is one boy in the class with real behaviour issues who threw things around the class, ripped displays off the wall and wiped work off the board. Every time I tried to diffuse the situation with him chaos erupted elsewhere. Another (new) pupil was in tears because she misses her old school and another (also new) was caught kicking her partner under the table. Every time I come in it seems the head has implemented a new behaviour strategy and none of them have been explained to me. There is a traffic light and personal points display on the wall - neither of the new pupils are on this and it's being used totally inconsistently. Personally, I hate traffic light behaviour management but I don't know if this is the time of year to take it down. I'm the 5th teacher they've had this year and clearly there is no consistency. Plus me being totally inexperienced means I don't know how to fix this situation. Since getting home this evening I've done some googling and come up with this advice - http://www.smartclassroommanagement...you-realize-youve-lost-control-of-your-class/ Experienced teachers here, can you please weigh in?
