Hi fellow sufferers! I had an exceptionally awful year 10s today and would like your advice on how to silence (legally) a whole-class scenario where ALL of the students completely ignore you (even though you have never met them before etc). Apparently the group is an amalgam of 2 small low-ability classes, merged for staffing reasons. Teenage students continued shouting, screaming, and ignoring my presence completely. I was therefore completely unable to take the register. The usual counting down from 3, hand-clapping, etc failed to make any impression. In the end, I had to call out for a senior member of staff, also because by then someone's flying calculator had hit me on the arm. This resulted in 2 students being escorted from the room by the SLT followed by some degree of highly reluctant co-operation from the others, although little work was done. (As an aside, one student in the group is officially allowed not to work every time there was a cover teacher taking the class.) I'd be very very grateful indeed for your advice as this has happened before in a new school as a supply. What to do when the entire class is deliberately misbehaving at the very whiff of a "sub". All suggestions of successful strategies very gratefully received!!!
