I'm new to the CS role and haven't received any behaviour strategies other than to follow the schools policy which is 2 verbal warnings, move the student to another seat, offer time-out or remove them via on-call (they receive a detention for this). It probably doesn't help that cover work can be poor or limited or that I'm covering some classes that haven't had a real knowledgeable teacher all term. Physically, I'm small and can easily blend into Y11 or 6th form (despite being 7y older than them) so I don't have that "presence" that some teachers have. I'm able to quiet a class down and get on with work, but the noise levels will slowly rise to a loud level. If I ask them to quiet down again, half don't hear me or care. I don't really want to be that teacher who screams and shouts because it shows lack of control (and my voice isn't capable of screech for 6 hours a day). If I give verbal warnings or send them out for time-out/move seats, they will move back, or return to the class but will be loud 5 mins later. It's not really a problem with Y7/Y8 as they tend to listen and fear the detention route, it's more the older years who are very chatty and produce little work unless I go through it with them/stand over them for the whole hour (not practical in a 30 student class). How do you manage classes? What are your techniques?
