Brycie,
The thing is, the most effective management of poor and disruptive behaviour happens before it starts - in the general 'classroom management' and teaching of the teacher concerned.
In many lessons given by many teachers, even of the classes with the most potential for poor and disruptive behaviour, it doesn't happen - because the teacher has full command of the class from the moment they walk in, expectations are high, tasks are engaging, the 'history' of that teacher with that class is that misbehaviour is dealt with swiftly and effectively so nobody 'tries it on'.
[It's a bit like policing - effective policing of e.g. a large crowd leaving a football stadium is not 'effective punishment once a riot breaks out', it's the carefully planned anagement and observation of the crowd to make certain that no riot ever starts]
I teach my class day in, day out. They are a high-needs, high SEN class from a variety of challenging backgrounds. I have had to manage ACTUAL pooor and disruptive behaviour maybe once after the first week of term (after a couple of incidents in the first couple of days when chiuldren did 'try it on' and found out what heppens). On the other hand, a teacher who covers my PPA has only to walk into the room and take the register before she has to deal with about 5 simultaneous instances of poor behaviour - her classroom management is not very good (and she's therefore being moved to another class after half term, part of her performance anagement).
Same school, same discipline and behaviour 'systems', onbe teacher with good - but almost wholly invisible to the casual visitor to the classroom - class / behaviour management, another with less string skills in that area.
I suppose the point I'm making, Brycie, is that general 'classroom management' often makes specific 'behaviour management of poor and disruptive behaviour' unnecessary - the two are linked.
