Dr Annemieke Golly has identified five universal principles for managing in-class behaviours of children with challenging behaviours: being respectful, modelling behaviours, having clear expectations, maintaining routines, and dealing with chronic misbehaviours. She illustrates how to implement these principles in the context of a school-wide positive behaviour support system. In addition, Dr Golly looks at the two main areas of chronic misbehaviours: attention seeking and escape/avoidance behaviours and shows how to identify and work with them.
