Behaviour management techniques are used to control or modify student responses in the classroom. Some common behavioural issues observed include answering back, bullying, incessant talking, diverse learner needs, swearing, and not listening. The document provides suggestions for managing these behaviours such as using non-verbal cues, praising positive behaviour, ignoring low-level misbehaviour, and giving clear expectations and consequences. Building rapport with students and tailoring instruction to individual needs can help address the root causes of misbehaviour.
