Book excerpt: Disruptive classroom behaviours can prevent effective teaching and create a negative learning environment. This handy directory of behaviours has been written by teachers for teachers, and is bursting with tried and tested techniques to make the classroom a happier and more productive place for everyone. The 'Kit Bag' is a bank of up-to-date ideas that can be dipped into whenever needed, each one intended to get children focused and more engaged and excited by the learning process. The book suggests ways to create a positive learning environment in the classroom and encourages teachers to be proactive at the most vulnerable times of the school day such as at the start and end of lessons. Strategies are included for addressing behaviour hotspots, such as calling out, frequent crying or aggressive behaviour, as well as how to uncover the source of these problems and practical ways to prevent them from reoccurring. The useful Self-Assessment Checklist will also aid in making sure teachers are constructively reinforcing positive behaviour at all times. This widely acclaimed approach will be a must for any teacher who has ever been confronted with challenging behaviour and wants to get the best out of their pupils. It will also be a valuable tool for headteachers and senior leaders who want to revolutionise current school practices.
