Behaviour management in the classroom and playground is one of the most challenging aspects of teaching. The new edition of Behaviour in Schools offers a comprehensive overview of the major theories of behaviour management in primary and secondary schools, illustrated with detailed case studies. The theories covered range from teacher-dominated methods to more democratic approaches. They include assertive discipline, applied behaviour analysis, the new cognitive behavioural approaches, neo-Adlerian theory, humanism, Glasser's control theory and systems theory. The emphasis is on proactive approaches to discipline which allow teachers to achieve their educational and social goals for their students and themselves. Porter also shows how to enhance students' motivation and help students become confident and independent learners. Maintaining the balance of theory and practice, the new edition has been fully updated in light of recent research, including a strengthened discussion of inclusion and anti-bias curricula, and sections on motivation and self-esteem. References have been also been updated, making fuller use of UK research. Behaviour in Schools is a textbook for education students and a reference for experienced teachers who want to improve their ability to cope with disruptive behaviour.
