Breaktime in the school is a period when pupils learn social skills they will need in the world outside. but can also be an occasion for aggression, harassment and bullying. The contributors to this book, who include educational psychologists, playground designers, advisors and practising teachers, give an accessible account of the burgeoning recent research into children's play, including such issues as playful and aggressive fighting and racism and sexism in the playground. They show how an understanding of the area can inform practical action in designing an environment which encourages positive behaviour, in effective management and supervision, and involving the children themselves in decision-making and conflict resolution. The book includes case studies of ancillary staff training and guidelines to help in the creation of a whole school policy at both primary and secondary level. Staff in primary and secondary schools, school governors deciding on budget allocations, as well as local education authority advisors will find it essential reading.
