Bullying in schools is a widespread phenomenon that has been largely ignored by professional investigators. It is often a covert problem, but once it is put into the context of social interaction, schools are able to respond to it in productive ways. A multifactorial response is best, and prevention is far better than crisis management. One of the most effective preventive measures is team response by all teachers to ensure a two-fold response. Bullying must stop and firm action must be taken to ensure the safety of the victim. Then the social behavior of the bully and the victim must be analyzed and changed. Part 1 explores how to understand bullying, considering bullies, victims, family factors, and social behavior involved. Part 2 reviews what to do about bullying, focusing on the role of the school, prevention, protection, and parents as partners, and presenting some cases studies of successful intervention. An appendix contains workshop and curriculum materials for teacher education. (Contains 7 tables, 6 figures, and 465 references.) (SLD)
