The author of this handbook maintains that substantial school improvement can take place only within an orderly environment. To achieve a positive educational climate, he lists numerous suggestions to handle school discipline problems. Individual chapters cover conducting a campaign against crime and violence, handling discipline problems effectively, helping teachers reduce discipline problems, unrigging the school (including improving students' self concepts), increasing student involvement in school activities, and improving student morale by modifying the curriculum. Two successful discipline improvement programs, one in an urban high school and one in an elementary school, are described in detail. An annotated bibliography is appended. (Author/DS)
