This text provides an introduction to the principles of behavior modification and the specific information needed to apply these principles successfully in a school environment. Emphasis is on closing the gap between theory and practice through step-by-step procedures for developing, modifying, and fading out behavior management programs. Part 1 presents the basic principles in four chapters, which cover a systematic approach to child behavior management, basic principles of child management and behavior modification, procedures for assessment and management of behavior problems, and issues in designing an appropriate behavior management program. Part 2 is on application procedures and begins with a chapter on prevention of behavior management problems in the school, regular classroom, special classroom, and home. The remaining chapters discuss selecting an appropriate behavior management program; management of behavior excesses in the regular classroom, the special classroom, and the home; management of behavior deficits in the regular classroom, the special classroom, and the home. A glossary is provided. (Contains approximately 600 references.) (DB)
