The primary aim of this book is to bring to the grade school teacher a survey of the most recent techniques and ideas of behavior modification which are applicable to good classroom management. All of the approaches and techniques presented could be of interest to teachers working at all grade levels. Since research has shown that the systematic application of behavior modification principles can bring about needed behavior change in educational settings, the teacher must assume the role of behavioral engineer and through the application of behavior modification techniques create a classroom atmosphere that not only leads to desired instructional outcomes but reduces the chances of a child learning inappropriate responses. Hyperactive, aggressive, negativistic, dependent, and withdrawn children are discussed as well as specialized techniques for handling these children: vicarious reinforcement, negative practice, self-monitoring behavior, behavioristic reviewing, behavioristic psychodrama, adjustment inventory, and the sociometric technique. References are included. (Author/SES)
