This chapter on positive behavior management is taken from a guide to designing, implementing, and evaluating instruction and services for students with disabilities. The chapter describes considerations in designing positive management programs to prevent inappropriate student behaviors, foster the development of student responsibility, and respond to behavior problems in a way that supports students and promotes their learning of appropriate social and classroom behavior. The chapter outlines the components of positive behavior management systems; the benefits of a positive approach to management versus punitive discipline; guiding principles and specific strategies to foster positive, responsible student behavior; and methods of implementing the strategies by school leaders. Appendices list resources for informal needs assessment for planning student support programs, classroom strategies for promoting positive student behavior, administrative strategies to promote positive behavior management, and 12 commercial programs/resources for social skills instruction. (Contains 25 references and a list of 20 additional resources.) (JDD)
