Intended for teachers, this guide defines behavior disorders and discusses their identification and assessment as well as classroom strategies. The first section, a user guide, considers placement alternatives for students with special education needs and provides an overview of the material presented in the remainder of the manual. Section I introduces the concept of behavior disorders. Section II addresses identification, assessment, and program planning for students with behavior disorders, including an identification checklist and summary. A seven-step model for assessment, program planning, and evaluation is presented. The model's seven steps include: organization of background information; identification and application of expectations; organization of assessment information; summary of assessment information; establishment of corrective strategy; implementation of corrective strategy; and evaluation of corrective strategy. The third section describes classroom strategies, including: prevention of behavior disorders; strategies for mild behavior disorders; strategies for severe behavior disorders; and selection and implementation of classroom strategies. The fourth section lists social service agencies and organizations. Related teacher resources and a bibliography appear at the end of each of these four sections. Appendices consist of a glossary of terms related to behavior disorders; specific examples of behavior disorders by degree of disruption/level of security; the Identification Checklist and Summary Form; and Assessment and Program Planning Forms.
