This textbook is designed for use: (1) as a text in college classes in curriculum and instruction, educational administration, public policy, school counseling, school psychology, and the social psychology of education; and (2) as a resource for inservice training of school administrators, staff personnel, and teachers. The book focuses on organization development (OD) in the schools as a way to bring about constructive changes such as improved school climate, interpersonal and interprofessional communication, student achievement levels, and effective teaching. Eleven chapters are titled as follows: "Theory and Technology,""Macrodesigning,""Clarifying Communication,""Improving Meetings,""Solving Problems,""Making Decisions,""Working with Conflicts,""Microdesigning,""Diagnosis and Readiness,""Evaluation," and "Institutionalizing OD in School Districts." Chapters contain numerous figures, exercises, handouts, questionnaires, and other tools useful to students and educators. Chapters are designed to be read and used independently from the rest of the book as well as in thematic clusters. Chapter 11 describes several local self-help groups of organizational specialists and suggests ways in which schools may be similarly able to utilize the services of such experts in the field. Extensive references are appended. (IW)
