This handbook is based on a field tested training model directed toward preparing regular and special education teachers to teach children in a mainstreamed classroom. There are four components: knowing, diagnosing, developing, and bridging. Seven modules contain the following sections: the major theme, introduction, goals, objectives, instructional activities, resources for further study, and evaluation activities. Modules are designed to develop the following competencies: (1) demonstrate a knowledge base regarding generic factors of human development that influence learning (knowing); (2) use relevant information in planning educational experiences (bridging); (3) demonstrate strategies for facilitating cooperative teaching relationships among regular and special educators (developing); (4) demonstrate creative problem solving skills (developing); (5) demonstrate diagnostic supervisory strategies (diagnosing); (6) serve as a member of a team engaged in writing individual educational programs (bridging); and (7) serve in a continuing education role for a school district regarding clarification of legal and educational aspects of educating exceptional students (bridging).
