This final report describes the Case Method of Instruction (CMI) Project, a project to develop, field test, and disseminate training materials to facilitate the use of the Case Method of Instruction by inservice and preservice instructors in developmental disabilities. CMI project activities focused on developing a collection of case stories and related training activities and materials for instructors in case method instructional strategies. The benefits of CMI are identified, including: an emphasis on problem-solving, use of real-life situations, and active student participation. The 23 case stories developed address three major areas of training: working with families, interdisciplinary and interagency collaboration, and child-level interventions. Instructional materials for the case studies include role plays, discussion questions, small group activities, team simulations, and written assignments. Field tests indicated the case studies and training materials were perceived to be of high quality and useful. Application of CMI in a preservice graduate course on families indicated students demonstrated a significant increase on measures of family-centeredness as a result of the course. Individual sections of the report address the project's goals and objectives, conceptual framework, logistical difficulties and departures from original plans, evaluation findings, impact, and future activities. Appendices include a field-test review form, a CMI survey form, and reviewers' comments. (CR)
