The development and implementation of an inservice program to assist teachers in translating general provincial social studies guides, "Experiences in Decision Making," into specific units of instruction are described. The rationale for using a series of video tapes on unit planning and a matched series of print materials was to make effective use of mass media knowledge sources, complemented by lead teachers providing interpersonal communication vital to teacher adoption of the innovative materials. The objectives, components, program guide, planning chart, and lead teacher activities are outlined in the program description. The four-step sequence of the operation, involving pre-broadcast activities, discussion with lead teachers, broadcast viewing, and follow-up activities, are described in a case study of a local school system. Evaluation techniques included a pretest and post test on the content of the videotapes, staff interviews, and an opinionnaire administered to lead teachers. Recommendations are suggested to improve the satisfactory results of the inservice program. (KSM)
