This research investigated how use of an interactive videodisk information system, the Strategic Teaching Framework (STF), helped preservice teachers expand their visions of teaching, learning, and assessment in mathematics, and helped develop their skills in translating that vision into action in the classroom. STF consisted of videos of classroom situations, with various behaviors and techniques on display. The technology was used as one element in the field experience component of a Master's certification program for prospective elementary teachers, and provided them with models of effective teaching around which class discussions and individual journal reflections were based. The data that was collected documents how students felt about the value of specific STF features, STF's "fit" as a curriculum component, and STF's impact on understanding. Reactions indicated that STF aided students in class arrangement, self-criticism, and feedback to fellow learners. It also stimulated reflection about teaching philosophies that continued to develop throughout the course. (Contains 24 references.) (Author/BEW)
