The investigation examined which of four instructional materials or combination of materials best prepared students to achieve the objective called "Introduction to Instructional Design," which is an optional objective of the Brigham Young University Individualized Secondary Teacher Education Program. The student must identify the premise underlying the Modified General Model of Instruction (MGMI), identify its sequence of steps, and classify written descriptions of the various activities. Several strategies of preparation are possible, and it is these that are to be validated in the investigation: 1) no preparation, 2) watching a film strip accompanied by cassette tape, 3) reading and studying a written description of the MGMI with examples, or 4) using a combination of preparations 2 and 3. By using a posttest-only control group design, it was shown that neither the written materials alone nor the filmstrip/tape alone was as successful as their combination. Of interest was the finding that the results of students using the written materials closely paralleled the scores of students viewing the filmstrip/tape, although neither of the two instructional methods performed well in preparing students to achieve the objective.
