A completely automated multi-media self-study program for teaching a portion of electronic solid-state fundamentals was developed. The subject matter areas included were fundamental theory of transistors, transistor amplifier fundamentals, and simple mathematical analysis of transistors including equivalent circuits, parameters, and characteristic curves. The media included a tape slide audiovisual presentation, a programed text, a cued text, a sound movie, a workbook, and an RCA transistor trainer. A controlled experiment was conducted, comparing the effectiveness of the self-sufficient multi-media materials, with a conventional instructor/classroom presentation and existing self-study materials from Air Force Extension Course Institute. Even though the instructor/classroom subjects received somewhat higher ratio gain scores, on the average,than the multi-media subjects, this difference was not signigicant. Both of these modes were superior in effectiveness to the extension course materials. The principal measures of this effectiveness were a pretest and a posttest made up of multiple choice items concerning the solid state theory covered. (Author)
