This project was designed to plan a short study self-instructional film for teaching the use of the C and D scales of the slide rule in solving simple problems in multiplication and to produce one of these films. The film was designed to exploit the unique presentational features of a cartridge loading projector equipped with automatic stop and single frame advance mechanisms and to provide a self-instructional mode for teaching the stated device. The sequence followed in determining the appropriate training program to facilitate optimum functioning of the personnel subsystems was (1) task requirements description, (2) task analysis, (3) training requirements description, (4) training analysis, and (5) training program design. The training film was organized into 82 distinct scenes directly related to operational performance. The film used in conjunction with the cartridge loading projector constituted a training device which engaged the learner in both symbolic, covert participation and symbolic, overt participation. (RP)
