The paper describes Miss STIM, an electronic teaching aid designed to increase the computer's educational potential for severely handicapped students. The aid incorporates both video images and audio signals and is programed to present lesson material in conjunction with responses from the student. System operation is described in terms of stimulus generators, student response recorders, video monitors, and computerized control devices. The student's physical responses are recorded on videotape for the instructor's use. The educational material is presented by means of disks performing three functions: coordination of different electronic components, control of audio/video images from the videodisc players to the monitors, and data storage for individual student files following completion of a lesson. Versatility of the unit is stressed, and new programs under development are described. Appended materials list the main computer program menus and sub-menus and briefly describe a series of educational materials scheduled for release in 1986-87. (CL)
