A description of the DAVID interactive instructional television system and its application to post-high school...

This describes the unique DAVID instructional system, which merges motion, color, and audio capacities from instructional television with individualized student interaction, answer analysis, immediate reinforcement, individualized lesson content, branching, and data gathering from computer-assisted instruction. DAVID (Digital And Video Interactive Device) instruction includes drill and practice, tutorial, and dialogue strategies based on existing and new TV lessons. The system was created for the National Technical Institute for the Deaf by Dr. vonFeldt and was operational in November 1977. This paper includes (1) a description of deaf student needs, which were the basis for system development; (2) description of the completed prototype (DAVID); and (3) results of preliminary testing of the system with deaf students.
