This project, stemming from work started under the National Science Foundation grant "Development of a Television Computer Assisted Instruction (TVCAI) System" SER-7806412, called for the transfer to videodisc of some of the videotape materials developed under the grant. Three efforts were included in the proposal: design and development of hardware and software for the intelligent videodisc system, design and selection of courseware for the system, and courseware evaluation. This report contains a summary of the work completed in support of intelligent videodisc systems. Hardware and software developed, the videodisc produced (which contains physics materials), and the demonstrations given of the intelligent videodisc system are discussed. In addition, the report contains a description of current work both in extending the usefulness of the intelligent videodisc system and in support of other users. General remarks concerning the appropriate use of intelligent video systems in education are also included. Timing differences, Video-computer Courseware Implementation System (VCIS) video documentation, and lists of demonstrations/workshops and publications are included in appendices. (JN)
