This study investigated the use in junior high schools of a prototype interactive videodisc, "Seeing the Unseen." The experimental disc contains four lessons designed to teach scientific inquiry skills. Students determine the order of the lessons and interact with the disc by touching the screen to pause, replay, see a series of questions or examples, return to the menu, or move ahead. "Seeing the Unseen" was used to explore five aspects of videodisc technology: (1) the importance of user control and interactivity; (2) the importance of high quality visuals; (3) the potential of the videodisc for promoting inquiry learning; (4) the effectiveness of individual, small group, and whole-class instruction; and (5) the teacher's role in using videodisc technology. Students found it easy to use the disc, and they appreciated the high level of participation and control that it offered them. It combined the dramatic qualities of television with the self-pacing available through books and educational software, and they credited high quality visuals with contributing to the technology's appeal. Most teachers felt that the technology encouraged them to act as a guide or facilitator, although many had difficulty acutally assuming that role.
