The primary long term objective of this proposed research is to create quality videodisc based science and mathematics instructional materials using a process referred to as "repurposing" a videodisc. In this approach, new computer software is developed to accompany, and/or incorporate visuals, audio, and other information from PREVIOUSLY developed, commercially available videodiscs. Via this approach, the creation of interactive materials is simplified and becomes less expensive because some costly and complicated time consuming tasks are eliminated, e.g., pre--and post-video production, and mastering. In this research, emphasis will be placed on improving technology based tools and systems for classroom teachers, and all learners, including the learning disabled. To implement these improvements utilizing the "repurposing" approach, two key systems development objectives surface: 1) incorporate videodisc motion and still segments whenever possible to enhance VISUAL aspects of the learning experience, and 2) expand the AUDITORY component of existing videodisc presentations by incorporating digitized audio in the accompanying software. Although several generic and archival videodiscs have been produced commercially to encourage educational "repurposing" activity, the legal issues relative to copyright infringement require clarification. This research addresses these issues to encourage commercial development of "repurposed" videodiscs. Anticipated Result A successful Phase I research project will result in: 1. Legal guidelines for videodisc "repurposing" activities. 2. An online database of commercially available videodiscs. 3. Instructional development guidelines for "repurposing". 4. Interactive computer based science instructional tools with enhanced VISUAL and AUDITORY components. Amplifying accomplishments in Phase I, Phase II will result in: 1. An up-to-date online database of available videodiscs. 2. A series of science and mathematics instructional systems which incorporate "repurposed" videodisc units ( using the legal and design guidelines established in Phase I). 3. A videodisc "repurposing" workshop/seminar. Successful completion of the research implies the commercial availability of less expensive videodisc-materials with enhanced VISUAL and AUDITORY emphasis to meet various learners' needs.
