As a result of declining scores, the National Science Foundation has funded numerous materials-development grants. Largest among these is the Interactive Media Science (IMS) Project at Florida State University (FSU) in Tallahassee. This project's mandate is to design, develop, and produce six level III interactive videodisc programs for middle school science instruction. These innovative programs will provide students with numerous opportunities to become involved in activities that would be impossible for them in the normal classroom setting. Using the ScienceVision program, students are able to conduct experiments, visit locations, listen to experts, make decisions, collect data, and solve the problems posed on the videodisc. Factors influencing the design and development of the six discs are: (1) prior research into instructional videodisc technology; (2) characteristics of the target audience; (3) capabilities of the medium; (4) the inquiry-based learning philosophy advocated by the project; and (5) the state of technology in the schools. Developed by experienced teachers, the program was also designed to address the limits of the classroom. The fundamental assumption of ScienceVision is that science education should be multidisciplinary and should provide a general science background for all students. The goals of ScienceVision are twofold: to provide students with a valid understanding of science as a human enterprise and to present science as a search for knowledge based upon interpretation of data. The content, context, cognition, inquiry-based learning, reasons why level III interactive videodiscs should be used, classroom structure, hardware requirements, research with ScienceVision, and educational implications of ScienceVision are topics of discussion. A list of contact persons is included. An overview and status of the project's products are appended. EcoVision, ErgoMotion, AstroVision, Chemical Pursuits, Life Skills, TerraVision, and Water and Weather are the programs that are described. (KR)
