Examined (n=36) teachers' perceptions and use of interactive videodiscs (IVD) in the teaching of science. Perceptions tended to be positive. Major barriers to IVD usage were limited equipment availability and lack of time to develop and implement IVD-based lessons. (Author/MKR)

Decribes a study which compared computer assisted instruction (CAI) with a parallel paper-and-pencil module to assess the impact on students' achievement and attitudes in chemistry. Supports the contention that CAI works as well or better than more traditional methods and tends to promote positive attitudes. (RT)

Discusses why, when and how microcomputer simulations of biological topics should be used in the classroom. Includes a five-step procedure for creating such simulations using population growth as an example to describe each step. Steps include topic/background material selection, writing program, and making support materials for the simulation.…

Provides background information on videodiscs, including costs, usefulness, features, advantages and disadvantages. Reviews the history of videodiscs and of interactive video, particularly with respect to current performance capabilities. Gives ideas for interactive video use in science classrooms, outlining steps involved in making an interactive…

Describes the three levels of interactive video and what is known about its instructional effectiveness. Lists 33 videodiscs available for science education. Discusses the uses of interactive video in science teaching. (MVL)
