Part I : A Rationale for Interactive Videodisc Instruction 1 Classifying Types of Instrt

ABSTRACT The purpose of this paper is twofold: (1) to outline the issues involved in designing videodisc-h'sed instruction to meet the needs of the public high school, and (2) to describe the approach tieing used in one project that is developing videodisc-based courseware for high school math and science instruction. The first of two major sections presents a rationale for interactive videodisc instruction, a description of a four-level classification scheme for instructional videodisc configurations, and a discussion of the educational implications of the different levels. It is pointed out that videodisc-based courseware can be designed to work effectively in both Level 1 and Level 3 delivery systems; this dual approach to courseware development appears particularly suitable for use in public school math and science instruction. The second section summarizes the development of a series of interactive videodiscs, "Core Concepts in Math and Science," including Instructional format, development and validation procedures, and observations from the field testing. It is concluded that the combination of interactive videodisc technology, selected instructional design, and mastery learning procedures provided the teacher with a flexible and powerful resource. A list of references is appended. (JB)
