A needs assessment of the Grumman E-Beam Systems Group identified the requirement for additional skill mastery for the engineers who assemble, integrate, and maintain devices used to manufacture integrated circuits. Further analysis of the tasks involved led to the decision to develop interactive videodisc, computer-based job aids to enable mastery of the tasks. A training program was designed to enable more efficient use of the job aid. One module was fully developed and implemented. Acceptance of the computer-based format, as well as the technical accuracy of the job, were evaluated. Following the methodology established by the Interservice Procedures for Instructional Systems Development, the analysis, design, development, implementation, and evaluation phases are discussed. Additionally, the many design decisions, and the research supporting those decisions are discussed in depth. Included are considerations of modern cognitive and behavioral psychology, as well as media and simulation fidelity analysis. Supporting information is provided in 13 appendices, and a 30-item bibliography is provided. (Author/DB)
