This study examined eight areas that are related to the problems of authoring and producing training-oriented videodiscs: the delivery system itself; media selection during instructional systems development; instructional strategies; author mock-up and simulation prior to premastering; premastering; mastering and replication; composition of videodisc authoring teams; and evaluation alternatives. Information and data were gathered through the study and documentation of two ongoing videodisc projects; visits made to industrial training sites and production laboratories and studios in the United States and Europe; discussions held with representatives from military and civilian organizations; a technical literature search; and participation in recent conferences related to videodisc technology. It was concluded that optical videodisc technology and the authoring technologies associated with it are still in a state of flux and can be expected to be changing and evolving during the next five years. The Navy is advised not to plan to deploy videodiscs widely in the immediate future, but to continue to track the rapidly developing knowledge in the videodisc field. (Author/CMV)
