Selecting a platform without knowing what is coming right behind it can be risky. Similarly, it is folly to grasp onto a technology without seeing the variety of ways that the…

Included in this thorough overview of the probable future developments in videodisc technology and its role as an educational medium are (1) a review of current educational technology literature on videodiscs, which summarizes a U.S. Navy Delphi Study of videodisc technology use through 1986, discusses a National Institute of Education (NIE) study…

Discusses the design, methodology, advantages, and disadvantages of the Delphi technique and describes a case study to demonstrate its use. The case study explored the nature of future media services in higher education to obtain long-range planning information for educational technologists and academic administrators. Recommendations of the study…
