Montevidisco is an interactive videodisc application intended for intermediate Spanish students. It combines language enrichment with elements of role-playing games as the student plays the role of someone visiting a hypothetical city in Mexico, interacting with native Spanish speakers in native situations via videodisc. The concept originated at Brigham Young University in the early eighties, with the video filming done at that time. More recently, the BYU Humanities Research Center has adapted the original material to run on standard microcomputer platforms.

There are three implementations of Montevidisco in various stages of development. The first is a side-by-side version that uses a HyperCard stack on a Macintosh to control a separate videodisc player and monitor. The second version uses a video overlay configuration with ToolBook and Windows on an IBM platform. Both of these versions are 'finished' to the extent that they are being used in intermediate Spanish classes at BYU and elsewhere. General marketing arrangements are expected to be finalized this summer. The most recent implementation uses QuickTime on a Macintosh to display digitized video directly from the computer's hard disk.

This paper begins with an explanation of the general features of Montevidisco that are common to all three implementations. It outlines some of the design considerations faced and explains how the choice of metaphor influenced those decisions. Some questions that have been raised during the testing and review process are also addressed. The paper then categorizes the significant differences between the three implementations and discusses the technological and pedagogical reasons for them. It concludes with a status report on the QuickTime version and gives an assessment of this new digital video technology in an instructional environment.
