Educational videodiscs can provide effective instruction, but the cost of hardware needed to perform the desired system functions have been a limiting factor in videodisc use in the classroom. However, many videodisc applications can be adequately and effectively approached with much less than the ideal system, and very little attention has been given to maintaining an effective, inexpensive system. A basic level 1 system--consisting of a videodisc player with a handset for interaction and a standard television monitor--can be extremely effective when coupled with a well conceived lesson. For example, a videodisc of the opera "La Boheme" is available that can be used with an index developed by the University of Delaware to introduce students to the musical concepts in the score. While this interaction can be accomplished without computer control, it can also be easily upgraded to a level 3 system with computer control. The University of Maine has also developed study guides to accompany the compact disc of an orchestral work, Tchaikovsky's "Romeo and Juliet." An index provides a list of significant locations than can be randomly accessed by the videodisc player as well as identifying main themes and many other musical events. Again, the index information can be used to create a lesson without the use of a computer, or can be easily upgraded to use a level 3 system with a computer. Two equipment references and eight journal articles are listed. (EW)
