Instructional Hurdles

Before developing the interactive video system, Schrock used standardized films and tapes to demonstrate instruments in class. This method created problems, because studnets who were familiar with a particular instrument were bored with the classroom instruction on it.

At the same time, students who had enver seen the instrument often wouldn't gain and adequate recognition of its characteristics and sound. That recognition, Schrock says, is a crucial link to understanding the recorded examples and tests presented later.

Hiring musicians to play in the classroom is, of course, the ideal means of teaching music, but it proved to be too expensive and did not fir the time constraints of a class period. The interactive video application hurdled these obstacles.

First, it allowed students to learn at their own pace, checking out the software and logging onto one of the four workstations in the college's technology center. Second, the instruments' range, timbre and characteristics are presented as accurately as possible without the use of live musicians.

The Creation Process

In designing the system, Schrock and Smith wanted to produce the highest-quality sounds and images while making the system easy for students to use. They chose video- discs from the University of Dela- ware Media Center for their video images and stereo sound; they hired professional musicians to perform additional demonstrations of timbre characteristics not provided on the videodiscs.

The demonstrations were re- corded onto VHS tape with a high- fidelity stereo to maintain good sound quality in the playback mode. As a result, students have access to a variety of individual instrumental timbres in solo roles, accompanied by a variety of ensembles recorded in high-quality image and sound.

Finding software to run the sys- tem and withstand heavy lab use was a more difficult problem, how- ever. After experimenting with dif- ferent packages for several years, Schrock chose software from Waconda Interactive Video, Inc. …
