The effect of the use of interactive videodisc technology to present aural tests was studied in the context of college music appreciation classes. Both experimental and control groups were given study guides that identified the aural objectives for each test and specified the location of the musical examples that were to be used to illustrate the objectives. The experimental group was required to take aural tests on each unit in a supervised computer laboratory where a workstation consisting of a computer terminal connected to an interactive videodisc player was housed. The control group did not take the computer-administered aural tests. The effect of the computer-administered aural tests was measured by scores on unit exams taken in the classroom. A significant superiority was found in the scores on unit exams taken by the experimental group. It was concluded that under the conditions of the experiment, there was a significant advantage in requiring the taking of the computer-administered tests. It is noted that even though the video component of the videodisc player was not used, the videodisc technology was more cost effective to obtain and use, and provided more advantages, than the alternative compact disc technology. It is further noted that the individualized instructional method used in the study, Fred Keller's Personalized System of Instruction (PSI), was a significant factor in the increased achievement of the experimental group.
