Abstract

The increased availability of moderately priced, good-quality digital audio computer cards and computers with built-in audio capability have enabled trainers and educators to realize the potential of random access audio for computer-based training (CBT) and other multimedia applications. In this study, the researchers investigated the effectiveness of adding digital audio to CBT. The experiment was conducted at the University of Central Florida in the spring of 1991 with 60 students enrolled in an undergraduate Applications of Technology in Education course. Three course sections were randomly selected from a total often intact course sections. Students in these three classes were randomly assigned to one of three treatment groups. Each treatment group completed an identical CBT program in one of three conditions: text-only delivery, full-text and totally redundant audio delivery, or partial-text (bulleted) with full-audio delivery. Major findings of this study were: (a) there was no significant difference among the three treatment groups in achievement gain; (b) there was a significant difference in the mean completion times across the three treatments, with the text-only version requiring the least time on task; and (c) student perceptions indicated a high degree of program acceptance across all levels of treatment. © 1993 Taylor & Francis.
