Although the Internet has been used successfully to deliver text and limited audio, full-motion video was normally delivered through computers by CD-ROM technology in the 1990s. This study was designed to determine the effectiveness of multimedia instruction delivered by a CD-ROM as compared to a book format correspondence course.
The research questions of this study were: (1) Does the delivery of the same material in a multimedia (computer assisted) format via CD make a significant difference in learning as compared to a book format; (2) Does the multimedia (computer assisted) format make a significant difference in the rate of dropouts compared to a book format; (3) Does the multimedia (computer assisted) format make a significant difference in the sense of satisfaction experienced by course participants as compared to a book format; and (4) Does the multimedia (computer assisted) format improve the speed of course completion?
The sample included 83 professionals who were employed in the baking industry at the time of the study. These persons were selected for the study by three separate baking companies, and each subject was pre-tested and assigned to either the book format or the multimedia format of a newly developed course entitled “Applied Baking Technology.” After the nine month term of the course, each subject was administered a post-test along with a questionnaire. Six of these persons were also interviewed by telephone.
The testing results were analyzed using the Analysis of Covariance with the pre-test scores as the covariate and the post-test scores and lesson means as the dependent variables. The independent variables were the course formats. Testing results were also analyzed using the non-parametric tests of Mann-Whitney U and Wilcoxon. Questionnaire responses were analyzed using t-tests to determine significantly different responses by format.
Results indicated no significant difference in learning by format, no significant difference in dropout rate by format, and no significant difference in speed of completion by format. However, satisfaction and motivation levels as well as the perception of quality were higher with the multimedia format compared to the book format.
