| Abstract: | Two experiments examined the effects of a multimedia technology referred to as “Time Compressed Animated Delivery” (TCAD),
on student learning in a junior-level reproductive physiology course. In experiment 1, participating students received one
of two presentations of the same instructional material: TCAD and a lecture captured on video. At the completion of each presentation
a test was administered and group mean test scores computed and compared. The results were statistically significant (df = 362, t = 10.623, p < 0.05), favoring the TCAD treatment group. The effect size estimate was 1.14. In experiment 2, student learning from three
groups were compared on the same reproductive physiology unit used in experiment 1: (1) TCAD, (2) TCAD without the 3-D component,
and (3) video-lecture. After removal of three poor functioning items, a one-way analysis of variance was computed. The results
were statistically significant (df = 2, F = 2.351, p < 0.10). Results of post hoc comparisons showed that differences in mean test scores between the TCAD and control groups
were statistically significant (p < 0.05). The effect size estimate was 0.25. These findings provide preliminary evidence for use of TCAD. |
