[Summary from: MERLOT, 2009]
This research describes the evaluation of video tutorials used in a graduate level online statistics course. The evaluation focused on attitudes toward the tutorials and differences in academic performance between online sections that used the tutorials and those that did not. Attitude results were based on 78 students who completed an online survey and indicated positive perceptions of the tutorials. The quantitative findings were supported by narrative comments that suggested the tutorials were an effective component of the course. However, comparisons of sections with and without access to the tutorials showed no statistically significant difference with respect to academic performance. These results suggest that video presentations used as supplemental materials may provide instructional designers with a tool to create online courses that are as effective as traditional face-to-face courses.
