"Institutions are developing online courses that contain rich multimedia, but research shows there is little difference in student achievement when these types of materials are included. However, many studies report the results of the presence, not the access, of multimedia learning objects. In addition, they do not categorize the multimedia as supplemental or required. To better understand the relationship between multimedia inclusion and student success, this study investigates student access of three categories of supplemental multimedia in an online course and uses access data as a filter for comparing student final grades. A summary of statistically significant differences in mean final grades at four levels of supplemental multimedia access is included."

"The construction of asynchronous learning environments often involves the creation of self-paced multimedia instructional episodes that provide the learner with control over the pacing of instruction (segmentation); however, does the amount of segmentation impact learning? This study explored the effects of the degree of segmentation on recall and application of new knowledge and the nature of learner dispositions toward segmentation. Undergraduate students (n = 212) were randomly assigned to engage in a 9-minute multimedia tutorial (ie, instructionally designed video-based presentation) addressing historical inquiry that was divided into 1, 7, 14 or 28 segments (degree of segmentation) where students had control over when each segment began via a "Continue" button. Students' dispositions toward the segmentation-helped learning, made learning easier, made learning confusing, was annoying or seemed appropriate-were also measured. Results indicated that increased segmentation facilitated recall and application; however, learners perceived a high degree of segmentation (28 segments) more negatively. Overall, these results indicate that increased segmentation within a multimedia instructional environment has a positive influence on recall and application, regardless of the learner's disposition toward the segmentation."
