Multimedia is increasingly used to enhance human-computer interaction in a variety of formats (text, graphics, audio, animation, and video). The challenge is how to use the most effective presentation format that would result in performance improvement. This paper addresses the added value of video presentations in a technology-mediated learning environment for a basic Management Information System course at MBA level. We postulate two hypotheses that take into account students' mastery learning and satisfaction with regard to the usefulness of video presentation, moderated by students' self-interest to learn the subject matter (i.e., intrinsic motivation). Our analysis, on the basis of empirical research, shows that the subjects find a learning environment supported with video presentations is more useful. Their intrinsic motivation to learn the subject matter had a significantly positive effect on their satisfaction with the availability of video presentations. Video presentations had no significant effect on their performance on exams, however. (Contains 6 tables and 1 figure.)
