ABSTRACT
Efficient learning with cases requires discussion on the facts of the case as well as on their meaning. We investigated the focus (factual vs. abstract) of a case-based learning discussion when video was added to a chat-based learning system. Students whose first experience includes high-quality video, focus significantly more on abstract knowledge than students first exposed to chat-only or chat + low-quality video. We also found that these students expressed a preference for face-to-face discussion. We conclude that video may improve learning where discussions on abstract and concrete knowledge are important.
