Adjacent Display of Relevant Discussion Helps Resolve Confusion

DOI

Discussion fora of instructional videos contain previously-discussed questions and answers. These can resolve many things that a learner might be confused about. However, it is difficult for learners to find relevant content in a static discussion forum that is separated from the video. This paper introduces Adjacent Display of Relevant Discussion (ADRD): it places discussion in a panel adjacent to the video and dynamically updates the content of the panel based on the current time of the video. In a between-subjects lab study (N=20), ADRD helped users resolve more points of confusion, skim and read more discussion comments, and engage more with the video.
