VideoScape: Augmenting Video Learning Experience with Concept Map

Videos have become privileged materials for on-line learning. However, the usability problems of video lectures still limit learners to retrieve information based on their needs. For example, learners can’t decide whether to watch a video by previewing at a glance, find video section based on demanded concepts, or personalize their learning environment for next time review. Furthermore, it is hard for learners without enough metacognitive skills to understand the lecture and reflect on their understanding without instructors’ support. This paper aims to improve video learning experience through the augmentation of interactive concept maps. We introduce VideoScape, a video learning system that extend a web-based video player with a time-anchoring and editable concept map to facilitate video browsing and provide metacognitive support. By conducting a qualitative evaluation study with online learners, we find that VideoScape can effectively help participants organize their knowledge, preview and review the lecture, track their progress, reflect on their understanding and navigate the video.
