AdaptReview: Towards Effective Video Review using Text Summaries and Concept Maps

Abstract: Video review is commonly performed by learners to clarify or make up for the content they have missed. However, it is not well supported in the current video learning environment. In this paper, we investigated the design of techniques to facilitate effective video review. Through a preliminary study, we observed learners’ review behaviors, identified their challenges, and derived three design goals. We then designed two review techniques, concept map based review (CMReview) and text summary based review (TSReview). Evaluation studies were conducted to understand learners’ post-review learning performance and review experiences using both techniques on short and long videos. Results showed similar learning performance for short videos across both techniques, but CMReview improved understanding for long videos and was preferred by most users. We conclude by discussing implications for integrating with current video learning platforms.
