ConTag (Contextual Tags) in Video-based Collaborative Learning

초록

This research work designs an interactive and contextual visualization tool called ConTag (Contextual Tag) for video-based learning scenarios. The purpose of this study is to better understand the variation of learners’ interactions and collaborative learning processes supported by ConTag. The system consists of i) contextual tags, ii) word clouds, and iii) transcript pointers. The paper examines how learners participate in and interact with ConTag and evaluates how they perceive their experience. The results indicate that learners actively participated in discussions and took good advantage of ConTag. Learners' interactions included self-reflection, elaboration, internalization, and support, and they showed moderately positive attitudes toward ConTag participation. The implications of using ConTag and its social collaborative tool (Twitter API) are discussed in the video-based learning context.
