Using Topic Maps Standards to Improve Note-Taking/Sharing in Video-on-Demand Based Self-directed Learning through Visualization

Abstract

Recent development in streaming video and information technology have made it possible for us to access videos of our choice without the restriction of time and space. There are countless videos with educational values being made and uploaded on video-sharing websites by educational organizations and enthusiastic individuals. However, most people have experienced difficulties in note-taking in VOD based learning, which is considered to be an efficient learning process for knowledge building. The purpose of this research is to improve the note-taking of self-directed learners using online educational videos, and in the meantime, promote collaborative note-sharing. In this paper, we introduce a model which visualizes basic note-taking behaviors in VOD based learning by introducing the Topic Maps standards. Then, we design a system which is expected to help the learners construct a knowledge structure while making tags, annotations and comments to the video in accord with the timeline of the video stream, and meanwhile reviewing and sharing notes via collaborative note-taking features.
