| Abstract: | This article proposes a computer-mediated education system, which uses discussion-embedded lecture videos. Currently, lecture videos and online discussions exist separately, and discussion topics are managed without reference to the lectures. However, when the discussion is based on the lecture, this separation makes it difficult for the participants to comprehend the discussion and contribute to it. In this article, the author proposes a system that works on the basis of a close relationship between the lecture video and the discussion. In the proposed system, the contributed comments are embedded into the corresponding parts of the video. Therefore, participants can read related discussions while watching the lecture video and they can watch the corresponding part of the lecture video while reading the discussion. Participants can appreciate the relation between the discussion and the lecture and understand the content and background of the discussion more deeply. These advantages facilitate further discussion. Thus, a more effective distance learning education environment can be achieved. |
