Developing a Video-based e-Learning System Incorporating a Fill-in-the-blank Question-type Concept Map

E-learning, which can be used anywhere and at any time, is very convenient and has been introduced to improve learning efficiency. However, securing a completion rate has been a major challenge. Recently, the learning forms of e-learning require learners to be introspective, deliberate, and logical and have proven to be incompatible with many learners with low completion rates. In this study, we propose an e-learning system that incorporates a fill-in-the-blank question-type concept map to deepen learners' understanding of learning contents while watching learning videos. The proposed system promotes active learning reflectively and logically by allowing learners to answer blank question labels on concept maps from video content and labels associated with the question labels. We conducted an experiment with 14 subjects to evaluate our proposed system by comparing it with a conventional video-based e-learning system and confirmed that the proposed system promotes active learning while watching lecture videos and is effective in improving the comprehension of learning content for learners who are unfamiliar with video-based learning.
