Study on the Effects of Danmaku Emotion on Video-based Learning

The present study examined the effects of danmaku emotion on video-based learning. Based on one-factorial experimental design, 61 participants were randomly assigned to watch instructional videos in one of three conditions: positive emotion danmaku, negative emotion danmaku, and no danmaku. A Tobii X120 eye-tracker, an emWave system, and a CUBand brainwave tracker were used to record the learners' eye movements, emotional state, and brainwave activities. The learners' learning outcomes were measured with retention and transfer tests. The results indicated that danmaku emotion neither promoted nor hindered learners' learning outcomes; positive emotion danmaku evoked learner's positive emotion and relaxation; the learner's attention was captured by danmaku. The study shows it would be useful to incorporate danmaku emotion on instructional video to induce learners' positive emotions during learning.
