Examples of the use of “Yukkuri Kaisetsu” in robotics education

We are teaching "Fundamental Experiment on Mechatronics". In this experiment, we tried to have students prepare for the experiment by watching a short lecture video, which explains the principle of the experiment, before the day of the experiment together with reading the instruction manual. As a result, we found that while some students were able to gain sufficient understanding, others either did not watch the videos or skipped them, and thus did not fully understand the experiments. In this study, we made a video explaining the principle of the experiment using the “Yukkuri Kaisetsu” slow commentary technique often used on YouTube, etc. The students were asked to watch the video voluntarily, and the results of a questionnaire survey on the ease of understanding were reported.
