In this paper, we report on the practice of effective online lessons using the learner's program execution history and the web conferencing system. Online lessons aimed at completing tasks for a particular group of learners were performed using a web conferencing system. The teacher's materials were presented to learners. Learners were able to ask questions at any time. It was shown that the teacher could grasp the learner's condition and provide appropriate support by checking the learner's program execution history. In addition, it was shown that the lack of understanding of learners could be effectively pointed out even in a short time by providing opportunities for individual guidance using the web conferencing system. Compared to face-to-face lessons, online lessons in programming based on the execution history of the program can be effective while making clear the understanding status of the learners. |
