The course content was very helpful. I was able to learn about approaches to problems and what kind of thinking is necessary. However, there were some disappointing aspects. This is just my personal opinion, but if these points are reflected, I think you could create an even better course. 1. It would have been better if it were more organized. There were many filler words like "um...", "uh...", "so...", "I mean..." It felt like you were speaking as thoughts came to mind without proper organization. For the teaching materials, it would be better if they were organized so that you don't have to go back to previous pages to explain again and then return. 2. The lectures felt too fragmented. Some were less than 1 minute long in the shorter cases. You must have divided and edited the videos according to your intended structure, but I felt that videos that are too short break concentration. It would have been better if there were comments like "We'll continue in the next lecture." Since this isn't a live broadcast course, if you take more time in creating it, I think you could make the best course possible.
