There is an advantage in that it provides various practical exercises. Despite this, there is a problem. When explaining, it is not expressed specifically, but rather, it uses a lot of pronouns such as “this, that, this like this.” Therefore, you have to look closely at the mouse pointer on the screen and examine in detail what operations and actions are being taken. It does not feel like sharing and explaining clearly existing names and techniques, but rather like recording and demonstrating what you are doing. I think this is an area that must be improved if a new course is created in the future. Because of this, students become more tired and it is difficult to organize the content.
