If you are preparing to be a SW instructor, I highly recommend this course. It provides very detailed guidance on how to teach which language to each target group, elementary/middle/high school. The number of lectures is 194, which may seem overwhelming, but you can choose and focus on what you are preparing!! And in particular, it provides a lot of class materials, and it also provides various reference materials such as tips on video editing, environment settings, and remote lectures. This is the best lecture among Jacob's lectures that I really like ㅠㅠ (Of course, the other lectures are also great!!) It was a very satisfying lecture for me as a current SW instructor, and it was a great help. I think I will keep referring to it as a reference book while I continue my teaching activities. I will do my best and finish the course ㅎㅎ Thank you!
