It takes a very long time for the teacher to do a web-based course. The development of technology is very fast. We recorded the video. Why did we not show it to the students once?

In 2013, the "American Philosophical Society" (APA) Eastern Conference Center. I quickly walked into the banquet hall. In accordance with the usual practice, guests will be allowed to leave a small amount of free time before the dinner, commonly known as the cocktail moment. Everyone gathers in groups, tasting, smoking, chatting and enjoying a moment. For me, this arrangement is really considerate. When I entered the hall, I looked around and found that there were many job seekers around. Even though they all seemed to learn and knew how to do it, they were frowning and worried. To be honest, I was really not confident in front of these people. All of them are from Koban and hold at least one doctorate in their hands. And I'm just a philosopher amateur, and all the professional training I've acquired in this area is limited - only including the one-year reinforcements offered by MO. In addition, I also participated in a number of other free e-learning projects on a loose basis, provided that I had free time in my free time.

In 2012, by chance, a course introduced on Twitter caught my attention. This is a free resource provided by Duke University to the world free of charge through the Coursera admonishing platform. The subject of the course is very interesting - "Rethinking: How to reason and argue". The content roughly involves knowledge of logic and forensics. I registered this course with a try and completed the homework in accordance with the teaching standards. Before the end of the course, the lecturer and professor released the content of the exam and asked each learner to participate in a field survey. The score of the survey report was the final exam score. After graduating successfully, I clearly realized that a new and highly promising transformation is quietly emerging in the traditional education field and has a strong momentum.
