What is a "micro-course"? What is the difference between micro-lessons and teaching, lesson fragments, micro-lessons and micro-lessons?

What is a micro-course? There are many definitions about the concept of "micro-lesson" on the Internet. But in general, micro-lesson is to digitize teachers' courses by digital means. The biggest advantage of digitalization is that it can take the place of teachers in class, and students can watch it repeatedly anytime and anywhere. This is the biggest advantage of micro-courses. What the micro-course should do is not to make the text teaching materials sound. If it's just sound, no one needs to read it, because the computer can read it directly, so why let the teacher read it? Because people have emotional attitudes and values, tacit knowledge cannot be achieved by computer voice translation. That micro-lesson is to record the teacher's explanation and understanding of the course.

What should be recorded in the micro-class? The first point is to record the teacher's personal understanding of the teaching content; The second micro-lesson records the teacher's educational strategies, teaching methods and his emotional activities with students.

I think "micro-lessons" should be divided into three categories: the first category is micro-lessons in Li Yuping, the second category is micro-lessons in Foshan, and the third category is micro-lessons in Khan. Why do you classify it like this?

According to the three contents, Li Yuping's micro-lesson is the "three small" research of course teaching (paying attention to small phenomena, developing small strategies and accumulating small stories). He has done PPT digital stories for teaching activities, and all his teaching scenes are reflections and summaries of teaching. His idea of teachers' professional development is really popular with teachers, and many provinces and cities in China are studying it.

About the micro-courses and feasible micro-courses in Foshan-Foshan micro-courses recently held a competition and won the first prize. At first, there were a lot of course records, and then the course records were intercepted for 3 or 5 minutes. Now, with the popularization of the concept of Khan Academy, there are some schools similar to Khan in Foshan micro-courses, but their main body is still based on course records. It is made by putting three cameras in the classroom. Recorded from different seats, and then sliced, one of its objects can be used as micro-class teaching, that is, teachers see their own teaching situation, and the other is to invite the Ministry of Education to participate in the competition.

At the same time, correspondingly, it is slightly different from the teacher's definition, and there are still three key words-the first is time, 10 minute; Secondly, it has teaching objectives; The third one is about a problem. These three key words determine its characteristic that what you say is short and pithy. Having said that, some people may have questions: Why is a class 10 minutes instead of 20 minutes, 30 minutes and 50 minutes?

Foreign brain science research has found that students' attention is very high at the beginning of class, and it drops after 10 minutes. If the teacher changes the method and content, everyone's attention will always be low, and then the class will be over, and they will be very excited after class. I don't know if you believe it or not.
