Extended data:

The main characteristics of "micro-course":

1, short teaching time: teaching video is the core content of micro-course. According to the cognitive characteristics and learning rules of primary and secondary school students, the duration of "micro-class" is generally about 5-8 minutes, and the longest time should not exceed 10 minutes. Therefore, compared with the traditional 40-50-minute teaching class, "micro-class" can be called "class fragment" or "micro-class"

2. Less teaching content: Compared with the broader traditional classroom, "micro-lesson" has more problems and prominent themes, which is more suitable for teachers' needs: "micro-lesson" mainly highlights the teaching of a certain subject knowledge (such as the key points, difficulties and doubts in teaching);

Or the teaching and learning activities that embody a certain teaching link and teaching theme in the classroom. Compared with the complicated and varied teaching content of a traditional class, the content of "micro-class" is more concise, so it can also be called "micro-class"

3. Small resource capacity: In terms of size, the total capacity of "micro-lesson" video and supporting auxiliary resources is generally around tens of megabytes, and the video format must be a streaming media format supporting network play online (such as rm, wmv, flv, etc.). ), so that teachers and students can smoothly observe lesson plans online and view teaching plans, courseware and other auxiliary resources;

It can also be flexibly and conveniently downloaded and saved to terminal devices (such as notebook computers, mobile phones, MP4, etc.). ) mobile learning and ubiquitous learning are realized, which is very suitable for teachers to observe, evaluate, reflect and learn.
