After this concept was introduced into China, it was gradually improved by some domestic scholars, which is more suitable for the actual situation in China. Hu Tiesheng proposed that micro-lesson is a new online video course based on micro-lesson teaching video and designed and developed for a certain subject knowledge (such as key points, doubts, difficulties, test sites, etc.). ) or teaching links (such as learning activities, themes, experiments, tasks, etc. ) and support a variety of learning methods. Micro-course has the characteristics of short video time, prominent teaching theme, small resource capacity, strong interaction, wide application, exquisite teaching design, wonderful teaching activities and concentrated explanation of a problem. Some college teachers don't study the concept of micro-courses too much, but study how to combine micro-courses with teaching science, carry out a series of teaching method reforms and improve teaching quality.

Second, the application of micro-courses in the process of mathematics teaching in colleges and universities

With the informationization of society, electronic products have changed the way students study and consult materials. Therefore, if students can use these devices to browse the teaching content after class, it will be a good way to connect with classroom teaching, and it will naturally be an extension of classroom teaching, and will soon become a new teaching mode. Multimedia technology is becoming more and more mature, and colleges and universities also require teachers to master certain multimedia technology. Almost all teachers have used multimedia to play videos, but you will find that few students actively browse these videos for learning after class, and the utilization rate of videos is very low, whether it is excellent course videos or other types of teaching videos. Micro-course has the characteristics of clear goal, prominent theme, short and pithy, video-based and easy to use. College students can use micro-lessons to review and consolidate what they have learned.

1. The Relationship between Micro-course and Mathematics Teaching

Mathematics is one of the most important basic courses in universities. Teachers in universities should not only teach students professional knowledge, but also teach them correct learning methods. For some relatively simple knowledge points in mathematics courses, teachers can boldly adopt the method of micro-lesson, which requires teachers to use micro-lesson flexibly, rather than deliberately using it for the purpose of using this teaching method. Teachers should seriously discuss and study knowledge points according to their own experience, flexibly use different teaching methods and teaching means, scientifically and effectively choose teaching methods, and improve classroom teaching efficiency.
