Abstract: Mathematics is a more abstract and rigorous subject, for mathematics learning can cultivate college students' thinking ability and logical thinking ability. With the advancement of mathematics teaching, the traditional exam-oriented teaching ideas and methods are constantly changing. In the past, teachers actively taught and transferred knowledge, while students passively accepted knowledge, mainly through continuous classroom practice or homework to achieve the purpose of education. Therefore, for many college students, learning is passive, lacking the ability of active and independent thinking. In order to improve the teaching level and quality of mathematics in essence, we need to innovate and optimize the teaching methods of mathematics in colleges and universities. Micro class is a new teaching mode, and has been widely used in the teaching process of college mathematics. This paper analyzes the concept and characteristics of micro class, explores the significance of applying micro class, and the methods of applying micro class in college mathematics teaching.

Key words: Micro class, College mathematics, Application
