Abstract: Linear algebra is a basic course in universities, and it is also the basis of other subjects. Linear algebra has many concepts and theorems, and it is one of the most abstract mathematical subjects. According to the new requirements, it is an urgent problem that how to do online teaching. Because of the rapid development of information technology, online teaching is feasible. Based on the concept of student-centered, some explorations and attempts are made in online teaching of linear algebra from three aspects: before class, during class and after class. It has been proved that the just-in-time online learning can motive students. Guaranteeing both quality and quantity of teaching tasks, it can not only help teachers achieve better teaching effect but also help students improve the learning ability and problem-solving ability.
