Abstract: Based on the modularity idea，teaching links are designed in seven steps to strengthen

classroom in- teraction，the cultivation of students' ability to apply knowledge，and ideological and

political education. The com- bination of Tencent Classroom and Cloud Class is used for live

network teaching. Classroom management adopted multiple models，such as inviting counselors

to co-manage，introducing fault-tolerant mechanism，paying attention to students' emotional changes

and other measures to improve students' participation in the classroom. The average attendance

rate reaches 98% . The examination is based on the Super Star Learning Pass and is

conducted in the form of open-book examination with a large number of questions. By comparing

the students' scores of offline exam- ination in recent three years with that of the online

examination of this semester，it is found that the distribution of students' scores of this semester

is more reasonable，which indicates that online teaching has certain advantages.
