Research on Online Teaching Effectiveness and Strategies for Improving Teaching Quality -- Based on Data Analysis of Universities in Yunnan Province

Through the survey of online teaching situation of university teachers and students, we mainly investigate the students' understanding of online teaching, their feelings of using online teaching and the problems they encountered in the process of using online teaching, in order to get a more comprehensive understanding of the actual development of online teaching, 882 valid questionnaires were collected. The survey results show that the main problems of online teaching are, on the one hand, the difficulty of communication and interaction between teachers and students, and, on the other hand, the dampening of teachers' and students' enthusiasm and other problems. This paper proposes three ways to improve the quality of online teaching based on actual research results. First, teachers should improve the regular grade and attendance checking system and be good at discovering other functions of online teaching. Second, students' participation in online teaching should be enhanced and online teaching should be combined with other learning platforms. Third, students should have a clear learning task and strengthen the communication with teachers.
