A Social Network Analysis of Students' Online Interaction in Hybrid Learning - A Case Study of "Media and Teaching" Course

Hybrid learning which depends on online learning is becoming more and more acceptable by learners, especially with the development of network technology and the increasingly open classroom teaching. Learners' online interaction, as an important part of online learning, has attracted widespread attention and practice. However, is there really interaction occurring in online learning, and what is going on about the interaction, and are there any questions about it? Regarding these questions, we take the "Media and Teaching" course as an example in this paper, and give an in-depth analysis about network density, centrality and cohesive subgroups of students' online learning interactions by using SNA. So we can guide students to interact and organize students' online learning by exploring the interaction structure and form of students' online learning.
