Abstract: With the continuous increase in the contact rate of digital reading methods, digital reading has gradually become the mainstream reading method. College students, as a group with a higher level of education, are the main groups to receive, spread, and enjoy digital reading. They often use informal groups such as interest groups, book clubs, and fellow villagers in the digital reading process. The establishment of informal groups, the dissemination and interaction of reading content have a significant impact on the effect of digital reading. In this regard, the author uses "digital reading" as the starting point and adopts action research methods to explore the strategies for guiding the informal group development of college students in the process of digital reading from the perspective of group dynamics.

Key words: informal group of college students, group dynamics, digital reading
