Focusing on the ideological and political education of college students, this paper studies the characteristics and laws of college students’ participation in network public opinions in the current Internet environment from the perspective of communication science. The emergence of campus network public opinions is influenced not only by the mechanism of the Internet media platform, but also by the media literacy of college students themselves. There is a management vacuum in campus communication, which leads to the emergence of campus public opinions. In order to minimize the impact of public opinions on campus, different entities need to play an active role, understand the triggering factors and process, observe the characteristics of public opinion fermentation in universities, timely prevent and resolve risks from the origins, and ensure a healthy environment for students. Following the law of resolving public opinion, early prevention, early detection, and early resolution, educators attach great importance to the ideological and political education of college students, and maintain the clarity of the campus network environment.
