Among the college students interviewed, 94.5% said they mainly use computers to surf the Internet, and 60.2% said they sometimes use mobile phones to surf the Internet. The convenience of the network promotes college students to make more convenient and extensive use of network resources. According to the investigation and analysis, the purpose of college students surfing the internet is mainly entertainment, taking into account communication and learning. Judging from the online learning behavior of college students, the main way of online learning is to collect information and materials. According to the survey data, the main ways for college students to learn through the Internet are consulting, downloading learning materials and searching for information, accounting for 37% and 33.9% respectively, and the proportion of students who choose to interact with teachers and classmates through the Internet is only 1 1.6%. It can be seen that college students pay more attention to using the network to obtain information and materials related to learning, but often ignore the interaction between teachers and students through the network. In fact, there are problems with e-learning. There is a lot of mixed information in the network, which is disorderly and random. When searching for information on the Internet, it is easy for people to fall into a situation where they have no choice or lose themselves, and therefore spend a lot of time. Some college students said that there are too few effective learning materials on the internet, long recognition time, insufficient information depth and lack of interaction; Some college students said that there are few in-depth materials for online majors and lack of interaction; At the same time, some network information is not credible, and even some netizens joke and spoof, which cannot be verified; Many college students also said that the knowledge gained from the Internet is scattered, one-sided, lacking in systematicness, and it is difficult to have an overall understanding of things. Therefore, it is urgent to integrate all kinds of online learning resources, establish a highly disciplined and professional learning website, enrich and popularize online resources of various courses, and provide a timely, convenient and comprehensive learning support service system by building an interactive online learning platform to provide environment and support for college students' online learning exchange and interaction. In addition, it is necessary to further improve college students' ability to identify network information, improve their skills in collecting, screening and sorting information, and enhance their ability to identify network information.
