Study On Social Interaction Based On WeChat Public Platform

The advent of the Internet era is gradually changing learning and life of people.By comparison,the drawbacks of traditional education are emerging.In a traditional class,students only accept the teacher's content passively,lack of interaction with teachers and cooperative learning between classmates,which make no contribution to developing the ability to learn independently and the sense of teamwork.The vast sea of knowledge and constantly updated knowledge demands that we must break the space of autonomous learning,and learn to work collaboratively with others and study collaboratively in the vast ocean of knowledge.With the further influence of the Internet on education,universities are stepping in and combine the Internet with the classroom,which breaks the traditional teaching mode that students only sit in the classroom.As the result,the advantages of online learning are recognized by more and more learners and become the trend of the current learning style.This study uses the WeChat group as a tool for online interaction to study the social network structure of the interaction of learners in the WeChat group,and analyze the difference of knowledge construction level of different network location learners.First of all,the study use literature research to understand the deficiency of social interaction research in online learning platform,The entry point of this study was found that the WeChat public platform is used as an online learning environment,and the WeChat group is used as an online interactive tool to study the social network structure formed by the interaction of learners.Based on the course of ?Modern Education Technology?,the author used the WeChat public platform as an online interaction environment,designed and developed a WeChat public platform which serves the course of ?Modern Education Technology?.With the help of development technology,BBS module has been built in the platform,so that "Modern Education Technology" WeChat public platform has the function of social interaction.As well as,collected the interactive data generated by the learners in the WeChat group and used social network analysis to analyze interactive data.The social network structure of groups is studied through network density,agglomeration group,core-edge structure and centrality,finding that the core learners,the semi-marginal learners and the marginal learners,and analyze the differences between the three kinds of learners' interaction behaviors.At the same time,based on the content analysis coding system of Dr.Yongcheng Gan,and in combination with the actual situation,the content analysis framework of WeChat group was designed to code the content of the learners' posts,and analyze the differences of the core learners,the semi-marginal learners and the marginal learners' knowledge construction level.Through research,first,the network density of the "Modern Education Technology" WeChat group is not big,it shows that the communication between learners is not strong enough and the information is not good enough.There are three types of learners in the core,half edges and edges,and there are many small groups of these learners,small groups also interact with each other,but the connections are not strong either.Secondly,in the social interaction process of "Modern Education Technology" WeChat public platform,the social interaction between core learners and other learners is more active and frequent than that of semi-marginal learners and marginal learners.In the control capacity of information flow in the "Modern Education Technology" WeChat public platform,core learners are better than semi-marginal and marginal learners,and the number of core learners in the network "bridge" is much higher.Thirdly,most of the posts of learners in "Modern Education Technology" WeChat public platform stay at the lower level of knowledge construction,there are few learners who can reach the level of high-level knowledge construction,and the overall level of learners' knowledge construction is low.Finally,for the problem of the "Modern Education Technology" WeChat public platform,this paper proposes an improvement strategy from promoting interaction and enhancing knowledge construction,such as promote the interaction of edge learners,pay attention to the interaction quality of learners,and improve learners' knowledge construction level,etc.
