Study On The Influence Of Social Network Structure On Knowledge Building Of College Students And Promotion Strategies In Micro-group

"Internet +" era,education and teaching reform in full swing,but our university teaching is still dominated by the traditional teaching methods.With the development of learning theory,the concept of people's knowledge learning is also changing.It is shifting from the transfer of knowledge to the knowledge building.The criterion of evaluation is no longer the knowledge and skills they own,but how to jointly create new knowledge.Therefore,in college teaching,how to make use of the communication tools widely used by college students in the era of "Internet +" and apply them to daily teaching to provide tools for further interaction between teachers and students,students and students to promote learners' knowledge building is of great significance.The way of knowledge building is learner's collaborative conversation in specific situations.Therefore,it is of great theoretical and practical significance to explore the influence of social network structure formed in knowledge building session on knowledge building from the perspective of human interaction.In view of this,this paper analyzes the social network structure and knowledge building of learners in micro-group by using social network analysis and content analysis methods to explore the impact of social network structure on knowledge building.The main work has the following three aspects:(1)Basic theoretical research.On the basis of consulting,combing and analyzing relevant data,this paper elaborates and summarizes the related theory of micro-group used in teaching research,social network structure and knowledge building,and clearly states the feasibility of using micro-group to assist classroom teaching in the course of “Qualitative research:Theory and Practice”,and confirms the social network structure analysis framework of this study.(2)The analysis of the social network structure in micro-group and the relationship between social network structure and knowledge building.This paper uses social network analysis method to analyze the social network structure of learner interaction in micro-group,and usescontent analysis method to encode the content of the discussion,and analyzes the proportion of posts in deep-level knowledge building from the whole,group and individual level.In the end,Statistical analysis is used to analyze the relationship between various factors of social network structure and deep-knowledge building.(3)Strategies to promote knowledge building in micro-group.Based on the analysis of the relationship between the various factors of social network structure and deep-knowledge building,this paper proposes the teaching strategies to promote the knowledge building in the micro-group from the perspective of social network.With the gradual progress of the above research work,the research has achieved the following research results:(1)The analysis framework of social network structure in this study is established,and knowledge building is divided into two levels:deep-knowledge building and shallow-knowledge building.They lay the foundation for the analysis of the relationship between various factors of social network structure and knowledge building.(2)This study analyzes the social network structure in micro-group and the relationship between various factors of social network structure and proportion of posts in deep-level knowledge building.The study finds that the overall network of the whole class is more closely connected,but the contact of each task group is different.In the whole class of the entire network,power is distributed unevenly,with core members and marginal participants.Members of the task groups or core members is the main body of the small cliques.The network density of learners,learners' out-degrees centrality,in-closeness centrality,betweeness centrality,the number of factions overlays,their core degrees and their effective scales affect the proportion of learners' deep-knowledge building.There are significant differences in the proportions of learners' deep-knowledge building in different block model positions,core and edge locations,structural holes and unstructured hole positions locations.(3)The research proposes the strategies of promoting knowledge building in micro-group.Through the above analysis,this paper puts forward the strategies of promoting deep-knowledge building from the aspects of teaching design,teaching practice and teaching evaluation.Due to the limited time and analytical ability of researchers,this study analyzes the relationship between social network structure and knowledge building.However,the knowledgebuilding of learners is also related to other factors.This study is only based on a case study of a micro-group,The generalization of the conclusion needs further study.
