Research On Evaluation Indicators And Methods Of Social Interaction Of Teachers Online Learning Community Based On Education Cloud Platform

As an important platform for knowledge exchange in the current information age,the role of online learning communities has become more and more important.Especially under the construction plan of "three links and two platforms",education cloud platform has gradually become an indispensable support and impetus for educational reform.Teachers' online training based on online learning environment is the focus of researchers' attention.The educational cloud platform embodies the interaction among members in online learning community,and becomes an important platform for teachers to conduct online learning.In order to effectively promote the education cloud platform to learn the social intercourse among the members of the community teachers online,and to improve the efficiency of the online interaction among the members of the community,it is necessary to analyze and study the interaction and interactive evaluation of the online learning community users on the platform of education cloud,and to explore the existing problems so as to facilitate the development of the education cloud platform.Targeted policy guidelines.This research takes the social network analysis method as the main research method,taking the Wuhan education cloud as the research platform,and selects the teacher users as the research object of the topic discussion module in the curriculum community.First,based on this topic,we discuss the interaction characteristics of modules,and build cloud interactive interaction model and interaction evaluation model.Secondly,the interactive evaluation of education cloud platform is carried out from two main lines.One is the interactive evaluation of node dimensions based on three aspects of macro,medium and micro,and the two is based on the interaction depth and the degree of interaction between the two aspects of the Interaction Evaluation of the nodes.Through the above study,it is found that:The structure of teacher interaction network in online learning community based on educational cloud is very loose,showing sparse features.Small density,less communication among members,more factions and obvious small groups,but small groups are only a few members,that is,only a few members have established closer ties,and the other members are still in the state of "Internet visitors";the core-edge structure is obvious,but in the core area Less active members in the field and more free members in the fringe area are not conducive to the stability of the community.The centrality of teacher users is generally low,there are few active members in the community,and the interactive contribution of the majority of teachers to the topic discussion of online course community is not enough;in addition,the online learning community interaction belongs to the shallow interaction.There are fewer interaction times between teachers and fewer topic reviewers,but there is less two-way interaction between posts initiator and commentator.However,the degree of interaction among the online learning community teachers is at a high level,and the teachers who participate in the online learning community interaction in the education cloud platform are relatively strong.
