Research On The Evolution Mechanism Of Social Cognitive Network Of Learning Community In Knowledge Forum

The learning community can create a collaborative learning environment for learners,effectively realizing learners from individual knowledge construction to group knowledge construction.This study conducts an empirical analysis of the learning community social cognitive evolution mechanism.The research design mainly uses the knowledge forum as the platform for students' computer collaborative learning.The learning community growth is divided into three stages.Different learning activities are designed according to the level of knowledge construction,and the activity data collected in different stages are analyzed to obtain the knowledge forum.The network of middle school students and students,knowledge and knowledge,and knowledge and content aggregation is based on the analysis of the network attributes of different stages,and the general characteristics of learning community social cognitive network evolution are obtained,and the development of learning community social cognitive network is proposed.Specific recommendations.The specific research work is as follows:First,study the social network structure of the community.Collect the activity data of learners in the knowledge forum at different stages,establish the relationship matrix,use Ucinet software to generate the interactive network of learners at different stages,and analyze the attributes such as network density and network centrality to obtain the learner interaction network structure.Evolutionary law.Second,learn the community's knowledge network research.Analyze the notes of the participants discussed at different stages,extract the discussion keywords,generate the co-word matrix,and use the matrix to transform into the dissimilar matrix,expand the lexical cluster analysis,form the network of keywords and topics at different stages,from the network nodes The connection thickness and the intermediate center degree are analyzed to obtain the evolution rule of the network structure of the learner's interactive content.Third,study the community's social cognitive network research.Establish a relationship matrix between students and topics at different stages,and integrate the matrix with social networks and knowledge networks to form a social cognitive network,analyze the network,and obtain evolution rules at different stages.Fourth,to promote the development of community social cognition network related recommendations,based on the results of the above analysis,put forward some suggestions for enriching the development of social cognition network in the process of students' online learning.The conclusions of this study are as follows:First,the frequency of learners' interactions has gradually increased,network intensiveness has been enhanced,the position of team leaders has gradually weakened in the group,rights have been dispersed,and the contribution of members of the group to knowledge has narrowed,and more members and team leaders have emerged.Master the resources within the group,control the flow of information,and independently disseminate and obtain information.Second,the perspectives and core themes discussed by learners at different stages are different.The perspectives of discussion are mainly from teachers and learning to teaching.The topics of discussion are the development of teachers' ability in the context of educational informatization,and the influence of digital resources on students' learning.Teaching case design,learning reflection and harvesting experience of digital resources.Third,the social cognition network of learners is gradually increasing,and the interaction between learners is more and more frequent.The knowledge content resources developed by the learners are also richer,and the learners with high social network attributes are presented as a whole.Its knowledge network also develops better features.Fourth,in the knowledge forum,to promote the better development of learners'social cognition network,it can be carried out from the following aspects.First,create a good collaborative learning atmosphere for learners,encourage students to actively participate in forum interactions,and secondly,promote students' integration of notes and provide students with strategies for writing notes.Finally,strengthen the supervision of students' learning activities and promote students' positive reflection on their own learning process.
