Dynamic Online Interactive Learning Analysis Based On Social Presence And Social Network

Online learning has become one of the most popular distance learning methods.But online learning is basically realized in virtual environment interaction under the invisible filtered out some real social cues can feel the face,leading to interpersonal communication in computer mediated appears to lack of emotion,so that some learners produce loneliness,the emotional weariness in learning,serious or even drop out.It has been proved that social presence helps to reduce the loneliness of learners in the process of online learning.The relationship between social presence and interaction is very close,but the previous study of social presence can not reflect the dynamic process of interaction in the network course.And the parameters of the network structure analysis in the social network analysis can represent the characteristics of the interactive process in the network course.Therefore,this paper first constructs the static interaction model for the online interactive activities in a mixed classroom by means of adjacency matrix.On the basis of this model,the social presence measurement scale is used to measure the social on-the-spot score in the course of students' online interaction,the static social network analysis method is used to analyze the interactive network from different angles,and the students' knowledge level is analyzed with the content analysis method.Secondly,the dynamic analysis of the online interactive activities of the mixed course is carried out,based on the research demand,the dynamic interactive data analysis model is constructed,and the social presence score is measured from the model based on the social presence measurement scale,which is used to analyze the interaction of three periods by using social network analysis method,Based on the interactive activities of course participants in different periods,we use the IAM model to analyze the interactive content and a brief analysis of the interaction factors.At last,the analysis results of different stages are compared to reveal the change of interaction activity and its effect in the time development process.Through application practice,it is proved that the interactive data analysis model and analysis method are useful for the analysis of interactive data in online learning.Analysis of variance analysis and social network for a semester at different stages of the social telepresence shows that learner interaction frequency in the process of learning more,learners perceived social presence is stronger,thus confirming the online learning process,plays an important role in formation of interaction for the learners of social presence the.Learners perceive that the level of social presence is closely related to the depth of learners' interaction.Learners' perceived social presence is higher and their participation in interaction is deeper.
