| The rapid development of online education has promoted learner-centered e-learning activities.In the process of online learning,the absence of "social attributes" leads to the anxiety and loneliness of learners,it not only affects the teaching effect of online courses,but also leads to a weakly-connected state between classroom instruction and online learning.Online presence can relieve the anxiety and loneliness of learners in the process of online learning and promote their deep learning.How to enhance learners' online presence is the key to improving the quality of online teaching.The thesis begins with the blended learning,taking learners' learning experience as the breakthrough,based on the analysis of online presence in online learning space and refering to the CoI inquiry community framework proposed by Garrison et al.Based on the theory of social learning,it also designs the TSELC online presence theoretical framework,analyzes the structural characteristics of online learning space in terms of online presence and the Implementation path of TSELC online presence theoretical framework.And then it carries out an empirical study through different cases.The purpose of the study is to solve the quasi separation state of learners in physical and psychological aspects through the construction of TSELC online presence theory framework,promote learners' social learning and enhance the effect of blended learning or online learning.Its specific contents include:1.To clarify the research status and research basis of online presence at home and abroad.The research uses the relevant literature of Web of Science and CNKI core database as data samples and the research approaches such as knowledge mapping,metrological analysis and qualitative analysis for the sake of Research Status,Hot Topics and Development Trends of online presence research by means of CiteSpace and other research tools.The thesis makes a review of the research in the basic theory,practical application,analysis of effect and technical support of online presence,aiming at making clearly frontier themes and future research direction of the online presence research,combining with the Enlightenment of the theory of social learning,relevance and social constructivism,the research basis of the construction of the theoretical framework of online telepresence.2.To Investigate the application status of online presence network learning space.The study samples 48 universities in L province and 254 provincial online open courses,combining with the current situation of online open courses in colleges and universities.The study also investigates the problems in the application of online open course from educators and learners.It not only analyzes the basic situation of educators and learners in individual learning,social learning,cognitive learning and influencing factors;but also summarizes the current open online course application in the formation of low order level,laying the practice foundation for the construction of online presence model.3.To Construct the TSELC online presence theory framework.On the basis of the theoretical analysis of online presence research at home and abroad,this thesis explores the relevant research results of the community framework based on CoI.The core of the model is the learning experience of the learners and the online presence is divided into five dimensions: Teaching Presence,Social Presence,Cognitive Presence,Emotional Presence,Learning Presence and so on.It builds TSCEL online presence theory framework by constructing relationship with design implementation path and application environment of the model with the help of blended learning,which combines with the current situation of colleges and Universities.4.To research on the application of TSELC online presence theory framework.The research chooses different types of courses such as " The editing and making of TV teaching materials "," Application of modern educational technology ","Network communication technology" and so on.The research samples the learners of different grades and specialties,adopting such appproaches as investigation,social network analysis,content analysis and experimental research.So the basic information of the learners,the evaluation of scale data and learning platform data are collected.From the learning process,teaching effectiveness,learning effect and other aspects,TSELC online presence theoretical framework research is applied to practice.The study adopts both pre-test and post-test to randomize the experiment through the contrast analysis between the experimental class and the control class,verifying the application effect of TSELC online presence theoretical framework.The results show that TSELC online presence theory framework improves the teaching effect of blended learning or online learning by focusing on learners' learning process.It extends the online telepresence from the "teaching society cognition" three dimensionality to the five dimension of "Teaching Society emotion learning cognition",emphasizing the promotion role of emotional presence and learning presence on learners' online learning.Emotional presence can release the negative emotions accumulated by the learners' online learning process,and effectively reduce the anxiety and loneliness of the learners in the online learning process.Learning presence is a regulator of online presence theoretical framework,promotimg learners' self-efficacy and self-regulation ability,and directly affectimg on learners' higher-order thinking ability.TSELC online presence theory framework contributes to the high-order interactive forms of critical thinking,promoting learners' deep and meaningful learning.Online presence-related elements have an important influence on the online learning,among which cognitive presence is the most significant.Higher order cognitive presence can reinforcement learning cohesive and self adjustment ability of learners to promote the transformation of margainal learners to core learners,and to realize the social learning of learners. |
