The Community of Inquiry Theoretical Model: A Research Paradigm for Online and Blended Learning

Using content analysis ， the author reviewed the development of the community of inquiry ( Col) theoretical model ， and explored a multidimensional deconstruction of the framework and elements of the Col. Utilizing the method of knowledge mapping visual analysis， the paper excavated the knowledge mapping of academic journals， research hotspots and frontier Col literature in order to understand the multi-dimensional connotations of the Col， to review the research status of the Col abroad， to explore the future research direction of the Col， and to provide the reference value for domestic online and blended learning researchers' academic criticism and research paradigm shift. The results show that the Col model is a dynamic and process-oriented effective teaching theory model in the field of online and blended learning， which consisted of three interdependent elements : cognitive presence ， social presence ， and teaching presence. The model is based on collaborative constructivism， takes collaborative construction learning and critical reflection dialogue as the implementation ideas ， and takes critical inquiry into meaningful learning and deep learning as the implementation path ， in order to cultivate the students' critical thinking， reflective thinking， and higher- order thinking. It shows that the number of citations in journals such as the Internet and Higher Education has increased year after year since 2000 ， which have become a major carrier for international research on Col research results. Research topics focus on the holistic study of Col model， especially the relationship between Col and other variables that can promote in-depth online learning， and the study of cognitive presence ， social presence ， teaching presence and the methodology of Col model， etc. Hot research topics include text-based asynchronous learning network and teaching presence research ， asynchronous learning network and design-based research ， Col and deep learning， Col and critical thinking， Col and study of learning strategies ， Col and education support ， virtual community and online presence and metacognitive study， teaching presence and learning effect ， metacognition and learning effect ， asynchronous learning network and cognitive load research ， social presence and learning peiformance research ， etc. The scholars， such as D. Randy Garrison， Terry Anderson， Peter Shea and their frontier literature still have significant influence in the field of the Col. Those scholars have formed an influential academic community related to Col research.
