Research On The Construction Of PLE Under The Perspective Of Knowledge Management

Under the perspective of knowledge management, the study to construct the PersonalLearning Environments (PLE) is instructed by Constructivism Learning theory and based onsummarizing and concluding PLE construction relevant study results in China and abroad.After taking a full consideration of the characteristics of personal meaning construction in thenetwork environment, such as the knowledge, intellectual,situationality and sociality, thisstudy analyzes the process of learners' knowledge construction online based on.theperspective of the combination of Activity Theory and Knowledge Management Besides,under the PLE model with the perspective of knowledge management, a PLE prototypesoftware have been developed by applying the integrated technology with```and testedactually.Under the perspective of knowledge management,The PLE model regards thetransformation of knowledge in the process of web-based learning as the main line, embodiesthe learners' subjectivity, the social and the collaborative nature of knowledge construction,the spiral construction of knowledge, the integrity of the learning process, PLE system'sintegration, integrative and openness and other characteristics. All of these can help learnersin the network environment get, manage, use and share learning resources, which promote thelearners to construct meaning.This article is composed of five parts including eight chapters, and each part of the maincontent is as follows:1.PLE related theories and literature reviewThis part consists of the introduction and the first chapter.The introduction part introduces the background of personal learning environmentconstruction and the relevant literature, and on this basis, expounds the study questions,studysignificance study and methods of this study.The first chapter expounds the related theory of PLE construction under the perspectiveof knowledge management, which is based on Constructivism Learning Theory, KnowledgeManagement Theory, Activity theory, tries hard to reflect the characteristics of the learners'learning in the network environment,such as knowledge construction, sociality,situationality, and openness, etc.2. The construction of the PLE model under the perspective of knowledge managementThis part consists of the second chapter.Regarding the transformation of the knowledge in the process of web-based learning asthe main line, the author divided the personal learning process that under the networkenvironment into the following four stages based on the different states of knowledge that thelearners acquire in the process of learning: knowledge acquisition, knowledge organization,knowledge using and knowledge sharing. The design of PLE model under the perspective of knowledge management has been constructed on this basis. And to discuss the interactionrelationship among the six elements (i.e. subject, object,tools,community,rules and thedivision of the work) of learning activities in the above four stages.3. The construction of the PLE modules under the perspective of knowledge managementThis part consists of chapter three, chapter four and chapter five.This part discusses the related issues of the acquirement of PLE learning resources, theorganization of PLE learning resources, the construction of PLE meaning and the knowledgesharing, which correspond to the four stages of knowledge transformation in detail. Theauthor constructs the PLE learning unit model, PLE personal learning repository model, PLEmeaning construction space model and PLEs community model, and further explains thetheories that the model constructed based on and the model function.4.System development and empirical researchThis part consists of the sixth chapter.According to the PLE model under the perspective of knowledge management and thesub models (i.e. the acquirement of learning resource, the organization of PLE learningresources, the construction of PLE meaning and the knowledge sharing), the author designsand develops the four prototype software, that is, PLE learning resources prototype software,PLE personal learning repository prototype software, PLE space prototype software, andPLEs community prototype website with the function of open API. And then introduces themain function and key technology of above four kinds of prototype software. Finally, takinglearning JAVA program with PLE used by graduate students as a case study, the authoranalyzes and verifies PLE system under the perspective of knowledge managementpreliminarily.5. Conclusion and prospectThe PLE system constructed under the perspective of knowledge management hasrelatively strong compatibility and integration, which can support the whole process of thelearners' learning in the network environment. System facilitates learners to acquire, manage,use and share learning resources. PLE meaning construction space is closely linked to PLEscommunity, which can promote learners' meaning construction.PLE individual learninglibrary which is based on SCORM standard helps learners preserve and use the learningresources. In addition, the follow-up studies mainly include the further discussions into theIEEE LOM metadata semantic function to strengthen the the reorganization of knowledgeof learning resources, knowledge clustering and intelligent recommendation between PLE andPLEs, which can further improve the PLE system function.
