Design And Implementation Of Micro-Lesson Resource Management System Based On Knowledge Map

The rapid development of the information age promoted the process of educational informationization, produced some new learning features, such as mobility, fragmentation, etc., in the meanwhile, learning resources proposed some new demands. Due to the segmentation of learning time and space and the diversification of media, learner’s attention stability reduced. In the past few decades, video media has been an important carrier to disseminating knowledge and sharing of knowledge, and plays an extremely important role. Under such a circumstance, micro-lesson appeared, which to a certain extent to solve the problem of learning resources, as well as the construction of information technology in education has injected new vitality.Micro-lesson, full use of the video features that easy to spread and vivid, as well as combinations of fragments of knowledge, open learning resources, knowledge sharing, and other modern learning characteristics, to meet the real needs of learners. In recent years, there are a lot of construction of micro-lesson resources, but the relevant research for micro-lesson organization and management is slightly less. Chaotic management and organization, will destroyed the development and construction of the micro-lesson resources, resulting in a waste of resources. In the aspect of knowledge management, knowledge map can effectively sort out the internal structure of knowledge, showing the implicit relationships, this can help people to effectively organize micro-lesson resources for learners and provide an excellent learning support and improve the micro-lesson resources use value. Therefore, how to use knowledge map to build a micro-lesson resource management system, it has become the focus of this research.This research, carry out by using literature research method, content analysis method and case studies method, etc., through analyze the construction principles and strategies of knowledge maps, organizational structure according to their characteristics complete knowledge map, using knowledge visualization techniques to draw subject knowledge map and build micro-lesson resources management system based on knowledge map, to provide better assistance to learning micro-lesson resources.This paper consists of five chapters:The first chapter mainly discusses the advantages and disadvantages of the learning method of current micro-lesson, and describes the origin of this research, put forward the problems and content should be researched, as well as methods used in the research. Next, analyzing and summarizing the research status at home and abroad in detail.The second chapter reviews the theoretical basis of this research, analyzing the concept of micro-lesson resources and knowledge maps, including the definition of terms, characteristics, types, applications, and define the concept of this research relates to the use of areas.Chapter III studies for the construction of knowledge map, begin with analyzing rationality for using the knowledge map to organize micro-lesson resources, analyzes the construction principle and organizational of knowledge map, and then discussion and description the display mode and method of knowledge map. After, propose a method that organization micro-lesson resources by thematic knowledge, to provide learners with the knowledge associated to help the learner to complete the construction of knowledge.The fourth chapter is the design process of micro-lesson resource management system based on the knowledge map. Analyzing system requirements and user, design system features according to construction method of the map knowledge, take science subject of junior school for example, published by Zhejiang Education Press, analysis curriculum and knowledge. Finally, discuss the key modules of the system should have, and described in detail.The fifth chapter is the implementation process of micro-lesson resource management system based on knowledge map. Through the decomposition of knowledge, made knowledge label property features, then draw micro-lesson resource maps. Using C# language and.NET technology, develop micro-lesson resource management system based on knowledge map, and explains key module implementation techniques and processes. Finally, testing and analysis the system, contrast design and content on preliminary, guarantee system availability and integrity features, as well as analysis the system application, described use of the system and related functions.Chapter VI is the summary of this paper. To sum up the content of this research, and reflect on the shortcomings of the research, than put forward what needs to be improved.
