Research On Design And Application Of Learning Resource Organization Model Based On Knowledge Map

With the development of Internet technology,learning resources have evolved from a single paper form to the current digital form.In order to meet the learning needs of learners in an adaptive environment,many experts and teachers have developed many learning resources,resulting in learners having lost their choice of learning resources.Faced with the problem of highly dispersed and disorderly development of learning resources,how to dynamically organize and filter "knowledge fragments"with discrete and heterogeneous features has important research significance for learners to provide personalized,intelligent,and efficient learning resources.At present,some experts and scholars have made some progress in the study of knowledge maps and resource organization methods.However,there are still some deficiencies,such as lack of timeliness,flexibility,and scalability,which make it difficult to meet the needs of today's big data environment.The need for learning resource organization.Based on the current problems,guided by the teaching theory of learning resource organization,a resource organization model based on knowledge map was proposed in this paper,so that the resource organization model conforms to the teaching rules.The main contents of the study include the following three aspects:(1)Construction of learning resource model based on knowledge mapThe learning resource model based on knowledge map was designed(this model includes learning resource module,learning resource representation module and map display module),and the mapping relationship between learning resource linked list and learning resource representation table was summarized.The learning resources were classified according to the learning process,and were extracted into micro-cells.Then,the IMS content packaging specification was used to form a link list of learning resources,and various learning resource components were packaged.Then,the micro-units and knowledge points were mapped together to show the logical relationship between knowledge points,so that learners can quickly locate the necessary knowledge points and related learning resources.Finally,a view of the map display layer was formed to construct a knowledge path for learners to navigate.(2)Design and Implementation of Learning Resource Management System Based on Knowledge MapThe model was applied to the learning resource management system.By analyzing the requirements of the resource management system based on the knowledge map,the main functions,processes and technical architecture of the system were designed and implemented.The main functions include a learning resource management content module,a learning resource management setting module,and a learning resource management tool module.Specifically,the learning resource management content module organizes the learning resources into the learning resource library,and the learning resource management setting module inputs,edits and associates the knowledge points and stores them in the knowledge base.The resource management tool module realizes the function of importing and exporting content packages and completes the backup of learning resources.(3)Application and analysis of learning resource organization model based on knowledge maps.In the end,the questionnaire was used to study the learner's learning effect and the quality of learning resource organization.and the background data of the system was used to analyze the learner's learning behavior.The experiment shows that the resource organization model based on knowledge map proposed in this paper has a promoting effect and can enhance learners' interest in learning and positivity,which validates the effectiveness of the model.
