Model Design Of Digital Education Resource Service Based On Knowledge Map

In the information learning environment,the digital education resources are developing rapidly.It is not only the assistance of traditional learning,but also the continuation of lifelong education.Digital education resources enable learners to overcome the limitations of traditional education in time and space.They can learn autonomously or cooperatively according to the actual conditions.In the process of promoting learners' learning,digital education resources related services play an increasingly important role.It provides a variety of learning methods and comprehensive learning assistance for learners,which greatly improves the learning experience of the learners.However,with the growth and popularity of digital educational resources,there is still a gap between the digital education resource service and the learning needs of learners in terms of classified management of digital educational resources,learner's personal learning records,and the overall structure of fragmented knowledge.Through the literature review of digital education resources services and the analysis of the practical application of digital education resources services in the domestic and foreign open courses,it concludes that there are three major problems in digital education resource services: the lack of systematic integration of digital educational resources,the lack of organizational learning records(such as the learning notes)and the learner's academic situation have not been meticulously reflected.To improve the above problems,this paper introduces the concept of knowledge map in the digital educational resource service.Knowledge map enables visualization of knowledge resources and carriers in the organization,and form a knowledge network,shows the relationship between knowledge.Knowledge map also can establish intuitive and guided navigation for learners,it is helpful for learners to construct the whole cognition of knowledge points,and form a clear and well-structured knowledge pattern.Based on the characteristics of knowledge map,this paper designs a mode of digital education resource service.Through the node,the resources are aggregated by the knowledge points,which mainly include learning resources,personal notes,testing and expanding resources,and through the whole learning process of learning.In the process of resource aggregation,help learners establish a clear and complete knowledge network to improve the deficiency of digital education resources service in resource organization and knowledge construction.Taking HTML course as an example,the basic function of education resource service mode is realized by combing JavaScript and Google Maps API,and the development process,technology and content of this digital education are elaborated in detail.Later we do experience and evaluation on college student,adopt the form of questionnaire and interview to verify the feasibility of the service mode and the learners' degree of satisfaction,on the basis of the further optimization of the work.Digital education resource service based on knowledge map to build the new environment for resources learning,to improve the utilization rate of digital education resource and the learners' learning efficiency,for the durability of online learners' autonomous learning,knowledge internalization.It will provide some ideas for improving the quality of digital educational resource services and enhancing the learning outcomes of learners.
