Research On Organization And Management Method Of Online Learning Resources And Learning Behavior Based On Knowledge Map

The emergence of online learning alleviates the lack and uneven distribution of high-quality teaching resources,and alleviates the contradiction of the unbalanced development of education.At present,online learning system is becoming more and more popular,playing a more and more important role in education,and putting forward higher requirements for its resource management.Most of the existing online learning systems use the hierarchical directory form based on syllabus to organize,manage,present and locate learning resources.However,there are some problems in using the above methods to manage resources,such as information overload,difficult to locate resources quickly,and simple linear way of resource organization.Information overload increases students'cognitive load,and it is difficult to locate resources quickly,which hinders students'efficient learning.Single type resources can not meet the differentiated needs of students.At the same time,browsing learning style and location-based navigation mode are very popular in recent years.Public map service can visually show the multiple relationships between geographical units and help users quickly locate the target geographical units,which has been widely used in daily life.Based on this,inspired by public map service,this paper proposes an online learning behavior and resource management method based on knowledge map.The two-dimensional plane is divided into polygons based on regions,and will be assigned to knowledge units representing different levels,and then polygons are further divided according to the resources contained in the knowledge points,and each polygon corresponds to a resource.The geo-spatial hierarchy of the map can be used to represent the hierarchical structure of knowledge points,and the display of different levels of information can be controlled by the map scale.At the same time,the multiple relationships between map elements can be used to reflect the close relationship between knowledge points,map browsing learning behavior is recorded and analyzed.It provides a new model for online learning resource management.Map positioning and retrieval make the whole learning process more efficient,novel and interesting,which increases the possibility of students' investment and persistence in online learning.This paper discussed the resource organization management and behavior storage management of online learning based on knowledge map,designed the corresponding teaching case,and verified the effectiveness of the method based on typical discipline management.The main research contents are as follows:(1)The related theories,construction strategies and application status of knowledge map was analyzed.It is summarized that the existing problems in resource management of online learning system include:it is difficult to retrieve and locate resources due to information overload,the form and content of resources are not rich enough,and there is only a single inclusion relationship between knowledge points.On this basis,combined with the advantages of public map services,this paper explored a new way of online learning resource management.(2)This paper put forward the management method of online learning resources based on map primitive division,integrated the knowledge map theory into the organization of online learning resources,defined an independent four-element structure to store knowledge units in a structured and unified format,constructed the knowledge system structure of the course,maps the bibliographic knowledge system structure to a two-dimensional map plane.On the basis of map primitives partition,resource area integration was realized,and finally a new resource association management based on knowledge map was realized.(3)A location-based learning behavior storage and management method was proposed to transform online learning behavior into map browsing activity.The storage structure of online learning behavior was constructed to record spatiotemporal operations based on map elements.Based on the map elements,we could visualize the learning behavior and results from different levels and angles,evaluate the current situation of learning,and reflect the blind and weak points of knowledge.(4)The typical online learning platform of knowledge map in the course of data structure was constructed,the effectiveness of the proposed method was tested.Taking the ranking chapter of data structure courses as a typical content,the knowledge map generation tool was constructed,and the resource packages with rich content and various forms were sorted and summarized.An online learning service based on knowledge map was released.An empirical study has been carried out among undergraduates and graduate students of Central China normal University,and the actual test has achieved good results.The experimental results show that knowledge map has the advantages of convenient operation,rapid positioning of resources,reflecting multiple relationships among knowledge points,and providing learning resources with rich forms and contents.Map-based positioning promotes efficient online learning,massive and diverse resources encourage learners to actively participate in online learning,and novel and habitual mapping services attract learners to invest more time.The following two points demonstrate the innovation of this paper:(1)An online learning resource organization and management method based on map elements is proposed,which integrates knowledge map theory into online learning resource organization.(2)A location-based learning behavior storage and management method is proposed,which transforms online learning behavior into map browsing activity,records and manages spatiotemporal operations based on map elements.In summary,inspired by the public map service,this paper converted the original hierarchical directory structure into a two-dimensional plane knowledge map,recorded and analyzed the learning behavior generated in the process of map browsing,and put forward an online learning behavior and resource management method based on knowledge map.This method embodies the integration of cartography and online learning,and provides new ideas for promoting online learning and providing personalized learning.
