Application Of Knowledge Map In Fragmentation Learning

With the rapid development of science and technology,all kinds of intelligent mobile terminals are full of our learning life,and science and technology are changing our learning habits and rhythm.With the advent of a knowledge-based society led by a technology-based society,learning has become flexible and fragmented learning has infiltrated us.Fragmentation learning brings about fragmentation of learning methods,resources,time and space.Learning no longer occurs only in classrooms and libraries.Fragmentation learning brings some disadvantages while it is flexible and convenient: knowledge is fragmented in the learning process,and the connection between knowledge is very weak,and Cognitive load theory thinks that the capacity of human brain's short-term memory is very limited,which is very disadvantageous for learners to reconstruct fragmented knowledge in their cognitive structure.In this study,knowledge map is used to present the relationship between knowledge through knowledge map.Knowledge map has the functions of knowledge management and navigation,which enable learners to know the relationship between knowledge and the location of a knowledge in the knowledge network.After a lot of literature study,this paper explores the relevant methods,combs the application of knowledge map in fragmentation learning,and elaborates the research ideas from four stages: curriculum analysis,knowledge map construction,resource design and system development.In particular,the construction methods of curriculum knowledge map and personal knowledge map are studied.By calculating learner's learning behavior,the learner can know the learning progress and check the leaks and make up for the deficiencies in relevant knowledge points on the curriculum knowledge map,so as to provide guidance for learners to choose learning content independently and promote the construction of knowledge.
