Research On Design And Prototype Implementation Of Adaptive Learning Platform

The online learning platform breaks through the limitations of students' learning in time and space,and overcomes the many shortcomings of traditional teaching.However,the traditional e-learning platform provides students with “monotonous” learning resources,and students are learning in the same teaching method according to the same progress.These personality differences existed in each student objectively are seriously ignored,and education has become a pipeline of manufacturing “product”,which is not conducive to the cultivation of innovative talents.With the support of computer technology,personalized adaptive learning arises at the historic moment.Based on the adaptive learning and the content of “Modern Educational Technology Application”,this study focuses on the design and prototype implementation of adaptive learning platform.The main contents of the study include:1.Through the literature research method,the paper studies the domestic and foreign research on adaptive learning,and understands the current situation and development trend of adaptive learning research,and explores relevant theories and key technologies.2.This paper constructs an adaptive model to support bidirectional adaptation,which mainly includes the core modules of knowledge model,student model and presentation model.This adaptive model provides thebasic framework for the construction of adaptive learning platform.3.On the basis of the construction specifications of learning resources at home and abroad,the knowledge model is constructed from five aspects: chapter,section,knowledge points,learning objects and test questions.In order to provide “semantic” knowledge,so that the computer can “understand” the knowledge.Taking Chapter 6 “Animation Media Technology” in “Modern Educational Technology Application” as an Example,this study uses ontology technology and Protégé software to construct the knowledge model.4.This study constructs student model from five dimensions:learning style,cognitive level,learning goal,learning behavior and personal information.We use the ILS learning style scale to initialize the learning style,and the subjective Bayesian method was used to update the learning style dynamically.This paper puts forward the calculation rules of cognitive level,and the cognitive level is deduced from both test results and test time.5.In this study,we design and implement the prototype of adaptive learning platform.It mainly includes the design of the main function and the running process of the platform,database design and the implementation of the core functions of the platform.During the summary of research results,the author puts forward the prospects of this study at the same time,which include: Optimizing theadaptive model,knowledge model and student model;Improving the function of adaptive learning platform;Providing support of a more complete “user adaptation system”;Applying to the actual teaching and detecting learning results.
