Design And Application Of Adaptive Learning System Based On Learners' Cognitive Level

As the field of artificial intelligence continues to infiltrate the education industry,online learning platforms that recommend and provide personalized learning resources to learners according to their different cognitive levels have gradually developed into one of the mainstreams in the development of modern education in my country today.Learners of different cognitive levels have different requirements for learning resources.Therefore,in the context of rapid development of technology,how to more accurately determine the corresponding cognitive level of learners has become a major problem for researchers.This paper constructs a learner model based on the learner's cognitive level based on the learner's mastery of knowledge points,and designs an adaptive learning function on the basis of this model,so as to provide learners with a model that meets their cognitive level and development needs.Adaptive learning system.The specific research work is as follows:(1)Construct a learner model based on cognitive level.Construct a learner-knowledge level matrix based on the results of the learner's test scores,understand the learner's mastery of knowledge points,and obtain the learner's cognitive level,thereby constructing a learner model based on the cognitive level.This model fully takes into account the learners' different levels of cognitive level of knowledge points,and can better meet the needs of learners for personalized learning.(2)The construction of an adaptive learning system based on the cognitive level of learners.Based on the above model,using SpringMVC,jQuery EasyUI,Mybatis and other framework technologies,from the perspective of practical applications,an adaptive learning system is designed and developed.The system has a rich question bank.Through tests,the learner's awareness of knowledge points is mastered,and suitable test questions are recommended from the question bank,providing learners with adaptive learning support services,and finally achieving personalized learning.(3)Application of adaptive learning system in teaching.In this study,students in the ninth grade chemistry class of junior high school were taken as the research objects.The second chapter of the ninth grade chemistry textbook was used as the specific knowledge content.The application effect of the system in practical learning was investigated through questionnaire survey and interview methods.Finally,it is concluded that the adaptive learning system has a certain auxiliary teaching effect.
