Practical Research On KST-based Learning Diagnosis Model In The Course Of University Computer Foundation

With the development of the times,as time goes on,people pay more and more attention to the people-oriented education concept and as time goes on also pay more attention to the personal development of students.In the National Education Conference^[1],Xi Jinping claimed that giving priority to the development of education and persisting in deepening education reform and innovation is the most vital thing.The Ministry of Education issued that"Opinions of the Ministry of Education on Accelerating the Construction of High-Level Undergraduate Education to Improve the Ability of Talent Cultivation",^[2]also pointed out that the mechanism of monitoring,evaluation and feedback of students'learning process should be improved.In traditional classroom teaching,due to the limited time and feedback information,it is difficult for teachers to achieve individualized teaching for individual differences of learners'.Improving the learning efficiency and quality of learners,in accordance with their aptitude and individualized teaching,is a challenge for education informatization and education reform.Based on the MOOC platform,this topic combines the teaching of the University's Computer Foundation course with our school to explore the practical research of the learning diagnosis model,which is based on the knowledge space theory in the the University's Computer Foundation course.This project has five chapters.The first chapter expounds the research background,research significance and content,analyzes the research status of teaching evaluation and cognitive diagnosis in the field of education,and discusses the framework of the whole paper.Chapter 2mainly explains the related concepts,theoretical foundations and algorithms involved in this topic.Chapter 3 introduces the design process of the learning evaluation strategy.On the basis of the teaching mode of the Computer Foundation course of our university,combined with the developmental evaluation,it analyzes the relationship between knowledge points and constructing the relationship tree of test questions.And also it analyzes all the possible answers,and judges the true knowledge state of each answer state,which is based on the guessing probability and the probability of error.According to the student's answer status,feedback the real knowledge status,according to the personal cognitivediagnosisreport,thestudentsconducttargeted learning,according to the personal cognitive diagnosis report,the teacher conducts overall counseling according to the overall knowledge status,and adopts appropriate teaching remedial measures.The fourth chapter analyzes the practical research of the KST-based learning diagnosis model in the University's Computer Foundation course,and summarizes the students'test scores and questionnaires.Chapter 5 summarizes the research results and shortcomings of this topic,and plans the follow-up research work.Practical research shows that,on the one hand,the KST-based learning diagnosis model can provide feedback information in time for students'learning,and students can conduct targeted learning,based on evaluation feedback,to improve learning effect.On the other hand,this study provides a certain theoretical basis and guidance for the study evaluation and teaching optimization of the University's Computer Foundation course.
