Cognitive Diagnosis Of High School Set Content Based On DINA Model

With the development of pedagogy,the disadvantage of traditional test gradually appears,and educators are no longer satisfied with the test of students' macro ability.In this context,cognitive diagnosis emerges as the times require.Compared with the traditional test,cognitive diagnosis not only pays attention to the students' achievement,but also pays attention to the students' internal cognitive state,which can diagnose the students' knowledge mastery state from the micro level,so as to provide better remedial measures for teachers and students.Based on the DINA model,this study first determines that the whole study is based on the cognitive diagnosis theory,all the theoretical basis and the final research conclusions are related to it After a series of studies,according to the diagnostic results,it provides teachers with remedial advice and students with remedial advice.This shows that the results of cognitive diagnosis can not only help teachers,but also help students.The specific research process and contents are as follows:Firstly,the cognitive attribute and hierarchical relation of the set content are determined,and the corresponding Q matrix is established to provide the theoretical basis for the compilation of the test volume;Secondly,in order to test the quality of the test paper,the test paper is pre-tested before the formal test,and the distinction,reliability and consistency index of the hierarchical relationship are analyzed;Lastly,we carry out large-scale measurement,collate the test data,analyze the data with the help of SPSS software and cognitive diagnosis platform(flexCDMS),get the diagnosis results,and put forward the teachers' teaching suggestions and students'learning suggestions.Based on the DINA model,247 high school students from a high school in Zhejiang Province were measured and analyzed.The results were as follows:(1)It is reasonable to establish the cognitive attribute and attribute hierarchy relation of mathematics set content in senior high school,which is the first prerequisite to obtain the correct diagnosis result;(2)The master mode of high school students is concentrated on the set content,and most of them belong to the ideal master mode;(3)Cognitive diagnosis can make up for the deficiency of traditional test and is more comprehensive than traditional test.
