Application Research Of Rule Space Model In Teaching Diagnosis Of Secondary Vocational Courses

Teaching diagnosis is a very important part of the teaching process and can provide support for teaching improvement.Teachers and students can discover the problems in teaching through teaching diagnosis,and then adjust the teaching methods.The diagnosis results can classify students into different “materials”.On this basis,teachers can “teaching” according to the characteristics of students to achieve the purpose of teaching students in accordance with their aptitude.The cognitive diagnosis model based on cognitive measurement theory can effectively measure,diagnose and evaluate the internal psychological mechanism of human beings,and is more used in the field of mathematics and English teaching diagnosis.In this paper,the cognitive diagnosis model-rule space model(RSM)is applied to the teaching diagnosis of vocational professional courses.First,based on the new generation of educational measurement theory,use the rule space model(RSM)to analyze the teaching content in the vocational curriculum,reveal the knowledge structure in the chapter-attributes and the hierarchical relationship between attributes,and then use the renovation method to compile a reasonable test Items,and apply corresponding attributes to characterize the items to be tested.Secondly,a rule space is established.The rule space model is used to analyze attributes and adjacency matrices,reachable matrices,event matrices,reduced event matrices,and typical attributes between attributes to determine the ideal response mode.Using the tool software to analyze the capability values ??and alarm rings of the ideal response mode,the resulting sequence couple is called a pure regular point in the rule space.According to the actual response of the actual subjects on the test items,it is judged that it is the corresponding ideal response mode.For the actual response mode of the participants,we use the Markov distance method.The method is to calculate the sequence of the actual response modes of the participants.The distance to all pure regular points,taking the pure regular point with the shortest distance,the subjects are classified as this pure regular point.This article selects the chapter of "IP Address" in "Computer Network Technology and Application" as a case study.Among the 463 subjects,24.3%,22.5%,and 19.0% of the subjects had the abilityvalues ??of 0.2832,-0.2698,and-0.1585,respectively.The subjects were found to have better mastery of four attributes such as binary,IP address,IP address classification and subnet mask,and the reasons and principles of subnetting and the subnetting examples were only available to a few subjects.In the interview,it can be seen that the effect of teachers and students on this new diagnostic method is relatively recognized.Students change from passive learning to active learning,and teachers can also improve the teaching methods for students' weak points.After using the rule space model for teaching diagnosis and interviewing teachers and students,the content and sequence of the chapter "IP Address",the form and means of student learning,and the teaching activities and methods were redesigned.Finally,the review "IP" was prepared.Address of the improvement lesson plan.
