Research On Construction And Application Of Multi-level Scoring Rules Space Model

The collision of education and information technology has brought new development opportunities to the education field.With the surge of this wave,the trend of personalized teaching has gradually attracted people's attention.At this stage,cognitive diagnosis can better serve personalized teaching and improve the degree of personalized teaching.The rule space model as a method in cognitive diagnosis can effectively diagnose the knowledge structure of students,but the current 0-1 scoring method of the rule space model can only obtain two extreme diagnosis results,although the method can give students The results of the knowledge state diagnosis,but at this stage can not meet the needs of education,can not make a more accurate evaluation of the degree of knowledge of students.In order to solve this problem,this paper constructs a multi-level scoring rule space model method based on the rule space model 0-1 scoring method.Extending the 0-1 scoring method to multiple levels,the diagnostic results are listed as multiple options,increasing the accuracy of the diagnostic results.This method first introduces the idea of multi-level difficulty calibration.The idea is to divide the difficulty range of the test questions according to the difficulty coefficient of the test questions.Based on this,the degree of knowledge mastery is graded.After the difficulty of the test questions is determined,the experts prepare the questions according to the level.Then use the adaptive answer process to enable students to complete the test efficiently,and at this stage focus on the strategy of pushing the test questions.Finally,the multi-level scoring strategy is used to realize the grading diagnosis of the students' knowledge structure,and the students' grading diagnosis report is obtained.At this stage,the students' knowledge status needs to be diagnosed first,and whether the students' cognitive attributes have correct answers are diagnosed.Then,in judging the item level in the cognitive attribute,the student's ability level is obtained,and finally the student's multi-level score cognitive diagnosis result is obtained.In order to verify whether the method can achieve the above required effects in the actual teaching,the research also carried out the teaching design based on the method,so as to be applied in practical teaching.The teaching design mainly includes three parts: preparation before cognitive diagnosis,implementation of multi-level diagnosis and remedial learning after class.It is applied to the practical application of "Computer Network Foundation" to carry out classroom teaching application.Finally,it analyzes and evaluates the four aspects of diagnostic accuracy,learning effect,satisfaction survey and teacher feedback.The experimental data shows that the method can accurately diagnose the mastery of the students' knowledge state,help students discover their own knowledge defects in time,provide a more accurate basis for remedial teaching,and ultimately improve the students' learning effect.The results of the survey showed that students participating in the experiment generally believed that the teaching model was easier and more efficient than the traditional classroom.Thereby effectively improving the effect of personalized teaching and improving the learning efficiency of students.
