Method and device for determining mastering degree of knowledge points and electronic equipment

Abstract

The invention provides a method and device for determining the mastering degree of knowledge points and electronic device.The method comprises the steps that based on questions in multiple pieces of test paper and answer data of a user for the questions in the multiple pieces of test paper, the mastering hierarchy of the user for knowledge points corresponding to the questions in each piece of test paper is determined; and inputting the mastering hierarchy of the knowledge points corresponding to the questions in each test paper into the deep knowledge tracking model, and determining the current mastering hierarchy of the user for the knowledge points based on an output result of the deep knowledge tracking model. According to the method and device for determining the mastering degree of the knowledge points and the electronic equipment provided by the embodiment of the invention, questions with a plurality of knowledge points can be processed, test papers with comprehensive questions with a plurality of knowledge points can be selected according to teaching requirements, the workload of teachers is reduced, and the teaching efficiency is improved. And the mastering degree, namely the current mastering degree, of the students on the knowledge points in a certain stage can be accurately and efficiently determined.

Description

technical field [0001] The present invention relates to the technical field of intelligent education, in particular to a method, device, electronic equipment and computer-readable storage medium for determining the mastery degree of knowledge points of students. Background technique [0002] In the online education system, it is usually possible to use the DKT (Deep Knowledge Tracing) model to determine whether students have mastered a certain topic or a certain knowledge point according to the given test parameters (question type, difficulty, knowledge points, etc.). Since this method can only identify whether a certain test question has been mastered by the student, if it is determined that the test question has been mastered by the student, it will be assumed that all the knowledge points involved in the question have been mastered by the student; or, if it is determined that the test question has not been mastered by the student , it defaults that none of the knowledge p...

Since this method can only identify whether a certain test question has been mastered by the student, if it is determined that the test question has been mastered by the student, it will be assumed that all the knowledge points involved in the question have been mastered by the student; or, if it is determined that the test question has not been mastered by the student , it defaults that none of the knowledge points involved in the question have been mastered by the students

Therefore, the results obtained according to this method are too absolute. If you want to determine whether a student has mastered a certain topic or a certain knowledge point, the teacher needs to manually customize the test paper for the student, that is, select a topic with only a single knowledge point, and use the DKT model to test the student's understanding of the subject. The mastery of knowledge points, although this can be done to obtain students' mastery of knowledge points, but it will only increase the teacher's workload, the efficiency of test papers is low, and only a single knowledge point with a relatively simple knowledge structure can be investigated

Therefore, this method is not suitable for the comprehensive test questions of multiple knowledge points involved in the teacher's teaching process. It is impossible to determine which knowledge points the students have mastered through the comprehensive test questions of multiple knowledge points, and it is also impossible to further determine that the students have mastered each knowledge point. to what extent
