An Empirical Study On Diagnosis Of Mathematics Learning In The Second Grade Of Primary School Based On Knowledge Map

The continuous development of science and technology promotes the improvement of education.Meanwhile,the arrival of artificial intelligence provides convenience for people to quickly access learning resources and also puts forward higher requirements for learners and teachers.Under the background of massive learning resources,the demand that teachers make sure to accurately find out the students' weak link in their study can't be met fully by the traditional teaching measurement on condition that students have already finished a certain amount of study resources.Mathematics plays an important role in elementary education which is difficult for students to understand and master because of its high abstraction and strict logic.At present,in the front-line teaching of mathematics,some teachers prefer to use the diagrams of knowledge structure to help students grasp knowledge points as a whole,from which we can only see the relationship among various knowledge points instead of controlling students' state upon the knowledge.Thus,its limitation is exposed.In view of the problems above,this paper elaborates the relevant theory of knowledge map and constructs the knowledge map of mathematics in the second grade of primary school by using the analysis method of ISM.According to the test data of students in Panlong District,the passing rate of each meta-knowledge point is marked on the knowledge map.Thus,difficult knowledge points for students are found out.Meanwhile,by using the relationship between these knowledge points in the map,the original knowledge points that result in the former difficulties are analyzed.At the same time,depending on the labels of test,not only are the reasons for the existence of these difficult knowledge points traced to its source but also some teaching advice are given combined with teachers' interference.As a result,the passing rate of students rises which manifests the rationality and effectiveness of the diagnostic method in terms of the second-grade students' study in maths based on the knowledge map.
