Research On The Construction And Application Of Precision Teaching Mode Based On The Knowledge Graph Learning Platform

Since the end of the Spring and Autumn Period,after Confucius proposed "Teaching students in accordance with their aptitude",teaching students in accordance with their aptitude has always been the direction of educators’ efforts.In the 21 st century,the rapid development of modern technologies such as artificial intelligence,big data,and the Internet of Things has injected vitality into precision teaching.Precision teaching supported by information technology has changed from focusing only on students’ learning behaviors to focusing on students’ academic performance,learning process,and learning behavior,learning attitude and many other aspects.As an important subject at the basic education stage,mathematics is highly logical and abstract.Students need to clarify the logical relationship between the knowledge points and the knowledge points,and also need to accurately diagnose the problem to ensure the smooth learning and improvement of subsequent knowledge.Learning efficiency.The knowledge map learning platform integrates the mathematics subject knowledge map,the corresponding question bank and resources based on the knowledge points in the knowledge map,and the learner analysis model.It has the functions of learning diagnosis,teaching information storage,teacher-student interaction and so on.The entire precision teaching process provides strong support.Therefore,how to construct an accurate teaching model based on the knowledge graph learning platform and verify its effectiveness in junior high school mathematics teaching is an important research content of this research.This research analyzes the functions of the knowledge map learning platform and its effects on teachers and students,sorts out the precision teaching models supported by existing typical information technology,clarifies the core and key links of precision teaching,draws on its advantages and features,and learns the knowledge map.The function of the platform is appropriately transferred to build an accurate teaching model based on the knowledge map learning platform.The model is divided into three stages: accurate determination of teaching goals,accurate implementation of the teaching process,and summary and reflection.After the completion of the model construction,the quasi-experimental research method is used to conduct teaching practice in the experimental school to verify the effectiveness of the accurate teaching model based on the knowledge map learning platform.After the experiment is over,the results of the pre-and post-tests of the experimental class and the control class,the questionnaire data of the experimental class students on the effect of the implementation of the model,and the results of the teacher’s interview are analyzed.The results of data analysis show that the precision teaching model based on the knowledge graph learning platform can achieve precision and individualization of teaching,can significantly improve students’ mathematics learning performance,and increase the number of outstanding students and reduce the number of students with learning difficulties;student independence Learning ability,collaborative learning ability,self-exhibition ability,etc.have been improved;students’ attitudes towards mathematics learning have undergone positive changes;teachers’ teaching efficiency and students’ learning efficiency have been improved;teachers’ information teaching ability has been improved;knowledge Some functions of the atlas learning platform still need to be revised and improved.After the experiment,based on the results of data analysis,a summary and reflection were made,the accurate teaching mode based on the knowledge graph learning platform was revised,and the prospects for follow-up related research were put forward.
