Research On The Design And Practice Of High School Mathematics Precision Teaching Based On The Big Data Of Jike

The development of education big data has brought new development opportunities for education.Under the current background,how to make rational and effective use of education big data and make it better used in classroom teaching has gradually become the focus of the research of experts and scholars in the teaching field and educators.As an important part of high school teaching,mathematics will produce a large number of educational data in the teaching process.How to use these educational data and tap its potential value to improve the quality of mathematics teaching has always been a difficult problem for mathematics educators.Jike big data,as an intelligent auxiliary teaching platform with the help of big data technology,normally collects process data to carry out a series of activities such as lesson preparation,teaching,testing and evaluation,provides technical support for improving teaching quality by using educational big data.This study selects Ningxia No.X middle school as the experimental school,aims to explore how to use the extreme class big data to realize the precision teaching of senior three mathematics,and improve the quality of teachers' teaching.On this basis,this study selects 22 mathematics teachers,4 senior three students and 2 parents of students in X Middle School to conduct questionnaire and interview,and analyzes the problems existing in the process of teachers and students using polar lesson in mathematics teaching.On this basis,the concept,theoretical basis and design principles of "precision teaching" are deeply analyzed.This paper selects "assure instructional design model" as the basic model reference,and on this basis,constructs a precise instructional design process based on extreme course big data,and carries out instructional design on this basis.The research results are put into practice in the new teaching of senior three mathematics and the paper evaluation course.Finally,the practical effect is analyzed to test the feasibility and effectiveness of this study.The results show that:first,through the use of big data,teachers can more accurately analyze students' learning situation,determine teaching objectives and teaching content,and students can more clearly understand their own learning situation.Second,the precision teaching of senior three mathematics based on the big data of Jike has significantly improved the teaching effect and promoted the realization of precision teaching.In the new teaching and examination paper evaluation,students'academic performance has been significantly improved.Third,after the teachers use the extreme course big data to help the marginal students accurately,the mathematics performance and weak knowledge of the marginal students have been significantly improved.In addition,due to the limitations of the researchers' energy and ability,as well as the epidemic situation and other reasons,this study also has some shortcomings,such as the lack of in-depth theoretical research,the small scope of investigation samples and the limitations of case analysis,which need further improvement and perfection in the future research.
