A Comparison Research Of The Geometric Content Offered In Senior Middle School “Mathematics Curriculum Standards(2017)” And “Mathematics Curriculum Standards(Experiment)”

"Ordinary high school mathematics curriculum standards(2017 edition)"(hereinafter referred to as "standards(2017 edition)")to perform began in autumn of2018,with the ordinary high school mathematics curriculum standard(experimental version)"(hereinafter referred to as the" standard(experimental edition)"),compared to the geometric structure,content,requirement,content,difficulty of content and so on are all great changes have taken place,these changes on high school math teacher is very good understanding of the standards(2017 edition).The overall problem of this thesis is that the standard(2017 edition)and the standard(experimental edition)are different from the geometric content.This problem can be broken down into three specific problems: What are the changes in the content structure of the geometric content in the standard(2017 edition)and the standard(experimental edition)? What is the change in content requirements? What is the change in content difficulty?This research mainly uses the comparison method of the combination of qualitative comparison and quantitative comparison method,qualitative method used in the two curriculum standard geometry content on the content structure,content,requirement of comparison,analysis of the standards(2017 edition)new characteristics of geometry content;The quantitative method is used to compare the degree of difficulty of the geometric content in the two editions of curriculum standard,and a mathematical model of "course difficulty" is applied.Compared with the standard(experimental edition),the standard(2017 edition)has the following changes.The requirements of geometric content are increased and decreased,and the intuitive imagination quality of geometry is highlighted.Geometric content on the difficulty of the rise and fall,but the overall difficulty level.In addition,it is also found in the research process that the standard(2017 edition)has the following characteristics: optimizing the course structure,selecting the course content and highlighting the main content;Increasing academic quality standards and examination proposition recommendations;More attention should be paid to the foundation of mathematics,and attention should be paid to the connection and connection between each study section.Finally,according to the research results and research conclusions,the author puts forward the following Suggestions on textbook compilation and teacher teachingwith the core of cultivating students' core mathematics literacy.1.In the aspect of textbook compilation :(1)the compilation of textbooks should attach importance to strengthening the cultivation of students' intuitive imagination quality;(2)the presentation of geometric content in the textbook should be rich and diverse;(3)the compilation of textbooks should take the development of students' core mathematics literacy as the objective.2.In terms of teaching :(1)teachers should delve deeply into the standard(2017 edition)to improve the professional quality of subjects;(2)teachers should pay attention to the cultivation of students' geometric intuition and imagination literacy in teaching;(3)teachers should guide students to understand the development process of geometry.
