Research On The Teaching Strategy Of Plane Analytic Geometry In Senior Middle School Under The New Curriculum Standard

High school plane analytic geometry is the refinement and extension of function and equation knowledge in junior middle school.Learning plane analytic geometry well is of great significance to cultivate students' core mathematical literacy.However,students always have various problems in the process of learning.The Standard of Mathematics Course for Senior High School(2017 Edition)was formally promulgated in January 2018(hereinafter referred to as "17 Edition Course Standard"),which makes some changes in the teaching basis and reference standard of teachers in classroom teaching.Planar Analytical Geometry,as an important and difficult part of Senior High School Mathematics Course Standard,is the basis of the analysis of "17 Edition Course Standard".On the other hand,it is necessary to study the teaching of plane analytic geometry.Based on the above purposes,this paper investigates the teachers and students of Senior Two in Changchun Affiliated School of Beijing Normal University.The forms of investigation are questionnaire survey and interview survey.Through questionnaires,to understand the status quo of the students' study of plane analytic geometry in our school,and then to conduct random interviews with individual students,to further understand the students' learning situation,so that students can talk about their views on plane analytic geometry learning.Then,using the method of interview and investigation,we can understand the difficulties in the teaching of plane analytic geometry from the teacher' s point of view,and what kind of ideas we have for this part of the teaching.Then compare the new and old editions of the curriculum standards,find out the changes in the curriculum standards,based on the 17 editions of the curriculum standards,to analyze the current teaching work of plane analytic geometry mainly has the following four shortcomings to be solved urgently:first,students lack of interest,anxiety;second,weak computing ability,difficult knowledge transfer;third,ignoring pre-class preparation,avoiding questions in class;fourth,lack of mathematical culture,number.The ability of learning modeling is weak.In view of the problems found in the teaching of plane analytic geometry,some practical teaching strategies are put forward:(1)let mathematical literacy permeate the teaching from beginning to end;(2)change the role of high school mathematics teachers under the new curriculum standard;(3)highlight the importance of learning in teaching;(4)realize the deep integration of information technology and analytic geometry.The purpose of the above research is to provide teachers with reference for future education work,and to guide students to be interested in plane analytic geometry learning in high school,and to develop self-learning ability and innovative consciousness.The requirements and suggestions of 17 Edition Course Standard can be implemented effectively.It is hoped that it can play a positive role in promoting the reform of exercises teaching in textbooks for front-line mathematics teachers.
