Research On Junior Middle School Mathematics Teaching Based On Application Of Middle School Examination Function

Function is not only an important mathematical model to study the change of objective things,but also one of the important contents of junior high school mathematics.In recent years,the examination of students’ key abilities,such as operation ability,logical reasoning ability,comprehensive and application ability,has been gradually strengthened in Chengdu senior high school mathematics test.Especially in the function part,the examination of students shows the development trend from simple to complex,from single to comprehensive,from theory to practical application.The application ability of function plays an important role in the process of forming students’ mathematical core literacy,which directly affects students’ learning and growth in junior and senior high school.This research adopts statistical comparison method,text research method,testing method and interview method,taking the mathematics textbook of beinormal University as the research object,and makes statistics and arrangement of the setting and distribution of function application in the mathematics textbook of beinormal University.Taking the mathematics test paper of Chengdu middle school entrance examination from 2014 to 2019 as the research sample and starting point,it makes statistics and arrangement of function application problems in the test paper of Chengdu middle school entrance examination in the past six years On the basis of these statistical data,the paper compares and analyzes the similarities and differences of the above-mentioned papers in the application of functions.This paper analyzes and sums up the contents of the four typical functional application questions in Chengdu high school entrance examination combined with the mathematics textbook of Beijing Normal University.According to the analysis and induction of the four typical real questions of the middle school entrance examination,this paper uses the testmethod to test the function application ability of all the students in the experimental school of Tanghu middle school in Shuangliu District,Chengdu.Finally,combined with the above statistics,we actively communicate and discuss with the front-line teachers,and put forward effective function teaching suggestions.Based on the analysis of the mathematics examination function of chengdu institute of the application of the examination of form and content,according to the function of teaching contents of junior middle school stage,the function to the student ability to apply the cognitive level of the test result analysis,obtains the teaching in junior middle school mathematics teachers should enhance their function in the application of the consciousness,strengthen the cultivation of thinking ability students function,deeply implement the "four return to" the teaching of classroom teaching,and puts forward strengthening teacher training for high school period of mathematics educational research group,strengthen the collective lesson preparation,screening of classroom activities according to actual condition.
