Study On The Strategy Of Mathematical Graphics Processing Skills Training For Junior Middle School Students

"Graphics and Geometry" is one of the four major mathematical fields of the current "Compulsory Education Mathematics Curriculum Standards(2011 Edition)".Its core is to develop students' spatial concepts,geometric intuition and reasoning skills.Students' processing of graphics is their learning geometry.Based on the basics of graphics,teachers can only better organize teaching and achieve teaching goals based on the understanding of the status quo of students' mathematical graphics processing skills,thus cultivating students' spatial imagination and logical reasoning skills.At present,analyzing their problems in the processing of graphics and then proposing targeted training strategies is the key to developing students' mathematical graphics skills.Based on this,the research explores the following three aspects: 1 constructing the dimensional level of mathematical graphics processing skills,and preparing test papers according to this;2 investigating questionnaires and test volumes for students,analyzing the current status of graphic processing skills;3 According to the analysis results,targeted recommendations for training.This paper adopts literature analysis method,questionnaire survey method,interview method and case analysis method.Firstly,the mathematics graphics processing skills and related concepts are reviewed.With reference to Prof.Su Hongyu's analysis of the geometrical literacy evaluation dimension index “geometry skills”,On the basis of the definition of graphic processing skills,scholars use the skills of image recognition,expression,mapping,measurement,reasoning as the content of mathematical graphics processing skills,and each content dimension has different levels of division.Based on this,the research is determined.The test volume was compiled from the four dimensions of basicity,functionality,mobility,and comprehensiveness.Then,18 junior high school mathematics teachers and 240 students in the eighth grade were surveyed and interviewed,and the test paper was used.The school students' graphics processing skills are tested and the test results are analyzed from different angles.Through the analysis of the survey results,the status quo of the students' graphic processing skills is as follows: 1 The overall mathematics graphics processing skills of the students reach the mobility level;2 the average male students' average level is slightly higher than that of the female students;The skills in measurement are better,but the skills in expression,mapping,reasoning,etc.need to be further strengthened.Based on the comprehensive research results,it is found that the students' awareness of the use of geometric principles is not strong,the writing format of the proof is not in place,the mutual conversion of the three mathematical languages is difficult,and the logical thinking ability needs to be further strengthened.Therefore,the students' mathematical graphics processing skills need to be further Further improvement,combined with the three aspects of mapping,expression,mapping,measurement,reasoning and basic graphics,graphic transformation and triangle,congruent triangle,axis symmetry,put forward specific training suggestions.
