Investigation And Research On The Mathematical Operation Ability Of Ninth Grade Students

In the educational background of the new curriculum reform,"arithmetic ability" has gradually become a common concern in the educational circle around the concept of qualityoriented education.This paper aims to understand the current situation of students’ mathematical ability,analyze the factors that affect students’ mathematical ability,and then put forward the strategies to improve students’ mathematical ability.Based on the theory of mathematical operation ability,this study uses literature method,test method,questionnaire method and interview method.In a middle school in Ganzhou City,154 students and four math teachers were selected as subjects.Based on Lin Chongdei’s theory of classification of mathematical operation ability,combined with the five knowledge dimensions of real number operation,with the comprehensive analysis of test paper,questionnaire survey and interview,this paper obtains the current situation of real number operation ability of grade 9students,analyzes the factors affecting the real number operation ability of Grade 9 students,and puts forward four suggestions.The results show that the real number arithmetic ability of all grade 9 students is not high on the whole,and there are great differences.Most of the students are at level 1 and Level 2 in real number arithmetic,while a small number are at Level 3.There are great differences among the knowledge dimensions of real arithmetic ability.The ninth grade students are the highest in rational number operation,followed by the square root of numbers,and the lowest in irrational number estimation.The subjective factors affecting the real number arithmetic ability of Grade 9 students are:(1)the cognitive structure of students;(2)Students’ interest and attitude towards computing;(3)Students’ computing habits.Objective factors include:(1)social environment background;(2)the comprehensive quality of school teachers;(3)Family environment.Based on this,four suggestions are put forward to improve the real number arithmetic ability of Grade 9 students:(1)improve the cognitive structure of students;(2)Stimulate students’ interest in mathematics;(3)Develop students’ computing habits;(4)Improve the comprehensive quality of teachers.
