Studies On The Current Junior Middle School Mathematics Operation Capability Based On Core Competence Of Mathematics

The core competence of mathematics refers to the quality of mathematics thinking and the key ability required for personal life-long development and social development.Mathematical operation is one of the core qualities of mathematics.Junior middle school mathematics operation capability can lay the foundation for abstract arithmetic of high school while connecting intuitive algorithm of elementary school.Therefore,its research is of great significance.On the basis of precision machining strategies,meaningful learning theory,and constructivist theory,through literature method,survey method,interview method,this paper studies junior middle school mathematics competence.Twelve classes are selected from the research school,four classes at each grade,including two general classes and two intensive classes,respectively.Then,the paper conducts research from five aspects by compiling a examination paper for each grade,that is,the ability to master knowledge,the ability to use formulas,rules,and the ability to understand arithmetic meaning,the ability to choose reasonable methods,and the ability to extract question information.And from the interest in mathematical operation,five ability components of mathematical operation and the main reasons for mathematical operation errors in three dimensions to prepare a questionnaire for students.It is found from the investigation that in addition to the strong capabilities of mastering knowledge points,it is necessary to improve the other four abilities of ordinary students,especially the ability to extract question information,and their overall mathematics operation is poor.Excellent students have a good mastery of all abilities,but their ability to extract question information also needs attention.The main reasons include carelessness,insufficient attention to mathematical operations,neglect of the connection between old and new knowledge,and weak operational thinking ability.To solve above research questions,the paper proposes the following suggestions:establish the connection between the new and the old knowledge points,correct mathematics calculation attitude,cultivate the logical thinking ability,flexibly use formulas and rules,and create a teaching scenario in accordance with the cognitive structure of students.
