Research On Mathematics Modeling Teaching In Middle School From The Perspective Of Core Competencies

Because of the emergence of computers,the relationship between mathematics and other industries is becoming more and more closely,and the mathematical technology of science and technology has become the trend of development.The mathematical model has set up an important channel to solve practical problems by using mathematical knowledge,and it is the basic means and important way of mathematical application.And with the "ordinary high school mathematics curriculum standards(2017 Edition)" promulgated,the urgent middle school mathematical modeling teaching,although researchers have more and more attention to the development of mathematical modeling in high school teaching in the middle school,but in fact the situation is not optimistic,the only part of the school will be dominant in the textbook of mathematical modeling--a case as a general function model,application to teaching and so on,be quite different and mathematical modeling requirements,students lose core competencies goals,so we have important significance to the teaching strategies of mathematical modeling in high school.Through reading the literature to understand the development of mathematical modeling and domestic teaching,understand the mathematical modeling teaching in the middle school through the questionnaire survey,based on learning theory,puts forward the teaching strategies of mathematical modeling in high school,from the selection of modeling and case adaptation,information technology integration,model classification and modeling teaching forms four aspects to elaborate how to carry out the teaching of mathematical modeling,and the combination of cultivating and improving students'mathematical competencies core teaching objectives in the teaching process.
