Research On Teaching Strategy Of Mathematical Modeling Activity Based On New Curriculum Standard

As a bridge between the mathematical world and the real world,mathematical modeling has gradually become a hot topic in the field of mathematics education in recent years.Mathematics curriculum reform in various countries and regions takes the formation of students' mathematical modeling thought and the cultivation of mathematical modeling ability as one of the goals of mathematics education.The focus of the new round of high school mathematics curriculum reform in China is to cultivate students'core literacy?Mathematics modeling is regarded as one of the six core qualities in the general high school mathematics curriculum standard(2017 Edition)?.At the same time,"mathematical modeling activities and mathematical inquiry activities" as a separate theme,together with "function","geometry and Algebra","probability and statistics" constitute the main content throughout the high school mathematics curriculum.From this,we can see that the "general high school mathematics curriculum standard(2017 Edition)" attaches great importance to "mathematical modeling activities and mathematical inquiry activities".In this paper,combined with their own practical work experience,first of all,through the questionnaire survey,interviews,literature research,interviews and other methods to investigate the front-line teachers and students,it is found that the current situation of mathematical modeling teaching is as follows:teachers and students are full of expectations for mathematical modeling teaching under the new curriculum standards,but lack of teaching strategy system to guide practical teaching.Through literature research,it is found that the theoretical basis of mathematical modeling teaching strategy research under the new curriculum standard is weak,which is not enough to support the current modeling teaching.Therefore,based on constructivism learning theory,metacognition theory and humanism,combined with the specific requirements of the new curriculum standard for modeling teaching,this paper puts forward the teaching strategies of mathematical modeling from three parts:before class,in class and after class.Finally,the case analysis method is used to analyze the cases in the appendix of the new curriculum standard and the cases in the new teaching materials,so as to provide reference for high school mathematical modeling teaching.
