A Teaching Design And Practice Study On Mathematical Modeling In Senior Middle School

Mathematics Curriculum Standards of General High School(2017)has proposed six core literacy of high school mathematics including mathematical modeling literacy.The key to the formation and commission of these core literacies is still classroom teaching.Therefore,how to design and practice the curriculum related to core literacy is a topic of great practical significance and research value.This paper aims at the classroom teaching of mathematical modeling and carries out the teaching design and practice research of mathematical modeling in high schools.Firstly,this paper studies and summarizes the domestic and foreign literatures on mathematical modeling teaching,and summarizes the development and current situation of mathematical modeling teaching in senior high schools at home and abroad.Secondly,in order to understand the current situation of mathematics modeling teaching in senior high schools,after repeated design and modification,a teacher-student questionnaire was developed,some students in two senior high schools in one place were investigated on the spot,and some first-line mathematics teachers in senior high schools were investigated online.The results show that :(1)senior high school students are obviously deficient in mathematical modeling knowledge and practice,but they have a positive attitude towards mathematical modeling course;(2)the mathematical modeling teaching ability of high school mathematics teachers needs to be improved urgently.The mathematical modeling teaching in high school is not fully implemented and is faced with many difficulties from top-level design to concrete implementation.Then,according to the survey results,combined with the examination of mathematical modeling in the college entrance examination and the relevant theories of teaching design,the basic principles and the general links of teaching design of mathematical modeling in senior high school are summarized.Finally,based on the basic principles and teaching links of mathematical modeling teaching design,a section of mathematical modeling teaching case is designed and put into practice.Through the analysis of the classroom record and the summary of the feedback from teachers and students after class,the case is optimized to make it a valuable reference case for the teaching design and practice of high school mathematics modeling.
