Research On The Application Of Mathematical Modeling Thought In Junior High School Mathematics Teaching

With the gradual deepening of the new curriculum reform,mathematical modeling has gradually moved from behind the scenes to the front,and the idea of mathematical modeling has become one of the important ideas.Infiltrating the idea of mathematical modeling will become an important direction of the current reform of the mathematics curriculum,cultivating and developing mathematics for junior high school students Modeling literacy will also be an important goal of mathematics teaching.However,through investigation and research,it is shown that the current junior high school students' understanding of mathematical modeling is still relatively vague.Most of the students have not heard of mathematical modeling,and they still do not know what mathematical modeling is.Students' mathematical modeling literacy,what can be taught,and how to teach it has always troubled them.According to the above teaching situation,the key to solve the current mathematical modeling teaching is to propose a set of correct teaching theory guidance,establish reasonable teaching principles,and formulate effective teaching methods and teaching strategies.Based on the above analysis,this research is mainly divided into six chapters for discussion.The first chapter is the introduction part,which mainly explains the relevant background of this research,the significance of the research,as well as the content and thinking methods of the research;the second chapter is related to the The definition of the concept and the introduction of the theoretical basis provide the theoretical basis for the teaching strategy of the mathematical modeling idea.The third chapter is an investigation of the current situation of the application of the mathematical modeling idea in the mathematics teaching of junior high school.The understanding of mathematical modeling ideas,teachers' understanding of mathematical modeling ideas and their application in teaching,according to the survey results to analyze the reasons for its existence and establish the focus of research;the fourth chapter discusses in detail the mathematical modeling ideas in The application of mathematics in junior high school,according to the characteristics of the content of the textbook,combined with the cognitive ability of students and the current teaching situation,with the mathematics curriculum standards as the guiding ideology,the teaching principles and strategies for infiltrating the idea of mathematical modeling are proposed,and then according to the proposed teaching principles and strategies.Three typical teaching cases are listed on teaching strategies and principles.Finally,combining theory with practice,the proposed teaching strategies are put into teaching practice.The fifth chapter is the implementation and evaluation of mathematical modeling ideas in junior high school mathematics teaching.The specific implementation process in mathematics teaching,and then summarize and evaluate the implementation effect;the sixth chapter is the summary and reflection of this research.The research results show that the integration of mathematical modeling ideas into mathematics classroom teaching in junior high school is conducive to improving students' classroom participation,helping students to understand mathematical knowledge,change their learning attitudes,and improve mathematical literacy.The teaching of modeling thinking provides guidance on theoretical basis and reference for teaching practice.
