Model Thought Into Junior Middle School Mathematics Teaching Research

Mathematics is an important part of human culture,and mathematical literacy is the basic literacy that every citizen in modern society should possess.In the "Mathematics Curriculum Standards for Compulsory Education(2011 Edition)",the model thought added ten core concepts for the first time and was proposed as the only mathematics thought,it should also be emphasized that modeling thinking is the basic way for students to experience and understand the relationship between mathematics and the outside world.Education researchers have been studying model thought for a long time,but the integration of model thought into mathematics classroom teaching in our country is still in the primary stage,and most of the research is about higher education,while the research on compulsory education stage is less.The teaching of plane geometry also contains the very important idea of model,On the basis of studying the integration of model ideas into teaching,this paper takes "circle",chapter 24,volume 1,grade9,PEP edition as an example to analyze.This paper adopts the literature research method,First of all,read the literature to get a certain understanding of the current situation of research model thought at home and abroad,Secondly,through questionnaire surveys and teacher interviews to understand the current situation of teaching front-line model thinking integrated into the classroom,Through the problems found above,This article focuses on analyzing the content of Chapter 24 of the PEP textbook from five perspectives of microscopic grasping of knowledge points.From the perspective of life,teaching,learning,instrumentalization and horizontal comparison,this paper studies how the textbook reflects the model thinking and how teachers can make good use of these materials to better convey the model thinking to students.Through after-class communication with students and teachers and reflection on the whole teaching process,the following teaching suggestions were obtained:(1)Pay attention to the analysis of teaching material content;(2)Pay attention to the "ground attachment" of the situation creation;(3)Pay attention to the inspiration of students;(4)Pay attention to summary and reflection.
