Research On The Design Of Junior Mathematics Living Teaching From The Perspective Of "Three Capability"

Elementary school to junior high school is not only the span of grades,but also the span of knowledge and difficulty.Abstract has become a new synonym for junior high school mathematics.The teaching model based on the textbook is outdated.Mathematics life teaching provides a new stage of mathematics classrooms.A new idea.However,traditional life-oriented teaching only focuses on the learning of mathematics knowledge,and ignores the cultivation of students' mathematical ability and mathematical literacy.How to use the existing advantages of mathematics life to help students acquire mathematics literacy and mathematics ability while learning mathematics knowledge? Professor Shi Ningzhong proposed that he would observe the real world with the eyes of mathematics,think about the real world with mathematical thinking,and describe the real world with the language of mathematics(referred to as " Three Capabilities ").From three short aspects,he closely integrated mathematics and life,from "seeing" to "thinking",and finally rising to "use".From the perspective of life,he attached importance to the cultivation of mathematics literacy and ability to provide students with a three-dimensional Methods of learning and applying mathematics.This article takes Professor Shi Ningzhong's " Three Capabilities " as the theoretical basis,and adopts the literature research method,text analysis method,questionnaire research method and case research method.First of all,based on the traditional junior middle school mathematics life-oriented teaching,the junior middle school mathematics life-oriented teaching under the " Three Capabilities " was introduced to demonstrate the feasibility and innovation of the thesis' s viewpoint.Secondly,the " Three Capabilities " and the teaching materials are analyzed and sorted out.Taking the " Three Capabilities " as the premise,the junior middle school life teaching is carried out in accordance with the four sections of mathematics teaching(number and algebra,graphics and geometry,probability and statistics,synthesis and practice).Feasibility Analysis.Regarding the related problems,the junior middle school mathematics teachers are taken as the survey object to conduct a questionnaire survey on the current situation of the mathematics classroom and the teaching effect,analyze and summarize the shortcomings existing in the junior middle school mathematics daily life teaching.The optimization methods of student learning and teacher teaching summarize the basic principles and strategies of teaching design with the " Three Capabilities " as the background.Finally,select the representative content from the four major sections of the teaching content to design the corresponding teaching case.Through the questionnaire survey,it was found that there are problems in classroom teaching that the students' mathematics ability cannot be better trained,teachers have insufficient understanding of the " Three Capabilities " and mathematics life-style teaching has not been implemented.Therefore,when teaching,teachers should choose from fun.Realistic examples,forming systematic knowledge theory and timely feedback,relying on the " Three Capabilities " to comprehensively train students.Teachers should correctly understand and attach importance to the " Three Capabilities " from the perspective of ideology,lead students to find the connection between mathematics and life,and grasp the classroom nodes Guide the opportunity,expand the practice to establish a mathematical model,pay attention to mathematical literacy and ability training,and improve the comprehensive quality of students.Under the guidance of teaching principles and teaching strategies,this article summarizes a streamlined instructional design plan to provide a new way of teaching mathematics life.Teaching cases that can be used for reference,looking for a three-dimensional training model for students,so that students can not only use existing life background to learn and apply new knowledge,but also cultivate mathematical literacy and mathematical ability in the process.
