The Study Of Mathematics And Life In The Two-way Primary School Mathematics Teaching

Mathematics is closely related to human development and social progress,with the rapid development of modern information technology,at the same time,in the field of mathematics in penetrating to the discipline also gradually permeated every corner of our life.People pay more and more attention to the problems of life,life mathematics and the mutual transformation between life and mathematics.At the same time,it has aroused the widespread concern of educational researchers,curriculum designers are also changing the previous phenomenon of disconnection between education and life,trying to effectively link up life and teaching content;In the current teaching practice,teachers also pay attention to the close relationship between mathematics and life,to practice the current social development and curriculum standards of mathematics education.In mathematics teaching,there is not only the teaching process of mathematics,but also the teaching content of life.Therefore,mathematics and life are not independent and separate,but an organic whole closely related and intermingled.Mathematics learning in primary school is the starting point of "math-life" bidirectional.Therefore,this paper attempts to study the teaching strategies and instructional design of mathematics in primary school from the perspective of "math-life" bidirectional.This paper adopts the method of literature research,through collecting and arranging the relevant materials of mathematical teaching,life-oriented teaching,and life-oriented teaching.On the basis of summarizing the related research achievements of predecessors,combining with the requirement of mathematics curriculum standard,this paper expounds the connotation of "math-life" bidirectional: mathematics originates from life,and returns to life,bidirectional is a circular reciprocation and the process of interaction.It also analyzes its theoretical basis from the following aspects:mathematics and life in mathematics teaching in curriculum standard,situational cognition theory,Piaget's cognitive development stage theory,Freudenthal mathematics education thought and so on.By further analyzing and summarizing the characteristics of "math-life" bidirectional,it is concluded that "math-life" bidirectional has four characteristics: authenticity,process,hierarchy and regression.According to these characteristics,this paper puts forward the specific requirements for the formulation of teaching objectives,the treatment of teaching contents and the implementation of teaching process,and gives the corresponding teaching strategies.First,according to the students' cognitive foundation and mathematical reality,and then combine the mathematics learning content,make the teaching goal,second,fully excavate the living material,reasonably deal with and scientifically reorganize the teaching content;The third is to create interesting and mathematical value of inquiry activities,students in this activity fully experienced the process of bidirectional.Finally,combined with the case study method,by studying the application of mathematics and life in the teaching of primary school,this paper selects the specific content of primary school mathematics,and analyzes the content from the perspective of "math-life" bidirectional.And design specific teaching cases.
