Research On The Teaching Design Of Primary School Equations Based On Model Thought

Model thinking is one of the ten core concepts of elementary school mathematics.The teaching of elementary mathematics equations also contains a wealth of model ideas.This paper uses the model idea to guide the elementary school mathematics teacher to carry out the equation teaching as the research problem,and uses the literature method to analyze the current situation of the mathematics equation teaching in the primary school.The text analysis method is used to carry out the 4-6 grade textbook of the elementary school mathematics of Beijing Normal University.The analysis,combined with the existing problems,carried out the design of the mathematics equation teaching based on the model idea;the case design method was used to write the teaching plan about the knowledge of the equation;finally,through the interviews with the frontline teachers,combined with the opinions and related theories of the frontline teachers,The principles that should be followed in the implementation of the teaching plan and the problems that should be paid attention to are put forward.This topic aims to cultivate students’ model ideas through the teaching of elementary mathematics equations based on model ideas,and to provide students with reference and reference for flexible solutions to complex mathematical problems.This paper is mainly composed of six parts:The first part,the introduction.The research origin,significance and significance of the research,research ideas and methods are expounded.The related researches on model ideas and equation teaching at home and abroad are collated and reviewed.The model ideas and equation concepts are analyzed and the model ideas are defined.And the concept of equations.The second part analyzes the current situation of elementary school teaching and summarizes the problems existing in the current mathematics equation teaching: the teacher model is not completely understood;the teacher mainly adopts the teaching method in the teaching process;the student’s thinking is difficult to transition from arithmetic thinking to Algebraic thinking.The third part,based on the model idea,the design of mathematics equation teaching in primary school,this part is based on the current situation of mathematics equation teaching in primary school,the learner analysis,content analysis,target design,and then the method design: situational teaching method,experiential teaching method,Discover the teaching method.Finally,the process design is carried out: model preparation stage,model establishment stage,model solving stage,model verification stage and model feedback stage.The fourth part is based on the teaching design of the third part of the teaching plan for the equation.The three topics of "Expressing Numbers by Letters","Equation",and "Meeting Problems" are mainly selected.The design of the teaching plan is based on the theoretical framework of Chapter 2,adhering to the basic principles,methods and process design described in Chapter 2.The fifth part is based on the model idea of the design and evaluation of the mathematics equation teaching in primary school.This part mainly combines the evaluation opinions of the first-line teachers on the program,and expounds the principles that teachers should follow in the process of implementation and evaluation and the problems that should be paid attention to.
