Research On The Teaching Status And Strategies Of Elementary School Mathematics Infiltration Model Thinking

The mathematical model is the link that connects reality and mathematics,and the model idea is an important mathematical idea.Since "model thinking" was included in the ten core concepts,it has received a lot of attention in the field of education and academics.However,the basic education circle still pays little attention to model thinking,and the majority of front-line teachers are still in the stage of waiting and seeing or exploring the model thinking of cultivating primary school students.Therefore,it is very necessary to study the current situation of elementary school mathematics teachers infiltrating the model thinking in teaching,and to provide improvement strategies for the existing problems in teaching.Through studying a large number of related documents,the thesis gives the concept of model and model thinking in elementary school mathematics,discriminates related vocabulary,and uses mathematical modeling theory,mathematical theory,problem solving theory and constructivist theory as theoretical support.Based on this,the thesis takes the mathematics teaching in the second semester of elementary school as an example,and uses five methods to carry out research.Considering from the content of primary school mathematics PEP edition textbook,the paper sorted out the mathematics models of grades 4-6,combined with classroom case analysis and questionnaire surveys and interviews with primary school mathematics teachers in Hangzhou.Primary school mathematics teachers infiltrate the status quo of model thinking in actual teaching.According to the analysis of the status quo,the paper finds that the model idea has received increasing attention,its educational value has been recognized,and some teachers have been on the road of exploring the teaching of mathematical modeling.However,there are also some problems,mainly as follows:teachers have a little knowledge of model ideas;teachers have limited research on mathematical models;lack or weakness in permeating model ideas;teachers feel difficulties in modeling teaching;teachers' teaching experience and methods are insufficient;The actual modeling teaching effect is not ideal.Finally,the thesis considers from two levels,and proposes strategies for the model thinking of primary school mathematics teachers on how to train students in actual teaching.(1)Ideological level: Actively improve the teaching quality of model thinking;update the teaching concept of model thinking in time;accumulate and cultivate the teaching awareness of model thinking;adhere to the teaching spirit of loving research;explore the teaching design of infiltrating model thinking;strengthen communication modeling Classroom teaching experience.(2)Practical level:problem-careful design,establish the foundation of the model;link-natural connection,laying the model ladder;content-detailed content,enrich the connotation of the model;method-do everything possible to sublimate the soul of the model;Process-subtly,implicitly nurturing the idea of the model;application-inferring the truth of the model.The difference from similar previous studies is that the thesis uses a variety of methods such as text analysis,case analysis,questionnaire surveys and semi-structured interviews in the research process,and the research design highlights the idea of combining empirical analysis and qualitative analysis..The final thesis gives a wealth of teaching strategies,and the relevant conclusions can provide a certain reference value for elementary school mathematics educators and researchers when discussing model ideas or modeling teaching.
