The Deep Teaching Research Of Mathematics Geometry Concept In Elementary School

As a thinking form reflecting the essential attributes of geometric knowledge,geometric concept is the most basic element in the structure of geometric knowledge.Learning geometric concept is not only an important premise for students to further learn geometric knowledge,but also an important basis for the development of students’ mathematical thinking and core literacy.However,many primary school mathematics teachers find it difficult to realize the important value of geometric concept teaching.The teaching of geometric concept is often too superficial and formalized,and it is difficult to give play to the multiple values of geometric concept for students’ development.As a result,students’ learning of geometric concept is at the superficial level of memorization learning,and they cannot get rich development from the learning of geometric concept.Therefore,how to promote the in-depth teaching of the concept of geometric mathematics in primary schools,and give play to the multiple values of geometric concept for students’ development has become a topic worthy of in-depth discussion.The purpose of this study is to change the current situation of superficial teaching of mathematical geometric concepts in primary schools and explore the implementation strategies of in-depth teaching of mathematical geometric concepts in primary schools,in order to provide some references for the teaching of geometric concepts in primary school mathematics teachers.The research mainly adopts the literature research method,classroom observation method,interview method and action research method,from the theoretical interpretation,model construction and teaching practice of the in-depth teaching of primary school mathematical geometry concept exploration and research,on this basis to explore the primary school mathematical geometry concept in-depth teaching strategies.First of all,the connotation,typical characteristics and value of in-depth teaching of mathematics and geometry concept in primary schools are explained from a macroscopic level,and the connotation of in-depth teaching of mathematics and geometry concept in primary schools is clarified.Six typical characteristics and three important values of in-depth teaching of mathematics and geometry concept in primary schools are proposed.Second,the depth of elementary school mathematics geometric concepts teaching connotation and typical characteristics as the guide,through the observation of twelve geometry concept for primary school mathematics class,found that the current primary school mathematics geometric concepts superficial teaching problems in formal one-sided teaching objects,teaching circumstances,single islanding of teaching content and teaching form four aspects,The main reasons for the superficial teaching of geometric concept are the lack of full interpretation of curriculum standards,the outdated teaching concept of geometric concept and the lack of professional quality of teachers.Thirdly,based on the analysis of the current superficial teaching problems and causes of primary school mathematical geometry concept,combined with the connotation and typical characteristics of in-depth teaching of primary school mathematical geometry concept,the construction of the teaching mode of in-depth teaching of primary school mathematical geometry concept as an important guidance of action research on in-depth teaching of primary school mathematical geometry concept.From the function of guiding ideology,objectives,operational flow and implementation conditions of the four aspects in detail in this thesis,the teaching mode,put forward the elementary school mathematics teaching model of geometric concepts of five links operating processes,namely "depth interpretation,establish the teaching goal of" establishment situation,the former concept "" communication operation,form the concept of representation" and "abstract summary,define concepts "and" practice consolidating and migrating application concepts." Finally,the two geometric concepts of"quadrilateral" and "perimeter" in the first volume of grade three are selected as the main objects of teaching implementation.Through action research,the in-depth teaching mode of mathematical geometric concepts in primary schools is combined with specific teaching cases,and the relevant teaching experience obtained in action research is combined to put forward the implementation strategies of in-depth teaching of mathematical geometric concepts in primary schools from three aspects.That is to say,deeply interpret the teaching content,clarify the concept teaching direction,deeply carry out the teaching process,develop students’ higher-order thinking and optimize the teaching evaluation standard,based on students’ process experience.
