Investigation And Research On The Teaching Of "Figure And Geometry" In Primary School Mathematics

"graphics and geometry" to cultivate the students' thinking ability has an irreplaceable role,but due to geometric abstraction,make it become teachers to teach,students are difficult to learn.The reform of teaching method innovation is a key step to quickly implement the new curriculum goal.Past all of the geometry preliminary knowledge teaching is focused on understanding the morphological characteristics,calculation on the perimeter,area,volume,and practice after class is designed,which makes students have set back the ability to solve the problem of geometry.Curriculum expands the space and graphics knowledge scope,pay attention to cultivate students' space concept,enhance the experience,such as the students feel about things around,improve the operation and the ability to solve practical problems,put forward concrete Suggestions for space and graphic teaching,points out that "needs to pay attention to the student in the teaching to explore the questions about space and graphics in the real world;Need to pay attention to students through means such as observation,operation,reasoning gradually understanding the simple geometry and plane graph and the relationship of the shape,size and position of transformation;Need to pay attention to observe objects,understanding,making model,designs and other activities,develop the students' space conception ".These goals for space and graphic teaching reform puts forward new requirements.Therefore,how to quickly and accurately meet the new standard of teaching requirements,how to really improve students ability to ascend,we will constantly thinking,constantly explore.In this paper,questionnaire survey and interviews with teachers and students are used to investigate the current situation of "graphics and geometry" teaching in the second stage of primary school.Combined with the object and purpose of this study,the relevant questionnaire was compiled,and the existing problems in the teaching of "graphics and geometry" in the second stage of primary school were obtained through questionnaire survey,which provided the necessary basis for the optimization and improvement of teaching strategies.The second stage of primary school teachers and students were interviewed to understand the effect of teaching strategies and the existing problems.According to the surveyresults,this paper analyzes the shortcomings and main influencing factors in the teaching of "graphics and geometry",and puts forward some suggestions for the selection and improvement of teaching strategies.Finally,through the analysis of specific cases,the practical effectiveness of the research results is verified from the practical level.Through questionnaire survey and interviews with teachers and students,it is considered that the teaching of "figure and geometry" in the second stage of primary school needs to be further strengthened,and there are significant differences in the teaching of "figure and geometry" between different schools.The main problem in the teaching of "graphics and geometry" in the second stage of primary school is that teachers like to use the traditional teaching methods,and still spend most of their time in classroom teaching.There is little time for classroom operation activities.The teaching does not attach importance to cultivating students' interest in learning,and students lack good learning habits.Combined with the survey conclusion,this paper analyzes the main influencing factors of the teaching of "graphics and geometry" in the second stage of primary school from four dimensions of school,teacher,student and family.On the basis of the actual investigation and analysis of the influencing factors,this paper discusses the following aspects:(1)design teaching objectives according to students' geometric thinking level;(2)dynamic and life-oriented teaching contents;(3)using various teaching methods to cultivate students' space concept;(4)paying attention to variant processing of "graphics and geometry" exercises;(5)paying attention to students' core literacy The specific improvement strategies are put forward from five aspects,such as channel improvement,teaching evaluation mechanism,etc.
