Research On The Problems And Strategies In The Teaching And Learning Of Geometric Intuition In Elementary School

In this study,literature research,homework analysis,questionnaire survey and other research methods were used to investigate the problems and causes of primary school teachers' geometry intuitive teaching and students' geometry intuitive learning,and put forward corresponding teaching strategies.This study is divided into six chapters.The first chapter is to review the research status of geometric intuition at home and abroad by reading a large number of literature;Determine the research background and significance of this paper;Define the two core concepts of this paper: geometric intuition,the ability of geometric intuition of primary school students;Design this study.The second chapter is to sort out the teaching contents related to "geometric intuition" in the mathematics textbooks of grade 4-6 which will lay the foundation for the following research.The third chapter is to study the fifth grade students "geometric intuition" mistakes through homework analysis to explore the problems of students' geometric intuition ability,and to find that students mainly have weak perception of physical objects,lack of ability to identify graphics,weak ability to read graphics and so on.The fourth chapter is through the questionnaire survey and interview to understand the problems of geometry intuitive learning of primary school students and geometry intuitive teaching of teachers.The problems of teachers are as follows: in terms of sorting out,teachers' Geometric Literacy is not high,which is reflected in Teachers' insufficient understanding,mastering and application ability of geometric intuition,and the problems of students' ability of geometric intuition cannot be understood in depth;the problems of students are the lack of consciousness and ability of using several intuitive solutions.The fifth chapter is a summary of the problems found in the third and fourth chapter,and analyzes the reasons for the problems,in order to prepare for the targeted teaching strategies.The reasons for teachers' problems in geometry intuitive teaching are as follows: teachers have not established an effective bridge between the standard and the teaching materials,teachers have not established an effective link between the contents of the teaching materials,wrong questions and students' learning;the reasons for students' problems in geometry intuitive teaching are: Teachers' understanding of geometry intuitive,lack of mastery and application ability,and students' own learning.The sixth chapter puts forward the corresponding teaching strategies aiming at the problems existing in the primary school teachers' geometry intuitive teaching and students' geometry intuitive learning,so as to train the primary school students' geometry intuitive ability more systematically and effectively,and at the same time provide some reference for the mathematics teachers' geometry intuitive teaching.
