Research On Developing Strategy Of Geometric Intuition Ability In Middle-grade Primary School Students

Geometric intuition is one of the core concepts of Mathematics Curriculum Standards for Compulsory Education(2011 edition).It is an important means to explore and solve mathematic problems in primary schools by means of graphic understanding and analysis of mathematics.Geometric intuition mainly refers to the use of graphics to describe and analyze problems.With the help of geometric intuition,complex mathematical problems can be simplified and visualized,which is helpful to explore solutions and predict results.Geometric intuition can help students understand intuitively and play an important role in the whole process of mathematics learning.Compared with the fifth and sixth grades,the students in the third and fourth grades are weak in the ability of comprehensive use,and the effect is not obvious,so they are often easily ignored.In the extensive reading of the literature on geometric intuition,it is found that there are many strategies to develop the students' ability of geometric intuition in primary school,and few of them pay special attention to the development status and analysis strategies of middle-grade primary school.The middle section is the beginning of plane graph and line graph.In the practical teaching,the teaching design of geometric intuition in the middle section of primary school is fragmentary and has not been studied systematically.In view of the above problems,the research methods of this paper include literature analysis,questionnaire survey,interview and experimental research.In this paper,the following problems are solved:(1)The theoretical basis and literature review of the training of geometric intuitive ability are summarized.(2)Investigate the current situation of students' geometric intuition ability and teachers' understanding and implementation of geometric intuition,and formulate preliminary training strategies.(3)According to the conclusion of the investigation and the training strategy,case design is carried out.This paper makes a multi-angle analysis of mathematics classroom from four aspects: textbook status,learning situation analysis,teaching process and teaching reflection.(4)The micro-teaching experimentwas carried out with experimental research method,and the training strategy of geometric intuition was revised and put forward to provide guidance for teachers to carry out intuitive teaching.Through the implementation of research and investigation,the combination of teaching practice and geometric intuition enables students to feel that mathematics,graphics and life are closely related,which stimulates students' interest in learning mathematics,mobilizes students' enthusiasm in learning mathematics,and significantly improves their achievements;through case design and experimental teaching research,students' geometric intuition is realized.Ability has been improved obviously and academic achievement has been improved to a great extent,which provides some new ideas for teachers.There are more perfect methods in teaching design.When teaching new knowledge,teachers will actively use geometric intuition to assist teaching,and also provide some ideas and methods for other teachers in geometric intuition teaching.
