Research On The Development And Cultivation Of The Concept Of Geometric Intuition In Elementary School

After the geometrical intuition was put forward as one of the ten core concepts in the "Compulsory Education Mathematics Curriculum Standards"(hereinafter referred to as the "Standards")in 2011,the academic community has paid more and more attention to it.This is due to geometrical intuition.It plays a very important role in cultivating students' mathematics literacy.Many scholars have made relevant researches in terms of its concept,connotation,form of expression,teaching value and application.The requirements of the Standards for pupils in terms of geometrical intuition are:no explicit requirements for geometrical intuition are given in the first semester,ie grades 1-3,and requirements for students in the second grade,ie grades 4-6,are to allow students to initially experience geometrical intuition.The role.There is very little research in the field of academia that specifically addresses the concept and connotation of the geometrical intuition in the primary school.Therefore,it will try to sort out the relevant descriptions of the existing geometry in the syllabus or curriculum standard and the study of it by scholars of various mathematics education circles.The definition of the concept of geometrical intuition in primary school and its connotation are given.Based on Van Hiele's theory of five levels of geometrical thinking and the five level theory of Hoffer's visualization ability,other scholars can use it to intuitively understand the relevant geometry.The division of the level gives the division of pupils' visually intuitive levels.The main contents of this article are:1.To sort out the concepts of geometrical intuition and its connotation,form of expression,teaching value,training strategy,intuition ability of geometry,division of geometrical intuitional level,etc.,trying to understand the concept of geometrical intuition and the status quo of its research from various perspectives.It provides the basis for the concept definition and horizontal division of the geometrical intuitiveness in primary school.2.Based on the above research,some suggestions and tactics are proposed for the cultivation of geometrical intuition in primary school mathematics teaching.
