Research On Elementary Mathematics Class Teaching Strategies To Cultivate The Ability Of Geometric Intuitive

With the promulgation of the mathematics curriculum standard of full-time compulsory education(2011 Edition),geometry intuition,as one of the core words,has attracted more and more attention from experts,scholars and teachers.In order to explore how to better cultivate the geometric intuitive ability of primary school students in classroom teaching,this paper,based on the mathematics curriculum standards and related research results,combined with teaching cases,discusses the problems and training strategies in the cultivation of the geometric intuitive ability of primary school students,and tries to put forward teaching suggestions for the cultivation of the geometric intuitive ability of primary school students.In this paper,literature research,case analysis and observation are used to study the related concepts of geometric intuitive ability,the elements and development level of primary school students' geometric intuitive ability.According to its development law and teaching status,corresponding teaching suggestions are put forward.The main body of the article is divided into three parts.In the first part,the definition of related concepts and the traceability and evolution of geometric intuitive ability in curriculum standards.On the one hand,through the research results of experts and scholars on geometric intuitive ability from the aspects of concept evolution and evaluation model construction,the concept definition of geometric intuitive ability in this study is clear;on the other hand,based on the 2011 New Curriculum Standard and with reference to the interpretation of experts and scholars,the elements of geometric intuitive ability and the division of learning level are determined.The second part,combined with the classroom observation and typical teaching fragments during the practice,analyzes the current situation of geometry intuitive ability training.Find out the problems in classroom teaching.On the one hand,students' geometric intuitive ability is not in line with the requirements of the study section,and there is no deep problem awareness;on the other hand,the overall geometric teaching quality needs to be improved,and the concept of geometric intuitive and the application of teaching methods need to be further strengthened and penetrated.The third part,first of all,according to the rules of development about primary school students' geometric intuitive ability and combined with excellent teaching cases,analyzes the success of teaching,mining and refining the design concept and mathematical ideas in the case and upgrading them to the strategy of geometric intuitive ability training.Secondly,study the knowledge of teaching materials to locate the content of teaching materials suitable for cultivating students' geometric intuitive ability,and provide ideas for teachers to use the teaching materials of geometric intuitive ability in teaching.Finally,starting from the teachers themselves,through the study of teaching materials and curriculum standards,as well as participation in learning training to improve the teaching level of teachers' geometric intuition,and build an efficient training path for the ability of geometric intuition in classroom teaching.
