Research On Solid Geometry Teaching Based On The Core Literacy Of Intuitive Imaginatio

The ordinary high school mathematics curriculum standard(2017)(hereinafter referred to as the curriculum standard(2017))condenses six core mathematical qualities.Among them,the intuitive imagination quality is very important for students to find,ask,analyze and solve problems,which helps to construct students’ abstract structure and form mathematical intuition.High school solid geometry is an important part of cultivating students’ visual imagination core literacy.This paper aims to explore the effective methods to cultivate students’ visual imagination literacy in solid geometry teaching.Firstly,this paper introduces the research background,research content,research status and research significance,and summarizes the research ideas and research methods.Taking constructivist learning theory,Friedenthal mathematics education theory,van Hill geometric thinking level theory and curriculum standard(2017)as the theoretical basis of this study.In order to understand the current situation of solid geometry teaching based on intuitive imagination literacy,this paper designs a student questionnaire and a teacher questionnaire,and interviews several teachers.According to the analysis of data and interviews,the problems existing in the teaching of solid geometry based on the core literacy of intuitive imagination are obtained.In view of the existing problems,this paper puts forward five teaching suggestions: first,the educational theory teachers should be strengthened;Second,we advocate the use of information technology in geometry teaching;Third,we advocate some examples should be used skillfully for visual display;Fourth,the efficiency for students should be improved;Fifth,teachers should do a good job in after-school reflection.Finally,according to our suggestions and the teaching design theory,we give the Teaching Design Cases for "visual diagram of three-dimensional graphics" and "determination of the perpendicularity of straight line and plane",we also summarize and evaluate the teaching effects.
