Analysis Of The Current Situation Of Solid Geometry Teaching And Learning In High School Under The Core Literacy

Core literacy is a hot topic in mathematics education in recent years,and it has attracted wide attention.Solid geometry is one of the important contents of high school mathematics.Its educational value is to improve axiomatic thinking on the basis of learning plane geometry,to train students' spatial imagination thinking,to apply mathematical language to transfer communication and intuitive perception,logical argumentation,and analysis and operation.Continuing on intermediate plane geometry,this section explores the relationship between points,lines,and planes in space.Guiding students to study this part efficiently,comprehensively and systematically can cultivate students' understanding of three-dimensional space,improve spatial imagination,and strengthen their understanding and application of mathematical language.However,from the point of view of the teaching process,the learning effect of this part of the content is not ideal.Therefore,from the perspective of cultivating core literacy,this paper analyzes the current situation of teaching and learning of solid geometry in high school.Hope to make a little contribution to high school mathematics teaching.This paper takes high school teachers and students as the research objects,mainly using the literature method and questionnaire survey method.Summarize the problems of teachers and students.Students need to enhance their learning emotions,build a three-dimensional geometric module mind map;change their learning methods,comprehend and master the ideas and research methods of open inquiry problems;develop the learning of reading and drawing,establishing mathematical models,and paying attention to processes and ideas.The teaching design of the solid geometry part of high school should include prerequisite elements,procedural elements and reflective elements.When designing,it is necessary to combine the inquiry-based classroom with the traditional classroom,create a teaching situation,infiltrate mathematical thinking,stimulate mathematical thinking,grasp the teaching process as a whole,and pay attention to driving students' problem-solving awareness.At the same time,a complete teaching design is designed with the example of "judgment of parallel line and plane".
