Research On Teaching Of Solid Geometry In High School Under The Mathematical Core Literacy

Since the release of "General High School Mathematics Curriculum Standards(2017Edition)"(referred to as "New Curriculum Standards"),the core literacy of mathematics has received great attention in the research in recent years,and pay more attention to cultivate the core literacy of mathematics in the teaching of mathematics courses.With the reform of basic education in our country,the "New Curriculum Standards" proposes to implement the fundamental task of "cultivating people with morality" and "core literacy" as the core of education.Therefore,in the context of the new curriculum standard,how to implement and cultivate students' core literacy of mathematics in classroom teaching has become the core task of mathematics educators.Solid geometry is one of the key contents of high school mathematics teaching,and it is also the focus of the college entrance examination.The solid geometry knowledge is rich in content and it has extremely high educational research value.The content of solid geometry is highly abstract and logical.Therefore,solid geometry teaching occupies an important position in cultivating students' core qualities such as mathematical abstraction and logical reasoning.However,students' inadequate abilities such as spatial imagination,picture reading,drawing,and logical reasoning often make it difficult for students to learn,resulting in negative psychology and learning disabilities,making it even more difficult to cultivate students' core literacy in mathematics.This article aims to study the teaching strategies and teaching design of solid geometry under the background of the core literacy of mathematics,which not only enables students to master knowledge,but also cultivates students' core literacy of intuitive imagination,logical reasoning,and mathematical abstraction,guide students to master the mathematical thinking methods,and improve their ability to analyze and solve problems.The thesis mainly adopts the research methods of literature,survey,interview and case analysis.First,through the literature method to study the relevant literature,understand and summarize the research status of the core literacy of mathematics,the teaching status of solid geometry and the definition of related concepts,and at the same time obtain the theoretical support of the thesis research.Then,using the survey method to investigate the students with questionnaires and test papers,and at the same time conducted teaching interviews with front-line teachers,obtained relevant survey data and carefully analyzed them,further understood the current situation of solid geometry teaching and learning,and laid a foundation for the follow-up writing of the article basis.Finally,with the goal of implementing core literacy,based on literature research and survey results,the teaching principles and strategies of solid geometry under the core literacy of mathematics are proposed.And under the concept of core literacy of mathematics,the unit teaching design and two case teaching designs of solid geometry are carried out,and evaluate and reflect the teaching design.
