Research On The Creation Of Three-dimensional Geometric Situation In High School Based On Core Literacy

The core quality attaches great importance to reflecting students' subjectivity,and focuses on cultivating students' participation,exploration,innovation and good emotional experience.Solid geometry is a very important part of high school mathematics,which is mainly to cultivate students' core qualities such as intuitive imagination,logical reasoning and mathematical abstraction.Under this background,how to create a good teaching situation in the teaching process of solid geometry in high school and cultivate students' core quality of mathematics is very important.This paper mainly adopts the research method of combining theory and demonstration.Firstly,the literature research method has laid a good theoretical foundation for the research on the creation of three-dimensional geometry situation in high school under the core accomplishment.Secondly,the empirical research and analysis provide a reliable basis for the research.This paper is divided into five parts:The first part is literature review.Firstly,from the theoretical background and the practical background,this paper discusses the importance of mathematics core accomplishment,situational teaching and high school solid geometry,analyzes the current situation and main problems of students' learning solid geometry,and reveals the importance of this research.Secondly,the research significance,methods and domestic and foreign research review are discussed.The second part is the concept definition and theoretical research.Firstly,the concepts of situation teaching and mathematics core accomplishment are defined.Secondly,from the pedagogy,psychology and mathematics pedagogy three aspects of the theoretical demonstration,the purpose is to lay a good theoretical foundation for this paper.The third part is the investigation of the situation of the creation of solid geometry under the core accomplishment.Through the questionnaire survey,the author understood the current situation of situation creation in the real solid geometry classroom and analyzed the survey results,which laid a foundation for the follow-up strategy research.The fourth part mainly focuses on the strategy research of the three-dimensionalgeometry situation creation under the core accomplishment.Based on the above theoretical analysis and current situation investigation,six basic requirements and eight strategies for teaching situation creation of solid geometry are put forward.The fifth part is experimental research.Through the comparative study shows that the teaching of solid geometry in high school,appropriate creation of teaching situation,the effect of classroom teaching is optimized,to improve the students' interest in learning solid geometry,on students' logical reasoning and intuitive imagination,mathematical abstraction ability are of great help,core helps to cultivate the students' mathematics literacy.Through theoretical and practical research,this paper summarizes some basic requirements and strategies for the creation of solid geometry situation based on core accomplishment,and verifies its effectiveness through practice.It is hoped that the research of this paper can be helpful to the teaching of stereoscopic geometry and the cultivation of students' core qualities.
