Research On The Application Of Polya’s Problem-Solving Theory In The Review Of Solid Geometry In The Third Year Of Senior High School

Mathematics has a very important status and significance both in the proportion of college entrance examination scores and in the cultivation of students’ core literacy.As an important part of high school mathematics knowledge system,solid geometry is a significant part of the high school mathematics knowledge system.The "General High School Curriculum Standards(2017 Edition)" emphasizes the development of students’ disciplinary core literacy,and the cultivation and improvement of students’ mathematical thinking ability.Under the background of the new college entrance examination,solid geometry is an important carrier for developing students’ logical reasoning literacy and mathematical abstraction literacy.It is particularly important for teachers to use more reasonable and efficient teaching methods to explain the knowledge of solid geometry.George Polya has deep attainments in many aspects,such as discovering and exploring laws in mathematics,and his problem-solving theory has very important guiding significance to the mathematics education and teaching of front-line teachers.This research will combine theory and practice to apply Polya’s problem-solving theory to the review of solid geometry in the third year of senior high school with the help of literature analysis,questionnaire survey and case analysis,in order to provide some help for the review of senior three.This dissertation is divided into six chapters:1.Introduction.The background,problems and significance of the research are expounded.2.Literature review.Including the study of solid geometry in the third year of senior high school review and the study of Polya’s problem-solving theory.3.Polya’s Problem-solving.4.Investigation and research.By investigating the methods and ideas applied by teachers and students in the review of solid geometry at this stage,it will lay the foundation for more scientific and efficient suggestions and methods to teachers.5.contrast experiment.According to the results of the investigation and research,a new classroom case was designed to carry out teaching experiments.The experiment found that the teaching mode of Polya and problem-solving theory was integrated into the teaching mode.6.Conclusion and enlightenment.The research conclusions and inspirations are given,and Polya’s problem-solving theory is rationally used in the review of students of the third year of senior high school.
