Teaching Research On Solid Geometry Teaching In Senior High School From The Perspective Of Deep Learning

The features such as many contents and great difficulty are embodied in high school mathematics curriculum.Being a part of it,the solid geometry plays a vital role in cultivating students' core literacy.Due to the problems such as traditional classroom teaching methods and students' fear of difficulties,it causes the fragmentation of students' learning of solid geometry knowledge and the lack of attention to the cultivation of core literacy.Deep learning as an educational theory putting emphasis on knowledge,thinking and quality complies with the overall goal of implementing core quality.Therefore,the purpose of using the deep learning theory to the research of solid geometry by the author is to enrich the theoretical significance of theoretical research and guide the practical significance of geometry teaching.Firstly,the literature reading method is adopted in this thesis to consult and research the literature related to deep learning theory and solid geometry curriculum.The necessity and feasibility of applying deep learning theory to solid geometry teaching at the theoretical level are analyzed.Secondly,the forms of test paper,questionnaire and interview are used to carry out the investigation and analysis on the present status of students' deep learning of solid geometry and teachers' s deep teaching of solid geometry.Thirdly,the “judgment theorem of the perpendicularity of line and plane” is taken as an example to design the case and compare it with the traditional teaching case by combining with the deep learning theory in line with the results of investigation,test and interview.Finally,the concrete solid geometry teaching strategies from the perspective of deep learning theory are proposed in this thesis by making combination with the features of deep learning theory and solid geometry course content.According to what is mentioned above,the conclusions of this research mainly include the following three aspects:Firstly,it is found that the students' learning depth of solid geometry is not enough in line with the analysis of the test paper and questionnaire.The main problems of high school students in solid geometry learning at present contain the lack of learning confidence;the necessity to improve the ability of spatial imagination and logical reasoning;and the absence of critical thinking.Secondly,teachers lack deep teaching of solid geometry by combining with the interview.The main reflections can be seen in the teachers' lack of theoretical learning;the dependence on past teaching experience;and the lack of courage in innovative teaching.Thirdly,the concrete teaching strategies are proposed in this thesis by combining with the deep learning theory from three aspects such as the integrity of deep learning theory and mathematical knowledge,the systematicness of mathematical thinking and the implementation of mathematical core literacy.1.The solid geometry teaching strategy based on deep learning and integrity of mathematical knowledge(1)Construct an orderly geometric knowledge network by using students' existing experience(2)Summarize the geometric research routine and realize the positive transfer of knowledge2.The solid geometry teaching strategy based on deep learning and mathematical thinking systematicness(1)Carry out teaching based on general ideas and develop rational thinking(2)Carry out teaching based on inspiration and guidance and cultivate innovative spirit3.The solid geometry deep teaching strategy based on deep learning and improvement of mathematical core literacy(1)Focus on the generation of concepts and improve the core literacy of mathematical abstraction(2)Focus on the preciseness of reasoning and improve the core literacy of logical reasoning(3)Focus on the construction of situation and improve the core literacy of mathematical modeling(4)Integration information technology and improve the core literacy of intuitive imagination...
