The Application Status And Teaching Strategy Of The Combination Of Number And Shape In Senior High School

Engels said: "mathematics is a science to study the quantitative relations and spatial forms in real life".Mathematics originates from the abstraction of the real world,closely linked with human life and social development,and carries the important thoughts and culture of human civilization.As a basic quality that everyone should have in modern society,mathematics literacy promotes the process of lifelong learning.Mathematics education bears the function of carrying out the basic task of moral education and developing quality education,helping students master mathematics knowledge,skills,ideas and methods,and playing an important role in improving students' mathematics literacy and forming correct outlook on life,values and the world.As one of the important mathematical thoughts,the thought of combination of numbers and shapes runs through the knowledge of each module in senior high school,which can effectively inspire students to think,help students grasp the essence of mathematical content,improve the efficiency of solving problems,and contribute to the formation and development of mathematical literacy.In the 2017 edition of general high school mathematics curriculum standard,it is pointed out that "through the learning of high school mathematics curriculum,students can improve the ability of combination of numbers and shapes".The idea of combination of numbers and shapes is an important way to develop students' core quality of intuitive imagination.Therefore,it is necessary to study the current situation of the application of the idea of the combination of numbers and shapes in senior high school.Based on reading the relevant literature,I summed up the literature about the connotation and development of the idea of the combination of numbers and shapes,and the problem-solving,teaching,information technology and investigation and research,and put forward the theoretical basis,the principle and solution of the idea of the combination of numbers and shapes,and made use of the questionnaire and interview method According to the investigation,the students find out the problems in teaching,and put forward the corresponding teaching strategies from four aspects: information technology,teaching materials,mathematical culture and problem solving types.
