| Teaching materials are the carrier of teaching activities,but also an important tool for curriculum reform,the quality of teaching materials is related to the effect of education reform,due to regional differences,there are a variety of teaching material versions in China.In order to comprehensively improve the overall quality of teaching materials,learn from and absorb the advantages of their respective teaching materials,and learn from the strengths of all,so as to promote the educational reform of basic mathematics courses,the comparative study of teaching materials has become a hot topic in educational reform.This paper takes the Jiangsu Education Press and the People Education Press of the High School Mathematics Textbook as the research object,takes the trigonometric function as the entry point,using methods such as text analysis and mathematical models,starts from the macro and micro aspects,compares the organization of the content of the two versions of Trigonometric functions and their specific conditions,and analyzes the similarities and characteristics of the two versions of the textbooks,aiming to provide some reference for the preparation of China’s future textbooks,improve the quality level of China’s textbook preparation,promote the construction of China’s mathematics textbooks,and promote the reform of basic education curriculum.The comparative study of this paper finds that the overall structure of the two versions of the textbook is roughly the same,both pay attention to the teaching of basic knowledge,both pay attention to the cultivation of students’ mathematical thinking and mathematical ability,both pay attention to the organic integration of mathematical culture,information technology and mathematics courses,and both pay attention to the consolidation and improvement of practice problems,but the two versions of the textbook have their own characteristics.At the macro level: the People Education Press has a clear meaning at the beginning,but the Jiangsu Education Press is better in the index,focusing on cultivating students’ symbolic awareness.In the introduction to the chapter,the People Education Press is straight to the point,while the Jiangsu Education Press is slightly procrastinating.In terms of column settings,the Jiangsu Education Press is relatively single,while the People Education Press is rich in types,focusing on the exploratory and problematic role of the side bar.In the chapter summary,the Jiangsu Education Press is too concise,while the People Education Press guides students to review the development process of knowledge with questions and further deepen their understanding of knowledge.In terms of mathematical culture,the materials of the People Education Press are diverse and involve a wider range.In terms of information technology,People Education Press is widely used and integrates information technology into classroom teaching.At the micro level: for the arrangement of trigonometric functions and the presentation of knowledge points,the Jiangsu Education Press is based on the cognitive structure of students,focusing on the connection and transfer between knowledge points,and the People Education Press focuses on the formation process of concepts and focuses on returning to the essence of concepts.In terms of example exercises,the Jiangsu Education Press sets up a large number of traditional question types,paying attention to the training and consolidation of basic knowledge,and the People Education Press sets a large number of open questions to cultivate students’ divergent thinking and innovative awareness.In terms of the difficulty of the example exercises,the background of the exercises in the Jiangsu Education Press is not close to life,and the difficulty is slightly higher than that of the People Education Press.In terms of mathematical core literacy,the Jiangsu Education Press focuses on cultivating logical reasoning and mathematical operation literacy,while the People Education Press focuses more on mathematical abstraction,intuitive imagination and mathematical modeling literacy,attaches importance to cultivating students’ mathematical literacy in various aspects,and pays attention to students’ comprehensive development. |
