A Comparative Study Of The Content Of "Algebraic Formula" In Mathematics Textbooks For Junior High Schools In China And Singapore

With the development of the world today,the improvement of the quality of education,and the advancement of the reform of the mathematics curriculum,mathematics educators are paying more and more attention to the study of mathematics textbooks.This paper takes the algebraic formula as the research content,compares and analyzes the junior high school mathematics textbooks between China and Singapore,and uses the methods of literature review,text analysis and comparative research to develop research questions from both macro and micro perspectives:(1)In terms of macroscopically,what is the difference between algebraic content distribution,textbook structure and style,and textbook writing order;(2)microscopically different from the "algebraic" knowledge structure,content presentation,illustrations,columns,exercises,The following conclusions are drawn:First of all,at the macro level,in the algebraic content distribution,the two editions of the textbooks use the "spiral" way to present algebraic content;in the overall structure and style structure of the textbook,the textbook of the human education edition reflects the learning of mathematics content and mathematics knowledge,DM The textbook emphasizes the teaching materials so that students can study mathematics independently and effectively,and it is convenient for students to learn and use the teaching materials themselves.In the order of textbook writing,the full multiplication and factorization of the PEP textbooks are presented in a linear manner,which helps the skilled use of the same type of knowledge.Mastery;the DM version of the textbooks presented in an alternating manner helps to strengthen the connection of different types of knowledge,and the overall grasp and flexible use of knowledge.Secondly,at the micro level,in the mathematics column,the textbooks of both countries pay attention to the reminding of important information in the process of knowledge presentation;pay attention to the methods and points of attention used in the process of solving the problem,embodying the students to “discover learning”"The concept of proactive exploration;in the presentation of computing rules,the algebraic formulas in the teaching materials of human education focus on the mastery of the operating law,and through the flexible use of the operating law to improve computing power,while the DM version of the textbook focuses on the learning of multiple representations.Use the graphic method to visually display the computingprocess to help students understand the knowledge.In the process of explaining the questions,the DM textbooks are usually accompanied by explanations along the process of solving problems.The content is mostly used in the process of solving problems,which is convenient for students to understand the steps of solving problems and deepen the mastery of knowledge.Finally,the author combines the research and analysis of the differences between the two textbooks,and draws some inspirations,and puts forward some suggestions for the preparation of junior high school mathematics textbooks in China:(1)pay attention to the mathematics learning process,use the multi-representation learning to manifest the mathematical thinking;(2)focus on training Students' ability to learn independently;(3)Emphasis on the ability to solve problems in actual situations;(4)Increase the content of cross multiplication and strengthen the connection of knowledge in middle and high schools;(5)Strengthen the integration of information technology and mathematics knowledge.
