A Comparative Study Of The Lines Of The High School Mathematics Textbooks And The Part Of The Equations

In the process of mathematics curriculum reform,the “one standard and multiple books” textbook writing policy has created five sets of high school mathematics textbooks with styles and characteristics.The multi-version textbooks provide teachers and students with more abundant teaching resources.Although the mathematics textbooks of various editions strive to reflect the requirements of the curriculum standards for textbooks in writing,due to the differences in the experience of the writers and the differences in the understanding of the curriculum standards,the textbooks have great differences in the overall thinking and layout system.After sorting out the relevant literature,it is found that there are many researches on the A textbooks of the People’s Education,the Jiangsu Education Edition,and the Beijing Normal University Edition mathematics textbooks.Usually,the knowledge system or a certain concept is comparatively analyzed,but there are few comparative studies on the chapters.Therefore,the author selects the line of the three versions of the textbook and compares the contents of the equation for comparison analysis.This study compares the macroscopic and microscopic aspects.The macroscopic level includes the overall characteristics of textbooks,the selection of lines and equations,the arrangement of lines and equations,and the overall aim of grasping the characteristics of the three versions of textbooks.The column setting of the content of the equation,the presentation of the core elements,the examples,and the exercises are compared at the micro level,and the knowledge structure and thinking methods contained in the textbook are deeply studied.Finally,combined with the results of comparative research,the teachers provide reference for the optimization of instructional design based on textbooks.The study found that the cover design of the three edition textbooks is different,but the order of layout is almost the same;overall,the order of the lines of the Jiangsu Normal University and the Beijing Normal University is basically the same.Through micro-comparison,it is found that the three editions of textbooks have more similarities in column setting,paying attention to the introduction of problems and providing students with space for thinking;the exercises in the Beijing Normal University are not difficult in all factors,and the other two The textbooks are quite different.Three suggestions for teachers’ use of textbooks are made: integrating curriculum resources to form a teaching model;infiltrating mathematics culture and taking into account information technology;focusing on the essence of mathematics and focusing on knowledge application.It is hoped that this study can provide ideas for the comparative study of mathematics textbooks,and provide reference for teachers to teach the content of lines and equations.
