A Comparative Study Of The Content Of Trigonometric Functions In High School Mathematics Textbooks Of Hunan Education Edition And People ’s Education A Edition

In order to build a socialist modern education power and implement the fundamental task of moral education,the pace of education reform in China has never stopped.With the deepening of the new curriculum reform,many distinctive textbooks have been published throughout the country.As an important part of high school mathematics knowledge system,trigonometric function occupies a very important position in the process of high school mathematics learning.This thseis chooses to use a wide range of people’s education A version of the textbook and the distinctive characteristics of the Hunan education version of the textbook to compare the content structure of the trigonometric function part of the two versions of the textbook What are the similarities and differences? What are the differences in content difficulty? Through the comparative study of these problems,it provides reference for front-line teachers’ teaching and students’ learning.This thesis uses the literature analysis method,text analysis method,comparative analysis method,and uses the textbook content structure analysis framework to compare the style structure,content distribution,presentation,and example exercises of the two editions of textbooks.Using the textbook content difficulty analysis model,the text difficulty,the difficulty of example exercises and the comprehensive difficulty of textbook content of the two editions of textbooks are compared,and the following conclusions are obtained:1.In terms of style structure,the chapter structure of Hunan Education Edition and People’s Education A Edition textbooks is basically the same,but there are differences in the section structure.The column setting of the A version of the textbook is more abundant than that of the Hunan Education Edition,and the "mathematical culture" column is a major feature of the Hunan Education Edition textbook.In terms of content distribution,People’s Education Edition A textbooks pay more attention to the cohesion and systematicness of knowledge,and Hunan Education Edition pays more attention to details and comprehensiveness of knowledge.In terms of presentation,the A version of the people’s education is more flexible and diverse.In the setting of examples and exercises,the two editions of textbooks have rich types of examples and exercises,and the exercises are divided into three levels.The total number of examples and exercises in the trigonometric function content of the Hunan Education Edition textbook is greater than that of the People’s Education Edition A.The Hunan Education Edition focuses on the consolidation training of basic knowledge,and the People’s Education Edition A pays more attention to the application and expansion of knowledge.2.In terms of content difficulty,the difficulty of the text,the difficulty of the exercises,and the difficulty of the content of the trigonometric function of the Hunan Education Edition textbook are slightly higher than those of the People’s Education A Edition,but the difficulty of the examples of the People’s Education A Edition textbook is higher than that of the Hunan Education Edition.According to the above research conclusions,this thesis puts forward the following suggestions for the teaching of front-line teachers:(1)Carefully analyze textbooks and reasonably arrange teaching plans;(2)Carefully design the teaching process,effectively play the role of characteristic columns;(3)Enriching teaching methods and using information technology to assist teaching;(4)Play the exemplary role of examples,pay attention to the cultivation of students’ mathematical thinking;(5)Pay attention to the practice of application problems and open problems,and improve students’ mathematical modeling literacy;(6)Use the nature of the unit circle flexibly to organize teaching and help students explore new knowledge.
