| The comparative education research has become a hot field in education research.The article selects the Beijing Normal University Edition and the Qingdao edition as the research object,and makes a comparative study on the two aspects of the function content in the two edition of the textbook.The distribution of function content,the content of function knowledge points,the structure of function chapters.A comparison is made between the number of exercises and the difficulty of the problem.In the microcosmic,the comparison is made from the first function,the front map of the two function,the problem situation,the mathematical activity,the reading material,the number of examples and the difficulty.On the macro level,(1)in the chapter distribution,the contents of the two version of the textbook are the same.The teaching material function chapters of the Beijing Normal University edition are independent and clear,and the Qingdao edition textbooks have different function knowledge in one chapter.(2)the content of knowledge points in the textbooks of the Qingdao edition is more than that of the Beijing Normal University,mainly the knowledge points of grade seven and nine.More.(3)in the arrangement structure,the arrangement structure of the two edition of the textbook has made the frame clear and the knowledge content is outstanding.The two edition of the textbook all have mathematical activities column and reading material,the supplementary column of the BeijingNormal University Edition is relatively proper,and the Qingdao Edition is more column.(4)in the exercises,the total number of exercises of theBeijing Normal University Edition is less than that of the Qingdao edition,from "five dimension" From the perspective of comprehensive difficulty model,the two versions of textbooks emphasize more on mathematical cognition and operation,and the level of knowledge synthesis and reasoning needs to be improved.On the microcosmic point of view,(1)in the front of the chapter,the two version adopted the matching map and the realistic situation connected with the contents of this chapter.The edition of the Beijing Normal University is more focused on the introduction of the learning goal;the Qingdao edition has a simple topic and more emphasis on the summary and introduction of the knowledge of this chapter.(2)the problem situation is more focused on the introduction of the reality of life.The Qingdao edition pays more attention to the mathematical reality and pays more attention to the internal relations of the mathematical knowledge.(3)the mathematics activities of the Beijing Normal University are more and more important to enlighten the practical ability;the mathematics activities of the Qingdao edition are more important to enlighten the s ability of observing and logical thinking.(4)in example,The number of examples of Qingdao in the island edition is larger than that in the Beijing Normal University Edition.The difficulty of the two textbooks is quite same.Finally,based on the conclusions of the study,the main suggestions are given:(1)the edition of the Beijing normal university needs to maintain the integrity of a functional chapter.(2)the Qingdao edition needs to ensure the independence of the trigonometric function and the two part of the two function.(3)in the arrangement,the Qingdao edition needs to pay attention to the appropriate amount of supplementary contents.(4)in the exercises,the two version of the textbook needs to be noted.(5)the two version of the mathematical activity is not only limited to the thinking and hands-on of the textbook knowledge,but also can relate the thinking and the hands-on links with the real life.(6)the two version of the textbook can appropriately increase the introduction function of the geometric sketchpad and other modern tools to deepen the intuition on the nature of the function images.Understanding,the two edition of textbooks set up thematic inquiry activities in this area. |
