A Comparative Study Of The Probability Content Of Two Editions Of Compulsory Mathematics Textbooks For Senior High School

As an important resource for realizing the curriculum objectives and implementing teaching,the analysis and comparison of teaching materials are the breakthrough point and breakthrough point for carrying out teaching activities and compiling new teaching materials.Probability,as an important part of high school mathematics textbooks,is different from the traditional mathematics content such as function,geometry,algebra and so on.It takes random phenomena as the research object,and provides people with the thinking mode of understanding the objective world and the method of solving problems from the perspective of uncertainty.It occupies an important position in high school curriculum,but its development in secondary school textbooks has also affected the smooth development of teaching activities.Therefore,it is necessary to compare the probability content of different versions of textbooks,which not only helps teachers understand and learn new textbooks,better carry out teaching reform,but also provides reference for future revision of textbooks.This paper selects the probability content of the compulsory textbooks of New People ' s Education Press A and New Beijing Normal University Press,adopts the methods of literature analysis,interpretation structure model,content analysis and comparative research,and based on the revised comprehensive difficulty model of Professor Wang Jianpan and Bao Jiansheng,makes a comparative study,and draws the following conclusions :(1)Content setting : Both editions of textbooks have implemented the holistic view of textbook compilation.(2)Knowledge structure :The arrangement of knowledge structure of the two editions of textbooks is roughly the same,both have strong logic and systematic,and pay attention to the construction of probability theory system.The difference is that the New People' s Education A Edition Textbook knowledge structure is more compact,and can better reflect the application of mathematics,but the introduction of basic concepts is relatively simple;the new version of Beijing Normal University pays more attention to the foundation and formation process of knowledge,but there is still room for broadening the breadth of knowledge.(3)The difficulty of examples and exercises : the comprehensive difficulty of the probability chapters in the New People ' s Education A edition is higher than that in the New North Normal University edition.Based on the research results,suggestions on teacher teaching and textbook compilation are put forward.Teachers ' teaching :(1)Image classroom teaching language.(2)Teaching in the experiment to maintain classroom vitality.(3)Focusing on the structure of knowledge.(4)Selective exercise teaching.Textbook compilation :(1)Pay attention to the compilation of basic knowledge.(2)Strengthening the connection between probability knowledge and real life.(3)Strengthening the exemplary role of examples.
