A Comparative Study Of The Circle Content In The Third Edition Of Junior Middle School Mathematics Textbooks

Round as students come into contact with the first curve geometry,its importance is self-evident,students can better grasp the round part of the knowledge largely depends on the design of the teaching material,teaching material is to understand knowledge constitutes an important guide for students,the necessary reference for teacher is to impart knowledge,will study circle this chapter of the textbook for students' learning and teachers' teaching is provided a big help.At present our country middle school mathematics teaching material has nine versions,each version of the textbook has its advantages,but there are also short comings,so it is imperative to analyze the textbook.This paper takes the chapter of circle in the textbooks of the people's education edition,the edition of Beijing normal university and the edition of east China normal university in Shanxi Province as the research object,teaching material from the overall layout,specific design of the two perspectives,the arrangement of the sequence of textbook,content settings and exercises,literature review,comparative analysis,content analysis and statistics were used to study the textbookResearch of this paper is divided into three parts,the first part is the research purpose,research significance,and research methods,compared the teaching material analysis and the research status of circular.The second part is the specific analysis and comparison of the three versions of the textbook circle this chapter arrangement order,column settings,comparison of the number of exercises,as well as the proportion of each level of questions and other aspects and draw a conclusion.The third part is to draw the conclusion after comparative study,and reflect on it and put forward Suggestions.It is hoped that the study of these three parts will be helpful to the teaching of mathematics circle in junior middle school.Through the research on the chapter of the third edition textbook circle,the following conclusions are drawn:(1)Three versions of similar system arrangement,the beginning of each chapter has a chapter before the figure and the introduction,there are many programs designed to attract students in class activities,and through the exercises to consolidate what they have learned content,arranged at the end of chapter summary and review questions,let students form the framework of the knowledge system of this unit in their mind(2)The column design of classroom activities is very rich.For example,both the people's education edition and the edition of east China normal university have questions,thoughts and explorations,while both the edition of Beijing normal university and the edition of east China normal university have "do" and "read";as for the number of columns,there are 63 in the people's education edition(13 in total),80 in the Beijing normal university edition(11 in total),and 70 in the east China normal university edition(14 in total).It can be seen that the east China normal university edition has the(3)largest kind of columns and the Beijing normal university edition has the largest number of columns;for the specific content of the column,the relevant knowledge of mathematical history can be increased,and students can know the source of knowledge;(4)As for the problem sets,the three versions of the textbooks are mostly non-background exercises,which focus on the understanding of knowledge itself.The number of background exercises should be increased,among which the emphasis an background topics of “scientific situation” should be strengthened.
