A Comparative Study Of The Content Of The Junior Middle School Mathematics Circle Between The People's Education Edition And The Beijing Normal University Edition

Since the National Ministry of Education promulgated Mathematics Curriculum Standards for Full-time Compulsory Education(Experimental Draft)in 2001,the reform of mathematics curriculum has been carried out in various regions,which has resulted in a situation of more than one syllabus.Various versions of mathematics textbooks with different characteristics have been launched all over the country.These textbooks provide extensive thinking space for textbook compilers and educators.Because the textbooks of People's Education Press and Peking Normal University have the most extensive use,this paper confirms that the two versions of textbooks are taken as the research object.As one of the basic graphics in plane geometry,circle plays an important role in the teaching of mathematical geometry in junior middle school.However,through consulting a large number of comparative research materials on textbooks,it is found that comparative research on the content of circle in junior middle school is very rare.The other studies are qualitative analysis,lack of objective basis,lack of data analysis and incomplete analysis of the research results.Therefore,in this paper,literature analysis,comparative analysis and statistical method are used to compare the three aspects of circle content setting,course difficulty and exercise difficulty.In qualitative comparison,the circle in the two versions of textbooks is analyzed.At the same time,this paper objectively and quantitatively compares the curriculum difficulty model proposed by Professor Shi Ningzhong and the comprehensive difficulty model of exercises proposed by Professor Bao Jiansheng,makes a more comprehensive analysis of the characteristics of the round content,explores the similarities and differences between the two versions of the textbooks,analyses the reasons for the differences,and summarizes their advantages and disadvantages.This paper makes a comparative analysis of the content setting,course difficulty and exercise difficulty of the round content in the textbooks of People's Education Press and Peking Normal University.It analyses the content setting from three aspects: system structure,illustration configuration and column setting.It also analyses the course difficulty from three aspects: course time,course breadth and course depth.It also analyses the course difficulty from three aspects: inquiry factor,background factor,operation factor,reasoning factor and knowledge content.These five factors analyze the difficulty of exercises,so as to discover the characteristics,advantages and disadvantages of the two versions of textbooks,and then provide suggestions for textbook compilers and front-line teachers on textbook compilation and relevant teaching references.
