A Comparative Study Of "the Understanding Of The Circle" In Mathematics Textbooks For Elementary Schools In Jiangsu, Shanghai And Hong Kong

With the deepening of curriculum reform,more and more attention has been paid to the study of textbooks,and the comparative study of different versions of primary mathematics textbooks has become a hot issue.Comparing textbooks can improve the compilation of each edition of textbooks,improve the quality of textbooks,and make them more suitable for the development of students.Hong Kong,Shanghai and Jiangsu are relatively economically developed areas in China.Primary and secondary school students have achieved good results in student assessment project tests both at home and abroad,which should be related to the textbooks they use.Therefore,this study chooses three editions of textbooks:Soviet Educational Press,Shanghai Educational Press and Hong Kong Educational Press for comparative analysis,in order to find out the characteristics and explore the rulesThe curriculum content of circle occupies an important position in elementary mathematics,and it is a turning point from understanding geometry to bending.In this paper,by using the methods of literature,text analysis,comparative analysis and interview,the author combines the qualitative and quantitative methods to make a comparative study of the understanding of the circle in the three editions of the textbooks mentioned above.Comparing the content system,example design,exercise arrangement and comprehensive difficulty of the textbook,the paper analyses the content distribution,column design,breadth and depth,the situation design and expression way,topic type,opening degree,the number,type and difficulty of exercises.Through comparative analysis,the following conclusions are drawn:The content distribution of the three editions of textbooks is relatively centralized,and the Hong Kong edition has a large span.Soviet Educational Press and Hong Kong Educational Press have diversified sections,while Shanghai Educational Press is relatively single.Hong Kong Edition has the broadest content,while Shanghai Edition has the deepest content.The examples of the three editions of the textbooks all pay attention to the life and operation situation,with abundant pictures and texts.The Hong Kong edition of textbooks is rich in subject types,open and problem-oriented.The exercises of Soviet Educational Press and Hong Kong Educational Press have a sense of hierarchy,and the exercises of Soviet Educational Press are the most difficult.According to the conclusion of the comparison,the following suggestions are put forward:Hong Kong Edition Textbooks Can Appropriately Reduce Grade Span.The Shanghai Educational Press can set up diversified columns to enrich the teaching function of textbooks.Soviet Educational Press and Shanghai Educational Press can provide more operational activities.The three editions of the textbooks can arrange multi-level exercises and maintain appropriate difficulty.
