A Comparative Study Of "Awareness Of Integers" In Primary School Mathematics Textbooks Of People's Education Edition, Modern Edition And MPAH Edition

With the continuous deepening of curriculum reform,the review and thinking of textbooks will help us reflect on the shortcomings in curriculum reform.In recent years,math education in Hong Kong and Singapore has achieved fruitful results.They have witnessed their brilliant achievements on the international stage and are similar to the mainland in terms of cultural background and educational form.Therefore,this study selected People's Education Edition of the mainland primary school mathematics textbooks,Modern Edition textbooks of the Hong Kong,and MPAH version textbooks of the Singapore as research objects,and selected concepts and meanings that help students form numbers,develop students' sense of numbers,and use numbers."Integer recognition",which represents the things in everyday life,solves practical problems as a research object.By comparing and analyzing the three versions of "integer recognition",it can be valuable to China in the preparation of primary school mathematics "integer recognition" textbooks.Suggestions and experience.This research adopts comparative research,text analysis,on the People's Education Edition,MPAH and Modern Editions of "the understanding of the integer",illustrations,sample presentation and the content of the four aspects to compare difficulty,and study the main conclusions are as follows: the Modern Edition on setting up more diverse,People ' s Education Edition on the content more comprehensive,clear structure more reasonable,more balanced distribution of the intermediate MPAH in content distribution;People's Education Edition and paid more attention to use modern life and situational illustrations,MPAH Edition more inclined to use model class illustrations,the Modern Edition of the figure,each chapter has a chapter before the person has a chapter before the figure includes chapters,chapter MPAH Edition is not set before the figure and sample figure using proportion is higher,people figure includes and exercises using proportion is higher,three versions mainly interpreted illustrations as the main functional illustrations,but MPAH Edition of interpreted illustrations utilization rate is higher;Each of the three has its own characteristics,at different levels of knowledge,the presentation of each version is different.People's Education Edition has a higher level of content breadth,the MPAH Edition has a higher level of content depth,and the Modern Edition has a higher level of exercise difficulty.Through the proportion analysis of the three difficulty dimensions,it is concludedthat the comprehensive difficulty of the Modern Edition is higher than that of People's Education Edition,while the comprehensive difficulty of People's Education Edition is higher than that of the MPAH Edition.Based on People ' s Education Edition,Modern and MPAH Edition "integer" presentation about content,illustration,example and comparative study of four aspects: conclusion,difficult on the Chinese mainland are textbooks "integer" writing put forward the following Suggestions: rich columns,in the textbook "integer" grade content to have a balanced distribution is reasonable;Rational distribution of illustration types and functional illustrations;Examples should be presented in diversified forms to improve the guidance and inspiration of textbooks and pay attention to the space of students' induction,generalization and abstraction.The content depth and the level value of the difficulty of the exercise should be coordinated and unified,and the comprehensive difficulty of the "understanding of integers" part should be improved appropriately.
