A Comparative Study Of "Time Recognition" In Mathematics Textbooks For Elementary Schools In Jiangsu, Shanghai And Hong Kong

The textbook is the most basic curriculum resource,the main basis for teaching and learning,and the source of primary school students' ability to acquire knowledge and develop.This study selects three versions of primary school mathematics textbooks in Jiangsu,Shanghai and Hong Kong as research objects.Among them,the Jiangsu Education Edition is based in Jiangsu and is widely used throughout the country;the Shanghai Education Edition is compiled according to the Shanghai curriculun standards,and has certain characteristics for the preparation of the Shanghai area;Hong Kong has more experience in the preparation of textbooks,and integrates Eastern and Western cultures.The characteristics of the territory can provide reference for the mainland.“Time recognition" belongs to the "common quantity" part and is arranged in the field of " number and algebra "."Time" is one of the important concepts of primary school mathematics and plays an important role in the development of children's cognition.Comparing the time-recognition content in different versions of textbooks,highlighting the advantages and disadvantages of each version of the time to understand the content writing,can provide reference and reference for the revision of the content and classroom teaching in the textbook.This study uses literature method,text analysis method,comparative research method,combined with quantitative description and qualitative description,from content setting,content distribution,style column,content breadth,content depth,content difficulty,problem difficulty,overall difficulty,etc.Aspects were compared and analyzed.The study found that the content of the content recognition in the Soviet Union and Shanghai is relatively concentrated,and the textbooks in Hong Kong are more scattered.The textbooks in the third edition have their own strengths.The textbooks in Hong Kong are more distinctive.The content of the textbooks in Hong Kong is the most extensive,the depth of the curriculum,and the overall difficulty.Reference;Su,Hong Kong version of the textbook examples closed the number of questions,lack of inquiry awareness;three versions of the problem background needs to be optimized,the scientific background is generally less.Based on the comparative analysis of the time-recognition content of the three versions of primary school mathematics textbooks,the following suggestions are proposed:the content of the textbooks of the Jiangsu Education and Shanghai Education Editions should reflect the spiraling concept;the Hong Kong version of the textbooks is more distinctive and can be used for Su,The two editions of the Shanghai textbook draw on;the three editions appropriately increase the time to understand the content examples and broaden the students' problem-solving thinking;the three editions should focus on the diversification of the problem background and focus on improving the scientific background of the exercises.
