A Comparative Study On The “Operation Content Of Numbers” In Primary Mathematics Textbooks

Each version of the textbook has its own characteristics,if we can compare different versions of the textbook,take the strengths,make up for the shortcomings,will certainly be able to promote the quality of the textbook.The calculation of numbers is one of the core contents of primary school mathematics textbooks,and it is also the basis of mathematics learning.Therefore,this study selected the calculation of numbers in the first learning section of primary school mathematics textbooks of PEP and Qingdao edition for comparative analysis.s.Based on the existing research,the dimensions of the comparison between the two textbooks are determined: a horizontal comparison of the compilation philosophy of the two textbooks;This paper makes a longitudinal comparison of the content composition,presentation mode and mathematical culture of "number operation" in the two editions of the textbooks,and then concludes the similarities,differences and characteristics of the two editions of the textbooks.Through the research,it is found that the compilation of the two textbooks both reflects the basic idea of the curriculum standard and has some similarities: in terms of content arrangement,the two textbooks adopt the way of content arrangement step by step and spiral upward.The selection of situations and materials is as close to students' real life as possible,and learning new knowledge is taken as a tool to solve problems in situations,so that students can integrate problem solving and knowledge learning in the same process,forming a system framework with problem solving as the clue.But there are also differences: the PEP textbook lays emphasis on the students' learning of basic mathematics knowledge in the concept of compilation.The arrangement system pays more attention to the strict logic and scientific nature.Compared with the Qingdao edition,the types of the sample questions and the presentation of mathematical culture are more abundant.The Qingdao edition of textbooks advocates more diversified teaching and learning methods to promote the development of The personality of the student.Attach importance to combining problem solving with learning basic knowledge and skills,so that students can appreciate the value of learning mathematics.The presentation of the textbook scene map is more holistic.Based on the teaching practice and interview,some suggestions are provided for the compilation,selection and use of the two editions of textbooks.The Qingdao version of textbooks should pay attention to optimizing the details of the arrangement of knowledge points,strengthen the connection between knowledge,and seek a balance between the breadth and depth of knowledge.Optimize the selection and display of sample problems;reasonably set the knowledge difficulty in examples and exercises;optimize the representation and application of the content of the history of mathematics.PEP textbooks should strengthen the integrity of situation design;appropriately expand the knowledge points,rationally arrange teaching content based on the actual situation of students' learning;rationally construct a platform for editors and teachers to communicate.
