| In recent years,China has achieved a transformation from "one syllabus with multiple textbooks" to "one standard with multiple textbooks".Shanghai has also issued the "Shanghai Mathematics Curriculum Standards for Primary and Secondary Schools" that are suitable for regional development.China has presented a situation of"multiple standards with multiple textbooks",and research on various versions of textbooks has also been carried out accordingly.Among the knowledge points involved in primary school mathematics,fraction is an important content.It is the expansion of natural numbers,the bridge connecting integers and decimals,and the basis for the expansion of rational number.Fraction is also considered to be the most complex,abstract,and problem prone concept.Pupils find it difficult to learn mathematics from fraction,which is crucial for future mathematics learning,So the importance of score content conflicts with the reality of students’ difficulty learning scores,making scores a hot topic in mathematical education research.Textbooks are very important curriculum resources for teachers’ teaching and the media for teacher-student interaction in teaching.By using comparative research and text analysis methods,we can analyze and compare the layout system,curriculum content,example arrangement and exercise arrangement of the primary school mathematics textbooks of the People’s Education Edition,the Soviet Education Edition and the Shanghai Education Edition,and analyze the characteristics,focus and respective advantages and disadvantages of various textbooks,It can enrich our theoretical research on the comparison of primary school mathematics textbooks and provide theoretical basis for front-line teachers’ teaching.Through the comparative study of the three versions of textbooks,we can draw the following conclusions:the content distribution of the Jiangsu Education Edition and the People’s Education Edition is relatively centralized,and the Shanghai Education Edition is relatively scattered;The style columns of the Shanghai Education Press are relatively simple;The textbook of the Jiangsu Education Edition is more practical,interesting and operational,while the Shanghai Education Edition is more scientific;The three versions of the textbook have a low degree of openness;There are obvious differences in the difficulty of the example exercises in the three versions of textbooks.Based on the reconstruction and use of the textbook,combined with the effectiveness of the use and interview results,the following suggestions for the teachers of each version of the textbook are proposed:Teachers can design open-ended questions in a timely manner based on textbook topics;Teachers can moderately increase interesting operational activities based on textbooks;Teachers should appropriately add diverse backgrounds when introducing in the classroom;Teachers should moderately increase comprehensive exercises during classroom practice. |
