A Comparative Study On The Recognition Of Decimals In Primary School Mathematics Textbooks Published By People's Education Edition, Jiangsu Education Edition, And Shanghai Edition

Textbook is an important carrier of the course,the quality of teaching materials indirectly affect the quality of teaching and student learning.At present,our country is in the wave of new curriculum reform.Textbook reform is also an inevitable topic.There are a large number of versions of primary school mathematics textbooks and more and more comparative studies on various textbooks.It is hoped that by studying various editions will be improved Teaching materials to make it more suitable for the students.PEP and SSE textbooks are compiled based on the curriculum standards promulgated by the Ministry of Education and are widely used.At the same time,the textbooks of Shanghai Primary School enable students to achieve excellent global success in three major areas of reading,math and science.They are used by some English classrooms and are based on the curriculum standards set by Shanghai Local Education Bureau.Therefore,this article will choose PEP,Sujiao version,Shanghai version of the three textbooks for analysis and research."Decimal" is an important number concept for primary school students to recognize.It also has important practical significance in life.In this paper,we use the methods of literature,text analysis And interviews,the qualitative and quantitative combination of the three versions of the text to understand the comparative study of decimal,from the textbook arrangement system,the selection of teaching materials,examples of questions set and exercise levels of these dimensions were analyzed.By comparing the three versions found in the textbook system generally adopted from simple to complex easy to difficult way,and in the subject have created a situation,the purpose is to enable students to better understand the knowledge of decimals.However,the Sujiao version and the PEP versioned the decimal fraction,and the reasoning level and comprehensive knowledge of the Sujiao version were higher than that of the other two versions.The logic of the PEP version was more difficult and more difficult.Interesting slightly better.And on the basis of comparison,some suggestions are put forward,including the interestingness of PEP to increase knowledge.Shanghai PEP needs to embody spiraling arrangement;In addition,all three versions Emphasis on improving the level of reasoning and knowledge of the comprehensive level.
