A Study On The Change Of "Preliminary Understanding Of Scores" Arrangement In Primary School Textbooks Of "PEP"(1951-2014)

Score is not only an important content in the knowledge system of primary mathematics,but also an important extension of the concept of number.Preliminary understanding of score is the first step in the content of primary school learning score.People's Education Publishing House compiled a set of Arithmetic Textbooks for Advanced Primary Schools from 1951 to 1954.Among them,the first volume set up the relevant content of "the preliminary understanding of scores",which shows that it occupies an important position in the compilation of mathematics textbooks for primary schools.Based on the eight sets of primary school mathematics textbooks published by People's Education Publishing House from 1951 to 2014,this paper takes the arrangement and setting of the relevant content of the preliminary understanding of scores as the research object,and elaborates its changes in three stages.Specific research methods use literature research,comparative analysis and chart method.According to the syllabus(curriculum standard),this paper makes a comparative analysis of the teaching objectives and requirements of the preliminary understanding of the score content,the background,changes and characteristics of the arrangement of the structure.Specific research contents are as follows:Based on the syllabus(curriculum standard)and the background of the times,this paper elaborates the background of the arrangement of primary school mathematics textbooks,and makes a comparative analysis of the structural arrangement of the "preliminary understanding of scores",the way of concept expression,the setting of examples,exercises and exercises in primary school mathematics textbooks.This paper analyses the factors influencing the change of primary school mathematics scores in different periods.This paper discusses the changing characteristics of the relevant contents of the preliminary understanding of scores in textbooks in different periods.This paper expounds the changes in the arrangement of the relevant contents of the preliminary understanding of the scores in primary school mathematics textbooks,and on this basis,gives corresponding suggestions on the arrangement of textbooks.
