A Comparative Study Of Three Versions Of Elementary School Mathematics Score Concept Teaching System

The teaching of fraction concept is a very important content in fraction teaching.The introduction of score in primary school is an important extension of students'cognition number,and the concept of score has always been a major difficulty for primary school students.The combination of teaching practice and theoretical research is an important way to improve the quality of textbook compilation.By communicating with teachers and combining with themselves,the author puts forward three questions for the teaching system of "score concept":?Score is a mathematical concept with multiple meanings,how to arrange the teaching materials so that students can get the best understanding effect;?Whether the knowledge of score unit should be introduced in the primary education stage;?The nature and score of ratio how to distinguish and introduce the nature of the two,and to what extent they can replace each other in the primary school teaching stage.This paper mainly adopts the method of literature research and comparative analysis.Under the guidance of the three questions raised,this paper makes a comparative analysis of three versions of textbooks,namely,the human education version,the Beijing Normal University version and the Jiangsu Education version,on the four teaching contents of"the concept of score","the meaning of score","the basic nature of score" and "the meaning and nature of comparison".Through the comparative study,combined with the primary school mathematics teaching theory,this paper expounds the thinking of the above problems and puts forward some suggestions for the compilation of teaching materials,aiming to provide some references for teachers to better understand,reorganize and use the teaching materials,so as to absorb the advantages and advantages of various teaching materials.At the same time,try to make the teaching system of the concept of score more perfect,and constantly improve the quality of the compilation of teaching materials,so that the teaching materials can better serve the teaching.
