A Study On The Error Of Division Of Pupils' Scores

The calculation of the score is one of the important contents of the sixth grade mathematics of the Jiangsu Education Edition.The study of the score knowledge is also the place where many students are guilty.The study of scores is an extension of the concept of numbers.It is based on the arithmetic of integers and lays a foundation for the study of decimals,percentages and ratios.Learning scores is very important for students.This paper mainly studies the errors in the fractional division method.The sixth grade score division unit of the Jiangsu education edition is taken as the research content.The students' daily errors are taken as the research object,the score division error types are analyzed,and the errors are classified to propose targeted teaching strategy.This study is based on the score division of the sixth grade of the primary school mathematics of the Jiangsu Education Edition.Based on the sixth grade students of Yangzhou H Primary School,based on the rational analysis of the curriculum standards,the score knowledge in the textbooks,and the knowledge structure of the fractional division unit,Prepare the test volume,select the survey object to conduct the test,analyze the data,analyze the daily text of the student through text analysis,collect the error examples,and refer to the existing authoritative conclusions,so as to summarize the sixth-grade student score division error type.Error types are classified into cognitive errors and knowledge errors.Cognitive errors include fractional multiplication interference errors,approximation problems,unit "1" errors,failure to accurately distinguish between points and quantities,failure to comprehensively analyze problems caused by errors,errors in old knowledge,and errors caused by inaccurate perceptions.Knowledge-based errors are further divided into computational law errors and regulatory errors.Targeted education strategies are proposed for the types of errors:helping students understand the mathematics,mastering the rules of calculation,teaching students short divisions,reducing the number of points,making full use of the line graphs,helping students to identify quantitative relationships,helping students to correctly distinguish between points and The amount,help students understand the unit "1",find the standard amount,strengthen the practice,improve the students' computing ability,pay attention to the habit education,and teach the wrong examples.
