Study On The Types And Causes Of Division Errors In Grade 4 Students With Learning Difficulties

Calculation plays an important role in mathematics teaching in primary school.Division calculation is the core of number and algebra.In addition,division calculation is the most difficult part of the four operations,so students are most likely to make a variety of mistakes in the process of division calculation.In this context,this paper studies the following issues:(1)Compared with ordinary students,what are the characteristics of the learning difficulties students' mistakes in division calculation?(2)What is the reason that division computation error appears in unskilled students?(3)What strategies can be used to improve the level of division?In order to study the following problems,this paper adopted the following methods: first,test method and analysis method were adopted to distribute the self-compiled test paper to the students with learning difficulties and non-learning difficulties,and the calculation situation of the students with learning difficulties and non-learning difficulties was compared,so as to analyze the characteristics of the students with learning difficulties making mistakes in division calculation.Questions two and three use the method of questionnaire and interview,all students have done a questionnaire;Three substitute teachers were interviewed to analyze the reasons for the students' mistakes.Research findings:(1)First of all,learning difficulties students appear relatively low-level mistakes,such as copying wrong questions,wrong number;Secondly,the basic operational ability of students with learning difficulties is relatively poor.Students with learning difficulties often make a variety of mistakes because they are not familiar with addition and subtraction within 20 and multiplication table within 99.Finally,in the calculation,the students with learning difficulties are confused in thinking and often confuse addition and subtraction,minuend and subtraction,resulting in some errors different from those of the students without learning difficulties.(2)There are four reasons for unskilled students to make mistakes in division calculation: weak basic operational ability,inability to understand the algorithm,inattention and confusion.(3)There are two ways to improve the level of division.From the student aspect,strengthens the basic knowledge the study,strengthens the computation theory study and forms the good computation custom.From the teacher aspect,must implement the stratified teaching,the optimized teaching method.
