Case-intervention Study On The Transformation Of Mathematics And Difficulties In The Teaching Of Equations In Primary Schools

Usually,almost every class has one or more students in grades below,there are some difficulties in the study,the students usually referred to as“learning difficulties students”.Learning difficulties students in nearly 30 years of mathematics education research an important topic.Learning difficulties students to study in this paper refers to the physical defects,difficulties in learning mathematics,students“LDS”for short.What is the cause of the students mathematics learning difficulties,and access to external intervention,are all worth exploring.According to the opinion of the two fifth grade math teacher,choose from the five grade four class performance of 25 temporarily backward students,let the 25 students answer paper equation and reasoning test papers.Analyze the answer of the test paper,find out the five students who have the wrong way to solve the problem,organize and summarize the mistakes,and classify the different types of errors.Then from the 5 students selected 3 typical students as a case study,the research methods of interview and questionnaire investigation,sued up the causes of learning difficulties 3number of poor students.Representation system based on the Bruner and mastery learning theory,design three solving methods to teach 3 concrete number trapped,observe their performance and characteristics of every intervention,and record whether they can successfully.Eventually concluded that intelligence difference can get transformation,for individual types of equation transformation effect is general,not intellectual inquiry into this can completely transformed.This paper mainly studies from the following aspects.In the first part,the author puts forward the question and expounds the research background,research purpose and significance of this thesis.Referring to the domestic and foreign research literature on the study of several trapped students,makes an in-depth analysis of the existing research achievements and research status,and determines the definition and research direction of several trapped students.In the second part,according to the actual interview,observation and communication between the teachers,the causes of logarithmic depression are analyzed.In the third part,based on the corresponding theoretical basis,three methods of solving the equation are designed,and the research object and research idea are determined.The fourth part,select the number of three typical stuck through the case study of raw log stuck to intervene,detailed records every time log stuck gave birth to theintervention of the process,trying to scientifically,specifically in their performance in the process of each intervention and characteristics,and the corresponding conclusions.The fifth part summarizes the research contents of this paper,and puts forward Suggestions and reflections on the shortcomings of this study.
