Study On The Teaching Strategy Of Primary School Fraction

This paper is mainly on the current primary education stage of the fraction instructional strategies to carry out research.In this study,based on the content of the fraction in the primary school math teaching materials of the human teaching version and the years of practical experience in mathematics teaching in primary schools,the "Primary School Fraction Knowledge Survey Paper" was prepared,and 425 sixth-grade students in seven classes of four local primary schools were studied.The three aspects of fraction problem solving were investigated for students' knowledge of fraction.The results of the test are analyzed and thought out,and the teaching strategies of fraction,fraction calculation and fraction problem solving are put forward.Through practical teaching and case analysis,the fraction instructional strategies is tested and constantly improved.The content of the paper mainly has the following aspects:First of all,in the introduction,the research questions are presented,it mainly expounds the research problem,the definition of the basic concept,the purpose and significance of the research,the research method situ,the current situation of domestic and foreign research and the historical development of the fraction.Secondly,it analyzes the students' master of the content of the fraction.Adopt the analysis of students' answers,we find out the problems in the student's fraction study,and then start from the question and continue the next research,so as to lay the foundation for exploring the instructional strategies of fraction.Mainly from the significance of the fraction,the fraction operation,the fraction to solve the problem three aspects to sum up the instructional strategies suitable for primary school students.The teaching strategies of the meaning of fraction are: to strengthen the understanding of the business definition,to use the situational teaching method to help students understand the definition of fraction,and to emphasize the fraction unit "1" with flexible understanding unit.The strategies of fraction calculation teaching are: using learning tools to promote students' understanding of the algorithm,combining the algorithm effectively,using knowledge migration effectively,combining the number of forms,abstracting into visual image,and using the method of transformation and migration to help studentsunderstand the division of fraction.The teaching strategies of fraction problem solving are: to train students' reading skills to accurately grasp the meaning of the problem,to use numerical combination ideas to help students to clarify the quantitative relationship,to pay attention to the penetration of mathematical thought methods when teaching special fraction to solve problems,and to make use of a variety of questions to make students understand the connection and difference between the problems.Finally,some suggestions are put of fraction teaching.According to the current situation of fractional education.This study puts forward the following suggestions for the teaching of fraction: dig deep into teaching materials and improve their teaching literacy.
