Investigation On The Sense Of Quantity Among Sixth Grade Primary School Students And Teaching Suggestions

"Compulsory Education Mathematics Curriculum Standards(2022 edition)" adds the core quality of "sense of quantity" to the primary school stage,which is an important period for the development of sense of quantity.However,there are few research results on the sense of quantity of primary school students.Therefore,it is of certain value and significance to study the current situation of sixth grade students’ sense of quantity.This paper aims to study the current level and problems of sixth grade students’ sense of quantity by using literature research,questionnaire survey and interview,and combining qualitative research with quantitative research.In this study,a questionnaire(self-report of measurement level and measurement test paper)was prepared according to the existing studies for pre-test,and then a formal questionnaire was formed.Then,more than 300 sixth grade students from three primary schools in three regions were investigated.Then,based on the analysis of the survey results and interviews with teachers,the basic situation and main problems of pupils’ sense of quantity are discussed.Finally,the corresponding teaching suggestions are put forward.The main findings of this study include: the results of self-report on the level of sense of quantity show that the majority of the test subjects are in the middle level,and the students think that the self-performance is in the order of quantity perception dimension,quantity estimation dimension and quantity reasoning dimension from good to bad.Quantity sense test paper is divided into quantitative analysis and qualitative analysis.The results of quantitative analysis show that the level of quantity sense of the sixth grade students is above the average level;There is a significant positive correlation between test scores and self-reports.There were differences in the performance of the three dimensions of the volume sense test,and there was no gender difference.The qualitative analysis results show that the deficiency of the quantitative perception dimension lies in the lack of life knowledge and life experience;The deficiency of the estimation dimension lies in the low estimation ability or improper use of strategy.The deficiency of the reasoning dimension of quantity lies in the lack of logical thinking or the lack of laws.On this basis,the teaching suggestions include: before class,teachers should pay attention to professional knowledge of sense of quantity and strengthen sense of quantity consciousness;Teachers should set teaching objectives reasonably and improve teaching quality with sense of quantity.In class,teachers should emphasize spatial measurement and promote the cultivation effect of sense of quantity.Teachers should increase hands-on operation and enhance the personal experience of sense of quantity.We can also cultivate the sense of quantity from different dimensions,and pay attention to the introduction of life situations in the perception of quantity.Strengthening the training of estimation ability in the estimation of quantity;Develop students’ logical thinking in quantitative reasoning.After class,we should pay attention to homework feedback,help students to check the gaps;Students should be guided to learn independently and accumulate quantitative knowledge.
