六年级学生数感与量感及其关系研究--以分数的数感与面积、体积的量感为例

Research on Number Sense,Quantity of Sense and Their Relationship among Sixth Grade Students--Taking the sense of number of fractions and the sense of quantity of area and volume as an example

通过对昆明地区六年级学生的数感与量感进行研究,发现六年级学生的数感发展水平与量感发展水平显著相关,数感整体与量感各维度之间显著相关,量感整体与数感各维度之间显著相关,六年级学生的数感与量感在成绩方面存在差异,在性别方面没有显著差异。建议教师在教学过程中要树立数感与量感相互联系的教学理念,借助数感建立学生对大度量单位的量感,促进学生数感与量感共同发展。

Through the research on the number sense and quantity of sense of the sixth grade students in Kunming,it is found that the development level of the number sense of the sixth grade students is significantly related to the development level of the quantity of sense,the overall number sense is significantly correlated with each dimension of the quantity of sense,and the over-all quantity of sense is significantly related to the number sense.There is a significant correlation between the dimensions.There are differences in grades between the number sense and the sense of quantity of the sixth grade students,but there is no signifi-cant difference in gender.It is suggested that teachers should establish the teaching concept that number sense and quantity of sense are interrelated in the teaching process,use number sense to establish students'sense of quantity for large measurement u-nits,and promote the common development of students'number sense and quantity sense.
