本研究主要探討我國國小學生數感表現現況，並據以了解不同年級、性別學生間的差異情況。本研究以新竹縣市、苗栗縣九所學校的四、五、六年級學生共703人作為研究樣本。研究工具採用改編的數感測驗問卷，測驗內容包括數的意義、數的運算、運算策略、數與規則參照四個主軸。
依據資料分析結果，本研究主要發現如下：（一）我國學生數感測驗表現不如美國學生；（二）不同年級學生在數感測驗得分上有顯著差異存在，而且會隨著年級的增加而越來越高；（三）不同性別學生在數感測驗表現沒有差異。

This study focused on the number of elementary school students' performance, position sense, and according to the understanding of different grades of gender differences among students. In this study, Hsinchu City, Miaoli County, nine schools in grades four, five, six students as a study sample of 703 people. Research tools using a questionnaire adapted from number sense test, meaning the number of tests including, computing, computing strategy, the number of reference and rules of number four spindle.
The findings of this study, the main findings are as follows:
(1) the number of students a sense of student test performance than the United States;
(2) the number of students in different grades sense the presence of a significant difference test scores, grades and will increase as more higher and higher;
(3) gender differences in the number of students do not have a sense of test performance;
