小学生加法口算时间的差异性研究

A Study of the Difference in Time of Pupils' Mental Arithmetic on Addition

将口算时间分解为运算时间和结果整合时间。二、四、六年级共90名小学生接受了加法口算的实验。结果表明,在一位数加多位数不进位加法口算中,口算时间的年级差异源于运算时间差异和整合时间差异;在一位数加多位数进位加法口算中,口算时间差异主要源于运算时间差异。

The author of this paper divided pupils＇ mental arithmetic time into operation time and integrating time. 90 pupils in the second, the fourth, and the sixth grades were tested. The results showed： There were significant grade differences in operation time and integrating time on non-carry addition mental arithmetic. There were significant grade differences in operation time on carry addition mental arithmetic, but there were not significant grade differences in integrating time.
