| 摘 要： | 为考察大学生的口算能力,我们随机选取30名大学生为被试进行口算的实验研究,主要结论如下:(1)大学生的口算速率在加、减、乘、除法之间存在差异,从快到慢依次为:除法,借位减法,不借位减法,不进位加法,进位加法,乘法;(2)口算的广度从大到小依次为:不进位的加法广度,进位加法广度,不借位减法广度,借位减法广度,除法广度,乘法广度;(3)大学生口算的速度和广度既无显著的专业差异,也无显著的性别差异.

| Abstract: | In order to investigate the ability of college student mental arithmetic ,we choose randomly thirty college students for the experiment about the ability of college student's mental arithmetic. The main conclusions are (1)There are differences among addition,subtraction, multiplication, division in collage student's mental arithmetic speed the ordor. From fast to slow is division,subtract,not borrowing ten subtract,addition carrying a number ,addition not carrying a number, multiplication. (2)The ordor from long to short in the span of mental arithmetic is: addition not carrying a number, additon carrying a number, subtract not borrowing ten, subtract borrowing ten, division, multiplication.(3)There are no significant mental arithmetic speed and span differences relavent to sex and specialty. |
