摘要
以 18 0名 1至 6年级小学生为被试考察了加法口算速度和广度的发展。结果表明小学生被试加法口算的速度和广度均随年级的增长而提高。 1至 4年级加法口算速度的增长率较高 ,4至 6年级增长率较低 ,发展减缓。加法口算广度的发展在 1至 4年级之间增长幅度较大 ;在 4至 6年级之间增长率降低 ,年级差异不显著。实验结果的分析还表明 。
The experiment investigated the development of the speeds and spans of mental addition of 180 primary school students. Results showed that the speeds and spans of mental addition of the pupils increased with the growth of subject's grades .The growth rate of the mental addition speeds and spans of the between first, second, third, and fourth grades were all higher than that the between fourth, fifth, and sixth grades.
