| 摘 要： | 以180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,小学生被试数字广度的发展和口算速度的提高是促进加法口算广度发展的两个重要因素。

| Abstract: | 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. The experiment discovered that the development of the figure spans and mental addition speeds of the schoolchild were two important factors promoting the development of mental addition spans. |
