本研究考察了儿童在算术成绩上的差异是否与他们对位值理解的差异有关。对一组算术能力较差的中国儿童进行了位值概念培训。将他们在训练前和训练后的表现与两个对照组的儿童进行比较。结果表明，位值理解与加法和减法技能之间存在可靠的联系。此外，地点价值概念的培训被发现有效地提高了儿童对地点价值的理解和加法技能。讨论了算术指令的含义。(C)1997年学术出版社。
The present study examined whether children's variation in arithmetic performance was related to differences in their understanding of place-value. Training in place-value concepts was provided to a group of Chinese children who were poor in arithmetic. Their performance before and after the training was compared to that of the children in two control groups. The results showed that there were reliable connections between place-value understanding and addition and subtraction skills. Furthermore, training in place-value concepts was found to be effective in enhancing the children's place-value understanding and addition skills. Implications for instructions in arithmetic were discussed. (C) 1997 Academic Press.
