| 摘 要： | 借鉴Lemaire与Siegler提出的儿童认知策略的一般概念框架,运用自编的估算题目对210名小学六年级儿童的估算能力进行了初步分析。结果表明;小学六年级儿童具有一定的估算能力,只是所给估算答案明显受到数字类型和运算规则的交互影响;他们会运用多种估算策略,但各种策略的使用频率、执行速度和准确性都存在明显差异。文章还对儿童估算策略的评估做了深入讨论。

| Abstract: | Using a general concept framework about children's cognitive strategy developed by Lemaire & Siegler (1995) and self-made materials, this paper investigated 210 sixth grader's computational estimation competence of primary school. The results showed that: (1) the sixth graders had a definite ability to solve computational estimation problem, but there was a significant interaction between number type and operation rule, (2) although they could use several computational estimation strategies, but the differences in frequency, executive speed and accuracy among different strategies were all very great. The evaluation on children's computational estimation strategies was also deeply discussed. |
