摘要
通过对四到七年级的儿童解决32个简单的除法问题的调查,发现儿童在简单问题的除法计算上的表现存在着年龄的差异以及问题大小的影响作用。加法策略和乘法策略两种策略随年龄不同而变化。本文还讨论了提取策略不被常用和不随年龄变化的原因。总之,结果表明除法运算是一个独有的操作,对除法运算的后续研究可能会对更进一步理解算术的程序和概念上的知识是如何发展具有重要意义。
Age-related changes in children＇ s performance on simple division problems were investigated by asking children in Grade 4 to 7 to solve 32 simple division problems, and problem size effects were also found. ＂addition＂and ＂multiplication＂ strategies changed across age. Reasons for why retrieval use remains infrequent and age invariant are discussed. Overall, the results suggest that division is an unique operation and the continued study of division may have implications for further understanding of how procedural and conceptual knowledge of arithmetic develops.
