小学生估算能力现状的调查研究

20世纪80年代以来，国内外基础教育界开始高度关注估算问题，估算教学成为小学数学计算教学的一个重要内容。估算能力的培养对于加深儿童对计算或测量结果的概括性、整体性认识和理解，促进儿童对数量关系和空间形式的合理判断与推理方面有着重要作用。本文抽取了杭州市的两所小学，通过数据分析，得出三、四、五年级学生估算的准确度，估算能力的年龄差异、性别差异特征，以及分析小学生估算策略选择的发展现状，在此基础上提出未来需要解决的问题，以期望对今后的研究工作有所帮助。

Abstract

Since the nineteen eighties, the domestic and international basic education circles begin to attach great importance to the issue of computational estimation, computational estimation has become an important content of primary school mathematics teaching. Estimate ability plays an important role in enhance children's calculations or generality, integrity of understanding and the understanding of the test results, to promote children's reasonable judgment of quantity relationship and space form and reasoning. This paper extracted the two primary schools in Hangzhou, through data analysis, Draw the conclusion that three, four, five grade students 'estimation accuracy, the age difference of estimate, gender difference characteristics, as well as analyzing the development of the pupils estimation strategy choice, Accordingly, the author makes a necessary analysis and puts forward some suggestions on improving the status quo of computational estimation
