小学数学计算具有基础性和工具性的特征。然而,随着电脑运用的普及,很多教师认为小学计算能力的培养不那么重要了。经过长期的调查研究,我们发现小学数学教学存在以下几个误区:误区之一,计算教学依赖于情境。误区之二,练习时间无保证。误区三,方法多样化变成“形式化”。误区四,忽视口算的正确率以及口算 Elementary mathematics calculation has the basic and instrumental characteristics. However, with the popularization of computer use, many teachers think that the training of primary computing power is not so important. After a long period of investigation and study, we found that there are several misunderstandings in elementary mathematics teaching: One of the errors, computing teaching depends on the situation. Misunderstanding two practice time without guarantee. Misunderstandings Third, the method of diversification into “formal ”. Misunderstanding four, ignore the accuracy of the mouth count as well as the mouth count
