计算是数学教学中的重要部分,是学生应具备的一种基本的数学技能,是帮助我们解决问题的工具。学生在数学学习过程中,特别是小学生在数的运算过程中,经常有出错现象,且错误比例越来越大,这种现象,老师苦恼,家长困惑,学生本人懊丧。分析计算出错的原因主要有以下几个方面。一、概念不清,算理不明许多学生在学习的过程中对概念掌握的不牢固,一知半解,甚至把相关的概念混淆,对算理、算法不能很好地掌握它 Computation is an important part of mathematics teaching. It is a basic mathematical skill that students should have and is a tool to help us to solve the problem. Students in mathematics learning process, especially primary school students in the computing process, often have errors, and the proportion of errors is increasing, this phenomenon, the teacher distressed, parents confused, the students themselves depressed. Analysis of the main reasons for the error are the following aspects. First, the concept is unclear, the arithmetic is unknown Many students in the learning process to grasp the concept of weak, poorly understood, or even confuse the concept of the arithmetic, the algorithm can not grasp it well
