培养学生准确、迅速、灵活的计算能力是小学数学教育的一项重要任务。但是,在教学实践中经常可以发现小学生计算出错的情况,我想究其原因是多方面的,为了减少计算错误就要认真分析产生错误的原因,以便对症下药,小学生计算错误的产生除了对有关计算的数学概念的理解掌握等方面的问题外,另一方面则是心理障碍方面,通过对产生计算错误成 Developing students’ accurate, rapid and flexible computing skills is an important task in primary school mathematics education. However, in my teaching practice, it is often found that primary school students make mistakes. The reason I think of it is that there are many reasons for it. In order to reduce the mistakes in calculation, we must carefully analyze the causes of mistakes in order to remedy the mistakes. In addition to calculating the mistakes of pupils, Mathematical understanding of the concept of mastery and other aspects of the problem, on the other hand is the psychological aspects, through the calculation error into
