在低年级的数学教学中,计算教学占了重要的地位,因此,夯实低年级学生的计算基础,是低年级数学教学的一项重要任务。但是在计算过程中,孩子经常会出现这样或那样的错误。在寻找错误原因的时候,我们不能把原因简单地归结为“粗心”二字。仔细分析孩子计算中的这些错误,其实我们可以归结为以下几个方面:一、认知偏差算法多样化能给孩子更多发挥的空间,但部分孩子在面对多种多样的算法时,只是走马观花地欣赏一遍,最后其他孩子认为 In the lower grades of mathematics teaching, computational teaching occupies an important position, therefore, to consolidate the computing basis of lower grades students, mathematics teaching in lower grades is an important task. But in the calculation process, children often appear this or that mistake. When looking for the cause of the error, we can not simply attribute the reason to the word “carelessness.” A careful analysis of these errors in children’s calculations, in fact, we can be attributed to the following aspects: First, the diversity of cognitive bias algorithm can give children more space to play, but some children in the face of a variety of algorithms, but Appreciate it again and again, and finally other children think
