计算能力是小学数学教学中应该培养和必备的一种主要的能力,但相当一部分的学生在计算过程中会出现或多或少的意想不到的错误,我们总是简单地认为是学生平时马虎、粗心造成的。其实不然,有些错误的产生是有原因的。一、非智力因素的影响1.认识简单,感知失误当学生在计算时,总是首先利用“眼睛”这个感官感知数字和运算符号。因此,他们只注意到数据和符号的本身意义,对其相似的符号、意义缺乏认真思考,往往会引起计算失误。类似的情况有 Computational ability is a major ability that primary school mathematics teaching should be cultivated and essential, but a considerable number of students in the calculation process will appear more or less unexpected errors, we always think that students usually sloppy Carelessly caused. In actual fact, some mistakes are made for a reason. First, the impact of non-intellectual factors 1. Awareness of simple, perceived errors When students are calculating, always use the “eyes” of the senses and arithmetic symbols. Therefore, they only pay attention to the intrinsic meaning of data and symbols, and lacking serious consideration of their similar symbols and meanings often cause calculation errors. A similar situation there
