小学数学中计算具有基础性和工具性。在小学阶段学好四则混合运算计算,并形成一定的计算能力,这是终身有益的。但是,笔者在调研中发现了计算教学值得深思的现象,以往对学生计算能力的要求,如计算方法、技巧与速度等,现在很少提了,学生的计算能力比以前下降了,主要表现在计算正
Calculations in elementary mathematics are basic and instrumental. Learn four mixed computing in elementary school, and form a certain amount of computing power, which is lifelong beneficial. However, the author found in the investigation of the phenomenon of computational thinking is worth pondering. In the past, students ’calculating abilities, such as calculating methods, skills and speed, are seldom mentioned nowadays. Students’ computing abilities have dropped more than before, Calculate positive
