计算是小学低年级数学教学的重心。但是随着学生作业的减负,伴随而来的就是学生计算能力的下降。造成学生计算能力下降的原因主要有:非智力因素的作用,概念理解模糊,注意力的分配和转移能力差等,针对这些原因,教师急需从平时的课堂练习中找到解决的方法,从而提高学生的计算能力。 Calculation is the focus of the lower primary mathematics teaching. However, with the burdens of students ’homework, there is a decrease in the students’ computing abilities. For these reasons, teachers need to find ways to solve the usual classroom exercises to improve students’ ability to reduce computing power: non-intellectual factors, fuzzy understanding of concepts, poor attention distribution and transfer ability, etc. The computing power.
