当前,很多教师深刻感受到学生在数学学习的过程中呈现“一听就懂,一做就错,眼高手低”的现象,其计算能力明显下降;究其原因,学生口算的准确率及速度,影响着学生笔算的准确率及运算速度。所以,要使学生的计算能力提高,必须要抓好口算教学。
At present, many teachers deeply feel that the students’ performance of mathematics learning presents a phenomenon of “one to understand, one to make mistakes, high eyes to hand low”, and its computing ability declines obviously. The reason, the accuracy and speed of students , Affecting the accuracy of students’ pen calculations and computing speed. Therefore, in order to improve the computational ability of students, we must do a good job teaching mathematics.
