计算是数学教学中应用最多、涉及面最广的一项数学技能,学生计算技能的好坏直接影响高一层次的数学学习。在日常教学中,经常听到有学生说:“这次考试题我全会做,就是计算错了,扣掉了十多分,真可惜!”每每听到这样的话,笔者就不禁会想:这到底是谁的问题,怎样才能有效提高学生计算的正确率呢?下面笔者谈三点提高学生计算正确率的有效策略。一、认真读题,整体把握,合理运算随着年级的升高,有些计算题目开始
Calculation is the most widely used mathematics teaching, covering a wide range of math skills, the quality of students’ calculation skills directly affect a higher level of maths learning. In daily teaching, I often hear some students say: “This exam questions I do, is calculated wrong, deducted more than 10 points, it is a pity!” Every time I hear this, I can not help but think : Who is this problem in the end, how can we effectively improve the accuracy of student computing? Here I talk about three effective strategies to improve students’ accuracy. First, serious reading questions, the overall grasp, a reasonable operation As the grade increases, some calculation problems began
