学生的计算能力的高低,主要体现在计算的速率、正确率、技巧性、合理性等方面。针对学生速率和正确率偏低的情况,很多老师往往认为是学生计算不够仔细的原因。其实,计算要达到新课程目标,不是靠改变学生的计算习惯就可以完成的。计算技能需要通过一定的习题训练量才能形成,重要的是教师对计算教学的认识是否正确。如何进行有效的计算教学,除了在教学中分解难点,突出重点之外,我体会有如下:
The level of students’ computing power is mainly reflected in the calculation of the rate, accuracy, skill, rationality and so on. For the low rate of students and the accuracy of the situation, many teachers often think that students are not careful enough calculation reasons. In fact, the calculation to achieve the goal of the new curriculum, not by changing the computing habits of students can be completed. Computational skills need to be trained by a certain amount of exercises to form, it is important that teachers understand the teaching of computing is correct. How to carry out effective calculation teaching, apart from breaking down the teaching difficulties and highlighting the key points, I understand the following:
