新课程实施以来,很多老师都有这样的感觉:现在学生计算能力下降了,计算正确率不如以前,这方面的训练也明显减弱了,这样就直接导致学生数学素养的滑坡。这种现象越到高年级越明显,一些学生在解决问题时思路正确,但计算出了差错,导致功亏一篑。因此,我们在强化数学思考和解决问题能力培养的同时,不可忽视学生计算能力的培养。关注学生计算典型错误,有的放矢地进行预防、校正、训练,这是提升学生计算能力的有效途径。 Since the implementation of the new curriculum, many teachers have the feeling that nowadays students ’computing abilities have dropped and the calculation accuracy is not as good as before. The training in this area has also been obviously weakened, which directly leads to the decline in students’ mathematical literacy. The more obvious the phenomenon is, the higher the grade is. Some students have the right ideas in solving the problems, but they have calculated the errors and caused a loss. Therefore, we should not neglect the cultivation of students’ computing ability while strengthening the ability of thinking and solving problems in mathematics. Concerned about the typical calculation of student errors, targeted prevention, correction, training, which is an effective way to enhance students’ computing power.
