小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,计算要到达新课程目标,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,
The level of computing power of primary school students, 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, calculating the goal of reaching the new curriculum can not be accomplished by changing students’ computing habits. 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 an effective calculation of teaching, in addition to the difficulty of decomposition in teaching,
