新课标下的计算教学在教材编排上注重创设具体的问题情境与解决实际问题相结合,创设生动有趣的情境,从生活问题中引出数学问题,积极探索计算教学的新模式。现在,比较受大家认同的计算教学模式大致是这样的:情境导入—算法呈现—比较提炼—明确算理—算法巩固。新的模式注重课堂探究,但是训练密度不够,重算理,轻算法,学生计算技能较差,不利于学生的数学学习。
The teaching of calculation under the new curriculum standard pays attention to the creation of specific problem situations and the solution of practical problems in the teaching material arrangement, creates vivid and interesting situations, leads the mathematical problems from the life problems, and actively explores the new mode of calculation and teaching. Now, more generally accepted by everyone in the calculation of teaching mode is roughly the case: situational import - algorithm rendering - more refined - clear arithmetic - algorithm consolidation. The new model focuses on classroom exploration, but the training density is not enough, recalculation, light algorithm, poor calculation skills of students, is not conducive to students’ math learning.
