新课程实施以来,计算教学有了很大变化。计算教学价值的重新定位、计算练习的减少,使得不少教师在一定程度上忽略了学生良好计算习惯的养成以及实际计算能力的提高。学生计算能力的弱化就像“蝴蝶效应”一般,对数学学习乃至数学思维的发展造成影响。适当的计算训练,对于提升学生计算能力、促进其思维的发展有着较好的推动作用。 Since the implementation of the new curriculum, computational teaching has undergone great changes. The reorientation of teaching value calculation and the reduction of calculation practice make many teachers ignore the improvement of students’ good computing habits and the practical calculation ability to a certain extent. The weakening of students’ computing abilities is like the “butterfly effect”, which has an impact on the development of mathematics learning and even mathematical thinking. Appropriate calculation and training, to enhance the ability of students to improve their thinking and development has a good role in promoting.
