数学课程标准专门提出了要培养学生的运算能力,它也是数学课程标准中的十大关键词。新课程不再纯粹地为计算而计算,往往通过具体的情境,让学生在解决现实问题中落实运算能力的培养。但是这样的改变,很多老师不适应,他们抱怨这样冲淡了计算味,从而影响到学生运算能力的培养。为此,如何开展有效的运算教学,提高学生的运算能力成为一线教师思考的问题。笔者在教学实践中,以处理好三个关系为切入口,对提高运算教学的有效性作了些思考。
Mathematics curriculum standards specifically put forward to develop students’ computing power, it is also the ten key words in mathematics curriculum standards. The new curriculum is no longer calculated purely for the calculation, often through concrete situations, so that students can solve the practical problems in the implementation of computing power. But such a change, many teachers do not adapt, they complain that this dilute the calculation of taste, thus affecting the ability of students to develop. To this end, how to carry out effective computing teaching and improve students’ computing power has become a problem that front-line teachers think. In the teaching practice, the author takes the handling of the three relations as the starting point and makes some reflections on how to improve the teaching efficiency of computing.
