课改之前小学计算教学过多强调大题量训练,过多关注笔算教学,过多关注计算结果,计算教学枯燥、乏味;课改之初又过分强调算法多样化、算法自主探究、算理自主体验,减少了必要的练习,导致学生计算能力的整体下降,影响到学生解决问题能力的提高。如何提高当前计算教学的有效性,笔者以为要做好以下几点。 Before the curriculum reform, there were too many teaching emphasis on the teaching of large quantities, too much attention to the teaching of pen calculation, too much attention to the calculation results, calculation of teaching boring and boring. At the beginning of the curriculum reform, too much emphasis was placed on the diversification of algorithms, autonomous exploration of algorithms and autonomous computing Experience, reduce the necessary exercises, resulting in an overall decline in students ’computing power, affecting students’ ability to solve problems. How to improve the effectiveness of the current computing teaching, I think to do the following points.
