根据数学课程标准的要求,在数的运算方面,要重视口算,加强估算,淡化笔算,学会使用计算器,鼓励算法多样化。淡化笔算的具体作法,一是引入计算器,用计算器代替一部分笔算,另一方面是降低笔算的要求。但从教学效果来看,计算器引入课堂,如果教师稍微控制不好就会影响学生计算的正确率,对学生的计算能力产生不同程度的负面影响。
According to the requirements of mathematics curriculum standards, in terms of number of operations, we should attach importance to port count, strengthen estimation, dilute the calculation, learn to use calculators, to encourage algorithm diversification. Desalination of the specific practice, one is the introduction of calculators, calculator instead of part of the pen calculation, on the other hand is to reduce the pen requirements. However, from the perspective of teaching effect, the calculator is introduced into the classroom. If the teacher is not well controlled, it will affect the accuracy of the students ’calculation, which will have different degrees of negative impact on the students’ computing abilities.
