计算能力是小学生数学学习的基本能力,是影响学生学习成绩的重要方面。然而计算能力的培养往往被人们忽视,往往理解为:只要多做、多练、细心写,就能做正确的片面理解。家长认为:孩子的计算错误是一时的粗心造成,只要下次细心就行了。大多数教师认为:计算只要多做多练,熟能生巧,学生的计算能力就会提高了。然而在实践中我们往往发现:该做的练习都做了,类似的计算题做了好多遍,但在综合练习或评价测试中学生的计算还是存在较多错误。沉下心来细细分析, Computational ability is the basic ability of primary school mathematics learning, is an important aspect that affects students’ academic performance. However, the cultivation of computing power is often overlooked by people, often understood as: as long as more, more practice, careful writing, you can do the correct one-sided understanding. Parents think: children’s calculation error is a temporary carelessness, as long as the next carefully. Most teachers think that as long as the calculation is done more and more practiced, the calculation ability of the students will be improved. However, in practice, we often find that all the exercises should be done. Similar calculation questions have been done many times, but there are still many mistakes in the calculation of students in the comprehensive practice or evaluation test. Sink down carefully analyze,
