目前,计算机的普及越来越广,但是小学生的计算能力却没有随着科技的进步而有所发展,反而小学生运算能力的状况是每况愈下。有的学生不明算理,机械地照搬公式;有的则是不顾运算结果,盲目推演,缺乏合理选择简捷运算途径的意识;也有的学生对提高运算能力缺乏足够的重视,他们总是把“粗心”“ At present, the popularization of computers is more and more widespread. However, the computing abilities of pupils have not developed along with the progress of science and technology. Instead, the computing power of pupils is deteriorating. Some students do not understand reasonably and mechanically copy the formula; others ignore the result of the calculation, blindly deduce the lack of awareness of the simple choice of computing route. Some students lack sufficient attention to the ability to improve computing power. They always put ” careless“”
