近年来,高考对运算能力的考查在悄悄发生改变,即由“正确迅速的数式运算,变形能力”逐步转换到“对估算意识,估算能力”的考查.尤其今年的全国普通高等学校招生统一考试理科数学客观试题,充分体现了估算能力的灵活巧妙运用,展示了估算意识事半功倍的效果.
In recent years, the examination of the computational ability of the college entrance examination has quietly changed, that is, the “correct and rapid mathematical calculations and deformability” have gradually shifted to the “assessment of estimation consciousness and estimation ability.” The school entrance examination and examination of science mathematics objective test questions, fully embodies the flexible and clever use of the estimation ability, and shows the effect of estimating the consciousness with half the effort.
