高考数学试题对高中生的计算能力要求很高,特别是解析几何题更能体现学生计算能力的高低。不过,计算能力并不是单纯体现在算数上,更是“算法”的体现。优秀的“算法”不仅体现在计算量的大小上,更是思想方法与基础知识熟练程度的体现,也就是说,要想在高考中胜出,就要努力成为一名有思想的计算者。以下就2017年全国高考理科数学Ⅰ卷第20题第二问的几种不同解法谈谈我的想法。 College entrance math test of high school students ’computational skills demanding, in particular, analytical geometry problems can better reflect the level of students’ computing power. However, the computing power is not simply reflected in the arithmetic, but also “algorithm ” embodiment. Outstanding “algorithm ” is not only reflected in the amount of calculation, but also reflects the proficiency of the method and basic knowledge, that is, in order to win the college entrance examination, we must strive to become a thoughtful calculator . Following on 2017 National Science Entrance Examination Mathematics Volume I Question 20 second question several different ways to talk about my idea.
