缘于对“算法多样化”的热衷,“你喜欢用什么方法计算就用什么方法计算”一度成为数学课堂中的一句时髦话语。在多数课堂上教师花费大部分时间引导各种算法,然后一律称好,最后让学生以自己喜欢的方法计算结果。课标提倡不急于优化,有些教师干脆不优化了。 Due to the enthusiasm for “diversity of algorithms”, “what method do you like to use to calculate?” Was once a fashionable phrase in maths class. In most classes, the teacher spends most of his time directing various algorithms, and then he or she will be good at all, and finally letting the student calculate the result the way he likes. Class advocates do not rush to optimize, some teachers simply do not optimize.
