你是不是在为排列组合的讲授而发愁呢?你的学生是不是在为这个知识点而大伤脑筋呢?我们都知道,排列组合作为高中代数课本的一个独立分支,因为极具抽象性而成为“教”与“学”的难点。有相当一部分题目教师很难用比较清晰简洁的语言讲给学生听,有的即使教师觉得讲清楚了,但是由于学生的认知水平、思维能力在一定程度上受到限制,到最后还是听得一头雾水,从而导致学生对题目一知半解,甚至觉得“云里雾里”。针对这一现象,我在日常教学过程中经过尝试,总结出一些个人经验,现在拿出来跟各位同行交流一下。
Are you fretting about arranging combinations? Are not your students brain-wrenching for this point of knowledge? We all know that permutations and combinations, as an independent branch of high school algebra textbooks, are highly abstract Become “teaching” and “learning” difficult.

In response to this phenomenon, I tried in the daily teaching process, summed up some personal experience, now come out to share with your colleagues.
