古希腊哲学家苏格拉底说过:“没有反思的人生是无意义的人生.”同样,不经过反思的解题是不完备的解题.反思,是对问题和问题解决的深层思考.解题反思的方法有多种,本文通过与学生的对话交流,探讨如何从简单的问题和方法开始反思,逐步获得更多的结论.师:我们先复习基本不等式a~2+b~2≥2ab①和~(a+b)/2≥(ab)~(1/2)(a,b∈(0,+∞))②,除了灵活运用外,我们还可以深入反思.生甲:这么简单的不等式,有什么好反
Socrates, the ancient Greek philosopher, said: “Life without reflection is meaningless life.” Similarly, the problem of reflection without reflection is an incomplete solution. Reflection is a deep reflection on the solution of problems and problems There are many ways to solve the problem of reflection, this article discusses how to start from simple questions and methods, and gradually get more conclusions through dialogues and conversations with students. Teacher: Let us first review the basic inequalities a ~ 2 + b ~ 2 ≥2ab① and ~ (a + b) / 2≥ (ab) ~ (1/2) (a, b∈ (0, + ∞)) ②, in addition to flexible use, we can also in-depth reflection. Simple inequality, what good anti
