As a teacher, I often expect my students to think critically. If you're a teacher I bet you expect the same.
As a parent, you wish for your kids to be able to critically evaluate the choices an important situation offers to make the smart, most beneficial decision. I know I do and while I realize my son and my students will not always make the best decision in every situation, I want them to be equipped with the tools that increase their chances.
Critical thinking is such a tool.
It can, and perhaps should be applied in both personal and professional life.
But in school, critical thinking is expected but not taught explicitly. Just do it works for a shoe brand but rarely for people....
