We are all students and learners and teachers. I write this in tribute to my greatest teacher from a student's perspective. Maybe you will stop to think of a favorite teacher, mentor or role model, and perhaps even reach out and say hello to them.

"Question authority": It means having a healthy skepticism about the world around us. As I often tell my students, there is no absolute social reality -- we perceive reality differently based on who and what surrounds us. And my reality may not always match yours.

As a teacher, I have long advised against using grades as motivation for learning. Well yes, I suppose it works, but I don't like it that it works.

Our campuses should be places where diversity leads to learning as students come to see differences among people as a deep resource for solving problems and seeking opportunities. Online education can complement this educational environment. But it does not replace the need for it.
