I’ve been inspired by a recent reminder of the old story about Hemingway and how he was asked to write a complete novel in only six words. I immediately began thinking about how I could distill advice to educators down to just six words. What can you say about assessment (as opposed to grading), instructional design, program evaluation, classroom management, and so on in just six words?

My first shot: Don’t solve problems students don’t have.

What six-word guidance do you have for educational best practices?
