I’ve been reading some old issues of The Teaching Professor newsletter and ran across a lovely piece by William Reinsmith on learning moments. He’s writing about those times when students get it, when something turns the lights on and they glow with understanding. It may be a moment when they finally figure out how to do so something—a long elusive skill or a solution to a problem. Other times it’s a moment of insight, often a possibility or explanation that had never crossed their minds, or a set of ideas that come together and create a new perspective on a familiar issue.
