We are teachers. We have to think on our feet at every moment of the day. It’s what we do. It’s part of our job. Just like actors on the screen, good teachers make good teaching look effortless. It looks so easy that a passerby might even think, “I could do that!” But honestly, it takes a lot of work to make the art of teaching appear almost effortless. The power of good instruction comes from tapping into every opportunity to engage students.
