In an age when artificial intelligence can produce curriculum in less time than it takes to unlock a phone, an older practice is becoming newly essential: teaching by walking around.

When an instructor moves through a lab or class, learning becomes tactile. A cable isn’t just coiled; it reveals confidence or hesitation. A pause before pressing record says more about readiness than any rubric. And the student half-hiding behind a phone isn’t necessarily disengaged—they may be unsure, overwhelmed, or taking cover. These signals are almost impossible to see from the front of the room or a laptop webcam. They appear only when you’re close.

Peter Drucker offers a useful lens: the person closest to the problem is the one best suited to solve it. On a shop floor, the foreperson who walks the corridor doesn’t need a report to know something’s off—they hear the change in a machine’s rhythm. Their proximity is their advantage.

Education works the same way. Walking around is a reminder that learning is physical, observational, and relational. No automated assessment can match the accuracy of noticing how someone handles a tool or fits within a team. Mastery is rarely spoken; it’s expressed in posture, timing, and the small adjustments made without thinking.

AI, for all its computational brilliance, remains one step removed from the real moment. It can generate structure, pattern, and polish, but it can’t sense friction or interpret the glance that says, I almost have this – don’t give up on me. AI can’t tell the difference between distraction and self-protection. And it can’t replace the situational awareness that appears when an instructor slips, briefly, into the current of a student’s work—near enough to catch the small signals a learner doesn’t yet notice in themselves.

Teaching by walking around isn’t nostalgia. It’s a counterbalance—a quiet technology of attention in a time when attention is easily outsourced. It reminds us that the closest observer often sees the clearest path forward, and that the most important data in any classroom will never appear on a screen.
