Matt Owsley knows a thing or two about how students behave. That’s because this Scottsdale, Arizona, principal has seen a thing or two as he pushes his rolling desk around the Black Mountain Elementary School campus.

“I kept hearing about these ideas—to be present—and what it does culturally for your campus and how it helps behavior,” Owsley said. But a desk (and stool) on wheels, complete with his nameplate? Claiming temporary office space in the cafeteria, on the playground or in a dance class? Why not, thought Owsley. Why not try something new, fun and unexpected to be visible.
