Classroom management is rarely about any single rule โ it's the interaction of clear expectations, positive reinforcement and predictable routines that keeps a room of students engaged. This simulator visualizes that interaction directly: 24 students sit at desks in a 3D classroom, each independently drifting between on-task, distracted and disruptive states based on a shared engagement score built from three tunable levers. Turn any lever down and watch disruption spread even while the others stay high; click "Teacher intervenes" to see how a direct redirection helps one student without fixing the underlying engagement level.
