🧪 Education Online Learning Simulation

This simulator models what actually happens inside a live online-learning session: every tile in the 3D grid is one remote student, and its colour and height track a personal attention curve that decays exponentially toward a boredom floor between engaging events, exactly as sustained-attention research describes vigilance decay in unbroken tasks. Quiz checkpoints re-engage the class through the testing effect but can also tip a deeply disengaged student into leaving the call — a stand-in for real online-course drop-off — while breaks restore attention and claw back the slow "screen fatigue" that erodes the class's achievable ceiling over a long session. Tune class size, checkpoint frequency and session speed, trigger a break on demand, and watch class-average attention, predicted quiz score and cumulative drop-out update live, making the case for short, interactive sessions over long uninterrupted lectures.
