While video permits rich activity capture, it provides no support for quickly seeing activity patterns that can assist learning. In contrast, position tracking systems permit the automated modelling of spatial behaviour, opening new possibilities for feedback.

To fill in this gap, we evaluate ClassBeacons, a system that uses spatially distributed lamps to depict teachers' ongoing performance on how they have divided their time and attention over students in the classroom.
