Abstract

This experiment has recently begun. The hypothesis is that errors during learning reduce performance through causing some sort of interference effect. Essentially the question is if you get item A wrong at time t, does that effect the chance of getting B wrong at time t+1. If such effects occur then the model of practice used for optimized scheduling will need to be revised to be more accurate. Such an improvement in accuracy should then translate to increased gains for students that have practice controlled by the model.
