A major issue in Intelligent Tutoring Systems is off-task student behavior, especially performance-based gaming, where students systematically exploit tutor behavior in order to advance through a curriculum quickly and easily, with as little active thought directed at the educational content as possible. The goal of this research was to develop a passive visual indicator to deter and prevent off-task gaming behavior without active intervention, via graphical feedback to the student and teachers. Traditional active intervention approaches were also constructed for comparison purposes. Our passive graphical intervention has been well received by teachers, and results suggest that this technique is effective at reducing off-task gaming behavior.
