Impact of Adaptive Educational System Behaviour on Student Motivation

Abstract. In this work we try to connect research on student model-ing and student motivation, particularly on the relation between task difficulty and engagement. We perform experiments within widely used adaptive practice system for geography learning. The results document the impact of the choice of a question construction algorithm and target difficulty on student perception of question suitability and on their will-ingness to use the system. We also propose and evaluate a mechanism for a dynamic difficulty adjustment.
