Pedagogically Asymmetric Elo Models for Multidimensional Adaptive Learning Systems

Adaptive learning systems commonly use psychometric models to estimate learner ability and task difficulty. Among the most widely used approaches are Item Response Theory (Harvey & Hammer, 1999) and modifications of the Elo rating system (Pelánek, 2016). These models typically assume a symmetric learner–task interactio...
