“…In this method, the game engine monitors and records interaction between the learner and the game, generating a trace of actions performed by the learner during the play sessions and tracking a lot of different parameters in the game (start game, end game, quit game, phase changes, significant variables, time, performance, tasks completed, etc.). At the end of the game play, these traces can be delivered to a group of experts or automated systems in order to identify what information can be extracted from these traces and infer a lot of useful information for modelling purposes (Stathacopoulou et al, 2007;Bouvier et al, 2013a;Bouvier et al, 2013b). For example, learner's learning style was modelled in (Stathacopoulou et al, 2007) by monitoring learner's actions over time, where each response such as a keystroke, mouse move or drag was timed and recorded.…”
