In these often complex situations (action-oriented), the analysis of the interactions that take place provide a starting point for the evaluation of learning progress during the session. In this context, a cognitive-oriented interaction taxonomy was developed for the classification of the interactions, in which there existed a primary requirement for the subject to deal with the interaction at hand utilising a particular cognitive ability. For example, the subject was to solve a multiple-choice-question based on the contents of a slide previously shown by selecting one of the items. In order to do so, the subject must interact synchronously with a pattern that requires to remember factual knowledge in order to deal with the interaction.
