Abstract. Affective states play a significant role in students' learning behaviour. Positive affective states can enhance learning, while negative ones can inhibit it. This paper describes the development of an affective state reasoner that is able to adapt the feedback type according to students' affective states in order to evoke positive affective states and as such improve their learning experience. The reasoner relies on a dynamic Bayesian network trained with data gathered in a series of ecologically valid Wizard-of-Oz studies, where the effect of feedback on students' affective states was investigated.
Grawemeyer et al. REF developed an affective state reasoner to adapt different types of feedback to a learner's affective state during their interaction with a learning environment.
