Heterogeneous online learning environments such as Go-Lab foster student-centered and exploratory STEM education through the promotion of Inquiry Learning. Although the learner is encouraged to create learning objects such as concept maps or hypotheses, the interpretation and reflection on them is complicated by differences in their form of representation. This work presents the ConceptCloud ap...

We investigated 28 learners’ postural patterns associated with naturally occurring episodes of boredom, flow/engagement, confusion, frustration, and delight during a tutoring session with AutoTutor, a dialoguebased intelligent tutoring system. Training and validation data were collected in a learning session with AutoTutor, after which the learners’ affective states (i.e., emotions) were rated ...
