This work studied the Politeness Effect in a foreign language intelligent tutoring system, and provided further evidence that tutorial feedback with socially intelligent strategies can influence motivation and learning outcomes.

We illustrate a pedagogical metadata model (IMATI-ITD pedagogical metadata model) that captures didactic features of LOs according to the view of the education world. This model allows to describe a variety of contexts and can be effectively instantiated in many specific educational situations, thus combining generality with flexibility features.

We present a study that addressed if providing students with scaffolding about how to “integrate” science text and animations impacts content learning. Scaffolding was delivered by a pedagogical agent and driven by student’s eye gaze movements (compared to controls). We hypothesized that students in the pedagogical agent condition would engage in richer learning as evidence by a more “integrate...

We introduce the semi-automatic assessment model of student texts. This paper concentrates on the pedagogical foundations of the model.
