This paper discusses the changing roles of tutors when engaging with e-learning. Understanding the importance of these roles and identifying necessary tutoring skills is paramount for the success of e-learning solutions. Since online tutors play a critical role in e-learning, as the main agents responsible for the delivery of the courses and the support of the learners, they must be equipped wi...

Much of the research exploring the features of speech that distinguish intelligibility ratings has focused on monologic speech production. This study considers whether the use of specific interactive features in task-based interaction influences interlocutors' ratings of intelligibility. Five dyads completed an information gap task and rated their partners' intelligibility following task comple...

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...

Research has shown that shared ethnicity between the agent and the user reflects in a positive perception of the agent's capabilities and provides motivation for learning tasks for students of color (Baylor, 2005; Nass et al., 2000). However, research has failed to examine what kinds of implementations of ped...
