This document presents the progress and effort made in the design of a dialog system for the virtual characters in DynaLearn.
The main purpose of this system is to provide means by which the virtual characters can present relevant system knowledge to the learners in a pedagogically sound manner. After providing an overview of the role of dialogs in interactive learning environments we present the architecture of our approach and describe in detail the functionality of its three main components: Dialog Management, Verbalization and User Modeling.
