Integrated characters with dialogue and tutorial strategies

In this deliverable, we introduce three new virtual character support types (Critic, Quiz and Diagnosis) which are linked to different kinds of conceptual knowledge (such as semantic feedback or multiple choice questions) generated within the DynaLearn software. We show how this knowledge is extracted and transformed into character-specific dialogs that are presented by the virtual characters but also encourage the learner to engage and participate. For this process, we rely on the architecture and dialog management system developed in earlier deliverables. Finally, we investigate how different characters and support types can be combined with each other to from integrated dialogs to even further support and engage learners

In this document we present two different use cases of the DynaLearn software which involve virtual characters: The Teachable Agent and the Basic Help. We elaborate on how the necessary knowledge for these use cases is extracted from the CM component, how it is represented and how it is turned into presentations by the virtual characters that are engaging and helpful for the learners. We also describe how the different parts of the dialog system presented in Deliverable 5.2 aid us in achieving this task

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
