Prime Climb is an educational game that provides individualized support for learning number factorization skills. This support is delivered by a pedagogical agent in the form of hints based on a model of student learning. Previous studies with Prime Climb indicated that students may not always be paying attentions to the hints, even when they are justified. In this paper we discuss preliminary ...

This work takes place in the framework of the design of a training environment using virtual reality. In this context, we defend the thesis that it is possible to integrate a generic and adaptive intelligent tutoring system (called PEGASE) in a virtual environment, in order to provide pedagogical aid for the learner and pedagogical assistance for the trainer. Our proposal is a multi-agent syste...

This paper discusses how mediation strategies can be used to design a pedagogical agent integrated to a text mining tool to promote collaborative work in academic reading and writing activities. The agent uses the Artificial Intelligence Markup Language (AIML) to communicate with students, while its text mining features enables it to keep track of what is being produced collaboratively. Mediati...

Building pedagogical applications in virtual worlds is a multi-disciplinary endeavor that involves learning theories, application development framework, and mediated communication theories. This paper presents a project that integrates game-based learning, multi-agent system architecture (MAS), and the theory of Transformed Social Interaction (TSI), The project implements a group of engaging, a...

ZHANG, WEI. Multimodal Pedagogical Planning for 3D Learning Environments A Unified Framework. (Under the Direction of Dr. James C. Lester and Dr. R. Michael Young.) Pedagogical planning lies at the heart of knowledge-based learning environments. In recent years, multimodality and authoring have become key issues in the creating of learning environments. The purpose of this research has been to ...

Animated pedagogical agents are lifelike virtual characters designed to augment learning. A review of developmental psychology literature led to the hypothesis that the temporal contingency of such agents would promote human learning. We developed a Pedagogical Agent with Gaze Interaction (PAGI), an experimental animated pedagogical agent that engages in gaze interaction with students. In this ...

This paper introduces the learning environment MathGirls for high school girls learning fundamentals of algebra. Grounded in social cognitive theories of learning, MathGirls utilizes pedagogical agents to create a girl-friendly virtual learning environment. The design constituents of pedagogical agents are reviewed. These constituents are likely to influence building agent/learner relations. Th...

Pedagogical agents (PAs) have the ability to scaffold and regulate students’ learning about complex topics while using intelligent tutoring systems (ITSs). Research on ITSs predominantly focuses on the impact that these systems have on overall learning, while the specific components of humanITS interaction, such as student-PA dialogue within the system, are given little attention. One hundred u...

The aim of this study was to empirically evaluate an embodied conversational agent called GRETA in an effort to answer two main questions: (1) What are the benefits (and costs) of presenting information via an animated agent, with certain characteristics, in a ‘persuasion’ task, compared to other forms of display? (2) How important is it that emotional expressions are added in a way that is con...

Interactions between learners and pedagogical agents may take on a more or less social tone, dependent on many possible factors. We investigate the effects of manipulating agent dialog on learner-agent interpersonal relations, which is hypothesized to promote learning. We have implemented our model of social instructional dialog (SID) in an agent in a virtual learning environment for instructin...
