文档介绍：Pundit: An Animated Pedagogical Agent in Web-based Intelligent Learning Environment for Digital System (WILEDS)
(作者:___________单位: ___________邮编: ___________)
Animated pedagogical agents are life-like characters used as cognitive tools to support student learning. Pedagogical agents are better substitutes for the expert/tutor module of a traditional intelligent tutoring system as they provide sophisticated, real-time problem-solving advice with strong visual appeal that make learning more engaging and effective. In addition to this, animated pedagogical agents provide another important benefit: motivation. In a multi-agent environment, different agents are used for different tasks. But the main goal of a pedagogical agent is to perform a given tutoring function for the student’s benefit. This paper presents a brief introduction of different types of agents that are used for learning and gives a survey on current developments in this field. This paper also describes the architecture and roles of an animated agent called “Pundit” which has been developed for Web-based Intelligent Learning Environment for Digital Systems (WILEDS).

1 Introduction: Intelligent Tutoring Systems (ITS) plex systems that involve several different types of expertise: knowledge on the subject matter, knowledge on the learner’s knowledge, pedagogical expertise, etc [Frasson, Mengelle A?meur 1997]. All these knowledge need to be improved in order to be adapted to the learner and the different learning situation. To make this improvement, intelligent agents are introduced which represent a new generation of puter interface (HCI) design and are reactive, instructable, adaptable and cognitive. Animated pedagogical agents [André, Rist Müller 1997; Johnson, Shaw Ganeshan1998; Lester Stone 1997; Piesk Trogemann 1998; Sch?ch, Specht Weber 1998] are life-like autonomous agents that facilitate human learning by interacting with learners an
