Dynamically Sequencing an Animated Pedagogical Agent

One of the most promising opportunities introduced by rapid advances in knowledge-based learning environments and multimedia technologies is the possibility of creating animated pedagogical agents. These agents should exhibit three properties: timely domain coverage (they should clearly communicate fundamental concepts and relationships within the allotted time) contextuality (they should provide explanations in appropriate problem-solving contexts) and continuity (their activities and utterances should be pedagogically, visually, and aurally coherent). We have developed the coherence-structured behavior space approach to creating animated pedagogical agents. This is a two-step approach. First, we design a behavior space of animation and audio segments that are structured by prerequisite relationships and a continuity metric. Second, we navigate coherent paths through the space to dynamically sequence behaviors. This creates seamless global behaviors that communicate fundamental knowl...
