Teaching a complex skill set, such as leadership, requires interaction with realistic environments. LEED (Leadership Education through Evolutionary Design) is a training simulation in which platoon leaders learn and practice leadership skills through interactive dramas related to crowd management. LEED uses Interactive Pedagogical Drama and autonomous agents to create interactive instruction. The learner interacts with simulated characters in a story-based setting where the plot changes as the learner's actions affect the story. LEED builds on previous research using an intelligent agent-based simulation infrastructure to model role-playing characters simulating crowd behavior and military responses during MOUT (Military Operations on Urban Terrain) operations. This paper will describe the use of agent-based crowd simulation architecture as an instructional medium, as well as provide a detailed description of the instructional design.
