A game-based animation tool to support the teaching of formal reasoning Resumo: When teaching formal reasoning in Computer Science it is challenging to find compelling practical examples to motivate the students. We introduce a system to provide students with animations in 3D virtual environments of the interactions of agents, in which the interaction protocols and the behavior of the agents are specified as logical theories. The system has been primarily designed as a teaching aid for undergraduate students enrolled in disciplines such as Artificial Intelligence and Formal Logics. A simulation of the pathfinding problem will be demonstrated during the presentation.
