In a rapidly changing world, many decisions are taken in conditions of stress and tight time pressure. Often, the results are less than optimal. Against this background, the goal of DECIDE-IT is to create an innovative, easily used teaching methodology based on a game learning approach . The project will take an existing multiplayer online serious game (DREAD-ED) originally designed to train personnel involved in the management of natural and industrial disasters, and adapt it for use in management training. DECIDE-IT’s educational strategy will be experience-based, simulating stressful situations where learners can develop and practice decision-making skills. To this end the project will adopt a blended approach, mixing classical training along with tutor-supervised virtual role-playing in an online 2D environment.
