Main Theme of Summer School 2009 “Simulation Game design for education & training” As Klabbers has pointed out, design - broadly conceived - aims at implementing courses of action with the purpose to change existing (dysfunctional) situations into preferred ones. He distinguishes two levels of design: “design-in-the-small” and “design-in-the-large.” Design-in-the-large offers a basis to various forms of consulting, training and education in the attempt to foster new ways of thinking and acting and to change social systems. Design-in-the-small produces gaming/simulations (gaming artifacts) as interventions and interactive learning environments to enhance education & training. Used with that goal in mind, they contribute to the “design-in the-large” process of social systems. This Summerschool is about the design of simulation games for learning. Lectures of teachers will be about different methods of game design for education and training, on the use and facilitation of simulation games particularly in educational settings (primary, secondary, tertiary), professional training, and teacher training, on pedagogical conditions and learning environment settings for learning from simulation games, on debriefing and transfer between game and reality and on assessment with games and evaluation of effects of gaming simulation. In interactive team-work (coached by the teachers) participants will develop prototype games for education and training.
