The American Political Science Association is currently calling for paper and panel proposals for its annual Teaching & Learning Conference, to be held  17-19 February 2012 in Washington DC. As always, the TLC includes a track on simulations and roleplay:

Simulations and Role Play
Simulations and role play exercises help political scientists and students model the decision making processes of real-world political actors. Examples of these teaching techniques and strategies include Model United Nations, Model European Union, in-class self designed simulations, and on-line role playing exercises. Papers in this track will address such topics as: in what way can simulations and role-play expand student learning opportunities in political science? Which formats are most effective? and How do we measure the effectiveness of simulations?

Proposals are due on or before September 23—you will find more information at the first link above.
