Guiding Principle Cooperative, hands-on learning allows students to confront a range of topics with the perspective of their assigned country or organization. Through these experiences - during preparation, in committee sessions, and even in hallway caucuses - students develop an appreciation of differing viewpoints, experience the challenges of negotiation, see the rewards of cooperation, broaden their world view, and discover the human side of international relations and diplomacy.
