The conventional wisdom about political science international education assumes that students choose between short "island" study abroad programs that are accessible but have only superficial impact, and longer immersion programs, achieving a greater effect. This article argues that well-designed study abroad programs can combine the best of both models to achieve significant impact even in a short program. It proposes a "bridge model" for reconceptualizing study abroad not as a discrete event with more or less impact on student learning, but as a key intervention that furthers a student's overall development within an internationalized curriculum. The article examines the case of a peacebuilding study abroad program in Ecuador. It measures alumni perceptions of impact, objective outcomes, and alumni network development. The key finding is that solid program design and structured cross-cultural interaction produces the type of long-term effect and networks traditionally associated with immersion programs.T he emphasis within political science on student civic engagement and internationalization of the curriculum during the past two decades (Battistoni 1997; Jacoby and Brown 2009) has coincided with a drastic increase in the number and diversity of international academic experiences that go beyond the traditional "island" model of study abroad. Among these, experiential programs designed to teach international conflict resolution and peace studies have proliferated, combining theoretical training in conflict analysis and peace studies with a practical application of mediation and negotiation skills, and, sometimes, international development (Fowler 2005). 1 The growth of these programs raises a broader question about the effectiveness of this mixed experiential pedagogy not only on student learning and attitudes but also on concrete educational and professional outcomes.This article argues that well-designed shortterm study abroad programs can achieve significant impact traditionally associated with semester or longer immersion programs but accomplishing this in a more accessible way for a broader and more diverse student population. The article proposes a framework for understanding short-term programs as key interventions that "bridge" different elements of a student's overall internationalized education. The empirical portion of the article analyzes the case of the Peacebuilding and Development Study Abroad Program in Ecuador (PADSAPE), a short-term program with local cultural immersion and experiential-learning components. It explores the relationship between student participation in PADSAPE and longer-term personal development and impact, including the development of useful skills, subsequent in-depth international experiences, and transnational professional networks.The analysis reveals that the value of short-term programs is not only students' immediate knowledge and skills transfer, but also their ability to bridge between past international affairs academic preparation and future in-depth practi...
