This reprinting of Intercultural Development in Global Service-Learning makes this important research available for service-learning and study abroad practitioners. This mixed-methods study utilized the Intercultural Development Inventory (IDI v3) and in-depth student interviews to understand whether and how students experience intercultural development. Despite the small sample size, there are significant results (using the Wilcoxon signed ranks test). Iterative coding yielded three major themes, including the reasons for changes in intercultural development, the results of these changes, and the experience of those changes. These themes are fully developed in the text, and provide important information for practitioners of international education. Committee members include Eric Harman, Peggy Pusch, and Kent Warren.
