This study reports the outcomes of undergraduate students completing a pilot Interdisciplinary Intensive Course Abroad (IICA) with a service learning component. The IICA model is comprised of a three-part sequence of study that includes a seven-week course on campus, followed by three weeks of study abroad, and a summative seven-week course back on campus. The additional summative component gives students the opportunity to bring together their newly acquired knowledge and skills, and to reflect on how to integrate these experiences in their future. The sequence integrates discipline-specific content studies with foreign language classes, and grounds them with a study abroad experience. A mixed-method design was used to measure students' development of language skills, understanding of multicultural education concepts, and intercultural skills. Primary data sources were pre/post-assessments, student field notes and reflections, and a post-course survey. Results indicated that students gained confidence in their Spanish skills and were likely to enroll in further Spanish courses, their ability to define multicultural education concepts increased, and service learning, homestays abroad, and their time in an indigenous reservation contributed to development of intercultural skills.
