International travel has long been considered a key pedagogical strategy for global learning. Yet very little is known about whether study-abroad experiences increase students' awareness of the impact of tourism as a global phenomenon. In this study, we assessed students' learning through a content analysis of their journals and final essays from a short-term study-abroad course that used key concepts from the sociology of tourism to explore the impact of tourism in a developing country. Findings demonstrate how thinking sociologically about travel and tourism enabled students to look "behind the scenes," fostered critical-thinking skills, helped in their self-assessment of ethnocentrism, and promoted a sense of global responsibility. We also discuss areas that merit further pedagogical attention, particularly when students struggle to unlearn preconceived ideas about poverty and inequality or resort to overgeneralizations when thinking comparatively.
