This study investigates Turkish pre-service teachers' experiences related to a two-month international teaching and cultural experience in the United States of America. In total, 289 graduate students from Turkey participated in a collaborative project from 2001 to 2010. The experience included an orientation week, six weeks of student teaching in a high school, seminars and projects at Iowa State University and cultural visits. The data were collected through a pre-service teacher questionnaire and their reflective journals. The results showed that pre-service teachers perceived the international teaching experience helped them develop professionally and personally. Through cross-cultural exchanges with their mentors along with other students and their community, the pre-service teachers expanded their knowledge of a new culture and adapted to a new working environment.
