The purpose of this research was to identify how students used social media during their experience with study abroad programs that focus on social and environmental sustainability. Key research questions included: Did students and program faculty directors perceive social media as beneficial or challenging to program goal? How did social media contribute to the overall learning process? How can this knowledge inform the design and implementation of future study abroad experiences? Surveys were conducted with students participating in three study abroad programs in three countries with varying levels of internet access. We found that most students used social media as a familiar support system to help acclimate to a foreign land, through the formation of cohesive peer groups and establishment of communication channels with family and friends. However, both students and program directors acknowledged the challenges of social media dependency. We conclude that judicious use of social media, when coupled with conscious immersion into the local environment and culture can enhance study abroad programs; and offer suggestions for future program planning.
