This article reports on a preliminary finding of sociocultural adaptation experienced by two pre-service teachers (PSTs) during a service-learning program. They wrote photo-voices, a photo-mediated self-reflection, to share how they adapted to the sociocultural life of their first two-week service learning. Using the U-heuristic analysis model, this study found three contributing factors that helped them build sociocultural adaptation skills: peer support, self-motivation, and assimilation. Meanwhile, the PSTs' photo-voices also shared their concern when maintaining sociocultural engagement, such as language differences and indigenous traditions. The findings suggest intercultural awareness development of PSTs to build sociocultural adaptation in the context of service learning.
