This mixed-methods study explored the impacts of a semester-long technology professional development for secondary school international teachers from developing nations around the world. We used (a) a survey approach to examine international teachers' perceived technology integration abilities using the technological pedagogical content knowledge (TPACK) framework and (b) a design task to understand their rationale behind technology integration decisions. As a group (N = 16), international teachers reported increased abilities in all TPACK domains. Qualitative analysis of their rationales revealed that though teachers learned to consider the affordances of technology, technology access issues were pivotal in their choice and use of technology in instruction planning. With education becoming increasingly global, the study has implications for the motivation and design of technology professional development programs for international teachers.
