This paper explores equity challenges common to short-term cross-cultural research partnerships. We focus on a project-based activity in which U.S. undergraduate students and college faculty taught middle-school students in Goa, India how to make podcasts about complex environmental problems. Project team members conducted a collaborative auto-ethnography focused on questions of power, leadership, collaboration, and equity, and examined exit interview photo elicitation data to identify the core challenges of ethical and equitable short-term cross-cultural research and programming. Our use of photographs as conversation prompts helped to highlight contradictions and asymmetries along axes of power, cultural imperialism, knower-knowledge, age, race/ethnicity, social class, and gender. We reflect on possibilities for educational research that rejects a "voluntourism" model and moves, if imperfectly, toward more equitable international collaborations.
