Photo-elicitation interviewing (PEI) is a technique in which photographs are used within an interview context. In this paper, I describe the use of PEI as a means to examine the development of bicultural identity and sense of school belongingness of sixth-grade Latinx students in mainstream English-only (EO) and two-way immersion (TWI) elementary school programs at one school in the southwestern United States. Findings indicate (a) biculturalism is expressed differently by students based on their participation in the TWI or EO program and (b) overt displays of bicultural identity or mainstream cultural expectations affect students' sense of school belongingness in and out of the school setting. I also examine the advantages and limitations of photography and photo-elicitation interviews. While not without its limitations, results from this study suggest that PEI is an appropriate method to use when studying complex concepts, such as bicultural identity, with elementary-aged students.
