In this study, the researchers used qualitative surveys to explore potential teaching candidates' preliminary perceptions of self as teacher and examine how roles are identified, defined and constructed in the context of a tutoring lab that provides support to English Language Learners. Prospective candidates' perceptions of their tutees, children whose cultural identities and backgrounds differ from their own, are also examined. Findings indicate participants' teaching identities and conceptualizations of their roles as teachers became more specific and elaborated over the course of the semester. Additionally, the significance of multiple practicum experiences in diverse settings for ongoing identity development and for developing knowledge about culturally and linguistically diverse school children was also clear.
