This study explored early childhood student teachers of color’s (ECSToCs) development of cultural competence during their fieldwork experience. Nine female students of color enrolled in an early childhood education fieldwork course participated in this study. Employing a qualitative research methods approach, we analyzed multiple data including students’ reflection papers on culture and diversity, teaching philosophy papers, interview transcripts, lesson plans on cultural diversity, and post-teaching reflection. The findings showed: (a) ECSToCs’ perceptions of culture were highly influenced by their lived experiences including their bilingual, bicultural, and schooling experiences; (b) ECSToCs’ awareness of and attitude toward diversity were implicated by their parents’ lived experiences and knowledge; and (c) they viewed culture as a pedagogical and methodological tool to guide their teaching practices, emphasizing asset-based approach. This study contributes to developing effective instructional strategies to elevate ECSToCs’ cultural competence in their teaching. (author abstract)
