Due to the constant migration of diverse populations, multicultural communities are developing across North America. As a result, multi-culturally diverse classrooms are multiplying (Allen et al., 2017). Our pre-service teachers must be multi-culturally prepared to enter diverse classrooms and effectively teach students without implicit bias (Ladson-Billings, 1995; Banks, 2010; Paris, 2017). Pre-service teachers' identity and cultural competence should be prioritized in teacher preparation programs. Using Latino/a Critical Race Theory (LatCrit), Practice-Based Learning, and Teacher Identity as conceptual frameworks, this study will answer how Mixed Reality Simulation (MRS) may be used as a teacher preparation tool (Aguilar & Flores, 2022) to develop the cultural competence and teacher identity of Hispanic pre-service elementary bilingual teachers. The MRSs were also used to explore what pedagogical practices (i.e., translanguaging, translating) pre-service teachers naturally gravitate to when confronted with an emergent bilingual student. This study used a case study approach to understand the perspectives of these pre-service teachers on multicultural education and linguistic ideologies. This study content analysis to analyze participant interviews, reflection journals, and observations of MRS sessions.
