This study’s purpose was to examine the self-efficacy of preservice teachers throughout an immersive learning semester and compare it with a control group. The study suggests that a community-based immersive program supports preservice teacher efficacy development within the dynamic cultural context of families and schools. The immersive learning participants’ (n = 32) teacher efficacy was assessed thrice and compared with a traditional on-campus program (n = 64). Using the Teacher Sense of Efficacy Scale, results revealed significant improvement in the Immersive group across time in all three areas (Engagement, Management, and Instruction). Comparison of net gains between groups suggests that an immersive and supportive environment promotes preservice teacher efficacy development even in the midst of a socio-cultural gap between preservice teachers and students.
