Background: Concerns have been raised about the inconsistency and quality of pre-service teacher preparation, especially in reading literacy. Mixed-reality simulations can potentially revolutionise initial teacher education by offering realistic, risk-free practice opportunities to master reading practices. Objectives: This study explores pre-service teachers' perceptions of: (1) interacting with avatars; (2) teaching core reading skills, particularly eliciting background information on informational text; and (3) using an action review cycle within a mixed-reality simulation environment. Method: A qualitative exploratory case study design was used in this study in order to document pre-service teachers' perceptions of engaging within a mixed-reality simulation environment. A purposive sampling strategy was used to select participants for this study. Data were analysed using thematic analysis. Results: Findings reveal that pre-service teachers valued interacting with the avatars and appreciated the unique focus on eliciting learners' background knowledge, a core reading practice. They typically teach full lessons with limited genuine engagement during microteaching opportunities, making this an interesting experience. They highlighted the mixed-reality simulation's features, such as pausing, redoing, and receiving immediate feedback. The simulator allowed them to concentrate on skill mastery rather than staging lessons for grades. Conclusion: This study concludes that pre-service teachers' skill development benefits from deliberate practice opportunities designed to enhance complex skills. Mixed-reality simulations could reshape how student teachers are prepared for reading instruction. Contributions: This research contributes to the understanding of pre-service teachers' perspectives on teaching core reading practices in a mixed-reality simulation environment.
