How do preservice teachers with low and high teacher self-efficacy respond when instructing a simulated classroom with challenging behaviors? This research study identified the responses of four preservice teachers as well as examined their teacher self-efficacy and teacher anxiety measures following their participation using Teach Live™, an augmented reality teacher preparation tool. Researchers gained insight into preservice teachers' self-efficacy and their responses to simulated challenging classroom behaviors. Following participation with the augmented reality teacher preparation tool, 75% of participants felt less confident in their teaching ability following hurtful comments from the avatars. Additionally, 75% of participants also reported that they felt nervous as the avatar misbehaviors escalated. However, all participants felt that this technology provides a useful tool for preservice teachers to gain teaching experience.
