Immersive learning technologies offer K–12 English learners simulated contexts for language acquisition through virtual interactions, influencing learner attitudes and enhancing cross-curricular skills. While past literature reviews have explored learners’ English skills and emotions, few have delved into the learning effectiveness of immersive technologies for K–12 students. This systematic review analyzed 33 studies from 2012 to 2021, focusing on research designs, the role of immersive technologies in English learning, and the theoretical underpinnings of these studies. Results highlight the methods used to gauge learning effectiveness, the ways immersive technologies bolster learners’ attitudes and skills, and a noticeable gap in theoretical grounding. Recommendations for future research are provided.
