This systematic literature review explores the impact of Virtual Reality (VR) on STEM education, focusing on the enhancement of student learning outcomes. Our findings reveal that VR's immersive and interactive features significantly improve student understanding, retention, and engagement. Key features of effective VR applications include immersive simulations and interactive experiences, which enhance the learning of complex concepts. However, this systematic literature review highlights a significant gap in studies focused on English Language Learners (ELLs), a group that could greatly benefit from VR's tailored educational experiences. The review emphasizes the importance of professional development for educators to effectively integrate VR technology. The findings advocate for further research and the development of VR applications aimed at creating more inclusive and equitable STEM learning environments, particularly for English Language Learners.
