Education in Northern Nigeria, particularly in Sokoto State, is confronted by a multidimensional crisis rooted in chronic insecurity, severe infrastructural deficits, and acute shortages of instructional resources, all of which disproportionately impair the delivery of Science, Technology, Engineering, and Mathematics (STEM) subjects. These subjects demand hands-on, inquiry-based, and visually engaging pedagogical environments that conventional lecture-based instruction cannot sustain under such conditions. Extended Reality (XR) encompassing Virtual Reality (VR), Augmented Reality (AR), and Mixed Reality (MR) is increasingly recognised as a transformative educational technology capable of addressing these systemic gaps. This theoretical and contextual analysis synthesises empirical evidence, policy frameworks, and pedagogical theory to establish XR as a viable, scalable tool for delivering standardised, immersive, and high-quality STEM instruction to at-risk learners in conflict-affected settings. Anchored in Social Cognitive Theory (SCT), the paper demonstrates that XR technologies provide safe, consistent, and resource-compensating learning environments that mitigate insecurity-related trauma, enhance engagement, strengthen conceptual understanding, and foster practical skills. Locally generated empirical evidence from a quasi-experimental study in Sokoto State confirms significant academic performance gains (mean gain of 33.4 points), measurable increases in student engagement (from 3.5 to 4.6 out of 5), and a statistically significant improvement in interest in practical skills (mean difference = 17.7; p < .05) among VR-instructed learners (Danmali et al., 2024). The paper delineates the contextual imperatives, pedagogical foundations, ethical considerations, and practical implementation frameworks necessary for large-scale XR adoption in Northern Nigerian schools, providing a policy-relevant pathway towards resilient, equitable, and future-ready STEM education
