The present study explores the nuanced effects of metaverse-based spatial computing environments on the development of intercultural communicative competence among undergraduate students acquiring Mandarin as a foreign language within digital university programs. While the existing body of applied linguistics literature has broadly recognized the importance of cultural immersion for language acquisition, there is a notable scarcity of empirical research examining how metaverse-based spatial computing specifically interacts with learner outcomes in highly structured, avatar-mediated educational contexts. To bridge this theoretical and practical gap, the researchers designed a comprehensive, longitudinal mixed-methods study. Quantitative metrics were gathered using standardized language proficiency batteries and cross-cultural adaptability inventories, while qualitative dimensions were captured through extensive in-world ethnographic observations, reflective learner journals, and semi-structured focus group discussions. The study engaged a total cohort of 150 participants, systematically divided into an experimental group (n=75) and a control group (n=75), over the course of a full 24-week academic term. The experimental cohort was exposed to an intensive curriculum centered around synchronous, multi-user metaverse simulations representing target-language cities, whereas the control group adhered to a conventional 2D video-conferencing pedagogical approach. Comprehensive statistical analysis, incorporating multivariate analysis of variance (MANOVA) and repeated-measures t-tests, demonstrated a statistically significant enhancement in the experimental group’s intercultural communicative competence (p < .01). Furthermore, the qualitative data analysis revealed that learners in the experimental setting exhibited heightened intrinsic motivation, a marked decrease in foreign language speaking anxiety, and a stronger sense of learner autonomy when navigating virtual societal norms. These compelling results strongly advocate for the systematic integration of metaverse platforms into modern language curricula. The paper concludes by outlining actionable pedagogical frameworks for educators, discussing potential limitations of the current study regarding hardware access inequality, and suggesting vital trajectories for future research across distinct linguistic and cultural backgrounds.
