In an increasingly globalized world, the development of language skills and intercultural empathy has become crucial for effective communication and collaboration across diverse societies. Virtual worlds offer a unique and immersive environment to address these needs through innovative educational approaches. This study explores the impact of multi-user interactions, group work, and simulations within virtual worlds on language learning and the development of intergroup empathy. Two distinct research projects were conducted, involving 241 participants aged 19–45. The language learning study engaged 116 participants in diverse interactive experiences, while the intercultural study had 125 participants collaborating in multicultural groups and participating in perspective-taking simulations. Both studies employed qualitative data collection methods, including surveys, interviews, and observations. The findings suggest that the combination of networking strategies, collaborative learning, and simulations within virtual worlds contributes to improvements in learners’ language proficiency, confidence, and empathy towards diverse social groups. Participants reported increased motivation and engagement, which was attributed to the immersive and interactive nature of the virtual environments. These studies highlight the importance of collaboration and reflection in facilitating language acquisition and intercultural understanding. Technical challenges were identified as potential barriers to implementation. The results demonstrate the potential of virtual worlds to enhance language education and foster empathy in diverse societies, offering valuable insights for educators and researchers. However, the findings may be limited by the specific contexts and sample sizes of these studies, warranting further research to explore the generalizability and long-term impact of virtual world interventions and not exaggerate the main conclusions.
