This study employs a mixed-methods design to assess the integration of GeoGuessr and problem-based learning (PBL) in enhancing cross-cultural communication skills and cultural sensitivity among English as a foreign language (EFL) learners in a Chinese context. The quantitative phase, utilizing pre- and post-test measurements with Likert scales, shows significant improvements in the cross-cultural communication skills and cultural sensitivity of the experimental group engaged with GeoGuessr and PBL compared to a control group. The qualitative component, involving systematic observations and semi-structured interviews, highlights differences in instructional environments, student interaction, cultural communication skills, sensitivity, and pedagogical strategies between groups and reveals themes related to increased cultural awareness, critical thinking, collaborative learning, and academic engagement. The findings endorse the potential efficacy of GeoGuessr and PBL in EFL settings, enriching EFL pedagogy and suggesting further research pathways.
