This chapter explores virtual exchange (VE) as a site of disciplinary praxis through a collaborative project involving preservice English for Specific Purposes (ESP) teachers in Argentina and university students in Greece studying English for Intercultural Communication. Grounded in scenario-based learning within the tourism and hospitality fields, the project engaged participants in co-constructing and analyzing intercultural incidents using De Bono’s Six Thinking Hats and the 3Ps framework (products, practices, and perspectives). The VE created an authentic, digitally mediated space for applied disciplinary learning in which Argentine preservice teachers developed professional language use, pedagogical design practices, and intercultural awareness, while Greek students applied theoretical concepts to culturally situated communicative challenges and proposed context-sensitive responses. Through collaborative tasks, multimodal communication, and structured reflection on critical incidents, participants engaged with discipline-specific problems and interpreted culturally shaped behaviors. These activities corresponded to areas in which participants reported heightened intercultural awareness, confidence in communication, and perceived professional readiness. Post-project survey-based reflections further suggest that VE supported students in approaching intercultural misunderstandings with greater critical awareness, adaptability, and self-awareness. Taken together, the chapter illustrates the potential of VE to integrate disciplinary practice, language, and culture and to support professional learning through transnational, digitally mediated collaboration in tourism and hospitality-related contexts.
