This document discusses the #CulturaTándem project, which pairs students from different cultural backgrounds and locations for online research collaboration. The project aims to develop students' linguistic skills, intercultural competence, and digital and professional skills. Students work in cross-cultural "tandems" to research topics like ecotourism, indigenous peoples, and marketing. Survey results found that students improved research skills by investigating topics scientifically with a partner, exchanging information regularly in a foreign language, and incorporating different cultural perspectives. Working with an unknown partner from another culture and location helped students learn to accept different opinions, find common ground beyond borders, and appreciate openness to new ideas.
