Intercultural telecollaboration allows for a radical change in language education. New technologies enable learners of different languages and cultures to practice their intercultural skills. Teachers no longer need to design "fake" role-plays to develop interaction in the target language. Above all, teachers have the possibility to address the cultural and intercultural dimensions of language education. This paper presents the multifaceted dimensions of a telecollaboration project in English as a Lingua Franca (ELF) with university students in science from UPMC, Sorbonne-Universities, Paris and university students in education from University of Valladolid, opening further questions on the exploration of intercultural telecollaboration in higher education.
