The course tends to strengthen students' knowledge of conceptual and methodological issues related to the investigation of language in its broadest sense. It also intends to give them a greater awareness of the critical national and international interactive issues, connected with the language contact considered in the broadest sense, together with additional adequate communication tools in the languages of reference, whose nature includes multimedia, training them to use the most effective and appropriate vehicle language within multicultural and multiethnic environments and in the most different psycho-socio-cultural and socio-professional contexts.
