    PhD dissertation project

    Using a corpus of international video-mediated communication to improve intercultural and communicative competence in English as a foreign language (EFL) teaching 

    (Einsatz eines Korpus von internationaler videobasierter Kommunikation zur Förderung interkultureller und kommunikativer Kompetenz im fremdsprachlichen Unterricht)

    Doctoral grant: Konrad-Adenauer-Stiftung (KAS)

    Abstract: My dissertation project focuses on features of transatlantic communication –  in this case a corpus of Skype conversations between native speakers of English (students from the UK and the US) and non-native speakers of English (German students), which is part of the CASE (Corpus of Academic Spoken English) project.  The transatlantic corpus will allow research in various fields such as linguistics, EFL (English as a foreign language) teaching and cultural studies. Frequently used linguistic features will be detected and their use among native and non-native speakers will be analyzed in greater detail. The results will provide implications for language teaching as to how frequently used features should be tought and in how far they complement to authentic language use. Different cultural aspects can be found in conversations about food, traditions and TV shows. Their impact on intercultural communication and mutual understanding will also be subject to analysis.
