IntlUni: The challenges of the multilingual and multicultural learning space in the international university The past decade has witnessed an unprecedented increase in the internationalisation of higher education. This means that more people in higher education than ever before are teaching and learning through the medium of a language other than their own first languages. What are the implication of this for lecturers and students? And what are the implications for this for the quality of European higher education programmes? Taking it for granted that the internationalisation of higher education adds value – or has the potential to add value – to the programmes offered and the learning outcomes achieved by students, the overarching aim of IntlUni is to identify the quality criteria that characterize or should characterize teaching and learning in the multilingual and multicultural learning space, and to develop recommendations for how higher education institutions may implement and ensure the sustainability of quality teaching and learning in this space. IntlUni is a three-year Erasmus Academic Network (2012-2015) and has received financial support from the European Commission’s Lifelong Learning Programme. This paper will spell put the concrete aims and objectives of the Work Packages of the project, outline the first results of a Europe-wide survey conducted in January-February 2013, and discuss the implication of these as well as the next steps for action. IntlUni has 38 higher education partners in 28 European Countries.
