English as a Lingua Franca (ELF) is the use of English among speakers of different first languages for whom English is the communicative medium of choice, and often the only option (Seidlhofer, 2011). Our Japanese students have the opportunity to use ELF with teachers and tutors who have different first languages. As many students may go on to work in multicultural and multilingual situations, our goal is to raise student language awareness of ELF contexts. This study, which is part of a larger research project on ELF-oriented curriculum development, focuses on student assessments of listening and speaking using insights from the literature on ELF and project-based learning (PBL).
