Investigating the roles of first language (L1) speakers in lingua franca communication in multicultural classrooms: a case study of Japanese as a Lingua Franca (JLF)

Abstract

Abstract In the Expanding Circle (i.e. countries where English is traditionally learned as a “foreign language”), the concept lingua franca cannot be limited to English. Conducted in a Japanese university, this study reports on the perceptions of verbal behaviours by students in multicultural courses where international and Japanese students studied together. These behaviours were analysed and the findings from English medium instruction courses and those of Japanese-medium instruction (JMI) courses were compared. Then, further analysis centred on JMI courses to explore the roles of Japanese L1 speakers in the co-construction of Japanese as a lingua franca with a focus on cognitive and psychological, rather than linguistic, perspectives. Rapport building, accommodation strategies, often initiated by L1 Japanese speakers, and the spontaneous interactions of second language (L2) speakers in discussions, are assumed to have been the keys to more inclusive interactions in JMI courses. The findings emphasize the importance of students’ attitudes and imply that intercultural education in the context, including both L1 speakers and L2 speakers, will have potential to foster effective lingua franca users.
