I am preparing a draft article examining the challenges of teaching international relations (IR) to Japanese undergraduate students in English. Japanese students introduced to the social sciences, particularly IR, face a number of unique challenges: an academic discipline almost entirely developed from a Western perspective; understanding terminology, concepts, and theories in English; and socio-cultural barriers in the classroom that hinder student participation. The strategies employed by the author may also be of interest to English-language instructors of other social science disciplines.
