In my Japanology course in the Spring semester, I try as much as possible to use only English throughout the whole course. That is all my lectures and answers to the students' questions are in English, all my handouts are in English, all the reading materials are in English, all email correspondence with the students is in English, and all the assignments and exams (and my feedback comments) are in English. The purpose of this style of teaching is to implement fully the ELF philosophy of using English as a shared language to learn and discuss academic content. The model is to try and bring the class time as close as possible to a study-abroad type of experience for the Tamagawa students.
