Using the framework of conversation analysis, this paper examines the communication problems which international graduate students in engineering encounter when they have a Q&A session in Japanese after giving a presentation. This analysis focuses on (1) the phenomenon where international students fail to initiate a ‘repair sequence’ (Schegloff et al. 1977) to attain mutual understanding among participants when they do not understand a question from the floor ; and (2) why the conversational procedure of ‘repair’ is not employed by these students. Finally, this paper discusses what kinds of classroom activities can be introduced to solve these students’ communication problems. These issues are also applicable to situations in which native speakers of Japanese use English or other foreign languages in engineering communities.
