This paper reports on a short-term exchange program in a science university. The participants are undergraduate engineering students from Singapore. The purpose of the program is for them to gain insight into research activities while familiarizing themselves with the system and practice of research laboratories at a Japanese graduate school. The program provided the participants with the opportunities to be engaged in collaborative learning and mutual exchange with Japanese students and scholars in the plurilingual environment as they achieved their presentation tasks together. The participants gain not only the knowledge in their related fields, but also the Japanese language communication skills through the process.
