Kyushu University has conducted a two-week immersion program for Thai college students. This program is designed to provide the students with various opportunities to experience Japanese culture from their own viewpoints. As part of the program, the Japanese language classes supported experiential activity by equipping students to plan and carry out activities on their own initiative. This paper reports on a group activity in which students conducted a field trip and made follow-up group presentations. Results show that the course support which made use of students' interest and interaction enabled their trips and the presentations reflecting their own points of view.
