Abstract
This paper reports on Intermediate "Interaction" classes started from 2015 following a reorganization of the Japanese language curriculum at Hokkaido University. The new curriculum, which consists of three modes: "Interaction" "Expression" and "Comprehension", aims at enabling international students to participate equally with Japanese students in problem-solving and project-based classes. This report introduces class design and activities implemented in Intermediate "Interaction (Basic)" and "Interaction (Practical)" classes in 2015 to achieve goals, skills, and outcomes set for each of these three levels. Some problems and issues that require improvement and further consideration are also discussed.
