Abstract
In a Japanese language class for international students, I teach a play in the Kobe dialect with the help of Japanese students. To enhance leaning effect and create a play with higher quality, it is essential for all students to actively take part in all the process. In order to sustain the motivation of all the students for the whole semester, I made each student set individual objectives (assessment points) beforehand, assess them with each other among all the students after the performance day, and the average scores were integrated into part of their grades in the 2011 fall semester.
