Abstract
This study analyzes the dynamic process of how 3-year-old children learn the 'good-bye' greeting routine during the daily good-bye assembly at kindergarten. The analysis is based on the observation and detailed record of interaction between the teacher and the children as well as interaction among the children. The results show that children initially sought their own pleasure and did not follow the routine, however, overtime as they became fond of "acting together" with peers, they followed the routine. Teachers encouraged children to follow the routine by reducing time between routine elements. Then gradually, children started to encourage each other to follow the routine. It is considered that in order for children to spontaneously learn the routine, it is important for them to influence each other, while teacher-child attachment is necessary as a basic foundation.
