The purpose of the study is to reveal what changes in self-awareness are expressed in the process of expressing various situations in art in the experience of interaction with others. Therefore, in this study, in order to analyze the meaning of art as a self-understanding by implementing multicultural art education, a self-recognition art program was designed centering on self-portrait art activities, and art activities and in-depth interviews were conducted with one male teenager attending a Christian alternative school. The collected data were categorized, analyzed, and interpreted through coding work.
