One of purposes of general education is to educate children and make them creative. Recently, it seems that the importance of creativity is more emphasized in general education. Under this circumstance, the theme of creativity is sweeping through the field of art education. That is to say, now it is considered that this theme, creativity, is essentially central to the field of art education. Many people in and even out of the field of art education believe that art would be an effective subject to develop children’s creativity. Therefore, developing effective art lessons for children’s creativity has been an important issue in art education. However, although we have paid great attention to creative children, we have not considered who could be a creative art teacher who prepare creative art lesson for children. In order to help children develop their creativity, we must think how art teachers can be creative and how they can prepare creative art lessons effectively. Art teachers has been understood as an artist teacher. It means that they have dual identities such as an artist and a teacher. Many teachers, ironically, try to be a good artist in order to be a professional and creative art teacher. However, they should be professional and creative in both areas. How can they develop their dual identities effectively. This study introduced 8 student art teachers’ creative classroom research using an art-based research method and explained how this project was initiated, what was the process of the project and what participants learned from it. Through participating in this project, student art teachers learned how to incorporate their interest in art-making into their classroom research and it was identified that they became more competent in conducting research. The result of this study shows if the discourse on the possibilities of art practice as research among only scholars is introduced to practitioners, art teachers, it would be helpful for art teachers prepare more effective art lesson for their children’s creativity.
