In this study, based on the actual situation and issues of the children in the 6th grade, we decided to launch an art department and work on a musical for the whole grade. We developed a unit based on the idea of Project Based Learning. In this project, we divided our efforts into six phases to help children recognize others and achieve self-actualization. By experiencing the process of working with various others, the children were able to demonstrate their strengths and realize the value of working with others.
