Taitung Xinsheng Elementary School's cross-disciplinary aesthetic course was held at pop-up performances in schools and urban areas on April 24. It is the first case of cross-disciplinary courses. The children in the art class visited nearby aboriginal tribes and were inspired by their music. The whole class worked together in groups to compose music and made some of their own instruments. Finally, the jointly created music was used as an opening pop-up performance for their graduation art exhibition. ! !
