The emerging subjects and policy which relate to the curriculum reforms have been promoted and implemented constantly in Taiwan. This research focuses on how teachers’ experiences are shaped during the promotion of school-based curriculum development. I am deeply inspired by Foucault’s viewpoint of power, which leads me to the concern about the subject of the school teachers. To collect the more detailed and tiny teachers’ experiences, I took advantage of Narrative Interview as well as Spot Inspection. Moreover, I interpreted the collected material with Foucault’s theory. Finally, some suggestions were proposed to contribute to the promotion of the curriculum reforms.
