This thesis aims to explore the possibility of self-transformation through the process of actor-teachers practicing to connect theater and life, by a case study of the community of actor-teachers in the Taipei City Embankment Elementary School. Based on the viewpoint of Moreno’s Theory of Roles, this thesis discusses how actor-teachers take roles, play roles and create roles to extend the self-role catalogue by operating the three stages actively: real life, drama and the interactive site of TIE. The findings of this thesis are as follows: 1. Role-playing can promote the self-understanding and the self-development of actor/teachers. 2. Role-shifting can clarify self-values of actor/teachers. By participating TIE, the self perceives the self-life problems actively, which means that the self takes up the responsibility of the ‘protagonist’ of the self-life script, thus setting out on a transformation journey at the same time.
