While most drama-in-education activities include the students in the dramatic process, the teachers are often excluded. This exclusion creates a gulf between the fictional world inhabited by the students and the real world of the teacher, making it difficult for the teachers to scaffold and challenge the students without undermining the fictional world. One exception to this phenomenon is Teacher-in-Role. This article will analyze the process drama technique called Teacher-in-Role and discuss its functions, types, benefits, potential challenges, and solutions to avoid or manage these challenges. This article also includes examples of Teacher-in-Role to provide the readers with a better understanding of how this process drama technique can be used.
