In this chapter, we ask how drama and theatre can be a useful approach to action research processes. We focus on interventions, using teacher education as an arena for development. The empirical point of view is based on several research and developmental projects over years, together with two examples from recent developmental work. Our theoretical framework is based on theories of learning and transformation, as well as various perspectives on action research. The connection and similarities between drama and theatre and action research, will also be discussed in this chapter.
