Mezirow's (1978) transformative learning was influenced by Kuhn's (1962) paradigm and Freire's (1970) emancipatory learning. In this paper, the author provides readers a clear guide about the main components of transformative learning: Experience, critical reflection, and rational discourse. The author emphasizes that experience in transformative learning is not the ordinary, daily mundane experience, or the new experience added on top of our old experiences, but that experience which fundamentally conflicts with what our assumptions can explain. Transformative learning is to challenge or disturb the fixed assumptions. Through critical reflection, learners examine the origins of beliefs in their historical and biological context and take actions to change their pre-existing assumptions to better understand the current disoriented experience. Finally, the author provides recommendations about how to apply transformative learning in practice.
