This chapter examines the relevance of transformative learning theory as it applies to online graduate courses. It is argued that the nature of learning that occurs in such courses involves a high degree of reflection and critical analysis and hence is well described by transformative theory. Discussion forum postings from 3 different courses at different institutions are analyzed in terms of the meaning structures defined by Mezirow. The results support the assertion that meaning schema and perspectives are being created and changed as a consequence of interaction with peers and instructors during online classes. A number of suggestions for refining the study of transformative learning in online courses are provided.
