Traditional ecological knowledge is a potentially powerful medium in which to teach environmental education and has the potential for influencing transformative learning. Although many educators agree that one of the focuses of environmental education is adult transformation, this has not been extensively explored in the context of Hawaiian environmental knowledge. Specifically, there has been very little work done in immersion courses where nonnative and part-native students learn from local and indigenous experts. The purpose of this study is to explore the possibility of transformative learning in this context. This article investigates student responses to the course curriculum and instructional methodologies of an undergraduate, introductory immersion course on Hawaiian environmental knowledge. The article also explores one student's transformation through her participation in the course and describes the conditions that were met to catalyze that transformation.
