This article grapples with my endeavour to guide teacher education students to think critically about environmental issues and action. While students repeatedly claim my efforts helped them to think critically, my interviews with them about environmental issues and practices cause me to doubt their claims of burgeoning critical engagement. This article demonstrates the fraught nature of critical pedagogy and my inability to create a climate in which guidance in the field of Outdoor and Environmental Education might come to be doubted. Drawing from a larger longitudinal study of the formation of environmental ethics among tertiary Outdoor and Environmental Education students, in this article I examine the experience of one student to critique my pedagogical practice and also to consider how this has provoked a revision of my own approach to teaching in this field. In the final section, I highlight the importance in teacher education more broadly of providing space for guidance to be doubted and opportunity for students to self-stylise and create their own responses to current issues.
