Abstract: This report presents selected aspects of an inquiry based on a conversation with Raeleen, a graduate of a post-graduate nursing programme. Raeleen talks about her experience of critical thinking during her post-graduate studies. The authors suggest that, through this conversation, it is possible to explore the nature of critical thinking and examine the important roles teachers can play in facilitating its development. Includes discussion questions prepared by Rebecca Hennephof that consider the relevance and impact of critical thinking on nursing practice.
