Significant learning produces lasting, transformative changes in how individuals think, act, and view themselves (Fink, 2013). We developed a Learn-Change-Grow critical reflection strategy based on Borton's (1970) What? So What? Now What? model. This strategy guided doctoral students (N = 32) through weekly critical reflections of their genAI use for the semester-long authentic course project and for their genAI use in academic and workplace environments. Qualitative analysis of over 100,000 words of student reflections showed evidence of growth across all six categories of significant learning. This session shares the reflection strategy and implementation guidance attendees can adapt for their own teaching. #critical-reflection #significant-learning
