This Open Studio shares an in-progress Feminist AI–informed learning design framework that examines how power, authorship, and agency shift when Generative AI is introduced into secondary education. Drawing on classroom pilots, design research, and assessment tools such as a Student-Author Voice rubric, the work explores how LLMs can be integrated through co-creation and gradual immersion, rather than extraction or automation. The session foregrounds methodological tensions, ethical trade-offs, and policy-relevant questions emerging from real educational contexts.
