In tertiary education, the alarm greeting the new ubiquity of Large Language Models like ChatGPT and DeepSeek has been driven largely by concerns about Generative AI’s impact on academic integrity. Especially, humanities educators have asked what the impact of LLMs will be on students’ willingness to adhere to previous standards of originality in written work. What we as educators miss when we ask this question about our students is the opportunity to ask another question with them: how can GenAI tools clarify our preconceptions about what “originality” means in the first place? Building from a qualitative study of student co-creation with GenAI, this workshop explores ways that using GenAI tools in humanities classrooms not only can hone our ideas of what it means to claim original authorship when we write in community with other writers and thinkers, but also can foster critical thinking skills, responsible AI usage, and student agency in the classroom.
