Ethics: Collaboration (human or AI)
All work, not done by the student must be cited. We cite authors, we should cite co-authors and collaborators. The writing process with an AI is a collaboration between two creative entities. The student gives shape with prompt engineering and hopes for good results. The AI is responsible for content creation, it "deserves" to be cited. Not so much "deserves" because it, like a human, labored, but "deserves" because all laborers on a project must be acknowledged and held accountable for the work submitted. So, in any collaborative assignment, the work of each individual (human or AI) needs to be identifiable (either explicit, in an another document, or in notes within the document).
The writing produced by the AI can be edited by the human author, but again, the AI "wrote" and contributed to the paper. The AI is another creative entity. So, any work turned in, that includes AI material is a work that was co-authored. The AI was the co-laborer; the collaborator.
One of our main issues with AI is that the final project is not entirely the work of the student. The grade earned, received, should be based upon the work of the student. It is imperative that the work of the AI be identified. The student should be held responsible for all the work turned in.
