Ask a classroom "who wrote which sentence" and you have already taught the lesson. The AI-authorship fence is the small piece of language that makes the answer routine, not awkward.
What the fence is
The fence is a short, standing disclosure that travels with any classroom artifact where an assistant helped draft, summarize, reformat, translate, or check work. It names the human author, names the assistance, and names what the human did with the output. It is not a confession. It is a fact, printed next to other facts.
The fence lives on: student essays, teacher handouts, slide decks, exam study guides, lab writeups, and anything a school publishes on a public site. If a page carries an argument, it carries a fence (Class C, since the disclosure is a configuration choice on the artifact itself, not a behavior we hope for).
Why a fence and not a ban
Bans do not survive contact with a phone in a backpack. A fence does, because it costs the honest student nothing and costs the dishonest student a specific, nameable thing: a false line about authorship. The pedagogical bet is that legibility beats prohibition. Once students see the fence often enough, they start writing their own without prompting, which is the point.
There is a wider frame too. In active-inference terms, the classroom is a shared generative model of "who knows what, and how." An undisclosed assistant is an unmodeled cause: it makes the whole model wrong in ways nobody can inspect. The fence closes that gap (Class E, in the sense used by Parr, Pezzulo, and Friston, 2022, where hidden causes distort inference across the system).
When the fence applies
The rule of thumb: if an assistant touched the artifact in a way that changed what a reader would attribute to the student, the fence applies. Concretely:
- Drafting or rewriting sentences: fence.
- Summarizing a source the student did not read in full: fence, plus a citation to the source.
- Generating a diagram or table from student notes: fence, and keep the notes.
- Translating: fence, with the source language named.
- Reformatting (bulletizing, tightening headings, fixing markdown): fence, one line, no drama.
- Spellcheck and grammar underlining a native word processor already does: no fence needed. The floor is the ordinary word processor.
The rule is not about tool sophistication. It is about attribution. If a reader would be surprised to learn an assistant helped, the fence is required.
A copy-ready fence block
Teachers can lift this verbatim or adapt the phrasing to a house style. It is deliberately calm and short.
AI-Authorship Fence
Author (human): [Student name]
Assistance used: [Name of assistant, e.g. "a general-purpose writing assistant"]
Role of assistance: [drafting / summarizing / reformatting / translating / checking]
What the human did with the output: [reviewed, edited, kept X paragraphs verbatim,
rewrote Y paragraphs, discarded Z paragraphs]
Sources cited above are the human's, not the assistant's.
For a class publication or a public site, add one more line: "This artifact is not a claim about the assistant's abilities. It is a record of how this piece was made."
That last line is doing real work. It stops the disclosure from turning into a marketing endorsement of whatever tool the student happened to use.
The three habits the fence teaches
The fence is a piece of paper. The point is the habits it forms.
- Naming your sources of help. Not just books and websites, but also people, teachers, tutors, and assistants. The student learns that "help" is a category with subtypes, and each subtype gets named.
- Distinguishing "reviewed" from "wrote." A student who fences honestly starts noticing when they have signed off on a sentence they did not actually think through. That noticing is the beginning of editing as a real skill.
- Publishing with receipts. The fence is a small receipt. Once students carry it, other receipts (citations, dates, versions) feel less foreign. This is a curricular ramp into the wider honesty posture we ask of every artifact on this site.
The teacher's version
Teachers publish too. Handouts, syllabus updates, parent letters, and public blog posts all belong under the same fence. Modeling it is the fastest way to normalize it. A syllabus that fences its own composition history teaches more, in one line, than a semester of exhortations about integrity.
Where to go from here
- Read the Transparency page for the evidence-class rubric and the exact house language.
- The cluster overview is at honesty-in-classrooms-the-ai-authorship-fence, which sets the wider context and links the family of posts.
- Grab the classroom-ready form at student-declarations-a-template and adapt it to your grade band.
- If you want the fence explained in a live setting with real student examples, book the Workshop and bring a colleague. It travels better in twos.
