Teaching students to check what AI tells them

Of everything schools might teach about AI, one habit outlasts the rest: checking. Here is a way to teach it that takes a single lesson and actually sticks.

Most AI guidance for schools is about restriction. Restriction is necessary and it ages badly — the tools change, the rules chase them. One thing does not age: a student who checks before relying on an answer is protected from every model, including ones that do not exist yet.

Why students do not check on their own

Not laziness. Fluency reads as competence. A model's wrong answer arrives in the same measured, confident register as its right one, with no hedging and no visible seams. Every social cue we use to gauge reliability in a human — hesitation, qualification, admitted ignorance — is absent.

Students are not being careless when they trust it. They are applying a heuristic that works on people to something the heuristic was never built for. Say that out loud to them; it lands better than being told to be sceptical.

The lesson that works

Ask the class a question in your subject where you know the model produces something plausible and wrong. Specific dates, obscure attributions, precise statistics and citations are reliable places to look. Project the answer.

Then have them verify it against a real source, and find the error themselves. The moment a student catches a confident machine being wrong is worth more than any amount of instruction about limitations, because they now have a memory rather than a rule.

Run it once a term with a fresh example. It stays true as the models improve, because the failure mode is not going away — it is getting subtler, which makes the habit more valuable, not less.

A rule students can actually remember

Long lists of guidance do not survive contact with a deadline. One sentence does:

If it matters, check it somewhere else before you use it.

"If it matters" is doing deliberate work. Nobody verifies a brainstorm or a rephrasing, and demanding that guarantees the rule gets ignored entirely. Facts, figures, quotations, citations and anything going into submitted work — those matter.

Watch for invented sources

Worth teaching specifically, because it surprises people. Models generate citations that look correct in every respect — plausible author, plausible title, plausible year, plausible journal — and simply do not exist. The format is learned; the reference is not retrieved.

The rule follows directly: a citation you have not opened is not a citation. If a student cannot produce the source, it does not go in the work.

Make disclosure safe

If admitting AI use is punished, students conceal it, and you lose the visibility that would let you teach anything. Ask for one line — which tool, for which part, what they changed — and treat an honest line as compliance rather than as a confession.

The students you most want to reach are the ones who would otherwise never mention it.

Navōn gives schools a filtered tool to teach this with, rather than one to police.

Common questions

Why does AI make things up?

A language model predicts plausible continuations rather than retrieving facts. A fabricated citation is generated in the correct format because the format was learned, even though the reference was never looked up.

How do I teach students to spot AI errors?

Ask a question in your subject where the model produces something plausible and wrong, project the answer, and have students find the error against a real source. Catching a confident machine being wrong teaches more than instruction about limitations.

Should students be allowed to cite AI as a source?

No. It is not a source; it does not retrieve, it generates. Students should verify claims against real sources and cite those, and a citation they have not opened should not go into the work.
