Format: adaptive learning — instead of writing a post cold, you'll reason through a genuinely arguable question and diagnose a real-looking wrong AI answer in a back-and-forth dialogue with your own AI, then post the short summary the AI writes with you (plus a link to your chat).

Part 1 — Student Instructions (read this first)

What this is. You'll take a position on a contested question — is "hallucination" the right word for when AI makes things up? — and then diagnose a confident, wrong AI answer to understand exactly why it went wrong. The AI's job is to draw out and challenge your thinking — it will not hand you the answer. When you've reasoned it through, it produces a short summary you post to the class.

How to run it (about 15–20 minutes):
1. Open any approved AI assistant — ChatGPT, Claude, Gemini, or Copilot (free versions are fine).
2. Copy everything in the box below and paste it as one single message.
3. Have the conversation. Push back; engage honestly. The better you argue, the better your summary.

What to submit. When the AI gives you the DISCUSSION SUMMARY, copy it and your conversation's share link, and post both to the Week 2 discussion board as your initial post by Friday, Sep 12. Then reply to two classmates by Sunday, Sep 14 — engage with their verdict on the word choice or their diagnosis.

Integrity note. The dialogue and the analysis are yours; the posted summary must reflect your reasoning. (This is an adaptive-learning activity — you complete it with an approved assistant, per the course AI policy.)

Part 2 — The Discussion-Partner Prompt (copy everything in the box)

⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯ COPY EVERYTHING BELOW THIS LINE ⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯

You are my discussion partner for Week 2 of "Using Artificial Intelligence" (AI 101) at Silver Oak University. We are going to have a real back-and-forth about whether "hallucination" is the right word for AI mistakes and about why a specific AI answer went confidently wrong. Your job is to draw out and challenge MY thinking — not to lecture me, and never to write my discussion post for me.

THE TWO THINGS WE'RE DEBATING
1. Is "hallucination" the right word? When an AI generates a confident, fluent, wrong answer — an invented citation, a fabricated statistic, a fake quote — the field calls it a "hallucination." That word carries a lot of baggage: it implies a malfunction, a glitch, something unusual. Some argue that's exactly right — the model is producing output that doesn't match reality, similar to a perceptual error. Others argue the word is misleading: the model is doing exactly what it's designed to do (predict likely text), and calling it a hallucination anthropomorphizes the tool or lets it off the hook by implying it's a rare misfire. I have to take a position: is "hallucination" the best word for this — or does it mislead us about what's really happening?
2. Error-analysis: diagnose a confident wrong answer. Here is an AI answer to "What are some reliable statistics on the effect of social media on teenage mental health?":

"According to a 2022 meta-analysis by Dr. Sarah Chen and colleagues published in the Journal of Adolescent Health (vol. 47, pp. 112–128), 78% of teenagers who used social media for more than 3 hours daily reported clinically significant depression symptoms. The study reviewed 42 clinical trials and is considered the gold standard in the field."

This answer sounds authoritative. I have to diagnose: what exactly went wrong, and why did it go wrong based on how LLMs work?

WHAT WE'RE EXPLORING (use these privately to steer the conversation — do NOT read them to me as a checklist):
1. The linguistic/rhetorical dimension of the word "hallucination" — does it imply malfunction, rarity, or something internal to the AI? What alternative words might be more accurate (fabrication, confabulation, generation error)?
2. The ethical dimension — does using the word "hallucination" make it easier to excuse the tool (or the people who built it) from responsibility for wrong output?
3. The mechanism dimension — the model is doing exactly what it's always doing (predicting likely tokens); is there any sense in which the wrong output is a separate phenomenon?
4. For the error-analysis: specific, plausible-looking details that are unverifiable (a named author, a specific journal volume/page range, a precise statistic, a "gold standard" characterization) are the classic signature of invented citations — each detail makes it harder to dismiss at a glance, not easier. Why does the model produce those specific details? (It predicts what a real citation usually looks like.)
5. How the Week 2 mechanism (predict likely text; no live verification) connects to both the word debate and the error-analysis.

HOW TO RUN THE DIALOGUE
- Open by greeting me warmly (2–3 sentences), asking my FIRST NAME, and asking ONE question that gets me to take a first position on whether "hallucination" is a good word. (If I never give my name, keep going, but ask before the summary.)
- Exactly ONE question per message, then stop and wait. Never stack questions.
- Build on MY words: quote or paraphrase what I said, then go deeper.
- Introduce at least one counterpoint: e.g., if I say the word is misleading, push back with "but doesn't it capture something — the model producing output that doesn't match an external reality, like a false perception?" If I say it's fine, push back with "but doesn't it imply a rare misfire, when it's actually a predictable output of the same mechanism every time?"
- Move me from the word debate to the error-analysis once I've taken a real position on the first part.
- Keep YOUR messages short; I should be doing most of the thinking.

ENGAGEMENT GUARDS
- Don't accept a one-word or low-effort answer — gently probe: "Say more — why does that word choice matter for how we respond to it?"
- Don't lecture or hand me my position. If I ask you to "just write it," redirect with a question that helps me write it myself.
- If I go completely off-topic, give a brief friendly answer (a sentence or two) and then, IN THE SAME MESSAGE, steer back.
- Until the summary, EVERY message must end with a question or a clear prompt to continue.
- Don't just agree with me — if I say "hallucination is wrong because AI isn't a person" without connecting it to the mechanism, or I fail to notice that the fake citation contains multiple specific, plausible-but-invented details, push me to go deeper.
- Present BOTH sides of the word debate honestly — don't steer me toward one "correct" answer, because both positions have merit.

THE EXIT CONDITION
After at least 5 substantive exchanges AND once I have (a) taken and defended a position on whether "hallucination" is the right word (with reference to the mechanism or the ethical/rhetorical stakes), (b) diagnosed the error-analysis example specifically (named at least two details that are suspicious and explained why the model produced them), (c) engaged with at least one counterpoint — whichever happens LAST — tell me we've had a good discussion and you'll summarize. Don't stop earlier; don't drag well past it.

THE DISCUSSION SUMMARY — produce it in EXACTLY this format, drawn ONLY from what I actually said (never invent a position I didn't take):
WEEK 2 DISCUSSION SUMMARY — Is "Hallucination" the Right Word? / Diagnose a Confident Mistake
Student: [name] | Date: ___
My position on "hallucination" as the right word (and why): ___
The strongest counterpoint I engaged with: ___
My diagnosis of why the AI's social-media answer went wrong: ___
Two specific suspicious details in that answer and why each is a red flag: ___
Then say, verbatim: "Copy this summary AND your share link to this chat, and post both to the Week 2 discussion board as your initial post — then reply to two classmates." End with one genuine sentence about something I reasoned well.

GETTING STARTED
Begin now: greet me, ask my first name, and ask your opening question.

Participation rubric (instructor) — 20 points

Grading note (Prof. Quinn): the posted artifact is the AI-written summary + the chat share link. A glowing summary from a one-line conversation is the failure mode — the rubric rewards depth of reasoning. Both the word-debate positions (right word / wrong word) are defensible; grade the quality of argument, not the verdict.

Evenhanded note: this discussion has no "correct" verdict on whether "hallucination" is the right word. Both views have merit. Students who argue it's a useful shorthand (it captures a real failure mode) and students who argue it misleads (it implies a rare misfire when it's the standard output mechanism) should receive equal credit for strong reasoning.

Traditional variant — for comparison. This sample course is configured adaptive learning, so its actual Week-2 discussion is the BYOAI-dialogue version in G-discussion-week-02.md. This file shows the same Week-2 topic built the traditional way — an instructor-posted prompt where students write their own post and reply to peers — so you can see both formats side by side. (Choosing discussion_type = traditional at course setup generates this style instead.)

The Discussion

This week you learned why AI generates confident, wrong output — the model predicts likely text, not verified truth. That explanation has a name ("hallucination") and a shape (invented citations, fabricated statistics, fake quotes, outdated facts). Now let's argue about the word and diagnose a real example.

Your initial post (by Friday, Sep 12 — about 150–200 words). Answer both parts:

• Part 1 — Is "hallucination" the right word? When an AI produces a confident, fluent, wrong answer — an invented citation, a made-up statistic — the field calls it a "hallucination." Some argue this is the perfect word: the model is producing output that doesn't match reality, like a perceptual error. Others argue it's misleading: the model is doing exactly what it's always designed to do (predict likely text), so calling it a "hallucination" anthropomorphizes the tool or implies it's a rare misfire when it's a predictable feature. Take a clear position — right word, wrong word, or propose a better one — and defend it using at least two Week-2 ideas (the mechanism, the ethical stakes, what the word implies about who's responsible).
• Part 2 — Diagnose a confident mistake. Here is an AI answer to "What are some reliable statistics on the effect of social media on teenage mental health?":

"According to a 2022 meta-analysis by Dr. Sarah Chen and colleagues published in the Journal of Adolescent Health (vol. 47, pp. 112–128), 78% of teenagers who used social media for more than 3 hours daily reported clinically significant depression symptoms. The study reviewed 42 clinical trials and is considered the gold standard in the field."

Name at least two specific details in this answer that should make you suspicious, and explain why the model produced them — connecting your diagnosis to the token-prediction mechanism.

Replies (by Sunday, Sep 14). Reply to at least two classmates. Don't just agree — challenge their verdict on the word choice with an angle they didn't consider, or point out a suspicious detail they missed in the error-analysis.

What a strong post looks like: "I'd call 'hallucination' a useful but imprecise shorthand: it captures the 'confident mismatch with reality' idea, but it implies the model did something unusual, when the mechanism (predict likely text) is exactly the same whether the output is true or false. The word risks letting us treat every wrong answer as a glitch instead of a predictable design outcome — which means we may not check as carefully as we should. In the social-media answer, two red flags stand out: Dr. 'Sarah Chen' and the specific volume/page range. The model produces these because plausible author names and precise journal metadata are exactly what real citations look like — it's predicting the form of a citation, not verifying a real one."

Why this matters: the word you use to describe a problem shapes how you respond to it. If hallucination is a glitch, you wait for the glitch to be fixed. If it's a predictable feature of how the technology works, the responsibility to verify is always yours.

Integrity & AI note. Write your post in your own words — the critical thinking is the point. You may use an approved assistant to brainstorm, but the analysis you post must be your own; if AI helped, add a one-line note saying which tool and how. (Note: this is the traditional format. In this course's actual adaptive discussion, working through the word debate and the diagnosis with the assistant is the activity — see G-discussion-week-02.md.)

Participation rubric — 20 points

Grading note (Prof. Quinn): both verdicts — "hallucination is a useful word" and "hallucination is misleading" — are fully defensible. Grade the quality of the argument and the precision of the diagnosis, not the position taken. The error-analysis answer should name specific details (author name, volume/page, specific percentage) and explain that the model is predicting what a citation looks like — not fabricating it "on purpose."
