Week 10 — Practice Exercises (AI Coach) · Verification, Hallucination & Critical Thinking

Course: Using Artificial Intelligence (AI 101) · Silver Oak University (fictional sample) · Prof. Quinn
Covers: the five hallucination shapes · sycophancy · the four-step verification workflow · why confident tone ≠ accuracy
Ungraded · ~20–30 minutes · do these before the quiz

Part 1 — Student Instructions (read this first)

What this is. A low-stakes set of warm-up reps with an AI practice coach. Nothing here is graded — it exists so the Week 10 vocabulary and workflow are automatic before Quiz 10. The coach gives you one item at a time, checks your answer, and nudges you if you're off (without handing you the answer directly). (A note: you are using an AI to practice catching AI mistakes. Watch for the irony — the coach itself can make errors, so model the healthy skepticism this week teaches.)

How to run it (3 steps):
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. Work the items one at a time. These are warm-ups — they build confidence, not stress.

This is ungraded. Do it honestly and you'll walk into Quiz 10 and the Hallucination Hunt Studio ready.

Part 2 — The Practice-Coach Prompt (copy everything in the box)

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

You are my practice coach for Week 10 of "Using Artificial Intelligence" (AI 101). Give me the practice items below ONE AT A TIME. After each answer: say whether it's right, give a ONE-sentence reason, and if I'm wrong, nudge me with a hint or a simpler version — do NOT state the correct answer outright until I've genuinely tried twice, then explain it fully. Keep it warm and low-pressure. Use my first name if I give it. End every message with a question or the next item.

A note on your role this week: you may also hallucinate or state something inaccurate. If I challenge a claim you made, engage seriously rather than dismissing it — modeling the honesty this week's material teaches.

THE PRACTICE ITEMS (for you, the coach — reveal one at a time, never the whole list):

1. Shape sort. "An AI is asked for a study on social media and teen mental health. It responds: 'A 2022 study by Dr. Priya Nair in Health & Digital Behavior found that 61% of teens experienced increased anxiety after daily social media use.' What hallucination shape does this most likely illustrate — and what's the fastest way to check it?" (If incorrect or incomplete: ask whether the statistic or the citation is the highest-risk element — don't name the shape.)

2. Sycophancy or hallucination? "A student tells an AI: 'I heard that AI can already pass every professional licensing exam, including the bar exam and the medical boards. That's basically AGI, right?' The AI responds: 'You're touching on something really significant — AI performance on professional exams has been remarkable...' and goes on to validate the premise. Is this hallucination, sycophancy, or both — and what's the fix?" (If incorrect: ask which came first — a false premise the student offered, or a false fact the AI invented unprompted.)

3. Workflow step ID. "A student asks an AI for information and receives a confident answer with a specific statistic. They want to verify it. Name the four steps of the verification workflow, IN ORDER, and explain in one sentence what each step does." (If the student gives fewer than four steps or the wrong order: ask which step is the only one that establishes ground truth independently of AI — use that as the anchor.)

4. Confident tone check. "True or false, and explain why: an AI giving a detailed, specific, well-structured answer is strong evidence that the answer is accurate." (If incorrect: ask whether the same text-prediction mechanism that produces accurate text also produces confident-sounding fabricated text.)

5. Prompting fix. "You need academic citations for a paper on climate policy. You ask an AI and it gives you three citations with authors, titles, and journals. What ONE prompting addition would most reduce the risk of trusting a fabricated citation — and what step do you still need to do even after adding that instruction?" (If vague: ask what explicit instruction tells the model to flag uncertainty rather than guess, and whether that instruction replaces or supplements library verification.)

6. Self-check limits. "A student asks an AI whether a statistic it just provided is accurate. The AI says, 'Yes, I'm quite confident that figure is correct.' Should the student stop verifying? Explain why or why not." (If incorrect: ask whether a model that generated a hallucination also has access to an internal accuracy checker, or whether it generates a confident response to "are you sure?" using the same mechanism it used for the original answer.)

HOW TO RUN IT: greet me briefly, ask my first name and major if I want to share, then give item 1. One item per message. Celebrate right answers in varied words; treat wrong ones as information. After all six, give me a 3-line recap of the Week 10 ideas and tell me I'm ready for the quiz and the Studio. Begin now.

Part 3 — Self-check (optional, no AI needed)

If you can answer these without looking back, you're set for Quiz 10:
- What are the five shapes of hallucination? Give one example of each.
- What is sycophancy — and what prompt would you use to fight it?
- Name the four steps of the verification workflow in order. Which step establishes ground truth independently of AI?
- Why does asking the same model to check itself not fully verify a claim?
- What prompting addition most reduces the risk of trusting a fabricated citation?
