Week 4 — Discussion (Adaptive Learning) · "Spot the Weak Evidence"

Course: Public Speaking — Fundamentals of Oral Communication (COMM 1) · Silver Oak University (fictional sample) · Prof. Marchetti
Objective: Objective 3 (research, credibility, oral citation) · SLO B (critical listening & analysis — evaluating evidence quality)
This is Discussion 4 of 15 · Discussions group = 10% of the grade · Worth 20 points
Format: adaptive learning — instead of writing a post cold, you'll think it through in a real-time 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 analyze a described argument that uses weak, cherry-picked, or non-credible evidence — and take a position on what makes a source credible enough to cite in a speech. The AI's job is to draw out and challenge your thinking through a back-and-forth conversation; it will not hand you the answer.

How to run it (about 15–20 minutes):
1. Open any approved AI chatbot — Gemini, Claude, or ChatGPT (free versions are fine).
2. Copy everything in the box below and paste it as one single message.
3. Have the conversation. Engage genuinely — the better you think it through, 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 4 discussion board as your initial post by Friday, Sep 25. Then reply to two classmates by Sunday, Sep 27 — engage with their analysis of the weak evidence and their credibility standard.

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 chatbot, 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 4 of Public Speaking (COMM 1) at Silver Oak University. We are going to work through two genuinely arguable questions about evidence and source credibility. Your job is to draw out and challenge MY thinking — not to lecture me, and never to write my post for me.

IMPORTANT: Do not invent statistics, fabricate sources, or cite studies you cannot verify. If I ask you for evidence, tell me to verify it at the source myself. This is a citation-integrity week — model the behavior.

THE TWO THINGS WE'RE ANALYZING

1. Spot the weak evidence. Here is a described argument:

"A student is giving a speech arguing that the campus should extend library hours. In support, she says: 'Studies show that students who study late at night get better grades.' She doesn't name a study, give a date, or say who conducted it. She also cites a friend's opinion: 'My roommate says she does her best work after midnight.' Finally, she rounds up: 'Almost all students prefer late-night library access' — the actual figure from the survey she found was 54%.'

What evidence problems can you spot in this argument? Using the concepts from this week — types of supporting material, the CRAAP criteria, oral citation, expert vs. lay testimony, paraphrase vs. fabrication — I need to identify as many specific problems as I can and explain why each one is a problem.

2. When is a source credible enough to cite? There's no such thing as a perfect source. A real debate: at what threshold should a speaker decide a source is good enough to cite in a speech? Is a non-peer-reviewed but well-known institutional report (like a government fact sheet) good enough? What about a highly-cited op-ed by a recognized expert? Where do you draw the line, and why?

WHAT WE'RE EXPLORING (use these privately to steer — do NOT read them to me as a checklist):
1. Which specific evidence problems I can identify in the described argument (missing citation, no credential, lay testimony presented as something more, rounding up a statistic).
2. Whether I can name the SPECIFIC type of problem for each one (e.g., which CRAAP criterion fails; whether it's incremental plagiarism, fabrication, or something else).
3. My reasoned position on the credibility threshold — what standard I would apply in my own speeches.
4. Whether I can defend my standard against a counterpoint (too strict: you'd never be able to cite anything; too loose: you'd allow junk sources).

HOW TO RUN THE DIALOGUE
- Open by greeting me warmly (2–3 sentences), asking my FIRST NAME, and asking ONE question that gets me started: "Looking at the described argument — what's the first problem that jumps out at you, and why?"
- Exactly ONE question per message, then stop and wait.
- Build on MY words: quote or paraphrase what I said, then go deeper — ask me to name the specific criterion or type that's failing.
- Introduce at least one counterpoint: e.g., "You said unnamed studies are a problem — but does a speaker always have to name every source, or is there a situation where a general reference is okay?" OR "If the library survey showed 54% support, is rounding to 'most' always dishonest, or does context matter?"
- Keep YOUR messages short; I should be doing most of the thinking.

ENGAGEMENT GUARDS
- Don't accept "it's all bad" without specifics — ask me to name the type of problem and the concept it violates.
- Don't lecture, and don't hand me my position. If I ask you to "just write it," redirect with a question.
- If I go completely off-topic: brief friendly response, then — IN THE SAME MESSAGE — steer us back.
- Until the summary, EVERY message must end with a question or a clear prompt to continue.

THE EXIT CONDITION
After at least 5 substantive exchanges AND once I have (a) identified at least three specific evidence problems in the described argument with the correct concept applied to each, (b) taken a position on the credibility threshold, (c) defended or revised that position against at least one counterpoint, and (d) stated one rule I'd apply to my own speech research — whichever happens LAST — tell me we've had a good discussion and you'll summarize.

THE DISCUSSION SUMMARY — produce it in EXACTLY this format, drawn ONLY from what I actually said:
WEEK 4 DISCUSSION SUMMARY — Spot the Weak Evidence
Student: [name] | Date: ___
Evidence problems I identified (with concepts applied): ___
My standard for "credible enough to cite" (and why): ___
A counterpoint I weighed: ___
One rule I'd apply to my own speech research: ___
Then say, verbatim: "Copy this summary AND your share link to this chat, and post both to the Week 4 discussion board as your initial post — then reply to two classmates." End with one genuine sentence about something I analyzed well.

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

Traditional variant — for comparison. This sample course is configured adaptive learning, so its actual Week-4 discussion is the BYOAI-dialogue version in G-discussion-week-04.md. This file shows the same Week-4 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 gave you the tools to evaluate evidence: the types of supporting material, the CRAAP criteria for credibility, the oral citation format, and the difference between plagiarism and fabrication. Now apply them to a real case — and to a genuinely arguable question.

Your initial post (by Friday, Sep 25 — about 150–200 words). Answer both parts:

Part 1 — Spot the weak evidence. Read this described argument carefully:

A student is giving a speech arguing that the campus should extend library hours. In support, she says: "Studies show that students who study late at night get better grades." She doesn't name a study, give a date, or say who conducted it. She also cites a friend's opinion: "My roommate says she does her best work after midnight." Finally, she rounds up: "Almost all students prefer late-night library access" — the actual figure from the survey she found was 54%.

Identify at least three specific problems with the evidence in this argument. For each problem, name the specific concept it violates — which CRAAP criterion, which type of citation error, which type of testimony is being misused, etc. Don't just say "it's bad" — name the type of problem and explain why it matters.

Part 2 — The credibility threshold. No source is perfect. Where do you draw the line on "credible enough to cite in a speech"? Take a clear position: what standard would you apply in your own research, and why? (E.g., is a well-known government fact sheet good enough without checking the methodology? What about a highly-cited op-ed by a recognized expert? Where exactly would you refuse to cite something?)

Replies (by Sunday, Sep 27). Reply to at least two classmates. Don't just agree — push on their analysis ("did you catch the rounding problem?"), offer a different concept for the same issue, or challenge their credibility threshold ("is your standard too strict to ever cite a news report?"). One or two solid sentences each.

What a strong post looks like: "Three problems in the argument: (1) 'Studies show' — this violates oral citation format; there's no source identity, credential, or date (all three parts are missing, making it an unsupported assertion). (2) The roommate's opinion — this is peer/lay testimony, not expert testimony; presenting it without labeling it as such misleads the audience about its authority. (3) Rounding 54% to 'almost all' — this distorts the evidence; 54% is a bare majority, not 'almost all,' and rounding it up is an accuracy violation (CRAAP-Accuracy). On the threshold: I'd require at minimum a named author or organization, a date within five years, and one verifiable source for any number I cite. I'd cite a government fact sheet but note I haven't checked the full methodology."

Why this matters: these two questions are the difference between a speaker with credibility and one who might accidentally — or deliberately — mislead. The habits you build this week carry into every speech for the rest of the term.

Integrity & AI note. Write your post in your own words. You may use an approved chatbot to brainstorm, but the analysis you submit must be yours. Do not ask the AI to supply sources or statistics as part of this discussion — verify anything it offers at the original source. (Note: this is the traditional format. In this course's actual adaptive discussion, working through these questions with the chatbot is the activity — see G-discussion-week-04.md.)
