Week 7 — Lecture Outline · Argument: Claims, Evidence & Warrants (Toulmin)

English Composition · ENGL 1A Fall 2026 · Prof. Lindgren Fictional sample

Course: English Composition (ENGL 1A) · Silver Oak University (fictional sample) · Prof. Lindgren
Objectives covered: Objective 4 — Compose in multiple rhetorical modes, using the appeals and the structure of argument (claim, evidence/grounds, warrant, counterargument, rebuttal).
SLOs touched: A (develop and support an argument using appropriate rhetorical strategies)
Meeting pattern: 2 sessions × 75 min = 150 min. Segment minutes below total ~150; scale to your own pattern.

Last pre-midterm week + a major-essay week. This outline drives the Argument Essay (Assignment 7) and feeds directly into the Week 8 midterm. Leave class time to point students at the essay and the studio.

Week at a Glance
The week's big question "What is my claim, what's my evidence, and what unstated assumption (the warrant) connects them — and what would the smartest person on the other side say back?"
By the end of the week, students can… (1) name the Toulmin parts — claim, grounds/evidence, warrant (plus backing, qualifier, rebuttal) — and explain how the warrant links evidence to claim; (2) tell an arguable claim from a fact or a topic; (3) add a counterargument (steel-manned) and a rebuttal; (4) identify common logical fallacies; (5) explain why evidence alone isn't an argument.
Key vocabulary argument, claim/thesis, grounds/evidence/data, warrant, backing, qualifier, counterargument/counterclaim, rebuttal, arguable, steel-man vs. straw-man; the appeals (ethos/pathos/logos) in service of a thesis; logical fallacy — ad hominem, straw man, slippery slope, false dilemma (either/or), hasty generalization, appeal to authority (misused), bandwagon (ad populum), circular reasoning (begging the question), post hoc
Materials slides (Deck 7); the week's readings (Purdue OWL on the Toulmin model + the arguable thesis + logical fallacies) + the CrashCourse "How to Argue" video; one approved chatbot (Gemini / Claude / ChatGPT) for the AI-critique moment and the tutorial
Timing note 8 segments, ~150 min total. Session 1 = Segments 1–4 (~75). Session 2 = Segments 5–8 (~75).

Segment 1 — Hook & the Promise (8 min) · Session 1 opens

Hook. Put one sentence on a slide: "We should make the campus shuttle free." Then ask: "Okay — is that true?" Watch the room hesitate. It's not true or false the way "the shuttle costs $2" is. It's a claim — a position someone could reasonably dispute. Now ask: "What's your evidence?" Someone says, "Lots of students can't afford it." Push once more: "And why does that prove the shuttle should be free?" That last question — the one that's hard to answer — is the warrant, the hidden assumption holding the whole thing together.

Then: "For six weeks you've been getting ready to do exactly this — make an argument and defend it. Today we learn what an argument is actually made of, so you can build one that holds and spot one that doesn't."

The promise (write it on the board): "By Friday you'll take any claim apart into claim / grounds / warrant, answer the other side with a rebuttal, and name a fallacy on sight."

Why it matters line (memory hook): "Anyone can have an opinion. An argument is an opinion plus its evidence plus the reason that evidence counts — and a fair answer to the other side."

Segment 2 — The Toulmin Model: Claim, Grounds, Warrant (24 min)

Plain language first. Philosopher Stephen Toulmin gave us the most useful X-ray of an everyday argument. Every real argument has three core parts:

  • Claim — the position you're asking your reader to accept. (It's your thesis, stated as something arguable.)
  • Grounds (also evidence or data) — the support: the facts, examples, data, or reasons you offer.
  • Warrant — the assumption that links the grounds to the claim — the reason your evidence actually counts as support for this claim. It is often unstated (implied), which is exactly why arguments quietly fall apart there.

Memory hook (put it on a slide):

"Claim = the point. Grounds = the proof. Warrant = why the proof proves the point."

One fully worked example (do it out loud — the everyday version):

  • Claim: There's a dog nearby.
  • Grounds: I hear barking and howling.
  • Warrant (usually unspoken): Barking and howling are sounds dogs make — so if I hear them, a dog is probably near.

Notice the warrant is obvious here, so nobody states it. But it's still doing the work: if the "barking" turned out to be a sound effect from a speaker, the warrant fails and the claim collapses. The warrant is where an argument is strong or weak.

Now the three optional parts (one line each):
- Backing — extra support for the warrant (when the warrant itself might be questioned).
- Qualifier — a word that limits the claim's scope: probably, in most cases, usually, presumably. (Honest arguers qualify; it builds credibility.)
- Rebuttal — an acknowledgment of a valid opposing view, and your answer to it. (We build this in Segment 5.)

The move students must internalize:

Evidence alone is not an argument. A pile of facts proves nothing in particular until a warrant says what they're evidence for. The link is the argument.

Segment 3 — What Makes a Claim Arguable (18 min)

Plain language first. You can only argue a claim — and not every sentence is one. Three things people confuse with a claim:

  • A fact is not a claim: "The library closes at 10 p.m." Nobody disputes it; there's nothing to argue.
  • A topic is not a claim: "social media and teenagers" is a subject, not a position. A claim takes a stance on the topic.
  • A personal taste is a weak claim: "pineapple on pizza is gross" can't be argued from shared evidence — it's just preference.

An arguable claim is a position that reasonable people could disagree about and that you could support with evidence.

One worked example (do it at the board):

  • Topic: school phone policies.
  • Not a claim (fact): "Most students own a smartphone."
  • Arguable claim: "Silver Oak should require phones to be off and away during lectures." → reasonable people disagree; you can marshal evidence (attention research, classroom experience, fairness) and warrants.

Memory hook:

"If no one could reasonably disagree, it's not an argument — it's a fact or a topic. A claim takes a side you have to earn."

Quick interaction (~5 min): Put six sentences on a slide (mix of facts, topics, and arguable claims). Students call out, for each: fact, topic, or arguable claim — solo (30 sec), then with a neighbor (1 min). Debrief the close calls.

Segment 4 — Logical Fallacies + Quick Interaction (25 min) · Session 1 closes (~75)

Plain language first. A logical fallacy is a move that looks like reasoning but isn't — a broken link between evidence and claim, or a dodge. Learn them to avoid them in your own writing and to catch them in others'. Teach these nine (definitions are exact; use the instructor's own one-line examples):

  • Ad hominem — attacking the person instead of their argument. "You can't trust her budget plan; she failed a math class once."
  • Straw man — distorting the opponent's view into a weaker version, then knocking that down. "People who want a later start time just want to sleep all day."
  • Slippery slope — claiming one small step will inevitably lead to an extreme outcome, with no evidence for the chain. "If we allow phones in one class, soon no one will ever pay attention to anything."
  • False dilemma (either/or) — pretending there are only two options when more exist. "Either we cut the arts program or the school goes bankrupt."
  • Hasty generalization — drawing a broad conclusion from too little evidence. "Two of my professors were late, so professors here don't care about time."
  • Appeal to authority (misused) — treating someone's say-so as proof when they're not an expert on the question (or just citing "experts" with no actual evidence). "A famous actor says this diet works, so it must."
  • Bandwagon (ad populum) — claiming something is true or right because many people believe or do it. "Everyone's switching to this app, so it must be the best."
  • Circular reasoning (begging the question) — restating the claim as if it were the evidence. "This policy is the fairest because it's the most just."
  • Post hoc — assuming that because B followed A, A caused B. "I wore these socks and we won, so the socks won the game."

Memory hook:

"A fallacy is a counterfeit argument — it has the shape of reasoning with none of the substance. Spot the broken link."

Interaction — Name That Fallacy (rapid-fire, ~8 min): Put five short passages on a slide (instructor's own, no fabricated quotes). For each, students name the fallacy — solo, then neighbor-check. Debrief why each breaks: what's the missing link, or what's the dodge?

Segment 5 — Worked Move: Map an Argument, Then Add Counter + Rebuttal (22 min) · Session 2 opens

Hook back in: "Last session: the parts of an argument and the fallacies that fake them. Today we build one — map a claim to its grounds and warrant, then do the move that separates strong writers from loud ones: take on the other side."

One fully worked example (do it at the board, thinking aloud — instructor's own argument):

Topic: a campus-everyday issue — whether the dining hall should stay open later on weeknights.
- Claim: The dining hall should stay open until midnight on weeknights.
- Grounds: Many students study late and the only late option is vending machines; a campus survey showed late-night demand; nearby dorms house first-years without kitchens.
- Warrant (now stated): A campus food service should be available when a large share of students actually need to eat — and late-studying students are a large share.
- Backing (supports the warrant): The dining hall's mission statement already commits to "meeting students where they are."

Now add the other side — and answer it:

  • Counterargument (steel-manned): "Staying open later means real costs — extra staffing and utilities — and only a minority eat that late, so the money would serve more students if spent elsewhere." (State it as the other side's best case, not a cartoon.)
  • Rebuttal: "The cost is real, but a limited late window — say a grab-and-go counter, not the full hall — meets the need at a fraction of the cost, and the survey shows the 'minority' is large enough to matter for first-years with no kitchen."
  • Qualifier added for honesty: "The dining hall should probably stay open later on weeknights during the semester" — scoping the claim makes it defensible.

Name the moves: found the claim; gathered grounds; stated the warrant (don't leave it buried); steel-manned the opposition; answered with a rebuttal; qualified the claim. That's an argument that holds.

Misconception + cure:
- ❌ "Mentioning the other side makes my argument look weak."
✅ Cure: the opposite. Answering the strongest counterargument shows you've thought it through and builds your credibility (ethos). Ignoring it leaves a hole any reader can see.

Segment 6 — The Appeals in Service of a Thesis (15 min)

Plain language first. Week 6 taught ethos, pathos, logos as how a text persuades. In your argument, the appeals are tools serving your claim, not decorations:

  • Logos — your grounds + warrants: the logical spine. This carries an academic argument.
  • Ethos — your credibility: built by fair use of evidence, by qualifying honestly, and by steel-manning the other side.
  • Pathos — emotional resonance: legitimate when it's proportionate and honest (a real stake, a human example), a fallacy when it replaces evidence (fear-mongering, a tearjerker with no logic behind it).

The balance to teach: in college argument, logos leads; ethos and pathos support. An argument that's all pathos slides toward fallacy; an argument with no human stakes can read as bloodless. Match the appeals to your audience and your claim.

Quick interaction: take the dining-hall argument and ask: where's the logos (the survey + warrant), the ethos (acknowledging the cost honestly), the pathos (a first-year with no kitchen at 11 p.m.)? Name each.

Segment 7 — Building the Argument Essay + Technology Workflow (22 min)

Plain language first. The Argument Essay (this week's major assignment) is where all of this becomes a paper. The shape:

  • Intro → arguable thesis (your claim). End the intro with a sharp, qualified claim.
  • Body paragraphs = grounds + warrants. Each paragraph: a reason (mini-claim), evidence, and the warrant that says why it counts. Don't drop a quote and run — explain the link.
  • A counterargument + rebuttal section (or woven in): the strongest opposing view, steel-manned, then answered.
  • Conclusion: what follows if the claim holds — the stakes, not just a restatement.
  • Pick a defensible, classroom-appropriate, arguable topic — campus, everyday, or policy. You may argue a side you don't personally hold; that's a skill, not a betrayal of your beliefs.

Technology workflow — the word processor + a chatbot, used the right way:
1. Draft in a word processor. Map your claim / grounds / warrant before you write paragraphs (the studio walks you through this).
2. Use a chatbot to pressure-test, not to author: "What unstated warrant am I assuming between this evidence and this claim?" or "What's the strongest counterargument to my thesis?" Then you decide and write.
3. Never paste a chatbot's argument in as your own — its reasoning is generic, it straw-mans the opposition, and when it reaches for support it may invent a quotation or a source.

AI-critique moment (students verify, not consume):

Paste this to an approved chatbot: "Write a one-paragraph argument that [your essay's claim], and include a source."
Then read it critically. Hunt for: (a) a warrant gap — does the evidence actually connect to the claim, or is there a leap? (b) a fallacy — did it straw-man the other side, slide down a slippery slope, or pose a false dilemma? (c) hollow reasoning — confident sentences that say nothing. (d) a fabricated quotation or source — if it cited anything, can you find that exact quote at that exact source? (Usually you can't.) The habit all term: the tool drafts, you judge — and in an argument, you judge the reasoning, not just the grammar.

Segment 8 — Callback, Tease & Hand-off (15 min) · Session 2 closes (~75)

Callback + tease:
- Callback: "Six weeks ago we said writing is for a reader. Now you're asking that reader to change their mind — which means meeting them with evidence, a stated warrant, and a fair hearing for their side."
- Tease next week: "Next week is review and the midterm — cumulative across Weeks 1–7: the rhetorical situation, summary and response, the paragraph, thesis and structure, the modes, the appeals, and this week's argument machinery. The Argument Essay you write this week is the best possible studying for it."

Hand-off (the week's graded work):
- Lecture Tutorial 7 (AI tutor, share-link submission) — claim/grounds/warrant, counterargument & rebuttal, the fallacies.
- Quiz 7 (end of week) and Discussion 7 ("Is using AI to draft an essay cheating, a tool, or both?").
- Assignment 7 — the ARGUMENT ESSAY (major essay, 100 pts) — arguable thesis, evidence + warrants, counterargument + rebuttal.
- Writing Studio 7 ("Map Your Argument, Then Argue the Other Side") — diagram claim → grounds → warrant, add counter + rebuttal, review, then coach + critique with a chatbot.

Instructor FAQ — Common Stumbles

Student says / does Quick cure
"What even is a warrant?" It's the assumption that links your evidence to your claim — the reason the evidence counts. Ask: "For this evidence to prove this claim, what would I have to already believe?" That belief is the warrant.
Treats a fact or a topic as a thesis. A claim takes a side reasonable people could dispute. "Phones distract students" (arguable) vs. "Students own phones" (fact) vs. "phones in school" (topic).
"Why bring up the other side at all?" Answering the strongest counterargument builds ethos and closes the hole a reader would otherwise find. Ignoring it is the weakness, not naming it.
Straw-mans the opposition. If the other side wouldn't recognize their own view in your version, you've built a straw man — and beating it proves nothing. State their best case first.
Drops a quote/stat and moves on. Evidence alone isn't an argument. Name the warrant: say why this evidence supports this claim. The link is the argument.
Confuses slippery slope with a real causal chain. A slippery slope asserts an extreme outcome without evidence for the steps. A real causal argument shows each link.
Thinks winning = good argument. Good argument is honest reasoning fairly presented, not the loudest or most one-sided. Steel-man, don't straw-man.
Pastes a chatbot's argument as their own. Its reasoning is generic, it straw-mans, and it may invent quotes/sources. Use AI to pressure-test (find my warrant gap, name my counterargument); the writing and judgment are yours.

Scope flag

This outline stays within Objective 4 (the structure of argument: claim/grounds/warrant, counterargument and rebuttal, the appeals in service of a thesis, and logical fallacies). Research — finding, evaluating, and integrating sources is Weeks 9–10; MLA documentation is Week 11; the research-based argument (argument + sources together) is Week 12. So this week's essay argues from the student's own reasoning and everyday/observed evidence — not a formal source-and-citation paper (that comes after the midterm). All example arguments and fallacy passages here are the instructor's own illustrations, attributed to no one; no real author is quoted. The fallacy definitions match the standard treatments in the linked Purdue OWL and Excelsior OWL pages. Next week (W8) is review + the midterm, which is cumulative over Weeks 1–7.
