How to use this page

Everything here is a link to an external resource — open it in your browser, the same way you'd open a YouTube link. Nothing needs to be downloaded, and there is nothing to buy.

This week's load is 3 short readings + 1 video, grouped by the three big ideas — (1) the structure of argument (Toulmin), (2) the arguable claim, and (3) logical fallacies — plus one optional free reference. Read or watch one item per group and you're ready for the quiz; do all of them and you'll be very comfortable for both the quiz and the Argument Essay. Total time is roughly 35–45 minutes if you do everything, far less if you pick one per group.

Reading order that matches the lecture: ① the Toulmin parts (claim → grounds → warrant) → ② what makes a claim arguable → ③ the fallacies to avoid and to catch.

A habit to start now: when you read any argument this week — including your own draft and anything a chatbot writes for you — stop at each piece of evidence and ask the warrant question: "Why does this evidence prove this claim?" If you can't answer, the argument has a gap.

① The Structure of Argument — the Toulmin Model

Maps to Lecture Segments 2 & 5. Every argument has a claim (the position), grounds/evidence (the support), and a warrant (the assumption linking them) — plus optional backing, qualifier, and rebuttal.

Reading — "Toulmin Argument" (Purdue OWL)
🔗 https://owl.purdue.edu/owl/general_writing/academic_writing/historical_perspectives_on_argumentation/toulmin_argument.html
Why it's assigned: the clearest short explanation of the model we built in class — claim, grounds, warrant, then backing, qualifier, and rebuttal — with the simple "there's a dog nearby" example that makes the warrant click. This is the core reading for the week.
⏱ ~8 min

Optional companion — "Organizing Your Argument" (Purdue OWL)
🔗 https://owl.purdue.edu/owl/general_writing/academic_writing/establishing_arguments/organizing_your_argument.html
Why it's here: lays the Toulmin method beside two other ways to organize an argument and gives a fully worked Toulmin example (claim → data → warrant → counterclaim → rebuttal). Handy as you plan the Argument Essay.
⏱ ~7 min

② What Makes a Claim Arguable

Maps to Lecture Segment 3. A claim is a position reasonable people could dispute and that you can support with evidence — not a fact, not just a topic, not a matter of taste.

Reading — "Developing Strong Thesis Statements" (Purdue OWL)
🔗 https://owl.purdue.edu/owl/general_writing/academic_writing/establishing_arguments/index.html
Why it's assigned: the standard guide to the debatable (arguable) thesis — why "Pollution is bad for the environment" can't be argued but a focused, debatable claim can — plus the four types of claims (fact/definition, cause and effect, value, policy) and how qualifiers narrow a claim. This is the move at the heart of your essay.
⏱ ~7 min

③ Logical Fallacies — the Counterfeit Arguments

Maps to Lecture Segment 4. A fallacy is a move that looks like reasoning but isn't. Learn them to avoid them in your own writing and to catch them in others' (and in a chatbot's).

Reading — "Logical Fallacies" (Purdue OWL)
🔗 https://owl.purdue.edu/owl/general_writing/academic_writing/logic_in_argumentative_writing/fallacies.html
Why it's assigned: a clean, example-by-example list of the common fallacies we named in class — slippery slope, hasty generalization, post hoc, circular argument, either/or, ad hominem, bandwagon (ad populum), straw man, and more — each with a short example. Use it as your fallacy reference all week.
⏱ ~8 min

Optional companion — "Logical Fallacies" (Excelsior OWL)
🔗 https://owl.excelsior.edu/argument-and-critical-thinking/logical-fallacies/
Why it's here: a second, friendly walkthrough of the same fallacies from a free, college-run writing lab — a good cross-check if a definition hasn't quite landed. (Excelsior also has a short Toulmin page under Argument & Critical Thinking if you want one more pass on the model.)
⏱ ~6 min

Video — "How to Argue – Philosophical Reasoning: Crash Course Philosophy #2" (CrashCourse)
🔗 https://www.youtube.com/watch?v=NKEhdsnKKHs
Why it earns the click: a lively, fast tour of what an argument actually is — premises, a conclusion (your claim), and what makes the link between them hold up or break down. It's the logic spine under the Toulmin model, in plain language.
⏱ ~9 min

Optional one-stop reference (free online text)

If you'd like one optional reference to skim, the OpenStax Writing Guide with Handbook keeps its full text free to read online and has a strong chapter on argument (position arguments, claims, reasons, and evidence) and on rhetorical strategies — a reputable, currently-available college writing reference.
🔗 https://openstax.org/details/books/writing-guide
Why it's here: a free, returnable reference for the whole course — entirely optional this week. (Linked as a free reference; this course makes no open-license or copyright claim about it.)

Pick-one quick path (≈15 min total)

In a hurry? Do exactly these two and you'll be ready for the quiz:
1. Read "Toulmin Argument" (group ①) — get claim / grounds / warrant down cold.
2. Read "Logical Fallacies" (Purdue OWL) (group ③) — skim the example for each fallacy.

Heads-up (links rot): these point to outside sites that occasionally move or rename pages. If a link ever fails, tell Prof. Lindgren and use the free OpenStax reference above in the meantime. Nothing here is hosted by our course — these are all external resources, linked, not reproduced.
