How to Teach Argument Writing So Students Can Actually Construct a Claim

Argument writing is the most demanded and least understood writing type in school. Students know they need a thesis, evidence, and a conclusion. They can fill in those slots on a template. What they can't usually do is construct a genuine argument — a claim that takes a position, supported by reasoning that explains why the evidence actually proves the claim, and that addresses the strongest objection to its position.

The gap between "has a thesis and evidence" and "makes an argument" is large, and most writing instruction doesn't close it because it focuses on structure rather than on the thinking that structure is supposed to hold.

What an Argument Actually Is

An argument is not a topic, a summary, or a list of facts. An argument makes a claim that could be wrong — a position someone could reasonably dispute — and then provides reasons why the evidence supports that position rather than an alternative one.

The test for a real thesis: can someone reasonable disagree with it? "World War I caused significant suffering" is not a thesis — no one disagrees with it. "The assassination of Franz Ferdinand was less a cause of World War I than a pretext for conflicts that structural tensions made inevitable" is a thesis — someone could reasonably argue the opposite position. The thesis that can't be argued against isn't a thesis; it's a statement of fact.

Students who write on topics rather than about claims produce summaries that look like arguments because they have a thesis-shaped sentence at the top. The sentence doesn't do thesis work because it doesn't take a contestable position.

The Claim-Reasoning-Evidence Structure

Evidence use alone doesn't make an argument. Evidence makes an argument only when it's connected to a claim by reasoning — an explanation of why this evidence supports this claim rather than some other conclusion.

The C-R-E structure:

Claim: the specific, contestable position this paragraph is defending

Reasoning: an explanation of the logical connection between the evidence and the claim — why does this evidence prove the claim?

Evidence: specific, accurate evidence from the source

The order matters: reasoning before evidence (or interleaved with it) keeps the argument visible. Evidence before reasoning produces evidence-dumping, where quotes appear without any explanation of what they're doing there.

The question that generates reasoning: "Why does this evidence prove my claim rather than something else?" A student who can answer that question has the reasoning. A student who can't has evidence without an argument.

Teaching Students to Identify Their Own Claim

The student who writes a summary with a thesis at the top hasn't constructed a claim — they've named a topic. Teaching claim construction:

The "So what?" move: after a student writes a thesis, ask "so what?" What matters about this? What would be different if your claim were true versus false? The answer to "so what?" is usually where the real claim is.

The "I argue that" frame: require students to complete the sentence "I argue that..." before writing their thesis. "I argue that the New Deal saved American democracy" is a different thing from "The New Deal had many programs that helped Americans." The first is a claim; the second is a topic.

The "My opponent would say" test: if you can easily state what the opposing position is and why someone would hold it, you have a real claim. If there's no reasonable opposing position, you have a statement of fact.

Counterargument as Argument

The counterargument that most students write is a straw man they quickly knock over: "Some people think X, but they are wrong because Y." This isn't genuine engagement with the opposing view — it's a ritual bow toward the existence of disagreement.

Genuine counterargument acknowledges the strongest version of the opposing position and explains specifically why the arguer's claim is more defensible. Teaching genuine counterargument:

"What would someone who disagrees with you say? Not the weak version — the strongest version they could make. What's the most compelling evidence on their side? Now, why isn't that evidence enough to defeat your claim?"

Students who engage the strongest opposing argument produce more sophisticated arguments than students who knock down the weakest version, because the strong version forces them to think harder about why they're right.

The Role of Concession

Concession — acknowledging that the opposing view has some merit — is one of the most underused and most effective argument moves. A well-placed concession ("While it's true that X, this doesn't change the broader conclusion because...") demonstrates that the arguer has genuinely considered the other side, which increases credibility.

Students who make no concessions sound like they haven't engaged with the complexity of the issue. Students who make appropriate, controlled concessions sound like they have — because they have.

Teaching concession: identify one thing in the opposing argument that is genuinely true or worth acknowledging. Grant it explicitly, then explain why it doesn't defeat your claim. The concession should cost you something; if it doesn't, it's not a real concession.

Your Next Step

For your next argument writing assignment, add one requirement to the prompt: before submitting, students must complete this sentence in their notes (not in the essay): "The strongest argument against my thesis is ___, and I address it by ___." Students who can't complete this sentence don't have a real argument yet — they have a position they haven't tested. Requiring this self-check before drafting the counterargument section produces more genuine engagement with opposing views than any number of reminders to "include a counterargument." The question forces the thinking the counterargument is supposed to demonstrate.
