Teaching Argument & Evidence-Based Writing (Workshop)

Making a claim and backing it with evidence and reasoning is one of the most important, and most demanded, forms of writing, yet students often assert without supporting. Teaching argument writing well builds students who can reason, persuade, and think clearly on paper.

Key takeaway

Argument writing, making a claim and backing it with evidence and reasoning, is heavily demanded but hard; teaching it well builds students who can reason, support claims, and think clearly, not just assert.

Why it works

Argument and evidence-based writing, stating a clear claim and supporting it with relevant evidence and sound reasoning (while addressing counterarguments), is central to academic writing and standards, and it is cognitively demanding: students often assert opinions without evidence, misuse or fail to explain evidence, and ignore counterarguments. Teaching it well means explicitly teaching the elements (claim, evidence, reasoning, counterargument), using mentor texts, teaching students to select and explain evidence (not just drop quotes), and scaffolding the reasoning that links evidence to claim, across subjects, since argument is disciplinary.

The research: Research on argument writing; writing standards.

    The core activity: teach claim, evidence, and reasoning

    Teachers leave with argument writing taught through its elements and reasoning.

    Claim, evidence, reasoning, not just assertionArgument writing builds reasoning and clear thinking. Teach the elements explicitly, and especially the reasoning that links evidence to the claim, across subjects.

    Facilitator notes

    Asserting without evidence is not argumentOpinions without evidence, or dropped quotes without reasoning, are not argument. Teach claim, evidence, reasoning, and counterargument explicitly.

    Common questions

    Why do students struggle with argument writing?
    They often assert opinions without evidence, drop quotes without explaining them, and ignore counterarguments. Teach the elements explicitly, claim, evidence, reasoning, counterargument, and how they connect.
    What is the hardest part?
    Usually the reasoning that links evidence to the claim, and selecting and explaining evidence rather than just quoting it. Scaffold the reasoning, not just the structure.
    Isn't argument just for English class?
    No. Argument and evidence-based writing is disciplinary, scientists, historians, and others argue from evidence. Teach it across subjects, in each field's way.
