Argument Structure Scaffold Generator

What This Skill Does

Produces a genre-specific argument scaffold tailored to the student's level, the discipline, and the argument framework requested. The scaffold includes labelled structural sections, guiding prompts for each section, example sentence starters, and an annotated model showing the scaffold in use. Different disciplines argue differently — a scientific claim-evidence-reasoning argument has different structural requirements from a historical argument or a literary analysis — and this skill generates scaffolds that reflect those disciplinary differences rather than applying a generic "essay structure." AI is specifically valuable here because effective argument scaffolds must simultaneously encode the structural logic of the argument form, provide enough support to guide weaker writers without constraining stronger ones, and model the disciplinary conventions of the specific subject — a task that requires both writing expertise and subject-specific knowledge.

Evidence Foundation

Toulmin (1958) provided the foundational model of argument structure: claim (what you're arguing), data (evidence supporting the claim), warrant (the reasoning that connects data to claim), backing (support for the warrant), qualifier (limitations on the claim), and rebuttal (addressing counter-arguments). While Toulmin's full model is too complex for younger students, its underlying logic — that arguments require claims, evidence, reasoning, and acknowledgment of counter-positions — underpins all effective argument scaffolds. Graham & Perin (2007) in their Writing Next synthesis identified explicit teaching of writing strategies and text structures as one of the highest-impact interventions for adolescent writing (effect size 0.82), with argument structure instruction particularly effective. Andrews (2010) demonstrated that argumentation skills do not develop naturally — they must be explicitly taught through structured frameworks that make the components of argument visible. Hillocks (2011) showed that effective argument instruction requires students to understand the function of each component (why evidence matters, why counter-arguments strengthen rather than weaken), not just the sequence. Newell et al. (2011) found that argument instruction is most effective when it is embedded in disciplinary contexts rather than taught as a generic skill.

Input Schema

The teacher must provide:

• Argument topic: The claim, question, or proposition. e.g. "Should school uniforms be compulsory?" / "Was the Treaty of Versailles the main cause of World War II?" / "Does the evidence support the conclusion that increasing temperature increases enzyme activity?"
• Student level: Year group and writing level. e.g. "Year 9, can write paragraphs but struggle to structure a whole argument" / "Year 12, competent essay writers refining analytical depth"
• Scaffold type: The argument framework. e.g. "Toulmin" / "PEEL" / "Claim-Evidence-Reasoning (CER)" / "Historical argument" / "Balanced argument"

Optional (injected by context engine if available):

• Subject area: The discipline context
