Teaching Critical Writing Across Disciplines
Writing that shows how a claim links to evidence helps students learn new content and communicate what they know. A meta-analysis of 56 experiments across science, social studies, and mathematics reported positive effects on learning when students wrote about content with clear tasks and feedback.
Programs that weave short writing prompts into large STEM courses, such as MWrite at the University of Michigan, report gains in disciplinary reasoning when drafting, peer review, and revision are part of weekly routines.
This article offers a practical, research-anchored guide for teaching critical writing in any field—humanities, social sciences, STEM, and health programs—using portable models, focused questioning, and clear assessment tools.

What “critical writing” means in plain terms
Critical writing makes thinking visible. The writer:
-
Poses a clear claim
-
Selects evidence that fits the audience and task
-
Explains the link between the two
-
Anticipates limits or counter-points
Three models make this concrete in class:
-
Paul–Elder for the quality of reasoning
-
Toulmin for the shape of argument
-
Claim–Evidence–Reasoning (CER) for concise empirical explanation
Each one has strong classroom support and open resources.
Shared language for reasoning: the Paul–Elder framework
Elements and intellectual standards
Students learn faster when they share a small set of labels for reasoning. Paul–Elder names the Elements of Thought (purpose, question, information, inferences, concepts, assumptions, implications, point of view) and Intellectual Standards (clarity, accuracy, precision, relevance, depth, breadth, logic, fairness).
Class move
Give a one-page card with the elements and standards. Ask students to mark one assumption and one implication in a paragraph before revising a sentence for clarity and relevance. This quick routine builds a habit that carries into any report or essay.
How arguments hold together: the Toulmin model
From claim to rebuttal
Toulmin’s schema helps writers build arguments that hold up under scrutiny: claim, data/grounds, warrant, backing, qualifier, rebuttal. It fits essays, policy briefs, and debate writing. Clear university guides and the Purdue OWL outline the parts and give examples across genres.
Class move
Take a paragraph from a policy article and label each part. Then assign a 200-word brief where students must add a rebuttal paragraph and a qualifier on scope.
Fast structure for empirical writing: CER
A small pattern with big payoff
CER asks students to write a claim, cite evidence, and explain the reasoning. The framework grew with work by McNeill and Krajcik and appears often in resources tied to NGSS practice.
Class move
Use CER as a lab exit ticket: one sentence for the claim, two data points, one reasoning line that names a limitation. This works for design memos in engineering, field notes in geography, or market analysis in business.
Questioning skills: the engine of strong drafts
Prompts that trigger reasoning
Richer writing starts with better questions. Try prompts that target one reasoning move:
-
Assumptions: “What hidden assumption supports your step?” (Paul–Elder)
-
Evidence: “Which result most strongly supports the claim, and why?” (CER)
-
Counter-case: “What example would weaken this warrant?” (Toulmin)
Use wait-time
After asking, pause for at least three seconds. Longer pauses raise the length and complexity of responses and shift talk from teacher to students. The effect appears across summaries of classroom talk research.
Where writing looks different, but thinking rhymes
Humanities and social sciences
Common tasks: interpretive essays, literature reviews, policy briefs. Toulmin helps students add warrants, qualifiers, and rebuttals rather than stacking quotes.
Sciences and engineering
Common tasks: lab reports, research papers, design notes. IMRaD (Introduction, Methods, Results, Discussion) sets the section flow, and CER helps students write short, precise explanations inside those sections.
Health programs
Clinical notes use SOAP (Subjective, Objective, Assessment, Plan). Students practice concise observation and reasoning that supports a diagnosis and plan. University writing centers and peer-reviewed summaries outline the structure and purpose.
Writing across the curriculum (WAC) and writing in the disciplines (WID)
WAC treats writing as a tool for learning across courses. WID adapts tasks to the genres of each field. Campus WAC pages lay out assignment design, scaffolding, and feedback strategies that fit large and small classes. Guides for writing in specific disciplines help students match expectations in history, psychology, engineering, and more.
Assignment blueprints you can run this term
Blueprint A: Science or engineering (IMRaD-aligned)
Task
Data commentary (200–300 words). Students receive a graph and write: one claim, two pieces of evidence, one reasoning line with a limitation.
Why it works
The CER form makes the logic visible and fast to grade. IMRaD guides help students plug the paragraph into a Results-Discussion bridge later.
Task
Method choice memo (150–200 words). Pick one design choice, state the rationale, name one assumption, add one counter-scenario.
Why it works
Paul–Elder standards and elements give the language for accuracy and relevance checks.
Blueprint B: Social sciences or policy
Task
Policy brief (1–2 pages). Use the Toulmin model with a required rebuttal and a short qualifier on generalization.
Why it works
Readers see the logic chain and the limits. Purdue OWL offers accessible practice tips.
Blueprint C: Humanities
Task
Source-based argument. Students annotate two articles for warrants and counter-arguments, then write one focused paragraph that uses those notes.
Why it works
Toulmin keeps focus on reasoning rather than summary.
Blueprint D: Health and clinical
Task
SOAP progress note. Students fill S/O/A/P for a case, justify the assessment with one guideline or study, and set monitoring criteria in the plan.
Why it works
SOAP mirrors workplace documentation and builds concise reasoning.
Scaffolding that helps students move from idea to draft
Model → prompt → draft → review → revise
-
Model a paragraph with labeled moves (claim, evidence, reasoning, limitation).
-
Add a challenge question that points at a single standard, such as clarity or relevance.
-
Draft in short bursts—5 to 10 minutes tied to one concept. This matches writing-to-learn studies that use brief, frequent tasks.
-
Peer review that trains reviewers. Students learn by giving feedback, not only getting it. Experiments with college writers show reviewers outperform readers and controls on follow-up tasks.
-
Revision with a reasoning log. Students list the change and the comment or source that prompted it.
Tip for setup
A short rubric that mirrors your model—CER or Toulmin—keeps comments focused and avoids vague advice.
Peer review that teaches the reviewer
A randomized study found that undergraduates who reviewed peer work wrote better than students who only read sample papers or received no treatment. Comments that identified a problem and offered a fix correlated with gains. Follow-up work and reviews in higher education echo this pattern and offer design pointers for training reviewers.
Design choices that help
-
Three reviews per draft strikes a good balance for time and learning, based on recent survey work on peer grading practices.
-
Score the quality of the review with two or three lines on accuracy and usefulness.
-
Provide sentence stems for comments: “The claim is…,” “Evidence supports the claim when…,” “A stronger warrant would…”.
Feedback that builds self-regulation
The seven widely cited principles of good feedback practice support learning: clarify goals, provide information on current performance, suggest next steps, encourage self-assessment, promote dialogue, support motivation, and feed teaching decisions. The model scales to peer review and comment banks.
Class move
Turn these principles into a template. Ask peer reviewers to select one goal, point to a line in the draft, and offer one next step the writer can try in 10 minutes.
Assessment that stays consistent across sections
Start with AAC&U VALUE rubrics
VALUE rubrics for Written Communication and Critical Thinking are open educational resources. Departments can adopt them as a common baseline and then add two or three genre-specific rows.
Examples of local rows
-
IMRaD: methods transparency, data-to-claim linkage
-
Policy brief: feasibility and stakeholder implications
-
SOAP: diagnostic justification and monitoring plan
Shared rubrics help multi-section courses keep expectations clear for students and teaching teams.
Inclusive support for multilingual and first-gen writers
Language frames for reasoning
Offer sentence starters for warrants and limitations:
“This suggests ___ since ___.”
“A plausible alternative is ___ which would change ___.”
These frames map cleanly to Paul–Elder standards and work across disciplines.
Visual aids
Provide one-page maps of Toulmin and CER with short examples from your field. Many open guides show the parts and their functions.
Time to think
Keep wait-time in seminars and labs. The extra pause draws in quieter students and raises the average complexity of answers, which later appear in stronger drafts.
Real classrooms, real adjustments
Large first-year chemistry
A lecturer replaced one recap slide each week with a CER exit ticket on a current topic. Students posted a claim, two data points, and a reasoning line. Later, selected examples opened the next class for five minutes of discussion. Grades improved on short-answer exam items that required explanation. This mirrors writing-to-learn research and the MWrite approach.
Policy course with mixed majors
A brief on local transport policy used the Toulmin pattern. One paragraph had to name a counter-example and quantify limits. Students reported that the required rebuttal paragraph stopped them from cherry-picking sources, a common problem in early drafts. Purdue OWL resources supported the structure.
Nursing simulation
Students completed SOAP notes after each simulation. Peer reviewers checked the Assessment line for a clear link to Subjective and Objective findings and asked for a monitoring criterion in the Plan. Faculty noted tighter diagnostic language over the term, consistent with SOAP guidance and writing center handouts.
One-week starter plan for any discipline
Day 1: Shared language
Mini-lesson on the Paul–Elder elements and standards. Students annotate a short paragraph for clarity, relevance, and logic, then revise two sentences.
Day 2: Argument parts
Walk through a field-specific example using Toulmin. Students label claim, data, warrant, qualifier, and rebuttal.
Day 3: Evidence moves
Run three CER exit tickets linked to figures, excerpts, or cases. Students must include one limitation with their reasoning.
Day 4: Peer review
Train reviewers with a four-question form and grade the review quality. Students learn through giving feedback.
Day 5: Revision
Students submit a revision plus a short reasoning log that lists what changed and why, using the feedback principles as headings.
Conclusion
Across subjects, students learn content and communicate more clearly when courses make reasoning explicit in writing. A small toolkit—Paul–Elder for quality, Toulmin for structure, CER for concise explanation—gives instructors and students a shared map.
Short writing-to-learn tasks, trained peer review, and steady use of wait-time create the conditions for stronger drafts.
Shared rubrics keep grading consistent across sections. These steps fit lectures, labs, studios, and clinics, and they build habits that students carry into work and community life.
FAQs
1) What is the fastest way to start in a content-heavy course?
Swap one recap slide each week for a 5-minute CER exit ticket. Use a two-line checklist for feedback. Frequent, brief writing-to-learn tasks tied to core ideas work well.
2) How should I choose between Toulmin and CER?
Match the task. CER fits lab reports and data-based explanations. Toulmin fits policy briefs, literature reviews, and debates that need warrants, qualifiers, and rebuttals.
3) Does peer review help the reviewer, not only the writer?
Yes. Studies with college writers show reviewers gain skill when they identify problems and offer specific fixes.
4) What rubric keeps multi-section grading consistent?
Adopt AAC&U VALUE rubrics for Written Communication and Critical Thinking, then add two or three rows for your local genres, such as methods transparency or diagnostic justification.
5) How can discussion support better drafts?
Ask one probing question and pause for three to five seconds. Longer, more reasoned responses often translate into clearer writing.
