Why Paragraph Structure Must Be Explicitly Taught
The English Academic Paragraph Model
- Point (topic sentence): The main idea of the paragraph, stated directly.
- Illustration (evidence/example): Specific support for the point.
- Explanation (analysis): Why the illustration supports the point — the link between evidence and claim.
- Point
- Evidence
- Expand/Explain
- Link back to thesis
In Anglo-American academic writing, the topic sentence typically comes first. Sub-arguments, evidence, and elaboration follow. The final sentence often links back to or reinforces the paragraph's main idea.
Reference chains (using it, they, this development, the policy) connect sentences to what came before. Connectors (however, furthermore, as a result) signal logical relationships between sentences.
Paragraph Quality Markers
One Main Idea
Each paragraph develops exactly one central point — discipline of focus
Internal Coherence
Every sentence connects to the topic sentence — no wandering off-topic
Transition Link
The final sentence prepares the reader for the next paragraph's topic
Teacher Tip
“Give students a scrambled paragraph — the topic sentence and 4-5 supporting sentences in random order. Ask them to sequence them logically. The reasoning required to restore the original sequence makes the cohesion and logic of paragraph structure immediately visible. Far more effective than definition-based instruction.”
Frequently Asked Questions
Does the topic-sentence-first rule always apply?
In academic and business writing, yes — near universally. In literary and creative writing, the topic sentence may be deferred for effect. Teach students to distinguish contexts and match the appropriate convention.
How long should an academic paragraph be?
5-10 sentences is a reasonable range. Fewer than 4 sentences usually isn't enough to fully develop an idea. More than 12 often means the paragraph contains more than one main idea and needs splitting.
Is paragraph structure the same in all writing genres?
No — news writing often uses very short paragraphs (1-3 sentences) for online readability. Business reports use medium paragraphs. Academic writing uses longer, fully developed paragraphs. Always teach genre conventions alongside structural principles.
