The short answer
Each body paragraph should open with one sentence that states the paragraph's single main idea—then everything else supports it.
What a topic sentence does
A topic sentence tells the examiner exactly what the paragraph will argue. It supports Coherence and Cohesion because the reader can follow your essay by reading the first sentence of each paragraph.

Weak vs strong topic sentences
A weak topic sentence announces the topic without a position; a strong one states a claim the paragraph will prove.
Weak → Strong
Weak: There are many things to say about technology in education. Strong: Technology improves education because it gives every student access to the same high-quality materials.
Mistakes to avoid
Avoid topic sentences that contain two ideas, copy the question wording, or include examples. Examples belong in the support, not the opening sentence.
- One idea per paragraph.
- Do not copy the question.
- No examples in the topic sentence.
- Match the paragraph that follows.
