Avoiding plagiarism and citing sources correctly
Most plagiarism in student work isn't a deliberate attempt to cheat — it's a citation habit gone wrong: a paraphrase that stayed too close to the original wording, a source read weeks ago and half-remembered as an "original" thought, or a citation that simply got lost while reorganising a document. That doesn't make it less serious academically, which is exactly why building good habits early matters.
What counts as plagiarism
- Direct copying without quotation marks and a citation — the most obvious form, but far from the only one.
- Close paraphrasing — changing a few words while keeping the original's sentence structure and flow. This still needs a citation, and if it's too close to the source's specific phrasing, it may still count as plagiarism even with one.
- Uncited ideas — using someone else's argument, framework, or specific insight without crediting them, even if you've rewritten every word in your own language. Citation covers ideas, not just exact text.
- Self-plagiarism — reusing substantial parts of your own previously submitted work without disclosure. Many institutions treat this as a genuine academic integrity issue, not just a formatting quirk, so check your specific policy if this might apply to you.
- Uncredited use of AI-generated text — increasingly covered explicitly by university policies; check your institution's specific rules, since they vary and are still evolving.
How to paraphrase properly
A genuine paraphrase means understanding the source's idea well enough to explain it without looking at the original text at all — read the passage, close it, and write the idea in your own words from memory, then check back against the source only to verify accuracy, not to borrow phrasing. If you find yourself needing the source open in front of you to paraphrase it, that's usually a sign the result will end up too close to the original wording.
When to quote directly instead
Direct quotes (in quotation marks, with a citation including a page number) make sense when the exact wording matters — a precise legal or technical definition, a particularly well-put argument you want to engage with directly, or language you intend to critique. Outside of those cases, paraphrasing in your own words, woven into your own argument, is usually stronger academic writing than a page full of quotes strung together.
Citation styles
Different fields favour different citation styles, and the "correct" one is whatever your course, journal, or supervisor asks for — check before you start, since retrofitting an entire document to a different style late is painful.
- APA — common in the social sciences and psychology.
- IEEE — common in engineering and computer science, using numbered in-text citations.
- ACM — common in computer science, particularly for conference papers.
- MLA — common in the humanities.
- Chicago/Harvard — widely used across various fields, sometimes with author-date and sometimes with footnote variants.
A reference manager makes switching between these close to painless, which is one more reason to set one up early.
Why is this important?
Beyond the academic integrity consequences, which can be serious, citation is also how the academic community gives credit for ideas and lets readers verify and build on claims themselves. A well-cited piece of work isn't just "safe" — it's more trustworthy and more useful to anyone reading it, including your future self trying to remember where a claim came from.
Tips
- Cite as you write, not afterward. Trying to reconstruct which claim came from which source once a document is finished is slow and error-prone — and is exactly how citations get lost.
- When in doubt about whether something needs a citation, cite it. Over-citing an idea that turned out to be common knowledge costs you almost nothing; missing a citation you needed can cost you a great deal.
- Run your own work through your institution's plagiarism-checking tool (e.g. Turnitin) before submitting, if you have access — it catches accidental issues (a forgotten citation, a paraphrase that stayed too close) before a marker does.
- Know your specific institution's policy on AI tool use for writing and research, and follow it precisely — policies vary significantly between courses and institutions, and "I didn't realise that counted" rarely helps after the fact.
