Everything you need to cite correctly — from the first in-text citation to the last reference entry. A 14-slide interactive crash course with a practice quiz included.
This is the full written version of an interactive, slide-by-slide lesson deck used in teaching. Everything covered in the deck is below — open the interactive version to work through it with live diagrams, worked examples and a practice quiz where included.
Everything you need to cite correctly — from the first in-text citation to the last reference entry. Built for your assignments. No textbooks required.
Using someone's idea without credit is plagiarism — even accidentally. A citation is your proof you know the difference between your thinking and someone else's. No citation = no defence.
Academic writing isn't a monologue — it's you positioning your ideas within an ongoing scholarly debate. Citations show you've been listening, and you know who said what first.
The "says who?" test: Imagine your examiner asking "says who?" after every claim you make. Citations are your answer. Without them, you're just asserting things into the void.
"Caffeine consumption has been associated with enhanced cognitive performance in controlled studies (Smith et al., 2021, p. 14)."
Any fact that came from a specific study, dataset, or report. Even if widely known within your field, if it has a source — cite it. E.g. "87% of Agile teams use Scrum" needs the State of Agile report.
Someone else's argument, model, or framework. Even if you're paraphrasing it — you're using their intellectual work. Presence theory (Witmer & Singer), Agile Manifesto, TAM model — all need citations.
Especially contested or field-specific definitions. "Presence is defined as..." is someone's definition — whose? Even for widely agreed terms, citing the first/key theorist shows depth and awareness.
Obviously. Any word-for-word text from a source requires quote marks + author + year + page number. Even a single distinctive phrase taken verbatim needs a page-level citation.
Surveys, questionnaires, measurement scales, or research instruments designed by others. The Presence Questionnaire, SUS, TAM scales — all have original authors who must be credited.
Yes — even your own previously published work. Reusing your own ideas without citing yourself is called self-plagiarism. If you published it elsewhere, treat it like any other source.
Over-citing clutters your writing and actually signals low confidence — it looks like you can't tell what's common knowledge and what isn't.
"The internet is widely used" — no citation needed. Any reasonably educated person already knows this.
"The sample had 24 participants split into 4 groups of 6" — this is your own arithmetic. No source needed.
Your interpretation, argument, and conclusions are your contribution. Don't undercut it by citing someone else — own it.
Things you observed, measured, or found in your own study. "Participants reported feeling dizzy" — this is your data.
Would a reasonable person in your field consider this general knowledge? If yes → no citation. If there's any doubt → cite it. When in doubt, cite.
A reference list entry with no matching in-text citation. You read it, but never cited it. Remove it — APA is not a bibliography.
An in-text citation (Brown, 2021) with no matching reference list entry. Always fatal — the reader can't find the source.
The idea matters more than the person who said it. You're reporting a finding, not engaging with a specific author's argument.
You're specifically engaging with who said something. You're introducing their argument, critiquing it, or contrasting it with another author's view.
⭐ APA 7 key change: Three or more authors → use et al. from the very FIRST citation. APA 6 made you write all names up to 5 authors first. That rule is gone.
"Presence is defined as the subjective experience of being in one place or environment, even when one is physically situated in another " (Witmer & Singer, 1998, p. 225).
Honest advice: Your examiner wants to see you synthesise ideas, not collect them. Use direct quotes only when the exact wording matters — definitions, key terms, pivotal statements. A paraphrase that cites correctly shows more skill.
The concept of presence is not simply about visual fidelity but rather about the degree to which the virtual environment responds to the actions of the participant. A high-fidelity environment that does not react to user input will produce lower presence than a lower-fidelity, richly interactive one. (p. 431)
The author + year introduce the quote (narrative style), then the page number appears in brackets after the final full stop — not before it. This is reversed from short quotes.

Two papers share first authors + year. APA says write enough names to distinguish them — then et al. Don't assume the first name is enough.
These footnote shorthand terms belong to Chicago/Oxford style. APA never uses them. Ever. Just repeat the full author–year citation each time.
If you only read the abstract, you only read part of the paper. Don't cite findings from sections you haven't read. Read the paper. Then cite it.
APA reference list = only sources cited in the text. Nothing extra. A bibliography includes background reading — APA doesn't. Remove anything you didn't cite.
Always search for a DOI before using a plain URL. DOIs are permanent — URLs rot. Always prefix: https://doi.org/ not dx.doi.org or just the number.

Use the first author's surname followed by et al. from the very first citation. This changed in APA 7 — APA 6 required listing all authors up to five on the first mention.
A reference list contains only the sources you actually cited in the text, and every in-text citation must have a matching entry. A bibliography can include background reading you consulted but never cited. APA uses a reference list.
APA 7 changed this from APA 6: use et al. from the very first citation for 3+ authors. APA 6 required all names up to 5 authors on first mention.
n.d. stands for "no date" — used when a source has no identifiable publication date. Common for some websites and unpublished works.
40 or more words = block quote. Format: new paragraph, indented, no quotation marks, citation after the full stop.
Two authors use an ampersand (&) inside brackets. When authors are part of the narrative sentence, use "and" — e.g., Brown and Jones (2021).
APA reference lists are always alphabetical by the first author's surname. Same-author entries are then sorted by year, oldest first.
Always use https://doi.org/ as the prefix. The older dx.doi.org format is no longer recommended, and a bare number is incomplete.
Article titles use sentence case: only the first word, proper nouns, and the first word after a colon are capitalised. Journal names stay in Title Case and are italicised.
An APA reference list ≠ bibliography. Only sources you actually cited go in the reference list. Remove anything uncited — it's not a "further reading" list.
