VCE General Achievement Test key terms

A single sentence that states the main claim an essay will defend. It usually appears near the start and guides every paragraph that follows, so readers know the writer's position before evidence is presented.

The opening sentence of a body paragraph that names the one idea the paragraph will develop. It links back to the thesis and signals to the reader what the following sentences are proving or explaining.

The way sentences and paragraphs are joined so a piece of writing reads as one continuous whole. It is achieved through linking words, repeated key terms, pronoun reference and logical ordering of ideas.

Words and phrases such as however, therefore, in contrast or firstly that show how one sentence relates to the next. They act as signposts, making the logic of an argument easy to follow.

The readers a piece of writing is aimed at. Their assumed knowledge, values and expectations shape choices about vocabulary, tone, length and how much explanation or evidence is needed.

The reason a text is written, such as to persuade, inform, entertain or reflect. Naming the purpose helps a writer decide on structure, evidence and language choices throughout the piece.

The level of formality in language, ranging from casual conversation to formal academic prose. Register is adjusted to suit the audience, purpose and context of a text.

The attitude a writer conveys towards the subject, revealed through word choice, sentence length and imagery. Tone might be ironic, urgent, sympathetic or detached, and it colours how readers receive the message.

The associations or emotional overtones a word carries beyond its literal meaning. Choosing 'slender' rather than 'thin', for example, signals approval, so connotations are powerful tools in persuasive writing.

The literal, dictionary meaning of a word, stripped of emotional associations. Distinguishing denotation from connotation helps a writer notice how word choice can slant a supposedly neutral statement.

A deliberate language strategy used to influence a reader's view, such as rhetorical questions, appeals to emotion, expert testimony or statistics. Writers combine several techniques to build a convincing case.

A question asked for effect rather than to obtain an answer. It invites readers to agree with an implied response, making them feel involved in the argument being built.

Citing a qualified expert or reputable organisation to support a claim. It strengthens an argument when the source is genuinely relevant and unbiased, but weakens it when the expertise is unrelated.

Word choice deliberately packed with strong positive or negative feeling, such as 'reckless' or 'heroic'. It steers readers towards a judgement without offering reasons for that judgement.

Facts, examples, statistics or quotations used to support a claim. Strong evidence is relevant, accurate and drawn from a credible source, and it must be explained rather than simply dropped into a paragraph.

A reasoned case in which a claim is supported by evidence and explanation. An argument differs from an opinion because it anticipates objections and shows why the conclusion should be accepted.

A point that opposes the writer's position, raised and then answered. Including one shows fairness and breadth of thought, and rebutting it can make the writer's own case more persuasive.

The response that weakens or dismisses a counter-argument. An effective rebuttal shows the opposing point is based on faulty evidence, a misunderstanding or an assumption that does not hold.

A flaw in reasoning that makes an argument unreliable, such as attacking a person instead of their point or assuming two events are causally linked. Spotting fallacies is a core analytical skill.

A broad statement applied to a whole group on the basis of limited cases. Useful generalisations are qualified with words like 'often' or 'many'; sweeping ones ignore exceptions and weaken reasoning.

Restating another writer's idea in your own words while keeping the meaning intact. Paraphrasing demonstrates understanding and must still acknowledge the original source to avoid plagiarism.

Presenting someone else's words or ideas as your own without acknowledgement. It includes copying text, borrowing an argument without citation and submitting another person's work as your own.

A shortened form such as 'don't' or 'it's', formed by omitting letters and replacing them with an apostrophe. Contractions suit informal writing but are usually avoided in formal essays.

A punctuation mark used to show either omitted letters in a contraction or possession, as in 'the student's essay'. Its placement changes meaning, so plural possession needs care.

Marks such as commas, semicolons and full stops that organise written language into meaningful units. Correct punctuation controls rhythm and prevents ambiguity in complex sentences.

A word that joins words, phrases or clauses, such as 'and', 'because' or 'although'. Conjunctions express relationships between ideas and help writers build complex, layered sentences.

A comparison of two or more quantities showing how many times one contains another. Ratios can be written with a colon, as a fraction or in words, and are simplified like fractions.

A statement that two ratios are equal, allowing an unknown quantity to be found. Solving proportions by cross-multiplying is a standard method for scaling recipes, maps and models.

A number expressed as a fraction of one hundred. Percentages make comparisons between different-sized groups easy, and percentage change is calculated relative to the original amount.

A ratio comparing quantities with different units, such as kilometres per hour or dollars per kilogram. Rates describe how one quantity changes with respect to another.

The arithmetic average, found by adding all values and dividing by how many there are. The mean is affected by extreme values, so it is often reported alongside the median.

The middle value when data are arranged in order. With an even number of values it is the average of the two middle ones, and unlike the mean it is not distorted by outliers.

A data value that lies far from the rest of the set. Outliers can pull the mean noticeably while leaving the median almost unchanged, so they should be identified before averages are interpreted.

A number between zero and one expressing how likely an event is. It can be estimated from equally likely outcomes, from relative frequencies or from a given model.

The complete set of all possible outcomes of a random experiment, such as the six faces of a die. Listing the sample space helps ensure no outcome is overlooked when calculating probabilities.

The number of times an event occurs divided by the total number of trials. With many trials it tends to approach the theoretical probability, which is why it is used to estimate real-world risk.

A statement accepted as true without proof in order to build an argument or model. Identifying assumptions is essential, because a conclusion is only as reliable as the premises it rests on.

A stated reason or piece of information offered in support of a conclusion. In reasoning questions, separating premises from the conclusion clarifies what is actually being claimed.

The claim that an argument is trying to establish. It is what the premises are meant to support, and it may be stated explicitly or left for the reader to infer.

A conclusion drawn from available evidence rather than stated directly. A sound inference follows necessarily or with high probability from the given information; a weak one goes beyond it.

A statistical relationship in which two variables tend to change together. Correlation alone does not establish causation, since a third factor may influence both variables.

A relationship in which one factor genuinely produces a change in another. Establishing causation requires more than observed association, such as controlled comparison or a plausible mechanism.
