The four main types of academic writing are descriptive, analytical, persuasive and critical. Each of these types of writing has specific language features and purposes.
In many academic texts you will need to use more than one type. For example, in an empirical thesis:
The simplest type of academic writing is descriptive. Its purpose is to provide facts or information. An example would be a summary of an article or a report of the results of an experiment.
The kinds of instructions for a purely descriptive assignment include: identify, report, record, summarise and define.
It’s rare for a university-level text to be purely descriptive. Most academic writing is also analytical. Analytical writing includes descriptive writing, but you also re-organise the facts and information you describe into categories, groups, parts, types or relationships.
Sometimes, these categories or relationships are already part of the discipline, sometimes you will create them specifically for your text. For example, if you’re comparing two theories, you might break your comparison into several parts, for example: how each theory deals with social context, how each theory deals with language learning, and how each theory can be used in practice.
The kinds of instructions for an analytical assignment include: analyse, compare, contrast, relate, examine.
To make your writing more analytical:
In most academic writing, you are required to go at least one step further than analytical writing, to persuasive writing. Persuasive writing has all the features of analytical writing (that is, information plus re-organising the information), with the addition of your own point of view. Most essays are persuasive, and there is a persuasive element in at least the discussion and conclusion of a research article.
Points of view in academic writing can include an argument, a recommendation, interpretation of findings or evaluation of the work of others. In persuasive writing, each claim you make needs to be supported by some evidence, for example a reference to research findings or published sources.
The kinds of instructions for a persuasive assignment include: argue, evaluate, discuss, take a position.
To help reach your own point of view on the facts or ideas:
To develop your argument:
To present your argument, make sure:
Critical writing is common for research, postgraduate and advanced undergraduate writing. It has all the features of persuasive writing, with the added feature of at least one other point of view. While persuasive writing requires you to have your own point of view on an issue or topic, critical writing requires you to consider at least two points of view, including your own.
For example, you may explain a researcher's interpretation or argument and then evaluate the merits of the argument, or give your own alternative interpretation.
Examples of critical writing assignments include a critique of a journal article, or a literature review that identifies the strengths and weaknesses of existing research. The kinds of instructions for critical writing include: critique, debate, disagree, evaluate.
You need to:
Critical writing requires strong writing skills. You need to thoroughly understand the topic and the issues. You need to develop an essay structure and paragraph structure that allows you to analyse different interpretations and develop your own argument, supported by evidence.
