In a discursive piece you are expected to discuss a given topic and present an argument related to it.
There are two basic types of discursive essay. Firstly there are persuasive essays in which you can argue strongly either in favour of or against a given discussion.
Alternatively, there are argumentative essays. In these you look at a discussion topic in a balanced way.
There are many sources you can use to find information for your discursive essay. These include:
When looking in the library, focus on the non-fiction and reference sections. When searching online, always think carefully about key words.
Make sure you consider the reliability of all your sources. It is important you keep a note of where all your information comes from. This will allow you to check it again later and to complete your bibliography and footnotes.
