Sometimes students feel that they have done a lot of research but this is not reflected in their grades for writing an essay. There are many reasons for this, which this article attempts to explain.
First of all there is so much information on the Internet that it can be confusing. It is not enough to simply copy what someone has said and use this as an authoritative statement in your own work. Just because it has been said by someone doesn’t make it absolutely true. You need to look for the facts behind the statement, is it backed up with solid evidence? If not, perhaps your "authority" isn’t a good one.
When you look up information remember to keep a record of the author, date, title and name of publication and the date you retrieved the information if you got it online. If you can’t give this information then you shouldn’t use a quotation from that source. You need to check and double-check ‘facts’ found online.
In academic writing you have to produce rather a lot of evidence with which to persuade your readers that your work is of merit. This is why thorough research and detailed bibliographies are necessary. It isn’t enough to have a theory and to write about it, if there is not a substantial body of evidence to support your brilliant theory, it will not be well-received by your tutor. You have to argue your point and be able to refute the counter-arguments through quotations from other respected academics in your field.
Lastly, remember not to use "I" or "you" but the impersonal third person "one" in academic writing. You are writing for a formal audience so your language should be formal.
