Critical thinking is what will make your essay stand out.It shows the marker that you are not simply repeating the arguments that have been fed to you throughout your studies, but actually engaging with theories in an academic manner.
Being descriptive is fine if you are looking to scrape a pass, but for a higher grade you need to show that you are able to leverage critical reasoning in your dealing with academic materials.
Once you have identified a few solid articles, you should (a) go through their bibliographies and take note of who they are citing, as these articles will likely be of value for your own research; and (b) check on Google Scholar to see who has cited them.
To do this, simply input the name of the article in the search bar and hit enter.
If you are still not a hundred percent sure, it is usually a good idea to skip to the conclusion – this usually contains a detailed summary of the study, which will help determine whether you should read the article as a whole.
You don’t want to waste time reading through and endless number of articles simply to find that they aren’t actually relevant.
