What I usually do is an expository essay, just a really simple and conventional essay format. Basically just discuss the prompt whilst also keeping in mind that you don't push towards any specific agenda.
For each of the body paragraphs, I use this format:
- General topic sentence introducing a key concept you have derived from the prompt.
- 2 or 3 sentences explaining and building on this topic sentence. What I like to do for identity and belonging is that I say something like: 'Familial experiences can contribute to the formation of one's individual identity in the sense that..' and then I counteract this with something like this: 'With the lack of genuine and meaningful familial experiences, individuals may...' Notice the words 'may' and 'can' have been used - you need to make sure you are not absolute in your expression and present ideas only.
- Then introduce a real-life example, explain it using quotes and then relate it to the concepts of identity and belonging, and most importantly, the prompt. Discussion of the real-life example goes for around 5 or 6 sentences. Good examples to use - virtual online identity and also the Stolen Generations.
- Link the ideas of the prompt and the ideas presented in the real-life example to an explicit example from the text. Use quotes and interpretations to explain this textual evidence. Do it in the same way you did the discussion on the real-life example. So this is the text responsey part of the expository - but be careful and do not overdo it with evidence and discussion of the text.
- Finish off the paragraph with any concluding statements and a linking sentence if you want.
Of course you're going have your own individual style and way of doing the context piece, so this is just the way I tackle it. Hope it helps.
