I thought I'd keep all the English stuff in this thread, haha. I'm gonna go create a thread for my course now (English Language A)! How dare you compare English Language to Media, I'm wanting to study it at university, hehe!
Well I studied CLA last year for AS and really enjoyed it. The questions in June 2011 and January 2012 allowed me to structure the essay around the theories, which is probably quite a good basis. I suppose there's two ways.
The first way is to start with the theories and link the features to it. For example, if you were talking about the role of the caregiver then you could start by saying it's important. Link it to Skinner and talk about reinforcement, then mention something like overgeneralisation which suggests language is indeed learnt because mistakes are made.
On the other hand, it may be an issue with the LAD... then you could go on to talk about Chomsky and the nativist theory, linking it to other features such as virtuous errors, etc.
The second way is to go through the features, and link it to the theories. For example, if you were talking about the role of the caregiver then you could say.. "overgeneralisations would suggest the caregiver is indeed important.. this was backed up by Skinner".. etc.. etc.
Both are equally good ways because you're getting the same information down, although I'd probably lean towards the former because it seems a tad more structured.
