That’s a very different subject to anything I’ve studied so take this with a pinch of salt, and use what you find helpful.
Have a look at the marking rubric and make sure you get the ‘free marks’ ie there will normally be 20 or so put aside for format/clarity of expression and proper referencing. If the tutor wants it written in Comic Sans, 14 point, double spaced, do it even if you think it’s stupid. It sounds really basic but it’s amazing how many students miss out on the free marks.
Sign post – eg state what a paragraph is about and remind the tutor what you’ve already done: ‘having undertaken a holistic assessment of the care of patient x, this paper now considers…’ or something like that. You’ll know from your reading what the conventions are in your field. Introductions get written last once you know what you’ve done. Mine took a general format of: Broad statement about the subject. Introduction of controversies. This paper [general statement of tack the paper is taking] Firstly, it considers blah; next, it turns to blah, considering particularly blah. It integrates the insights from blah1 and blah2 and offers a critical analysis of blah. Finally it concludes with blah, proposing blah (normally ideas for future work). That kind of thing anyway, so they know from the start what you’re aiming at - make it easy for them to give you the marks!
Possibly dependent on subject: for us top marks were reserved for original thought and proposing new ideas. If there are limitations in existing methods, mention them – but I'm not sure about that: with patient care, possibly they don’t want students to start making up new and ignoring established procedures....
I reference heavily and would normally average at least one reference per hundred words, but you can stack them, and should, if there if a lot of evidence. “Numerous studies attest to the importance of y (eg: reference 1, year; reference 2, year; reference 3, year.)”
Critical evaluation can include things that go well as well as things that go badly.
Use the referencing software, endnote, or whatever you have. If you’re not familiar with it already, it really helps to get a handle on it early on and not wait until starting dissertation.
Give yourself enough time, but don’t give yourself too much, otherwise you can start second guessing yourself. I write about 800-900 words a day, but final draft standard and fully referenced. Other people write twice as fast but then do a second edit – different approaches work for different people.
You should receive lots of feedback on your first assignment. If you have an opportunity to discuss with your tutor make sure you do.
Hope it goes well.
