Issue - what specifically are you looking at? - evaluating measures
Significance - why are you looking at this?
Outline the organization of the paper: first section(s) - discuss key areas of the literature and authors and evaluate what they've done on the topic. Second section - compare measures. Third section (discussion) - What was learned from doing the comparison. Fourth section (conclusion) - How should what you've learned affect how people do things (either in practice or in policy)
I hope this helps,
This is also typically my favorite format for a lot of my essays. Not only does it make it easier on you to write the paper in a way that doesn't confuse yourself, it's also easy for the reader(s) to follow the information you're throwing at them.
Especially on this sort of subject, Colin's layout will do you a lot of good. As long as you have the evidence and the explanations/justifications to back it up, you need not worry about meeting any sort of length quota, and it'd be easier for your professor/teacher to pick apart your essay. An unstressed teacher is the best teacher!
