Dividing up the middle

[Andrew Patterson]

I've just started teaching a Cambridge Proficiency class and either next week or the week after, I'm going to teach writing essays. At lower levels, say up to FCE, there aren't too many problems dividing up a text:

For polemic essays, it would be:
Introduction -> Major points -> Minor points -> Conclusion.

For discursive essays in would be:
Introduction -> Points for -> Points against -> Conclusion.

Even there, the difficult step is often dividing up the middle as most students have an idea of what an introduction and conclusion should contain.

With much longer essays, dividing up the middle in a logical way becomes overwhelmingly the most difficult task.

I'm using Objectives proficiency, which for a 300-350 word essay suggests:
Para 1: Introduction
Para 2 Generalising
Para 3 Specifying
Para 4 Raising an argument
Para 5 Giving one side
Para 6 Giving the other side
Para 7 Conclusion.

My question is, would it be worth including another paragraph to summarise before the conclusion, or would this be seen as unnecessary repetition?
I might add that I can see from this layout that even longer essays could further split paras 5 and 6 into i) major points and ii) supporting points.
