I would say I followed a type of formula in my context and text writing as well, and still managed to get the high marks in them (better than my language analysis, in fact!).
My body paragraphs for text response always tried to incorporate a structure:
1. Topic sentence - outlining the main idea of the paragraph --> basically so that lazy examiners who just read topic sentences would know where I was going, and could be sure each paragraph was well focused.
2. Where suitable, an explanation of the point or further detail to make it sound better or at least clearer (not required if the topic sentence was concise enough).
3. A detailed example of where in the text my point was illustrated.
4. An explanation of how this example specifically illustrated the point. At the end, I sometimes mentioned other examples but in less detail (kind of to show how my point was 'compounded' by other instances).
5. A concluding sentence, either tying back to the topic (of the entire essay) or to tie together the ideas in a paragraph where I had heavily developed an idea from its original premise (eg. In my exam, I had a paragraph about "Powerlessness and power being a closely linked cycle" (in Richard III) which developed into the notion of "an overwhelming hunger for power stemming from a sense of powerlessness". So my concluding sentence of the paragraph tied the two ideas together.)
While not formulaic to the extent of being repetitive, it was an attempt to cover these common bases in a rather "TEEL" way. In my view, the most important idea of the essay was to write complex ideas in a simple, concise and clear way - if part of this involves a formula to get all the ideas out, I find it acceptable. The real "innovation" in my essays came from the points I chose and the actual "discussion" - ie. it relied on me knowing the texts really well and just having a clean and effective way to execute the essay. (This is also the reason I am reluctant to tutor texts I have not done myself).
Context was along these lines:
1. Topic sentence
2. Elaboration on the topic sentence - a quote from a philosopher where appropriate.
3. Example from text.
4. Explanation of the example --> talking about how it applies to specific characters, but trying to keep the ideas as abstract as possible (eg. In this scene, Joe experiences the subjectivity of memory, as strong emotions of anxiety and anger warp his reconstruction of the event.)
5. Concluding sentence bringing together the ideas of the paragraph, but keeping it abstract.
Hope this is of some help.
