What is the best way to structure an essay question on an unseen poem?

Aside from the obvious introduction and conclusion, the way that's worked the best for me is a focus on four basic elements of the poem (or any text being studied), with a paragraph on each: form, structure, language, tone. The form of the poem is the type of poem being looked at- whether the poem is a ballad, sonnet, dramatic monologue, or free verse among others. Certain forms are typically associated with certain tropes and themes. The ability to identify the form being used can allow struggling students to grasp the message of certain poems without even understanding the language, as they are already familiar with the common themes of this form. Similarly, the structure of the poem is the way it is laid out, associated with techniques such as line and stanza length, syllable count, line breaks and end stops and juxtaposition- the location of lines, words and punctuation within the poem. Language comes with certain techniques such as metaphor, imagery and personification (as well as the depth of vocabulary), and the tone refers to the way the poet or speaker may be feeling emotionally while writing the poem. This encompasses techniques such as pacing and the harshness or softness of word sounds (sibilance, clipped consonantal sounds among others). Within the paragraphs themselves, I would advise them to use PEE paragraphs roughly (point, evidence, explanation), and within that the ICE technique (identify, connotation, explanation). This rubric provides students with a general outline to structure their essays on, overall and within paragraphs. The 4 different paragraph themes are generic and there is blatant overlap, but they allow for a comprehensive essay structure that ticks all the boxes of the poem and the mark scheme itself. Through this rubric, upon identifying techniques students are able to group them into certain sections, and comment on them more effectively than if the techniques were randomly interspersed throughout the essay. It is a structure I learned and used in GCSE, and continue to use in university in my English course today.
