Learning about poetry (how to read it, write it, and appreciate it) is an integral part of teaching students about all forms of writing. A poem is not just a place to present a student’s grammatical knowledge (in fact, it is often the space to subvert it!). Poetry, more than any other form of writing, trains students to take into account the style of language. This close looking and listening is crucial to writing well in any manner. It would be hard to say that any outstanding essay does not involve meticulous word choice or the ability to persuade a reader through sheer aesthetic prowess. Poetry teaches students how to do this.
