We already use analytic tools like this in education, but they do a poor job preparing us for the complexity of human discourse.
For example, we teach students about the 8 parts of speech. This provides handles that they (and their teachers) can use in the future to improve their writing and reading comprehension (e.g. “did you notice how many vivid adjectives he used in that chapter” or “you should avoid the passive voice with your verbs”). But this framework is primarily focused on the structure of language, not the elements of thought, reasoning, and communication. This probably explains why it’s rarely used past middle/high school.
We also teach students about different sentence types: declarative (statement), interrogative (question), imperative (command), and exclamative (exclamation). This is less useful than the parts of speech framework. Categorizing sentences by end punctuation isn’t very illuminating. And of course, it completely misses (by definition) anything that is not a sentence (i.e. single words, phrases, paragraphs, etc.)
Among other things, I hope that this new framework will provide a more useful tool for teachers and students. Discourse blocks or knowledge elements are better units for analyzing discourse, because they’re defined not by their grammatical form, but by their role in conveying meaning and advancing ideas.
