Trying to present a fuller picture of language

I would say one of my biggest issues is trying to address the complexities of language in the understandably reductive tendencies of the teaching environment.
This is especially difficult in language teaching, since language is the intersection and confluence of different aspects of the human condition. It is not just about "the facts," although many students would like to think that by memorizing vocabulary and verb charts that "is" language. Nor is it enunciating words with an impeccable "native" accent. Nor is it navigating the cultural-pragmatic nuances of formality or "best" style.
Some students are still not very aware of how language shapes their attitudes and how it interacts and constructs social, political, economic, etc. "realities." I would really like to have time to address some of these issues, but can't. With all that complexity, how do I organize a 50 minute class that touches on the before-mentioned issues, while still meeting the institutional standards and addressing my own students' individual needs for language instruction?
