What if traditional ‘language’ courses came with a disclaimer?

Disclaimer:

The course you are enrolling in is a traditional language course. Almost nothing we do this semester will contribute to language acquisition. This course is focused on language as an artefact, and so we will be discussing grammar, analysing syntax, memorising morphology, rote-learning vocabulary associations with our L1, and translating sentences back and forth as a form of practice, with no attention to the communicative meaning or purpose of those sentences (if they had any).

We will definitely not be using language to communicate, develop any communicative ability, learn to read effectively, to understand or communicate in our target language. In fact, less than 5% of what we do in the course will be useful if that is your hope, and the ability of the other 95% of our explicit teaching to contribute to you acquiring the language is slim to none.

The memorised explicit knowledge you can expect to gain in this course will primarily be useful in taking tests on explicit knowledge, taking further courses of the same kind, or vaguely pursuing linguistics somewhere down the track. Otherwise it will be quickly forgotten.
