Thanks a lot, Rusty and David, for your answers.

Of course, Krashem is one of the greats. I think his theory that distinguish acquisition from learning is in the root of communicative approach.

Thanks a lot for your translations, Rusty. I gather that communicative approach is exactly the term I was looking for. But the other one you say is more in the field of pragmatics that in the nuance of the enfoque nocio-funcional. It's not socio-funcional but nocio-funcional what I meant. I'll try to find something similar.

Thanks a lot.
