Abstract
The article propose the concern about the limitations that the university student population presents in reading comprehension and written production,
develops the proposal that each discipline is a particular culture with its object of study, its linguistic codes, its way of structuring thought and making proposals. Urges the teaching population of each career to take responsibility for providing the theoretical methodological tools necessary to learn the content of the subject, their respective literacy (learning to read and write) and the development of a critical discourse. proposes that the rhetoric provides theoretical bases and possible methods in the art of writing and understanding texts, from the classical Greek approaches, then going through linguistic studies of language and the Bajtinian notion of the different discursive genres, as well as modern linguistics with the
employment and understanding of discourse.
