Corpus e géneros textuais nas práticas de divulgação de ciência ou as novas hierarquias na construção do conhecimento

This paper, as result from the research project Scientific Literacy Promotion, funded by the Calouste Gulbenkian Foundation, shows, in a first moment, the heterogeneity of the textual formats that participate in the dissemination of science, widespread by the media in Portugal, starting from the analysis of the relations between corpus, genres and texts. In a second moment, the textual support, in particular the evolution from print to digital, led to a discussion of the linguistic and textual implications of this development, as well as the implications of the new hierarchies of knowledge construction.
