A didatização do discurso da ciência na mídia eletrônica

Abstract

This thesis is linked to the research program developed at LABLER which stands for Laboratório de Pesquisa e Ensino de Leitura e Redação, a laboratory of research and reading and writing teaching and to the research group Language as social practice as it integrates the development of the CNPq Project (301962/2007- 3) Critical genre analysis with focus on science popularization articles (MOTTAROTH, 2007). As part of the project mentioned before, this thesis has as objective to examine the discursive practices involved in the midiatization of scientific knowledge from a linguistic and discursive point of view with attention to the way the content of a scientific article is resignified in science popularization news in a special way by the use of linguistic strategies of reformulation. The work is founded on the Critical Genre Analysis using as sources the Socio Rhetorical Perspective and the Critical Discourse Analysis and searches subsidies in the approach of the Pedagogical Model, by Bernstein (1996) to comprehend the science popularization process, according to Motta-Roth (2009a, b, c, d; 2010a, b) and Motta-Roth; Marcuzzo (2010) formulations. The research corpus is compounded by 60 science popularization news, published in the electronic media in the sites of BBC News International, Scientific American, Nature and ABC Science from 2004 to 2008. The contextual analysis of interpretative basis was made considering information gathered on the sites and their owners via hyperlinks. In the textual analysis, of interpretative basis, the reformulation cases were raised according to the adequacy of the taxonomy proposed by Hyland (2007) for the discursive functions of reformulation. The distribution and function of reformulation strategies in science popularization news had as basis the representation of the rhetorical organization of science popularization news genre elaborated by Motta-Roth and Lovato (2009, p. 246). The results point to the use of reformulation strategies as an essential aspect to recontextualization of scientific knowledge for allowing knowledge midiatization. This fulfillment is guaranteed by the strategies of meaning expansion and delimitation which allow that the writer guides the reader in the news reading process, characterizing it as an activity of mutual collaboration.
