Uso de movidas retóricas y patrones léxico-gramaticales en artículos de investigación en espa？ol: Implicancias para la ense？anza de la escritura científica

in this paper, we propose a new method for the description of rhetorical structures and their corresponding linguistic features in research articles in spanish. the method is based on a critical review of different approaches focusing on this phenomenon. to this effect, we labelled a 162-research-article corpus using rhetorical moves. the corpus is representative of chilean scientific production between 2000 and 2008. we applied statistical techniques to over the 11,000 records to account for the prototypical rhetorical moves and describe the lexico-grammatical patterns associated to them in this type of specialist texts. the results of the study demonstrate the operation of particular 'prototypical' rhetorical moves in such texts as well as the lexico-grammatical patterns which formalize the former. the research done provides valuable empirical evidence both for those aiming at the analysis of scientific discourse and those focusing on the teaching and learning of scientific writing.
