Metadiscourse in Applied Linguistics and Chemistry Research Article Introductions

Abstract

This study examined disciplinary rhetoric in research articles, focusing on different traditions in structuring text discourses from a metadiscourse-move analytic approach. The corpus consisted of 72 research article Introductions (RAIs): 36 in applied linguistics and 36 in chemistry. Swales’ CARS model (1990, 2004) and Hyland’s interpersonal model of metadiscourse (2005) were used as analytical frameworks for move and metadiscourse analyses, respectively. Both frequency and functional analyses showed that there were considerable differences between the 2 disciplines in terms of how the writers used metadiscourse in the RAIs and how the metadiscourse markers were mapped to fulfill the rhetorical purposes of Introduction moves. Such discrepancies reflect the susceptibility of metadiscursive features to the sociorhetorical cultures conditioned by the discipline to which the writers belong. Findings have implications for teaching novices, especially nonnative speakers of English, to write research articles and help them create a convincing research space and make appropriate use of metadiscourse.
