Abstract
This study aims to compare the Introduction section of a number of medical research articles written by non-native speakers of English (Iranian) and English native speakers in terms of their rhetorical structures. The articles published in ISI-indexed journals have been investigated using the models presented by Nwogu and Halliday. The models are related to Moves/Sub-moves and grammatical metaphors, respectively. Using statistical tests such as chi-square tests for goodness of fit and Mann-Whitney U tests, the authors have found that the Iranians used fewer Moves/Sub-moves and grammatical metaphors compared to native speakers. Awareness of this academic writing practice may contribute to pave the ground for Iranian researchers to publish their articles in world-known journals. Keywords: genre, writing, research articles, SFL, ESP, ESL, grammatical metaphors.
Highlights
Over the past few years, genre-based approaches have become the focal point of interest for many scholars undertaking studies in a number of disciplines including Applied Linguistics, Linguistics, Philosophy and Literature (Hyland, 2007)
The third research question related to the grammatical metaphors was answered in the second phase of the study, Systemic Functional Linguistics (SFL)
Analysis of chi-square was run to answer the first research question of the study comparing the IrISI and English ISI Journals (EISI) articles in terms of the frequencies of Moves used in their Introduction section
Summary
Over the past few years, genre-based approaches have become the focal point of interest for many scholars undertaking studies in a number of disciplines including Applied Linguistics, Linguistics, Philosophy and Literature (Hyland, 2007). The willingness of graduate and undergraduate students to learn English is for the purpose of taking part in higher education in universities and institutes across the world where English is the medium of instruction (Bruce, 2008). Genre-based approaches can play pivotal roles in encouraging students to learn English and writing required by world-known universities (Cheng et al, 2010). It is noteworthy to say that genre-based approaches used for the teaching of writing can pave the way for graduate and post graduate students who will be or are experts in different disciplines to publish their research findings in Calidoscópio internationally-known journals (Swales, 2004).
