A Corpus-based Analysis of Stance in the Japanese Medical Students’ Essays The aim of this paper is to analyze essays written by Japanese medical students with regard to the epistemic comments, or stance, by means of corpus-based quantitative and qualitative analysis. More specifically, this paper underlines the importance of developing student genre awareness regarding rhetorical skills so that they can carry out the communicative requirements found in academic settings such as medical writing in the future. It is generally accepted that a major problem for academic essay writing in EFL is to convey statements with an appropriate degree of doubt or certainty. Such evaluative comments are crucial in academic writing, although novice writers often find it difficult to distinguish opinion from fact and to deal with expressing evaluative assertions in acceptable and persuasive ways (Hyland & Milton 1997). Many studies have also shown that direct and unqualified writing is more typical in EFL writing than with native speakers (Skelton 1988, Bloor and Bloor 1991). For instance, Japanese medical students are unlikely to use modifiers as epistemic modals, verbs, adjectives and adverbs, and are more likely to employ direct statements, which often leads to a misunderstanding of the writers’ commitment to fact. This paper will discuss the results of contrastive corpus data of students’ essays and Medcorpus, which is comprised of scientific articles in medicine, and explore how familiarizing students with patterns of epistemic expressions can be beneficial in raising student genre awareness.
