Linguistic discourse analysis of lexico-grammatical features of moves in the research abstracts of medical students in a Ghanaian university

Abstract

Writing a quality research abstract is crucial for a scholarly report. An abstract should be information and lexically dense, formal, and have a professional tone. This requires precision, objectivity, logicality, technicality, and comprehensiveness. However, writing a good-quality research abstract is a hurdle for novice and inexperienced undergraduate students who study English as a Second Language (ESL), that is English language learners worldwide. This article interrogates the research abstracts written by undergraduate medical students who also studied English Language at the University of Health and Allied Sciences (UHAS) in Ho, Ghana. A qualitative-quantitative approach, guided by Hyland’s (2000, 2004) five-move model, was used to analyze the lexico-grammatical features in the rhetorical moves of the research abstracts written by these students. A corpus of 23 extracts representing a quota of sample tenses, hedges, boosters, and nominalization were analyzed. The data were coded manually and presented as frequency counts and percentages in tables and graphically. The results revealed that rhetorical moves in the research abstracts written by undergraduate medical students of UHAS in Ho, Ghana were replete with simple past, simple present, and perfect tenses, and lexico-grammatical devices such as hedges, boosters, and nominalization to a greater or lesser extent. The study concludes that the research abstracts written by undergraduate medical students of UHAS follow Hyland’s (2002, 2004) five rhetorical move model, and are constituted by specific lexico-grammatical features. The pedagogical implications are discussed, and suggestions for future research are provided.
