Rhetorical Differences in Research Article Discussion Sections of High- and Low-Impact Articles in the Field of Chemical Engineering

Abstract

This study aims to delineate the rhetorical organization of research article (RA) discussion sections in an engineering discipline and explore the variations that distinguish discussion sections of high-impact and low-impact RAs. Research questions: What is the rhetorical organization of RA discussions in chemical engineering? What are the similarities and differences in the use of rhetorical moves and steps in RA discussions of high-impact and low-impact articles? Literature review: Some studies have been conducted using Swales’ move analysis with regard to the identification and textual comparisons of RA discussion sections. However, it remains to be determined whether RA discussions of the high- and low-impact articles within a single discipline display the variation in rhetorical patterns. Research methodology: A total of 40 RA discussions published between 2005 and 2015 were chosen based on five-year journal impact factor and citations of the articles in which they were published. Swales’ move analysis was used to compare rhetorical moves and steps in both sets of RA discussions. Results and discussion: The study identified the rhetorical organization of RA discussions in the field of chemical engineering. The findings indicate that discussion sections of high-impact articles tend to make use of the “comment on results” move. Explanations of the similarities and differences in the employment of moves and steps are provided. Implications of the findings are discussed.
