The rhetorical organization of research article discussion sections: An investigation into genre evolution in applied linguistics

The present study aimed to investigate the evolution of the rhetorical structure of research article discussions in three prestigious journals covering the two chronological periods of 1980-1989 (group A) and 2005-2010 (group B). It also studied changes in the application of the two most frequently used verb tenses − the simple present tense and the simple past tense − over the two time periods. Overall, 115 published articles were selected from the aforementioned journals. Move analysis was accomplished through application of Dudley-Evans' (1994) model on the datasets. Findings indicated that despite the overall consistency in utilizing the nine-move organization, there emerged rather considerable differences in the frequency of (Un)expected outcome and Explanation moves. A reduction in the frequency of (Un)expected outcome in group B indicated that present-day writers announce results with more caution to win the acquiescence of reviewers and readers. On the other hand, a rise in explanations revealed a growing concern for including more arguments in order to follow the analytical nature of the discussion section. The results also demonstrated a shift from the simple present tense toward the simple past tense, which marks a shift from generalization to specificity.
