“…As far as the design of the study was concerned, the design of the study in hand was descriptive, quantitative, nonexperimental and corpus-based study in nature to analyze metadiscourse features. As far as the metadiscourse discourse classification was concerned, it is worth noting that since its advent, there has been proposed several models of metadiscourse classifications (see for example Crismore, 1989;Vande Kopple, 1985Hyland, 2005;Adel, 2006), However, for the purpose of the current study, the classification proposed by Hyland (20005) was exploited; due to the fact that it is not only the most up to date model, but also, the most well-defined, established and comprehensive model (Ghadyani& Tahririan, 2015). In his model, metadiscourse features are basically divided into main categories as interactive and interactional.…”
