Ninety research article Introduction sections (i.e., 15 from each discipline of applied linguistics, sociology, psychology, biology, agriculture, and geology) were examined. The study was conducted with reference to the onion model of discourse analysis developed by Humphrey and Economou (2015), and the data were coded by MAXQDA10. Results pointed to a general underlying pattern that moved from descriptive and taxonomic reports to more challenging genres like persuasion and critique, regardless of the disciplines. Findings, however, indicated that individual disciplines manifested their own systematic regularities in terms of rhetorical conventions of writing. Besides, the process of knowledge-making was reflected and reinforced through lexicogrammatical and appraisal resources. The study has implications both for teaching and materials development.}, keywords = {Critical Discourse Analysis (CDA),Research Article Introduction Sections,Onion Model}, url = {https://rals.scu.ac.ir/article_14181.html}, eprint = {https://rals.scu.ac.ir/article_14181_89afd908dc476587147f73f7953a1183.pdf} }
