[Assess students' ability to apply discourse analysis to short research-article introduction excerpts by identifying and labeling sentence- and paragraph-level cohesive devices (reference, lexical cohesion, conjunction, substitution, ellipsis) and mapping rhetorical move structure (e.g., Swales' CARS: establishing territory, niche, occupying niche). Require annotated examples, concise justifications with textual evidence, and a brief explanation of how cohesion supports each rhetorical move's communicative function.]
