Assess students' ability to apply systemic-functional linguistic concepts to evaluate cohesion and information structure in academic research abstracts. Students should identify cohesion devices (reference, substitution, ellipsis, conjunction, lexical cohesion), analyze theme–rheme and given/new patterns, evaluate how these choices shape information flow and reader comprehension, and propose concise revisions to improve clarity and coherence. Scope: analysis of one short abstract (150–300 words) with textual evidence and recommended edits.
