Assess students' ability to apply discourse analysis to academic research articles by identifying and labeling cohesive devices (reference, substitution, ellipsis, conjunction, lexical ties), evaluating coherence (local/global thematic progression, relevance, information flow), and mapping argument structure (claims, evidence, warrants, counterarguments, rhetorical moves). Tasks include annotating excerpts, constructing argument maps, diagnosing coherence breaks, and proposing targeted revisions for improvement; scope limited to peer-reviewed article excerpts.
