Tóm tắt	Comparative Visual Analysis is a qualitative research design that systematically examines and compares visual materials — photographs, videos, artworks, advertisements, or digital images — across two or more cases, groups, time points, or contexts. By applying a consistent analytical framework to multiple visual corpora, the approach reveals similarities, differences, and patterns that would remain invisible when studying a single set of images alone.	Comparative discourse analysis examines how language constructs meaning, identity, and power by systematically contrasting texts or speech acts drawn from at least two distinct contexts, groups, time periods, or institutions. By holding analytical categories constant across cases, it reveals how discursive patterns diverge or converge, producing insights that single-context discourse analysis cannot generate.
