요약	Opportunity to learn (OTL) analysis measures the degree to which students are actually taught the content on which they are assessed, and relates that exposure to their achievement. Rooted in Carroll's 1963 model of school learning and developed as both a research concept and a policy instrument by McDonnell (1995) and the international IEA assessments, it treats content coverage, instructional time, and the alignment between the enacted curriculum and the tested curriculum as measurable conditions of learning rather than properties of the learner.	Content analysis is a systematic research technique for reducing text, visual, or media material into coded categories so that patterns can be counted, compared, and interpreted. Formalised by Klaus Krippendorff in his widely cited methodology textbook (latest edition 2018), the method sits at the boundary of qualitative and quantitative inquiry: it imposes structured, replicable coding on inherently meaning-laden material.
