概要	Document-based curriculum analysis is a qualitative research method that systematically examines written curriculum artifacts — textbooks, syllabi, national standards, policy documents, scope-and-sequence guides, and lesson frameworks — to reveal intended learning goals, ideological assumptions, gaps, and alignment between policy and practice. It treats curriculum documents as primary data rather than supplementary material, applying structured content and interpretive analysis techniques to answer questions about what knowledge is valued, how it is sequenced, and whose perspectives are represented.	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.
