The document discusses localization and contextualization in education. Localization refers to relating learning content to local information and materials from the learner's community. Contextualization is the process of relating the curriculum to a particular setting or situation to make competencies relevant and meaningful. The document provides examples of localization and contextualization in subjects like Mother Tongue. It emphasizes that localization allows the use of different learning materials in different areas of the country so the curriculum can be delivered based on local standards. The REACT strategy for contextual learning structures curricula around experiencing, applying, cooperating, transferring, and reacting concepts in meaningful contexts.
