The document discusses localization and contextualization in teaching. It defines localization as adapting the curriculum to local conditions and relating content and teaching methods to the local environment. Contextualization means developing skills and knowledge in students by presenting new concepts in meaningful, real-life contexts. The K-12 curriculum allows schools to localize and contextualize lessons based on their educational and social contexts. Localization maximizes available materials and anchors teaching to learners' lives. It also encourages using local problems and strategies to address issues. Localization and contextualization can enrich all learning areas while respecting diversity.
