The document discusses contextualization in the Philippine K-12 curriculum framework. It defines contextualization as relating curriculum to students' socio-cultural backgrounds and local communities. The framework emphasizes contextualizing subjects like Araling Panlipunan, Music and Art to reflect students' diverse cultures and regions. It also allows for contextualizing Math and Science lessons through localization, using local examples, materials and practices. Teachers are encouraged to weave national competencies with students' community realities and knowledges to create meaningful lessons.
