The document summarizes the 2010 Secondary Education Curriculum in the Philippines which uses the Understanding by Design (UbD) framework. UbD is a backwards design approach that focuses on developing student understanding through essential questions and performance-based assessments. The three key stages of UbD are: 1) identifying desired learning outcomes, 2) developing assessments to measure student understanding, and 3) planning lessons and activities.
