Understanding by Design (UbD) is a backwards design curriculum model created by Grant Wiggins and Jay McTighe. It is a 3 stage process that begins with identifying desired learning outcomes and establishing big ideas and essential questions. It then focuses on developing assessments to check for understanding before planning learning experiences and instruction. The goal is to align assessments and learning activities to curriculum standards while promoting higher-order thinking skills. UbD aims to clarify expectations for students and allow for differentiation of instruction based on learner needs.
