This document provides an overview of Understanding by Design (UbD), also known as Backward Design. UbD is a framework for designing curriculum and teaching units that begins with the end goal in mind - what the student should know and be able to do. The framework consists of three stages: 1) Identifying desired results through standards and essential questions; 2) Determining acceptable evidence of learning through performance tasks and other assessments; and 3) Planning learning experiences and instruction. Key aspects of UbD include aligning goals, assessments and activities, using essential questions to engage students, and allowing flexibility in instructional strategies to meet goals.
