The document discusses Understanding by Design (UbD), an instructional design model. UbD involves designing curriculum backwards with three stages: 1) Identifying desired results such as goals, standards, and understandings; 2) Determining acceptable evidence of student learning; and 3) Planning learning experiences and instruction. The model emphasizes designing curriculum to promote student understanding rather than simple content coverage. UbD helps educators unpack standards, ensure students truly understand concepts, and design courses emphasizing understanding over coverage.
