This is the handbook to accompany the text, Understanding by Design, by McTighe and Wiggins.
Understanding by Design, or UbD, is an increasingly popular tool for educational planning focused on "teaching for understanding" The emphasis of UbD is on "backward design", the practice of looking at the outcomes in order to design curriculum units, performance assessments, and classroom instruction. The UbD framework was designed by nationally recognized educators Grant Wiggins and Jay McTighe, and published by the Association for Supervision and Curriculum Development.
According to Wiggins, "The potential of UbD for curricular improvement has struck a chord in American education. Over 250,000 educators own the book. Over 30,000 Handbooks are in use. More than 150 University education classes use the book as a text."
