The document discusses the backward design process for curriculum planning proposed by Grant Wiggins and Jay McTighe. It involves three stages: 1) identifying the desired results in terms of enduring understandings and essential questions; 2) determining acceptable evidence of student understanding through performance tasks and assessments; and 3) planning learning experiences and instruction to help students achieve the targeted understandings. The backward design process is presented as a framework to design or redesign any curriculum to make student understanding more likely.
