This book chapter describes an approach to designing curriculum, instruction, and assessments in which teachers plan backwards from what they want students to understand and be able to do and engage students actively in meaningful learning experiences involving inquiry and application of skills and knowledge in authentic contexts. This overview highlights the value of student input, regular checks for understanding, and performance assessments guided by clear criteria for quality work.
