Understanding by Design is a framework for curriculum design that is oriented toward developing student understanding and focuses on "Big Ideas" in content areas. It has the potential to help educators unpack standards and help students develop deep conceptual understanding. However, challenges include giving educators time to implement it and making it a long-term initiative that involves all stakeholders. Moving forward, it could be improved by addressing differentiation for both high-ability and special needs learners to ensure high-quality learning for all students.
