This document compares and contrasts differentiated instruction and universal design for learning. It discusses that differentiated instruction is a teaching theory that adapts instruction to individual student needs, while universal design for learning is a framework for developing adaptable curricula based on principles of representation, engagement, and expression. Both approaches recognize classroom diversity and value equity and excellence, but differentiated instruction focuses on the instructional process while universal design for learning is a curriculum framework. The document argues that combining differentiated instruction and universal design for learning can lead to success for all students.
