Universal Design Instruction (UDI) aims to maximize learning for all students by accounting for differences in student backgrounds, abilities, and needs. UDI follows three principles - representation, expression, and engagement - to provide multiple ways for students to acquire knowledge, demonstrate what they have learned, and maintain interest. By reducing barriers in the curriculum, UDI creates a more inclusive learning environment that supports a wider range of learners through thoughtful consideration of goals, materials, teaching methods, and assessments.
