UDL draws upon neuroscience and educational research to remove barriers and maximize learning for all students through a flexible curriculum. There are three primary principles of UDL:
Provide multiple means of engagement: The variety of ways learners are engaged or motivated to learn.
Provide multiple means of representation: The variety of ways that learners perceive and comprehend content that is shared with them.
Provide multiple means of action and expression: The variety of ways that learners can navigate the learning experience and share what they know.
