CAST originated UDL and gives the clearest short introduction. The placement also creates a useful bridge to accessible media, assessment and participation across the rest of the DEI vertical.

Summary, mindmap and highlights
UDL starts with a practical observation: learner variability is ordinary. A course is easier to enter when the design anticipates differences in prior knowledge, language, attention, disability, confidence and available technology.
CAST organises the framework around multiple means of engagement, representation, and action and expression. Engagement concerns purpose and sustained involvement. Representation concerns how information can be perceived and understood. Action and expression concerns how learners practise, communicate and show what they know.
The learning goal and quality standard remain clear while the route gains useful flexibility. A diagram can accompany a dense explanation, a transcript can accompany audio, and an assessment can offer several accessible media when each option measures the same outcome.
The video is an older overview. CAST's current Guidelines 3.0 add stronger attention to identity, bias and collective learning. They should be the working reference for course redesign.
