- Inclusion in education refers to the extent to which students with disabilities access and participate in regular classrooms, which can range from full inclusion to partial inclusion based on individual needs. - Differentiating instruction means creating multiple paths for students with different abilities, styles, and interests to learn and demonstrate understanding. This can be done through content, process, and product. - Universal design for learning (UDL) aims to make curriculum accessible to all students by providing multiple means of engagement, representation, and action and expression based on students' readiness, interests, and learning profiles. UDL and differentiated instruction are connected in making education accessible and effective for diverse learners.
