Based in neuroscience, UDL is an approach to curriculum and instructional design that seeks to eliminate barriers to learning for all students. UDL presumes a diversity of learners in classrooms and all students are offered increased opportunities to access, participate, and progress in the general education curriculum. Curriculum designers use the UDL framework to structure and organize strategies for learner access, interpretation and processing, and application of content knowledge and skills. UDL also emphasizes additional aspects of learning, such as processing information and building deeper comprehension of content; utilizing executive functioning, organizational skills, and progress monitoring abilities; engaging in the learning environment; and defining self-assessment and self-reflection strategies.
