Universal Design for Learning (UDL) is a framework for designing curriculum that provides access and removes barriers for all learners. UDL promotes using multiple means of representation, expression, and engagement to accommodate different learning styles. This is based on research showing there are three primary brain networks involved in recognition, strategic thinking, and affective engagement. UDL principles include providing options for perception, physical action, and engaging interests. Technology supports UDL through tools like electronic whiteboards, laptops, and software that enhance representation, participation, and motivation for diverse learners.
