Universal Design for Learning (UDL) is a framework to improve and optimize teaching and learning for all people based on scientific insights into how humans learn. UDL provides multiple means of representation, action and expression, and engagement. It involves presenting information in different ways, allowing for diverse ways for students to demonstrate what they know, and fostering motivation. Technologies such as text-to-speech, closed captioning, and assistive technologies support UDL principles. When implemented well through tools, resources and careful lesson planning, UDL can positively impact student learning outcomes.
