If a teacher has not previously heard of UDL, then this site is for them. Universal Design for Learning essentially captures the idea that by making information accessible for all students, it actually helps every student learn–not just the ones who might need to access information in a non-traditional way to understand it. This website can help educate teachers on the principle of UDL and how to implement strategies in their classroom.
