Paul Hamilton has created a new website that focuses on Universal Design for Learning (UDL). To quote his intro:
"This site hosts information about Universal Design for Learning, and shares free and low-cost digital tools
that facilitate a UDL approach to learning, as well as tools to support learners with access challenges."
You will find information on UDL, a section on access as well as sections on representation, expression and engagement (the cornerposts of UDL), and handouts.
This website is a work in progress, so be sure to return periodically to look for new ideas!
