I just got some new Universal Design for Learning (UDL) materials that may interest you.
The first is this UDL brochure from the Region 5/7 AT committee. It's a good overview of UDL with information coming from CAST.
The second is a document that covers UDL and Direct Instruction from NCAC.
The third is a Powerpoint presentation (in PDF format) on UDL provided by the Region 5/6 AT committee.
