I just attended the USNH Academic Technology Institute in Conway, NH.
Among many other things, there was talk of ADA Accessibility. One of the participants mentioned the Us Department of Education Office for Civil Rights Dear Colleague letter of May 26, 2011 and the attached FAQs.
As the use of emerging technologies in the classroom increases, schools at all levels must ensure equal access to the educational benefits and opportunities afforded by the technology and equal treatment in the use of the technology for all students, including students with disabilities.
I strongly urge you to take a look at this letter and the related FAQs!
