There are some great resources out there. Florida has 5 regional centers providing support to districts (training, technical assistance, equipment loan), as well as creating print and web resources such as their "ENT" booklet. Here is their description:
"Exploring New Territories" (ENT) is a free resource from the Florida Diagnostic & Learning Resources System (FDLRS). The ENT booklet provides a comprehensive overview of technology for students with disabilities, including assistive technology, instructional technology, universal design for learning, accessible instructional materials, and virtual/online learning environments. Teachers and therapist will find a wealth of information, resources, and classroom activities to use."
The digital version is available at http://www.fdlrs.com/docs/ent2010web.pdf
