There are so many academic and social benefits to providing AT devices for students with physical disabilities. Without their implementation, students and teachers are both at a huge disadvantage academically. First, watch the movie How Assistive Technology Enables Dreams and fully explore the "DO-IT" webpage.
Then, take the role of a special educator who has a student with a physical limitation in your classroom who you know would benefit from assistive technology. Using research-based information to support your position, choose one AT device that is geared toward people with physical disabilities and justify a request for funding to purchase this equipment. Make sure to include the cost, any required training, and how it will impact the student short and long term.
