My HS junior daughter, a easy child, has volunteered to work as a 1-1 aide for a 3-year-old with Pervasive Developmental Disorder (PDD)-not otherwise specified at a sports program. She will be supervised by a "coach" who is an adult professional. She wants to teach elementary school and is trying to figure out if Special Education is something she wants to do. I think that she would be awesome at it. Anyway, I am looking for a book or some articles to give her to read to familiarize herself with Pervasive Developmental Disorder (PDD)-not otherwise specified and ABA, which the program will be using. She knows Aspies and at least one profoundly autistic child, but noone who is middle of the spectrum, which is where I have been led to believe the kids in this group will be. They will have training but she is a child who learns best by reading things over and over. Thanks for any input.
