Teaching Children with Autism: An ABA Primer by Dr. Reg Reynolds, Psychologist. This second edition of "ABA: A Brief Introduction to Teaching Children with Autism," published in 2010, includs what I have learned about teaching children with autism in the intervening three years. It is an excellent place -- I believe the best place -- to start if you are a parent whose child has been diagnosed with autism, or if you are an instructor/therapist of children with autism.
