My 10 yr old has Aspergers. One of his favorite things to do is play video games... it's the action/excitement/etc. I have made use of educational computer programs/games since he was 6. He learned much faster, and retained the information to a higher degree when using these tools, as opposed to say, flashcards and repetitive learning techniques. He is currently finishing 5th grade, and is close to the top of his class academically.
Without these tools, based on personal experience with him early on, I doubt he'd be at this level without the computer games/programs we've used.
