I found this article interesting that was published on the autism.com site (you can read the full article here about learning styles: http://www.autism.com/understanding_learning). Here's the second half of the article:
"Based on my experience as well as those of my colleagues, it appears that autistic individuals are more likely to rely on only one style of learning. By observing the person, one may be able to determine his/her primary style of learning. For example, if an autistic child enjoys looking at books (e.g., picture books), watching television (with or without sound), and tends to look carefully at people and objects, then he/she may be a visual learner. If an autistic child talks excessively, enjoys people talking to him/her, and prefers listening to the radio or music, then he/she may be an auditory learner. And if an autistic child is constantly taking things apart, opening and closing drawers, and pushing buttons, this may indicate that the child is a kinesthetic or 'hands-on' learner.
Once a person's learning style is determined, then relying on this modality to teach can greatly increase the likelihood that the person will learn. If one is not sure which learning style a child has or is teaching to a group with different learning styles, then the best way to teach could be to use all three styles together. For example, when teaching the concept 'jello,' one can display a package and bowl of jello (visual); describe its features such as its color, texture, and use (auditory); and then let the person touch and taste it (kinesthetic).
One common problem evidenced by autistic children is running around the classroom and not listening to the teacher. This child may not be an auditory learner; and thus, he/she is not attending to the teacher's words. If the child is a kinesthetic learner, the teacher may choose to place his/her hands on the child's shoulders and then guide the student back to his/her chair, or go to the chair and move it towards the student. If the child learns visually, the teacher may need to show the child his/her chair or hand them a picture of the chair and gesture for the child to sit down.
Teaching to the learning style of the student may make an impact on whether or not the child can attend to and process the information which is presented. This, in turn, can affect the child's performance in school as well as his/her behavior. Therefore, it is important that educators assess for learning style as soon as an autistic child enters the school system and that they adapt their teaching styles in rapport with the strengths of the student. This will ensure that the autistic child has the greatest chance for success in school."
