I'm looking for research into how technology, specifically iPad's, are assisting students with autism academically with their numeracy? Are there any large studies being carried out or are they small pilot projects with a few students?
As far as I am aware, there are only small studies available at this point in time. While the iPad's have been shown effective to enhance student's learning, the results are usually moderate.
Here is a couple of papers that you may find useful:
