Hi Eric. Thanks for the post. As you know, shared reading is one of the context we've been using to support students in learning to use graphic symbols to initiate and respond. In our earlier work with girls with a diagnosis of Rett syndrome and their moms, we found that shared reading offered an opportunity for repetition with variety. In other words, moms could read and retread the same book over a number of days (repetition) but the ways they interacted and the things their girls responded to varied just a little each time. As a result, the girls, who had little to know symbolic communication prior to the introduction of repeated, shared storybook reading with their moms, experienced really nice communication outcomes. We've continued to investigate shared reading and are currently doing a study to investigate the added benefits of print referencing strategies that draw the child's attention to the printed words. We're using beginning level books like those on http://tarheelreader.org so that the distinction between the illustration and the print is clear. We don't have results just yet, but have 5 parent-child pairs who should finish by the end of June. I will try to share results here when we get them
