I think the fact that your venture goes along with a well-established product like Kurzweil makes it very feasible but I have some apprehension about the idea of teaching reading on an iPhone. I don’t really enjoy trying to read on a tiny screen, so I don’t think a student who struggles with reading would either. IPads are used far more in education. Is there already an app for them? I also don’t see many iPhones among my students until about the 6th or 7th grade, so I don’t know how effective this would be for younger learners.
