 A couple of the things that we've piloted, we've got a couple of digital textbooks and iPads on classes that we're piloting and from that particular company, we can get back student log in, log out, and ask some metrics of student activity and so that kind of stands in contrast to what we've been unable to get at anything external, the little suite of academic apps that our own folks wrote internally back in the summer of 2008 before the App Store was even open, we could get hits and so on for, but that's been a challenge kind of all along the way. I think just in terms of faculty, app use and entrance or maybe development through this whole process, it seems to me, and I mentioned this yesterday in the presentation, I think we're seeing patterns where our faculty are entering in what we would call administrative tasks, so an attendance app, a class roster, pushing out class assignment due dates, the calendar, everything from the course documents being online, and then we continue to try to move faculty along to pick that first classroom app to tinker with and pilot with and get enough tech support to help it to be successful soon anyway, and then including some out of classroom activity, either a precast podcast on the front end or the blogs or some other activity on the back end. Is this a concern? It is, in fact we're doing an educational research study, two different studies, one with our anesthesiology department that is requiring the residents to have iPhones, providing lecture capture, using a response ware for assessments, providing a mobile app that they have to learn 15 different procedures, so an app that teaches them these 15 different procedures that they can use as a reference tool, and we're going to track their performance on their board scores and those things, and then the other thing that we're doing, because we are an academic health sciences center, we're also doing a breast cancer app for patients, and we're doing an educational study on that to see how providing a patient that gets diagnosed with breast cancer, an iPad with this application on there that takes them from the diagnosis through their treatment, so we're going to capture data on that, and the iPad provides some of that data, and some of the manufacturers of different apps now also include different data tracking, very granular to tell exactly what part of the app or what part of the content they're spending the most time in, and so you can track some of that data, that's become a more popular feature.
