both The Mayo Clinic and a much smaller less-equipped local Clinic/Hospital (Olmsted Medial Center) have computers in every room (except OMC has no patient/visitor access computers (they have wifi though) including the ER department. I have seen in the Mayo Clinic ER (do to being more ER bays than computers) where i have seen multiable ER Staff (nurses/doctors) sitting at multiable computers as they all update the file of the same patient. In the hospital (Non-ER section) they have atleast 4 computers spread across each corridor and staff will use those to update patient files (some times updating multible patient files at the same time). Can't speak for everywhere just what I have locally, Both places didnt even switch from Windows XP until Windows 8 came out and they run 7 (I wonder why the skipped Vista)
1. What if the parents cannot afford the cost?
2. Giving every studet a iPad would cost the same thing as providing each teacher with (or access too) a supply of iPads so that every kid WOULD have one however unless it is needed for homework they would STAY on school property, They can be assigned to each student or just handed out like textbooks were. And is students needed to take their iPad home for doing homework the teacher would but it on a sign-out sheet and have it in the mobile lab (say 1 mobile lab-per teacher per class either or the school would be spending the same amount of money BUT also the rish is less that something can happen to them if they stay on school property.
and lastly, you can bypass the school filters as the filters on the iPad would only be in place whilst on school property when the kids take them home they could connect to their own wifi and download all the games or watch all the porn to their heart's content. The filters are done over Network Proxy not on physical devices (atleast thats what the IT guy in my middle school told me) not sure if there's a different practice in place for iPads.
1. When you work in a medicine and know how they're used in practice you'll understand how things work. Not all doctors/medical providers have tablets or laptops at all.
2. In middle/high school we almost always needed our books for homework, some classes more than other. Given that a student probably takes 5-7 classes at a time, the chances of needing their device is likely very high on a daily basis for homework. Especially if they're using collaborative practices or utilizing eBooks. Sign outs make no sense.
3. $250-275, isn't a ton of money per student relatively speaking. Also consider that the school won't necessarily need desktop computers anymore which will be cut down that portion of the technology budget.
4. The program's I have seen have the school pay for the device and the parents pay for the insurance if they so choose. I'm sure if the families cannot afford the insurance or replacement cost, accommodations are made i.e free coverage or subsidization. The insurance may even be paid for in subsidized areas.
5. There are programs out there to control usage and downloads, including some built in features in iOS. I've see a program that will lock students out of the Internet for test taking or lock their screens. I think this topic has been well considered with solutions beyond network restrictions.
