We even lack the tech to run governmental sites in a stable and secure way. Forget about making this kind of technological movement worthy for the kids.
These will be highly restricted tablets - even not working outside of classrooms -, and with highly censored Internet. We have a tendency to restrict any sites against Islamic creationism so most of any pro-evolution or even scientific evolution ones will be restricted. I believe they will put the kids on a "white-listed" restriction zone.
Other than these points, we lack a decent educational system. Every government has been trying to circumvent the system according to their views and change curriculum, exam and admission ways annually. And there are too many children lacking the basic thinking and reading abilities. So these tablets won't make any good to them.

Even governments have been circumventing how long and "how" the education system is. This year AKP legislated an education system of 4+4+4 which means, well I have no fucking idea! But as much as I've heard it would make possible 4 year old kids to be admitted for elementary school which will have "optional" Quran and "Prophet Muhammad" lessons and women to be continue education without attending the last 4 years.

In the light of these information, I again don't believe this bold move means anything for the children. It's just a pr and social engineering move.
