Great project! I spent last year in India and other Southeast Asia areas
tracking the low-cost Android phone/tablets trickling in from China
under various names.

On a related note, Google's own approach to this problem is to focus on
Chromebooks. Here's a story/promo for their work in Malaysia:

You need to balance your need for an initial "low-cost" solution versus
the costs down the road of user frustration, broken device support, etc.
Keeping Android tablets upgraded, functioning, malware free, etc is a
decent effort. I would definitely look into Chromebooks, and also
consider how much of the learning you may want your students to do
should actually involve a keyboard/laptop type form-factor versus just a
touch screen.

Most low-cost Chinese tablets I have owned lasted about four to six
months. These were in the $50-80 USD price range. That is the biggest
compromise you make with the price is build quality. All the specs will
be the same, but the thing will just stop working due to a bad solder,
cheap screen, shorted power plug or some dust/humidity related condition.

To contrast that, a Nexus 7 2012 edition I have has easily lasted nearly
two years, and will likely last a few more, especially since I have it
in a nice case. You can get these now for $149-199 USD.

I can't give much more advice beyond what I have, but in my own efforts
to thing about providing cheap+secure tablets to activists and others, I
have decided that I would rather focus on Nexus hardware, produced by
ASUS, that costs a bit more up front, but last longer and is very reliable.

Best of luck!
