You only need "one" PC per school of PI's to create the SD card
installations. This comes with some development tools installed.
Each child can have their own SD card and so you don't need any network
to develop.
You can program on the PI rather than having to use a PC as with other
many embedded solutions.
Its cheap enough and low power enough so that you can stick it in in a
project and not worry about the cost.
Take a look the web site:-
http://www.raspberrypi.org/
and see what folks are doing.....

P.S. mine is still sat in front of the TV as a media server. However I
think I will get another to use as small file server.

As I have said several times, if you want to learn how a computer really
works, buy a non-working Unibus PDP11 (nto an 11/24, 11/84, 11/94, etc
,one of the TTL-baed ones), a PDP8/e or an HP9830 and learn to fix it. By
the time it's working you will know just how a CPU executes instructions.
If you are prepeared to use a microprocessor, then get a BBC micro. I've
yet to se a better educational machine. Seriously.
But I do wonder jhsut who the Rpi is aimed at. Given that you need a PC
and its peripherals (keyboard, mouse, monitor) to use the Rpi, I wonder
if it wouldn't be simpler jsut to install a free C compiler on said PC,
at least to learn programming.
-tony There are, IMHO, 3 thigns wrong with the Rpi. The
hardwre, the software,
adn the docuemtnion.
I think my main problem with it is that I'm tainted by
nostalgia, and what
I really wish it was is a backplane system with separate cards for ROM,
RAM, CPU, I/O, video etc. :-) Much more fun to mess around with, put into
a cool-looking chassis, use to teach kids about how a computer works etc.
