Thanks for the suggestion. I own a BBB so I'll have a look at it (the
parabola stuff), only thing that could be a potential problem is the price.
People know of the Pi so if I suggest an "expensive version of the Pi" (if
you know what I am saying) I must have a good story. Free software is usually
lower on the list than budget for schools....But I can try.
I do spend some time talking about the FSF / GNU and the virtues of using
free software to the kids. It will be just a matter of time before one finds
out the Pi isn't exactly fsf friendly, but I think it is a step in the right
direction. At least I talked the school out of buying 30 ipads...
By the way , the kids absolutely LOVE working with the Pi and Scratch, which
is the first programming thing we are looking at. They think it is pretty
cool to work with such a small device.
Teaching free software one step at a time, better then nothing I suppose....
