In my opinion, this goes to far. They've taken out the factor of learning how to set up a server, how the port forwarding works, and everything actually educational you can get out of Minecraft. What they're really putting in schools is computers with custom maps installed to help you "learn". Sure, I'd be fun to play video games in school, but no thank you, this isn't learning.
I read the website but I'm still horribly confused. It sounds more like a joke than an actual learning device. Unless you are able to learn spelling and math in the world of Minecraft while constantly fighting the urge to build a giant **** out of sand, I don't see exactly what education could possibly be attained by playing Minecraft. Apparently the teachers can post assignments and such, but the example given is to chop down some trees. It seems more like a mod to help you learn to play Minecraft than anything else.
what do you do if creepers blow up your virtual school house? do we get extra credit for rebuilding it? will the virtual school go on lock down? if i bring a bow and arrow to virtual school and shoot everyone will i get virtually arrested? im taking this too far. xD
