A home computer in 1980 could do way more than any cheap piece of plastic one of these printers will ever produce. Those kids would be better off with VIC-20's and Sinclairs, and they would be a lot cheaper.
I have to agree with this one.
My youngest daughter is now in middle school, 7th grade. Her school did not get a Makerbot donated to them, but they did purchase one for the computer lab. I have issue with this, but not because they have a 3D printer. It's because they spend money like this constantly (this isn't the only purchase they've made that I have issue with) and yet they do not even have the proper course materials available for students.
She has a total of one textbook. And it's of the dead tree variety. I don't believe that they need to make the immediate move to digital, though I think it would be beneficial. I have issue with the fact that they just do not have textbooks for all but one of her classes. So if she is having issues with the material that her teacher feels the need to send home with her, there is nothing for her to turn to for assistance.
Thankfully her mother and I are capable of helping her, but what about the students that don't have the family resources available to them for help? We also help tutor one of my daughter's friends, as her parents are either not capable or not willing to make themselves available to do so, but we cannot take on every student that needs help. We do not have that kind of time.
For students in her age range, this is nothing more than a toy. And a waste of money.
