A Makerbot In Every Classroom 152
Daniel_Stuckey writes "At the start of this year, President Obama nicely summed up the grandiose promise of 3D printing — or rather, the hype surrounding it. In his State of the Union address the president suggested the fledgling technology could save manufacturing by ushering in a second industrial revolution. That shout-out inspired a spate of buzzkill blog posts pointing out — rightly enough — that despite its potential, 3D printing is still in its infancy. It's not the panacea for the struggling economy we want it to be, at least not yet. Apparently the naysayers weren't enough to kill the 3D-printing dream, because, with support from the federal government, MakerBot announced its initiative to put a 3D printer in every school in America. The tech startup and the administration are betting big that teaching kids 3D printing is teaching them the skills they'll need as tomorrow's engineers, designers, and inventors."
Caveat: Makerbot no longer produces open hardware, and they are pushing proprietary Autodesk software and educational materials as part of the free 3D printer. Makerbot also launched a call for open models of math manipulatives on Thingiverse (you might remember them from elementary school) so that teachers have something useful to print immediately.

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.

Re:Makerbot Not For Kids (Score:4, Insightful)
Here is one area where a 3D printer can encourage students to learn a skill. Suppose that you were reverse engineering some object with many pieces Each student would have to measure and design a piece in the CAD software. Now, most students do not understand why good measurement is necessary, or why they need to make an effort to draw the object exactly, or how many measurements are really needed. So each student draws and the pieces are put together in the software, and adjustments are made because the pieces are not going to fit exactly. Eventually the group of students gets something that fits together in the software and prints. Inevitably one or two pieces are not going to fit together in the physical prototype, debugging will have to happen, and much learning will go on.
The problem is that such a process is long, there are not many grades involved, and students who are not motivated and curios tend not to benefit very much. There has to be a reason to have a tool in the classroom, and a understanding of how it is going to be used. otherwise it will, like the laser printer, be used to print shoes.
