I was recently asked, "Why are you giving the teachers choice of a laptop? Why not just go all in with one device?" My answer, simply stated, is that homogenization of any tool is never a good idea in a context that is intended to foster creativity.
The same argument is underway with the Common Core. Many fear that we are homogenizing educational standards and limiting opportunity for creativity, hacking and boundless exploration. That explains the viral popularity of Ethan Young, a Tennessee student who, at a school board meeting, provided an eloquent breakdown of what the Common Core really is and how it is affecting teachers. His points are valid, but the same points have been raised for years in education only to fall upon the deaf ears of bureaucrats.
