I do wish folks would stop repeating this canard, or at least back it up:
"Schools are no longer clustered according to geography. Instead, they elect to join networks organized around an instructional philosophy or particular area of expertise.'
First the networks were crated in spped dating forums and information fairs.
Even back in 2007 some networks were the cool kids in the lunchroom and others were the left overs, left behind and forced to network by some other affiliation- like from the same Leadership Academy class- or the ability to form an ESO ( not an option for all schools, BTW) or mere chance...
Fast forward 5 years as things morph, in the dark, and tell me now, please, just how many networks are organized around pedagogy or expertise or ANYTHING!
