Elizabeth Meckstroth is credited for this widely appreciated quote:
If we were TV sets, some of us would only get five channels. Others are wired for cable (the general population) and some of us (the gifted) are hooked up to a satellite dish. That makes these gifted children capable of making connections that others don’t even know exist! Teaching those types of voracious minds in a regular classroom without enhancement is like feeding an elephant one blade of grass at time. You’ll starve them.
There’s nothing else to say.
