There is a video of him speaking candidly to a group of graduate students where he claims success in public education. If I can find it again I need to post it.
Why would he be so happy? They started in the inner city schools in the 70s and worked to implement what is now considered Common Core education. They began testing new kinds of ideas with kids whose parents would not kick up a fuss like suburban school parents always do.
They started with situation ethics and sex education and then worked to tuck that same type of emphasis into the other classes like math and science. If you ever wonder why the lessons seem so screwy that is why.
The result is not to enable a kid to think.
The ultimate goal is to turn our kids brains into tools for the state.
It should really be called Commie Core.
