Siegfried Englemann just died. For me he was a great man because he tried to tell the truth. My impression of the Education Establishment is that it rarely tries to tell the truth. 

Trying to dramatize this perspective, I thought of the fascinating story related in the Spielberg movie 1941. To hide the aircraft factories in California, set designers and carpenters went to work building an entire city directly above the factories.

The people in this photo are real but everything else is a prop. In my view, K-12 is like that. There's one disingenuous theory and method after another.

Article explains this unique bit of history AND the parallel with education.
