Divergent thinking is done by a mind that is turned ‘on’ and engaged in the constant questioning of reality, instead of passively ‘dumbed down’ by rote solutions force-fed through memorization and shallow learning. Divergent thinking creates fantastical worlds such as those imagined by the likes of Nikola Tesla, Buckminster Fuller, Beethoven, Einstein, Pythagorus, Leonardo Da Vinci, Marina Abramovic, and similar personalities.
This article is so misinformed as to be laughable.
To begin with: why does the author use the 1960s as his baseline? Many would consider the "teach them how to think, not what to think" revolution of the 60s as something of a disaster (e.g., "the new math," denigrating history as "learning names and dates", grammar....). Before then, rather excellent educational results were obtained by "rote solutions force-fed through memorization and shallow learning."
Entire generations, for example, learned a common cultural basis from the McGuffey Readers and the like. Among other things, that common cultural grounding was the means by which the great American melting pot assimilated a huge number of immigrants from disparate cultures.
And to hold out the likes of Einstein and Tesla as exemplars of how everybody should think is ridiculous. Those guys were many sigmas out on the tails of the normal distribution -- the vast majority of people are simply incapable of the leaps of intellect those guys could make.
What's more, if you look at Common Core math, you'll see that its basic approach is .... to teach kids
how to think about math, rather than teaching them "rote solutions." It fails, precisely because it's doing what this yutz wants it to do.
There's plenty to dislike about Common Core. There's also plenty to dislike about articles like this one.
