What an absolute lie.
I'm an old guy, and despite having gone to a Military Academy for High School and Junior college, and multiple degrees in engineering. science and business administration from decades ago, even then, Out of hundreds of teachers, I had maybe 10 that taught me how to think, not what to think.
I can't imagine, that, given the state of the educational system these days, one would be lucky to encounter 2 or 3 teachers / professors in 20 -25 years of education who tried to teach their students how to think, rather than what to think.
“”And we teach them how to think, not what to think.””
Neither is true. Kids are currently taught NOT to think, just to parrot leftist and woke idiocy.
