Educational jurisdictions around the world now include critical thinking in guidelines for curriculum and assessment.Political and business leaders endorse its importance.
: “The other day, when I was down town on 16th Street, a clock caught my eye. This suggested that I had an engagement at 124th Street, at one o'clock. If not, I might lose more than twenty minutes in looking for one.
I reasoned that as it had taken me an hour to come down on a surface car, I should probably be twenty minutes late if I returned the same way. Then I thought of the elevated, and I saw there was such a line within two blocks. If it were several blocks above or below the street I was on, I should lose time instead of gaining it.
It suggested a flagpole when I first saw it; its color, shape, and gilded ball agreed with this idea, and these reasons seemed to justify me in this belief. The pole was nearly horizontal, an unusual position for a flagpole; in the next place, there was no pulley, ring, or cord by which to attach a flag; finally, there were elsewhere on the boat two vertical staffs from which flags were occasionally flown.

Dewey (1910: 68–71; 1933: 91–94) takes as paradigms of reflective thinking three class papers of students in which they describe their thinking.

I formed the conclusion that the pole was set up for the purpose of showing the pilot the direction in which the boat pointed, to enable him to steer correctly.” (Dewey 1910: 69-70; 1933: 92-93) : “In washing tumblers in hot soapsuds and placing them mouth downward on a plate, bubbles appeared on the outside of the mouth of the tumblers and then went inside. The presence of bubbles suggests air, which I note must come from inside the tumbler. Could the air have become heated after the tumbler was taken from the hot suds?
