Looking for a way to improve your mind and make some money? Check out the latest "critical thinking" courses. Many come up on a Google search. Many promise better grades and higher test scores. Without much effort, you can create your own course and tap into this hot topic.
The only thing is, it turns out such programs don't work very well, except as a measure of the gullibility of even smart educators. A remarkable article by Daniel T. Willingham, the University of Virginia cognitive scientist outlines the reasons. Critical thinking, he explains in a summer 2007 American Educator article, overlooked until now by me, is not a skill like riding a bike or diagramming a sentence that, once learned, can be applied in many situations.
Instead, as your most-hated high school teacher often told you, you have to buckle down and learn the content of a subject--facts, concepts and trends--before the maxims of critical thinking taught in these feverishly-marketed courses will do you much good.
