Critical thinking as an educational ideal：批判性思维作为一种教育理念.docVIP

Critical thinking as an educational ideal The following remarks about critical thinking as an educational ideal incorporate and adapt material from chapter 4 of the book Evidence-Based Practice: Logic and Critical Thinking in Medicine, co-authored by Milos Jenicek, MD, and myself, and published in 2005 by American Medical Association (AMA) Press (Jenicek Hitchcock 2005).

Reflective thinking in Dewey’s original sense begins with the definition of a problem, often a problem of understanding why a certain phenomenon occurs. One or more hypotheses are proposed as possible solutions. Then some method of systematic observation or experiment is devised as a test of these hypotheses, and carried out. The results of this investigation are analyz
