Are we really serious about critical thinking? Are we really serious about higher order thinking? And are we serious about teaching students to think? And to evaluate, integrate, synthesize, compare and contrast? Some would say yes and some would say no, and others would hedge their bets and provide a long diffuse answer which rambles and circumvents the issue. Critical thinking is much like the weather; people talk about it, but very few people do anything about it. However, the authors of this edited book are out in the field, in classrooms, colleges, universities and libraries across the world trying to enhance critical thinking, promote it and assess and measure its growth and development.
