Strategies for Teaching Critical Thinking. Yes, it can be taught. And this brief essay has some good ideas for teaching it!
From the site:
Critical thinking skills figure prominently among the goals for education, whether one asks developers of curricula, educational researchers, parents, or employers. Although there are some quite diverse definitions of critical thinking, nearly all emphasize the ability and tendency to gather, evaluate, and use information effectively (Beyer, 1985).
In this digest, we discuss skills related to critical thinking and three specific strategies for teaching these skills: 1) Building Categories, 2) Finding Problems, and 3) Enhancing the Environment.
