Teaching critical thinking

Edward Charles Francis Publius de Bono is a bona fide genius. The author, inventor, Rhodes scholar and Nobel prize-nominated economist graduated from college at age 15. In the field of education and business, he is famous for originating the term lateral thinking. In his spare time, he also wrote Six Thinking Hats and several other books on creativity. Of all his contributions to the field of education, there is one critical thinking method that I use in classes more than any other: the PMI, a brainstorming model built on the categories of plus, minus and interesting.
