This book provides a general overview of critical thinking and gives some recommendations for how to evaluate different aspects of thinking in your classrooms. Overall, I would say that the author tries to give a big picture view of the field, so it comes across as a bit light, especially if you have read much on critical thinking in education. However, there were two things that I liked. First, there are a lot of sample rubrics provided, which I found useful in thinking about how to grade thinking by students. Second, I really liked the chapter on creativity. The author hits the nail on the head when she says that creativity is often mistaken for artistic ability or attractiveness. If you are evaluating creativity in any of your classes, it's worth reading that chapter.
