I enjoyed this book. I got a lot out of it. It was actually good to read a theory book of my own choice and not one assigned to me or required for assignment purposes. Now I hope that doesn't sound too strange... wanting to read a book on theory. Well when it comes down to it, I would much rather read a novel but from time to time I enjoy being inspired to teach my students.
I will put up a link to my review and you can get an impression of why I found this book insightful.
