The philosophies of this book are just-in-time-erudition, learning by case in point, and Learning by doing and Demonstrating. Just-in-time-erudition means that students learn a concept, theory and/or technique at the time they need to use it. Therefore, for this book at each part, it includes exercises to help student assess their understanding after reading and practicing about the concepts and techniques. Learning by case in point means that student are provided numerous examples and illustrations to facilitate learning. I do believe that students do not really comprehend a concept until they have successfully applied it.
