I do not think that a lot of what is said in this book is "common sense", as some other reviewers have stated. There is nothing "common sense" about organizing a grade book or effectively introducing a classroom management system into your classroom - these are things that are somewhat esoteric to the newbie and not the things that are taught in most degree programs. Granted, I do not need to be taught or told to dress professionally - but look at the way some teachers DO dress today - apparently it is not "common sense" for all. While I would not agree with all his methods (some of his classroom management techniques, though well meant, could be hurtful to sensitive students) and some of his statements of effectiveness sometimes seem to give the reader the impression that if you do "A", "B" will automatically happen (and it doesn't, of course - all students and classes have their own dynamics - there is no "one-size-fits-all") his philosophy and objectives are clearly explained and discussed. He has a method which he stands by and which has been effective for him and countless others. Since I have read the book I have implemented some strategies into my classroom and seen great results. His intention is to inspire teachers to be lifelong professional educators and to continue to strive for excellence. He values student success and provides a detailed strategy for teachers that may be "stuck in a rut" or may be new to the profession. He also provides information of interesting results from research studies in the area of teacher/student instruction. Again, while I can not totally agree with everything in the book, it is, by far, the most valuable resource I have seen for new teachers and for teachers that want to continue to master their profession. To say that it is all "common sense" and a "waste of time" is, I think, missing the entire point of the book - when it comes to becoming a better educator, there is no time wasted in trying new techniques and broadening your scope of knowledge.
