I found several helpful tips, techniques, processes, and assignments in here, including some I already use. Much of it is common sense, but that's what makes it good -- it doesn't demand that you rethink your entire approach, but rather just gives a few practical, simple-to-implement ideas you just might not have thought of yet.
I especially appreciate that I didn't have to dig through chapters of unnecessary anecdotes and cute writing to find the good tips -- who has time for that? Teachers are busy people, and this book catered to us -- it got right to the point, with no fluff.
The writing is mediocre, but who cares? I found some good ideas, and that's what I was looking for.
