Query: not too impressed

The problem I had with this book is that large parts of it are not directed toward the substitute teacher at all. In Chapter 3, he spent most of the time discussing what the regular classroom teacher should do for the substitute, not what the substitute should do with the plans. I have no control over what the regular teacher leaves or what the administration does, so this is not helpful to me at all.I dropped my teeth when he suggested that if a classroom situation becomes untenable, or you start to lose control, you should "walk", that is, leave the classroom. Huh? I would never be called back to a school if I were to do that, not to mention that it strikes me as a bit cowardly. The only excuse I could think of to walk out on a class is violence, and then you're going to leave the other kids in there? No way--the pay for subs is low, but I'm a mom as well as a teacher.Some of the advice was good, but overall it's not a useful book.
