This was the main textbook in my Curriculum and Instruction class, and it's okay, but VERY redundant. It says to start your lesson by deciding what you want your students to learn (well, duh!) and then don't let a bunch of nice-to-know-but-not-really-important facts get in the way (I guess that's what comes from the SOLs and stuff). And it hammers home the idea that students can LEARN something without really UNDERSTANDING it, which seems a little obvious to me.
All in all it's not a BAD book, but Id recommend something by Robert J. Marzano instead. We also used "Classroom Instruction that Works" in our class, and it was much better -- easier to read, not as boring or textbook-y, and more practical application type stuff.
