I am not a big fan of the way the lessons in this book are laid out. I prefer to know what I'm learning BEFORE being taught how to do it. I have seen the texts other ASL classes use and they seem more logical in their progression. This book is also guilty of "using" signs in practice sentences it doesn't teach in the lessons. However, I now know ASL, so I guess it wasn't all bad.
That said, the spiral binding of this book SUCKS. Strike that, it REALLY REALLY SUCKS!!! Yeah, it lies flat... in pieces. This book was in shambles after ASL 1. By the end of ASL 2 most the pages were falling out. Very annoying. Fortunately, ASL 3 uses a different book so I can put this one out of it's misery.
If they come out with a non-spiral-bound version, OR use sturdier materials, I would generously bestow another star.
