I've also used this book over and over for presentations. Why didn't I give it 5 stars? I don't really know. It is awfully good. OK, OK, I just went back and changed it. When you use something all the time, you must like it enough to rate it highly. I've heard Harver Silver speak more than once and respect his work. I continue to be fascinated by multiple intelligence from the time I heard Roger Taylor had us work with them in-depth in the mid-90 duringin his week-long G/T workshop one summer. I was hooked and have continued to delve into new research. This book mentions eight, but not the two more that have been toyed with. I am using it to prepare a research paper to support a presentation I am giving soon for a recertification, and I am finding new and wonderful things about how the brain learns, and what we need to remember to teach these incredible beings we have as our students.
