I keep coming back to this book for practice ideals.... mental stamina, clear reason. Whether you are a newbie or a veteran teacher looking to improve cooperative group work in your classroom, this is the book for you. I have a newer edition than this one, and secondary teachers might flip through the book thinking it looked too elementary in focus....it isn't. I'm a 9th grade science teacher and find that the protocols are right on point. While there may be a couple of things that I wouldn't use, the vast majority can be used as is, with a few things being modified in a secondary setting.
