I completed Prensky's book and was pleasently surprised at the knowledge I gained from it. The book gives many definitions relevant to 21st century learning, and I plan on keeping the book handy in case I ever need to look up something. While some chapters were pretty lengthy, it was an easy read, and it includes some great knowledge as well as suggestions. If you are contemplating taking on the partnering approach, this book will give you great insight on how to do so (and it may just persuade you to implement partnering if you're on the fence about it :) ).
I have included a link to purchase this book, although I am sure you could conduct your own research to figure out where to get the best deal. I hope you get the opportunity to read this book to further your knowledge on the topic of the partnering pedagogy, and I hope you enjoy it as much as I did!
