Michael Zimmer (@MZimmer557), a Technology Integration Specialist in Western Kentucky, shares Tools for the 21st Century Teacher, a wonderful little e-guidebook offering a basic introduction to most things social media and discussion about how they may be effectively integrated into instruction. Among the many tools covered are Twitter, Diigo, Prezi, Evernote, Wallwisher, Skype.
I am absolutely going to use this at inservices. Michael generously allows printing and sharing of the book for in educational settings.
