It's no surprise that a lot of educators who blog also share a love for professional development. The last presentation/course that I developed "50 Sites in 60 Min" did quite well online that I figure why not turn my digital books into slide shows. (BTW if anybody wants to email me about PD and has questions on how I do 50 Sites or any other topic please let me know.)
I'm in the process of creating 6 slide shows that can be used/edited in anyway that a user sees fit. Ideally, this is not designed for PD but can certainly be used in this manner or any other way. Each volume will focus on a different topic.
