Here is another free, open, wiki-based, online professional development course: Mobile Multimedia: Podcasts, Mini-Movies, and More on Handhelds.
In case you missed it, another earlier free, open, wiki-based, online professional development course I published earlier was Hands On: Using Mobile Technology to Differentiate Instruction. There is some overlap between these courses, but also some very different content.
Stay tuned for more of these. I am becoming a believer that wikis like these are a great professional development tool, because they extend learning beyond a f2f workshop. And because these are free and open resources, you may use them for whatever purposes you’d like, including using them for workshops at your own schools and districts. Please also add to them. (If you’re about this, make your additions in the Discussion tab.) I hope they are useful.
