This is from Chris Mattia, an original member of Lynda.com and a senior consultant with Callinectes Training. Chris was instrumental in helping develop the most recent revolution of web pages as a part of teaching, learning and scholarship, and his video series for Lynda.com is an excellent compendium that goes over the most basic and some very specific instances of how to engage WordPress in the classroom. I cannot embed as it is part of the Lynda.com site, but a Seattle Public Library card will get you access (and you can get one for free online!)
And a few videos I built...not nearly as good as Chris, but maybe more pertinent to what we do.
The basics of building a page.
Adding an image to a page.
Embedding video into a page.
