I especially like the idea of using Hangout for office hours. I like it because you can have 10 people online at a time and again, it's free and easy to use. I've tested it with friends on campus - it is easy easy!
While exploring Google tools/drive/resources (What DO you call this thing?) I found this article on their Course Builder on Edutopia:
Google's Open Course Builder: A Giant Leap into 21st-Century Online Learning which led be on to this online course in Constructivist Pedagogy: http://www.thirteen.org/edonline/concept2class/constructivism/index.html .
I truly could surf articles related to online education, pedagogy and instructional technology for days, weeks and years! Did I mention that's what I've been doing since the late 80's? I remember struggling with the concepts of Industrial Technology (my undergraduate major) and Instructional Technology. To me these were the same species of animal minus a table saw. As graduate schools continued and I began to work in the field, I continued to see the overlap but the line became more defined and then blurred. This is what I try to help our professors do - draw the line then smudge it as they integrate technology into their courses or when the redesign their courses to being online. It's fascinating watching the faculty change their teaching processes and seeing the difference in method over time impact student learning. It's a slow process but one which is infinitely interesting!
So what do Google tools offer the teaching professor or classroom teacher? Stay tuned - I'm working on that! What do you think?
