I had the opportunity to 'hangout' with a friend last week. At first it seemed to be just another video chat, but then I realized how much more it could be! Google+ Hangout allows for collaboration and in education, it's a great way to share and learn. If you are new to Google+ Hangout, take a look at this wiki that describes how to use this Google feature. What have you used Google+ Hangout for?

In our office at TIE (Technology and Innovation in Education) in South Dakota, we provide Tech Tuesday's using Google Hangout. This allows anyone who is a TIE member school access to a one hour interactive chat and experience with new tools and resources on the web. This provides experience with 2 technology tools at once - Google Hangout and whatever tool is being presented.
