How do I hold a synchronous online meeting / live classroom session?
CTS plans to purchase individual Zoom Pro accounts and have them available for faculty to use to schedule online live sessions for their classes. With access to one of the Zoom Pro accounts, you can schedule your live class sessions and provide the resulting links to your students through your Moodle course. It won’t be as tightly integrated into Moodle as the Collaborate Ultra solution, but it will be much more cost effective.
If you have a Google account, you can set up a Google+ Hangout.
