"Google Hangout is an excellent service that enables both one-on-one and group chats with up to ten people at a time.Google Hangouts are not all video based. You can hold a hangout using only the textual chat functionality or you can add voice. There is also another great feature called hangout on Air. A Hangout on the Air is a Google hangout that is broadcast both on YouTube both through your Google+ page . It's a great way to have a "public" event or get more people involved in the conversation!"
In class, are your students texting or on task? Why not both??
TodaysMeet helps you embrace the backchannel and connect with your audience in realtime. Encourage the room to use the live stream to make comments, ask questions, and use that feedback to tailor your presentation, sharpen your points, and address audience needs."
