Google+ for Online Classes

Google+ offers a host of features to help you connect with your students and make your classes more interactive. Create a Circle for your class and start discussions, share assignments and post private messages to individuals or the whole group. Use Sparks to find and share the latest articles, videos and blog posts on your topic. Start a Hangout for a live video discussion/demonstration or use the Huddle to send updates to your class on the go.
