It's easy and it's amazing! We recently used Google Moderator with over 100 high school students so they could submit questions they wanted to ask the superintendent - but they also were then able to vote for or against other questions as well as respond to each other's ideas.
Google Moderator is being used in the Jeffco Budget process, professional development planning, naming the new Jeffco wifi network. It has also been used by the White House and Fox News.
Take a look at this video for a quick overview of how one teacher has used it in the classroom.
Now give it a try! "How can Google Moderator be used in education?"
