How I Use It
In the middle of the lesson I can have students answer a question so I get instant feedback to see if they understand. I also use it when asking an opinion question which is better than raise your hand if you agree kinds of statements.
Works great for comprehension checks or class input. You can set up y/n, t/f and open ended questions. Students can use their phone or web browser to input information. You can even embed live results into your powerpoint (2007 or higher).
