Poll Everywhere is an application for audience participation. You can create a poll for a specific class and students can vote using text messages or their laptops. The polls update seconds after students enter their votes, and results are displayed on the screen. You can choose to display the poll within a web page, or embedded in a presentation. Polls can be used to gather data, take the classroom temperature, or they can be more open-ended polls, allowing students to type in questions as they come up.
