Poll Everywhere (http://www.polleverywhere.com) is an web-based application for audience participation. It can bring more interactivity into your classes to further engage students in the learning experience.
Quick link: (Request an instructor account.)
Using a simple web form, you can create a poll for a specific class and students can vote via cell phone, text messages, or any web-enabled device (smart phones, tablets, laptops, etc.). The polls update seconds after students enter their votes, and results can be displayed on the presenting screen (or not if using the poll for quizzes). You can choose to display the poll within a web browser, or embedded in a presentation. No special software or equipment is required.
