I have used this in my classes and love it! The free Poll Everywhere mobile app is perfect for responding to polls, presenting polls, and clicking through PowerPoint presentations. Use it to... 1.) Respond to polls: Audience members can use the app to respond to the presenter's questions live. 2.) Poll an audience: Presenters can ask the audience questions and display poll responses live. 3.) Navigate in Powerpoint: Presenters can control the flow of Powerpoint presentations using a smartphone as a wireless remote. Participants Audience members or students can easily respond to polls or vote using the app on a smartphone or tablet. Aside from the app, they can respond via web browser, text message, or Twitter. Presenters Professors, teachers and presenters can create and display questions on the fly, including Q&A and multiple choice polls. Questions can be presented directly from the web or embedded in a PowerPoint or Keynote presentation. Audience responses are displayed in real-time. Great for classroom participation, or gathering opinions from the audience. PowerPoint Remote Presenters using PowerPoint can use the Poll Everywhere mobile app as a presentation clicker, to navigate through your PowerPoint presentation with ease. It has a slick, streamlined design and a set of polling controls built-in. Key Features: * Create or answer multiple choice, true/false, open ended, ranking poll, and clickable image questions. * Participants are automatically shown the presenter's current question, for quick and easy participation. * Watch results update live. * Click through a PowerPoint presentation with the included Presenter Remote feature.
