When you read about conference presentations and college classrooms, you might also hear mention made of the "back-channel". Wikipedia defines this activity as "
the practice of using networked computers to maintain a real-time online conversation alongside live spoken remarks." The advantage of this kind of contribution is that it allows those present to comment on the session, ask questions, request clarification or add missing details; all in real time. Some conferences even allow the back channel to be projected up alongside the PowerPoint! While some are using Twitter to create this, the site "TodaysMeet" lets teachers and conference presenters easily set up a space for participants/students to respond. "Encourage the room to use the live stream to make comments, ask questions, and use that feedback to tailor your presentation, sharpen your points, and address audience needs." Its easy interface and simple design makes this a very easy web-app to use. Give it a try!
