If you’re pushed for time, I recommend the Getting Started, Live Polling with Vevox and How to Display Responses. You may want to turn Messaging OFF the first time you use it – and you can always try using it once you’ve gained some experience and confidence with the basic polling.
One key piece of advice is to always connect to Vevox using a wired connection when teaching (i.e. do not use Eduroam). This is because the Wi-Fi can become unreliable if too many devices in the room are trying to connect, and these days lots of students have two devices each, typically a phone and laptop.
You can extend your PC’s display in CLS rooms so that you can view the Vevox dashboard on your main screen while your PowerPoint slides or the Vevox Projector are shown to your students on the extended screen.
