If you are an experienced facilitator in face-to-face settings, you are already familiar with your role of helping make sure that learning happens. You have a bag of tried and true tricks, and you know how to engage learners. These skills will stand you in good stead when you make the move to online facilitation. Your role has not changed, but how you carry out that role might.
The biggest difference is that you will be using technology to communicate with participants. As an online facilitator, you may be communicating through text or via a headset and a webcam. You may be presenting and reviewing information in a traditional text-based format or you may be listening to audio clips or watching videos. The technology can open a new world of facilitation possibilities! Embrace it, and don't be afraid to explore, learn and discover.
