Vialogues is a website that is designed to enable users to host conversations around a video. Users can upload videos to Vialogues or use YouTube videos as the centerpieces of their conversations. After you have selected a video from YouTube or uploaded a video of your own, you can post poll questions and add comments that are tied to points in the video. Your Vialogue can be made public or private. Public Vialogue's can be embedded into your blog or website.
Applications for Education
Vialogues is similar in concept to TED Ed in that you post a video for question and answer discussions. If you have a video clip that you want students to respond to at their own pace, posting a Vialogue could be one way to accomplish that goal.
