I used Vialogues to comment and react to “No Digital Facelifts: Thinking the Unthinkable About Open Educational Experiences” video by Gardner Campbell.
As a process within this tool, I was able to use Vialogues to mark the timestamp to call out the pieces that struck me as I watched the video. I then was able to expand upon the pieces I wanted to reflect upon, by clicking back to the timestamp to listen again.
Others can go in and add to the comments or reply to mine. You can also add short multiple choice/answer polls or quizzes.
