Instructors can embed polling questions into video or audio media, creating "interactive media", then post that media into a course, or embed it into an LMS/VLE course page (such as Blackboard, Canvas, Moodle, Brightspace, or Sakai).
The playback for interactive media looks like the figure shown below. It plays like a normal video but has polling questions in it that prohibit viewing sections of the video until you have responded to the questions. In the below figure, the pins on the timeline indicate the locations of those polling questions.
Click Play on the video.
When your playback reaches a polling question, the video pauses, and the polling question appears in the viewer. You may need to use the scrollbar, identified in the below figure, to see all of the poll options, depending on the length of the question, the type of poll, and the number of response options.
How you respond to the polling question depends on the type of activity or question it is. You may need to select from a list of options as the polling question in the above figure indicates, or reorder a list, or enter a response into a text box. See Responding to Polling Questions if you need specific instructions for responding to each type of activity.
After you enter your response, click Submit.
Your response along with the Correct response appears. In addition, if the instructor has provided feedback for the polling question, you may see that below the response area.
The Submit button turns into a Continue button, allowing you to continue viewing the video, up to the next polling question. Alternately you can click Play on the playback bar to continue.
Note that if there is a transcript for the media, the transcript will show, but the text is gated by the polling questions, just like the media playback is. You also cannot download the transcript until you have responded to ALL of the polling questions.
Finally, if there is a discussion post with a media (location) reference beyond an unanswered poll, you will not see that post until you have answered all polling questions prior to the referenced location. The Discussion panel does provide a notification to indicate when posts are currently hidden.
