One of the complaints I have had about virtual summits is that they are terribly passive. In other words, the attendee is presented with a screen to watch while someone talks or makes a presentation. There is literally nothing to do except watch and think.
At the end, there may be a few questions asked by those who are the quickest thinkers ,or the most extroverted. But anyone who needs a few minutes to collect their thoughts is likely to miss the window.
I just wrote an article exploring some research on this topic, which I am using the design the Time Blocking Virtual Summit. It’s entitled Interactive Learning Leads to Better Results, Surprising Students.
