Question

What type of discussion requires a lot of active participation from the aundiance?

Answer 1

I would say that it depends on the audience. Personally, a debate regarding ethics and moral dilemma is interesting. Read The Fat Man and the Impending Doom. It's just one paragraph so it's not going to bore audience.

I believe that this type is a lecture-forum discussion.
