Advice and in-class activity for audience adaptation
This post at Tweakyourslides covers some of the why and how about getting the audience engaged in a presentation rather than leaving them as passive observers.
The post not only covers advice to share with students about encouraging an audience to act, it also has advice for teachers about having students facilitate class discussions or lead topics. There are several author links, a description of a class activity and a link to a TED talk on audience participation.
