Web resource for delivery
The blog at Ethos3 gives five tips for a more authentic delivery. These are the types of tips that I encouraged for students because they are perfect for the classroom setting, and are becoming more acceptable in other settings as well.
The article also links to a CBS Moneywatch article on the same topic with additional tips. Neither article is very in-depth on the topic, but they provide a nice list of suggestions and the rationale for why they work.
I like to have as much literature to back me up as possible when I tell students “Don’t memorize,” “Tell stories” and “Respond to the audience while you speak.” These articles back that up.
The CBS article also contains a list of references to Harvard Business Review. Unfortunately, the links are broken but it may be possible to find the articles (which will likely require a subscription or have a charge) and the book through another means by using the reference information.
