Delivery, Part II: What the audience sees
Body Language
Facial Expressions--including eye contact. Try to make facial expressions a little larger--as in Theatre--to communicate with entire audience. Exercises include "change face" or "switcheroo game."
Gestures: Use what works in your normal conversation. Also Gesture can be used to clarify information, as in demonstrating contrast "on the one hand," or "on the other hand." Circumscribing with your hands to convey sizes and shapes is another way of presenting information.
Avoid crossed arms, hands in pockets or the "fig leaf" pose.
Movement and Posture/Stance: Moving from side to side is ok if not too energetic and distracting; make sure to keep eye-contact with audience during movement from side to side. Like gesture, movement from side to side can convey contrast, different points of view. Moving forward can add emphasis. Stance/Posture should be confident, alert, erect.
Avoid crossing legs, aka "the pretzel."
Proxemics: Your physical distance from the audience suggests your psychological relationship with audience. A speaker whose back is against the wall or who is off in a corner is "distant" from the audience, suggesting fear of the audience. Use of a podium creates artificial distance making a speech more formal or, more negatively, putting up a barrier between the speaker and the audience...which is why we don't use podiums in this class!
