[quote name='Dead of Knight']Some general tips. Currently taking a class that involves a lot of speaking and trains you on this:
1. Have a glass/bottle of water up there. If you're gonna say um or are at a loss of words, take a sip.
2. Don't waver around, put your hands in your pockets, any shit like that. It really is distracting to the listener.
3. Practice!!
4. Have notecards to refer to, but don't rely on them.
I can post more later when I'm not so busy.[/QUOTE]
I agree with this, with some caveats:
don't practice if it isn't a formal speech. Unless you're presenting "Catheter-Urethral Bonding: A Causal Analysis," (or whatever you kids do in med school), practice isn't necessary. If it's an informal talk, notecards and thinking over it will suffice (compared to, say, standing in front of a mirror and practicing it verbatim).
the formality of the speech is related to your posture; be aware of that. If it's formal or research, make like presidential candidates during debates: hands on the podium, look down to grab a couple sentences, look forward, scan the crowd, wash, rinse, repeat. I know this is important because I've done a formal research presentation of the "where the
are my slides with the regression results!?!?!?" type of preparedness, so I know what happens when formality is absent when it shouldn't be. If it's less formal, go for the "Steve Jobs Keynote Address" style - walk around a bit, use your hands (not too much), mix in some interesting anecdotes.
As someone who gets caught up in a colloquial loom of tangents and asides, the most important thing to keep in mind: stay on point, and never lose sight of your overall thesis.
Knock 'em dead.
