presentation skills by teaching classes at local colleges and training sessions at work. Language has never been an issue for me, but the speed was, I tend to speak too fast when I get excited or nervous:+D I still catch myself doing that from time to time, but it has largely improved.
The following are what I consider the most important things to be a good presenter:
1. Be prepared: We should not only know what we are talking about, but also anticipate what questions the audience will ask and how to answer them.
2. Engage the audience: good interaction and eye contact with the audience not only will boost the presenter's confidence and comfort level, but also send the message to the audience that they are welcome to participate and they are part of this presentation. I always invite someone I know to my presentations, so I know I will have at least one person to "pick on" if I need to.
3. Speak slow and calm: Never never never rush through a presentation, which only tells the audience that you are not interested in being up there. Something I'm still working on.
4. Relaxed posture and hand gestures
5. Be presentable: be well dressed, look matters, a lot!
