There is so much room for improvement with most people's presentation skills. I include myself -- and one great way to hone those skills is to get videotaped giving a presentation, or part of one.
Huthwaite uses an acronym to overview the skills used by effective presenters. I'll share the acronym, but check out their website for the details...
- Structuring
- Integrating
- Elaborating
- Variety
- Emphasis
Whatever acronym or approach you use, hone it - evaluate it -- and get feedback!!
