Think like a TedTalk presenter.
Some strategies that may or may not work for you...
- Focus on story telling for the presentation.
- Perhaps focus on illustrating your key findings in some memorable and distinctive way.
- Perhaps try fewer slides
- Perhaps put some of the text into your speech rather than on the slides.
- Perhaps focus on your key findings; they may relate to the case data or they may relate to the method you employed, or you may wish to cover both.
