Effective or “high value” PowerPoint presentations take some planning and work. Here are some tips (by no means comprehensive) on how you can improve your PowerPoint presentation,1-4 divided into 4 stages:
Stage I: Planning for your talk
- “Know your stuff”
- Prioritize the main objectives of your talk given time constraints ie, “What would you like your audience to really take away from your talk?”
- Accept the fact that you will not be able to cover all that you know about the topic during the allotted time
- Think about how you might keep your audience engaged throughout your talk as you introduce topics and concepts!
Stage II: Preparing your slides
- General rules
- Keep them simple (“Less is more”)
- Minimize number of slides eg, average no more than 1 slide/min
- Minimize number of concepts/slide eg,1/slide
- Minimize clutter
- Avoid “apologetic” slides ie, if not easily readable or visible or “too busy”, don’t use them!
- Practice, practice, practice and edit as needed
- Keep them simple (“Less is more”)
- Minimize number of words/slide eg, 6×6 rule, maximum 6 words/line, 6 lines/slide
- Use easily readable font types and sizes
- Minimum 24 for small rooms
- Minimum 36 for larger rooms
- If not readable 10 feet away from monitor, don’t include
- Check spelling!
- Choose high contrast colors between background and text eg, black text on white, yellow on dark blue background, not red on green
- Avoid reproduction of large tables with tons of data that cannot be read or can easily overwhelm the audience
- If you use large tables, zero in on a particular section and display a magnified version of that section so that the audience can follow along with you
Stage III: Presenting your talk
- Remember, you are the presenter, not PowerPoint
- Engage the audience from the beginning to the end
- Beginning: Use a “hook” ie, why should the audience be interested in your talk?
- Maintain eye contact with the audience
- Be dynamic/animate
- Use speech intonations as if you are having a conversation with the audience
- Do not read slides word-by-word
- End: Highlight your take-home points eg, “if you don’t remember anything else…”
Stage IV: Post-Presentation
- Ask for feedback from colleagues, audience, coordinators, etc…
- Self-reflect ie, what went well, what didn’t go so well?
- Apply lessons learned to your next PowerPoint presentation!
