Tips for presenters
1. Don’t memorize your presentation. If you need to, make brief notes, possibly on small cards, to guide you.
2. Practice many times.
3. At the start of your presentation, relax, take a deep breath and wait until the audience is quiet.
4. Speak loudly and clearly, and use your voice for stress and emphasis.
5. Use gestures to show meaning. Make them slowly and clearly.
6. Use simple visual aids that everyone can see.
7. Make eye contact with the audience as you speak.
8. Don’t say “Finished.” or “That’s all.” Smile and say “Thanks you”.
9. Think about how you can do better next time.
I think number 4 is the most important , speaking loudly and clearly is essential. Tip 2 is also important as practice should be done over and over again , to avoid any mistakes while presenting.
