how to make a good PPT presentation

In my opinions, a good PPT presentation should include following key points.
1. Every slide should have one informative title.
2. The background introduction should be enough. You need think about your audiences, who have
not too much knowledge about your research. You should prepare it carefully with figures, tables, and sentences.
3. The pictures should be beautiful, accurate and easy understanding, and the font size should be large enough.
4. The references should be added.
5. Use short sentences.
6. Keep moving your body from time to time.
7. Show your passion and enthusiasm.
8. Speak aloudly.
9. Make eye contact.
10. Ask a question during the presentation.
11. Vary your voice infrequently .
12. Begin by letting your audience know that you are happy to present.
13. When possible, relate your topic to other fields.
14. Restrict each slide to a small number of lines.
15. Use key words and phrases on the slides instead of entire sentences.
16. Avoid filling slides with equations and formulas.

Overall, have considerations for your audience. If they are happy, then you do not have any trouble.
