What: The most important principle of a good presentation is that the visual content should dynamically advance with your narration. Make content appear (click-by-click) at the level of "paragraph". If you present an architecture, make the main components appear click-by-click as you explain each part.
How: Use power point, with "Appear" animation. Do not use latex or Google-docs.
Good examples (not overdoing it ) example1 , example 2 ICLR2021
(2) Always write the key message
What: Do not leave important messages to narration-only. Some in your audience cannot hear you well (foreign accent), and most Israeli student mispronounce many words (differ, attribute, module)
How: You can add a banner "Appear" on top of your slide. Or at the bottom.
(3) Keep it moving: 30~60 seconds per slide
