A good presentation should be attractive. How to make an attractive presentation? I think it could concert in different aspects: Strategy, context of talk, and visuals .
In terms of strategies, good speakers always start with jokes, stories, or common questions. Speakers attract people’s attention directly.
In terms of context, as the same strategy of personal statement, speakers should use the simple language everybody could understand and have similar feelings easily. Using the simple words to explain a complicated topic is not an easy thing.
Finally, in visual aspect, we can combine pictures and videos together, and express our topic in visual way. All the visual stuff should serve our main idea directly. We can also talk when we show those medias.
