1. Use simple, easy to understand visuals
Visuals often help make a concept clearer than mere words can. This is especially true of difficult to understand and/or visualize scientific or technical information. Your visuals should be easy to understand quickly. Use a lot of white space. Use imagery over text, and use text sparingly.
2. Use clear and natural body language
Often, if you can “show what you mean” via body language — hand gestures, body stance — it can make a concept more clear. It is very important, however, that the gestures seem natural and not forced. Also, using body language can put you and your audience at ease. When people are more relaxed, they can convey and understand complex, scientific and technical information more easily.
3. Use easy to hear language, making it more conversational
Many times words that are perfectly understandable when read, can be misunderstood when heard. Also, a person who is reading can always go back and read an unclear sentence, however, when someone is talking, they can’t go back and listen to the sentence again. This is even more important when you are trying to convey complex information.
4. Keep the speech simple
For most presentation lengths (an hour or less) cover no more than three to five ideas, three is better than five. If your presentation is longer, you can go up to seven. No matter what the topic, people can only understand so much. Much more than three to seven ideas in a speech and people will either lose interest, lose track or both.
5. Use vocal variety
Vocal variety adds personality, interest, and emphasis to your speech. It keeps people interested, which is very important when discussing technical information.
