Make the content easily understandable.
Audience has short attention span.
Simplify the message.
Reduce quantity. Leave them wanting more.
Be entertaining. Maybe some humor.
Be prepared to stop at anytime.

How to Give a Bad Talk
Dress sloppily
Be hesitant and apologetic
Use crowded slides with tiny lettering
Show complex equations quickly
Read from a manuscript
Speak quietly and too fast
Dolan Hefei 2008 20
How to Give a Bad Talk
Face the screen
Avoid eye contact with audience
Distract the audience by jingling coins or keys
Say “uh” or “you know” frequently
Keep talking after your time is over.
Dolan Hefei 2008 21
How can we prepare good slides ?
Emphasize the main points
Dolan Hefei 2008 22
Each slide should have a thesis.
Give main point in title
< 6 main points
Large lettering (> 18 point)
Graphs and pictures
Dolan Hefei 2008 23
Use < 6 statements per slide.
List most important ideas.Give supporting facts (if needed) in smaller font
Space between statements.
Too many statements make retention difficult.
Short term memory saturates ~ 6 facts/slide.
Audience remembers pictures and graphs better.
