  • 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.Courtesy of Brian Dodd

    Dolan Hefei 2008

  • Repeat important content.People dont listen perfectly. Attention wanders -- distractions Other thoughts work, family, entertainment,

  • Interact with the audience.Get acquainted beforehand, if feasible.

    Look at many people.

    Encourage their questions. Paraphrase the question. Admit what you dont know.

    Ask them questions.

    Dolan Hefei 2008

  • How to Give a Bad TalkDress sloppilyBe hesitant and apologetic Use crowded slides with tiny letteringShow complex equations quickly

    Read from a manuscriptSpeak quietly and too fast

    Dolan Hefei 2008

  • How to Give a Bad TalkFace the screen Avoid eye contact with audience

    Distract the audience by jingling coins or keysSay uh or you know frequently

    Keep talking after your time is over.

    Dolan Hefei 2008

  • How can we prepare good slides ?Emphasize the main points

    Dolan Hefei 2008

  • Each slide should have a thesis.Give main point in title

    < 6 main points

    Large lettering (> 18 point)

    Graphs and pictures

    Dolan Hefei 2008

  • 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.
