Design of the slides
– We conducted a retrospective cohort survey including all people attending the visit of the park
– A case was defined as a papular or papulo-vesicular pruritic rash, among participants, 12 hours or more after the exposition to seawater
Avoid karaoke slides
– Survey
• retrospective cohort
• all visitors to park
– Case definition
• rash (papular or papulo-vesicular)
• > 12 hours after exposition
Bullet points
– Use keywords
– Less than 12 lines
– Maximum 5 words per line
– Break line
properly

Prepare a script
• Necessary to most speakers
• beginners
• non-native speakers
• Decreases sources of uncertainty
• Reassures you
• Allows precise timing
• Facilitates coaching
• In the presentation software
• Copy the content of your slide into the lecture notes
• Edit to make full sentences
• Add “off” comments:
– “Use pointer”
– “Pause”
• Use large fonts (e.g., size 16)
The script
“lecture notes”
– Practice on your own
– Walk through your text
• is the sequence logical?
• is all relevant information there?
• remove redundant information
• avoid very technical details and jargon
– Watch time, pace and clarity
– Practice with critical colleagues
Does our message come across?
Prepare the speech
– Day D
• Get prepared
rest, healthy distraction
no stimulating substance, no beta-blocker
arrive early, explore the facilities
• Your look
feel comfortable, be yourself
but dress formal
don´t distract the audience with your «look»
Delivering the presentation
– Time T
• Nerves: normal, good stimulant
• Going on stage
memorise the first sentence
install your material, look around
set micro to feel comfortable
Delivering the presentation
• Stand upright
• Mind your pace of speech
• Mind your volume
• Make eye contact
• Interact with audience
• Refer to slide
• Finish on time
On stage
• Hands in pockets, tics
• Unnecessary movements
• If you tremble, minimize the use of the pointer
• Overcrowded slides
• Apologies
Avoid
– Practise with you colleagues
– Think of possible questions
– Prepare short answers
– Prepare two or three more slides
Prepare for Questions and Answers
– Listen
– Write (may be more than one)
– Thank the person for asking the question
– Answer briefly and precisely
– Avoid being defensive
Questions and answers
Do not panic!
• acknowledge: “This is a valid point”
• sympathize: “This is a point that needed to be raised”
• respond: “I am now going to clarify”
• Ask for the audience’s opinion
Challenging questions
my SOCO …
