Presentation Skills
Improve your English ASAP: the spoken word (ear, mouth); the written word (eyes, pen / keyboard).
Read books about technical writing: The Elements of Style (Strunk and White) A Handbook for Scholars (Van Leunen) Towards Clarity and Grace (Williams) How to Write Mathematics (Steenrod) Lessons from a Lifetime of Writing (Morrell)
Presentation Skills
Think backwards: what do you want people to remember from your talk? Don’t say everything. Simplify.
Rumour: people can only remember 5 new things from a talk. Rule of thumb
Of course rules are made to be broken, but still: be aware of which message you want to send, and what you want your audience to remember.
Make at least one point comprehensively.
Presentation Skills: The Plan
Planning is not like playing Lego. It reflects your understanding, and thus it evolves with time.
You should not plan your talk in the same chronological order as you carried out your research.
You probably chose a logical plan for the paper. Choose a pedagogical plan for the presentation (i.e., one adapted
to the audience, the duration of the talk, etc.). Before the talk
Try to immerse yourself in what you are going to say (e.g., by giving the talk to yourself).
How to present?
Basics What is the ‘take-away message’? Keep in clear and simple and not overly
complex Know your audience to explain the ‘take-away message’ appropriately Know your subject well. Be prepared to say “I don’t know”. Understand the configurations of the venue Generally people take slightly less than a minute per slide. But,
experiment your own pace
Making your presentation Provide the outline of your presentation Start your presentation with introduction Explain the essence of your ‘take-away message’ Finally, recap the ‘take-away message’
How to present?
Preparing Slides One idea per slide Write text as newspaper headlines The summary of the slide should be the title of that slide Use simple block diagrams If graphs are used, label them and explain the meaning behind
the variables Final Words
Relax Don’t block the projection Don’t memorize or read from prepared text Keep control over questions; make sure not to be dragged of
Generic Layout of Conference Talk
Title/author/affiliation (1 slide) Forecast (1 slide)
Give gist of problem attacked and insight found (What is the one idea you want people to leave with? This is the "abstract" of an oral presentation.)
Outline (1 slide) Give talk structure. Some speakers prefer to put this at the bottom of their
title slide. (Audiences like predictability.)
Background Motivation and Problem Statement (1-2 slides)
(Why should anyone care? Most researchers overestimate how much the audience knows about the problem they are attacking.)
Related Work (0-1 slides) Cover superficially or omit; refer people to your paper.
Generic Layout of Conference Talk Methods (1 slide)
Cover quickly in short talks; refer people to your paper. Results (4-6 slides)
Present key results and key insights. This is main body of the talk. Its internal structure varies greatly as a function of the researcher's contribution. (Do not superficially cover all results; cover key result well. Do not just present numbers; interpret them to give insights. Do not put up large tables of numbers.)
Summary (1 slide) Future Work (0-1 slides) Optionally give problems this research opens up. Backup Slides (0-3 slides)
Optionally have a few slides ready (not counted in your talk total) to answer expected questions. (Likely question areas: ideas glossed over, shortcomings of methods or results, and future work.)
What is a good paper presentation?
Shoulders of giants... what previous research does this work build on? What are the
key underlying theoretical ideas? Software infrastructure? Impact
has this work been influential? When later research papers cite it, what contribution is being referred to?
Discussion points End with questions which you think should arise
Presentation Skills It is harder to ask a sensible question than to supply a sensible answer.
(Persian proverb) How to handle a Question:
The goal is to communicate. Show that you understand the question. Are you able to repeat the question? You may even need to restate it. Only answer it once you both agree about it. Then you will truly communicate.
Presentation Skills
Conducting the talk Straighten up. Face the audience. Convey that you are happy to be here. Dare to speak slowly and loudly.
Accept that in the end, by giving a talk, you express who you are.
Presentation Skills Recommendations:
be very well prepared, and be ready to have fun and to learn new things.
Also, beware that someone (e.g., your host) might shanghai your talk. Don’t:
overestimate your audience: you probably have spent more time thinking about your problem than most people here;
underestimate your audience: there is always the risk that a world specialist is here.
underestimate yourself: you come from a good university and you are well-prepared;
overestimate yourself: prepare your talk well.
Handling Questions
The golden rule still applies: ALWAYS repeat the question.
It gives you time to identify its nature. Technical question: give a technical answer. Friendly question: use it to make your point even better. Challenging question: be upfront.
How to present a paper (at a conference)
Do unto others as you would have them do unto you
Objectives, in decreasing order of importance Keep people awake and attentive
everything has been tried: play fiddle, cartoons, jokes in most cases, extreme measures should not be needed humor can help
Get the problem definition across people in audience may not be working on your problem
How to present a paper (at a conference)
Objectives … in decreasing order of importance
Explain your general approach most productive use of your time
Dirty details most people in the audience probably do not care a typical conference includes 30+ paper presentations,
yours could be the N-th
Talk outline or not ?
Useful when several ideas discussed in a single talk
Short talks : Skip the outline
Long talks : Include an outline
Make the outline interesting
Text
You want people to (quickly) read your slides
Use big enough font
Do not put too much on one slide don’t want to keep them busy reading, instead of listening
Use good color schemes Not blue on yellow
Text
Slide text need not be grammatically accurate
Keep it short OK to omit some details fill them in when you present the paper
Practice makes perfect versus
Practice can improve your presentations
PowerPoint, but not excessively
Everybody has used PowerPoint
No one is impressed by fancy backgrounds anymore
Avoid using gratuitous animation
Standard PowerPoint layouts can be useful decent font sizes and color schemes
Picture is worth 1000 words
Use illustrations to explain complex algorithms
Omit minor details, focus on the important
They can read the paper to know the exact algorithm
Short talks
May not have enough time to discuss all ideas clearly
Focus talk on one or two ideas
Summarize rest briefly
Better to explain one idea well, than many ideas poorly
How to present a paper
Avoid blocking the screen Point to the screen, rather than the slide on the projector Practice makes perfect (or tolerable) May need several trials to fit your talk to available time
particularly if you are not an experienced speaker
How many slides?
Depends on personal style Rules of thumb
1 slides for 1-2 minutes Know your pace
I tend to make more slides than I might need, and skip the not-so-important ones dynamically
Anticipate technical questions, and prepare explanatory slides
If English is your second language
Accent may not be easy to understand
Talk slowly
Easier said than done I have a tough time slowing down myself
No substitute for experience
Nothing like a terrible presentation to learn what not to do
Try to learn from other people’s mistakes, instead of waiting for your own
