Tutorial: Giving Good Presentations and Presentation Practice (This is not a good presentation)
You begin preparing a scientific presentation by analyzing your constraints what they know why they are there audience purpose occasion to inform time room to persuade
To excel in your scientific presentations, you guide your audience up the mountain of your work Appreciating the view * Keeping audience on the path Orienting audience at the start [Alley, 2013]
Slides influence the preparation, delivery, and understanding of a scientific presentation
A key assumption is that slides are needed for that part of the presentation [estevejobs.com]
The scope and depth of a talk are interwoven because only so much time exists to give details Scope Depth unknown
Success involves defining a valuable scope and a satisfying depth Valuable Satisfying unknown
Many scientific talks fail because the scope is too broad Scope Unsatisfying depth
Many scientific talks fail because the depth is too deep Too narrow Overwhelming unknown
Success involves defining a valuable scope and a satisfying depth Scope Valuable Satisfying Depth unknown [Alley, 2013]
An important part of the beginning is selecting an appropriate entry point [TED.com]
A common error in the beginning of scientific talks is to leave the audience behind Atmospheric Mercury Depletion Events (AMDEs) in Polar Regions During Arctic Spring Stuart Apple, Kerry Cho, Dale Gray Environmental Engineering Department 22 October 2011

The first step is to write a sentence headline that states the main message of the slide sentence headline
The second step is to find or create visual evidence that supports the sentence headline visual evidence [Alley, 2013]
A data acquisition system changes the form of the data A digital acquisition system has to sample at a rate fast enough to retain the shape of the analog signal Digital Acquisition System Sampling ● Vibration measured by accelerometer Measurement – Analog voltage produced Device – Sinusoidal shape ● Analog signal converted to digital signal ● Signal sampled at a specific rate ● Rate → high enough to retain analog shape Analog-to-Digital Converter

Treat what you’re going to say and the slides as separate but complementary tools. Spend as much, if not more, time on what you’re going to say and let that guide your slides. ≠

A common error in the endings of scientific talks is to waste the last slide [Alley, 2013]

Some Specific Tips from Ten Secrets to Giving a Good Scientific Talk (Do not make a slide like this) http://www.cgd.ucar.edu/cms/agu/scientific_talk.html 1) Prepare your material carefully and logically. Tell a story. The story should have four parts: (a)Introduction (b) Method (c) Results (d) Conclusion/Summary. • The Introduction should not just be a statement of the problem - but it should indicate your motivation to solve the problem, and you must also motivate the audience to be interested in your problem. • The Method includes your approach and the caveats. • The Results section is a brief summary of your main results. • The Conclusion/Summary section should condense your results and implications. • Good speakers often broaden the Introduction to set the problem within a very wide context. • Good speakers may also add fifth item: Future Research. • There is a crusty old saying among good speakers that describes a presentation from the communication viewpoint: "Tell'em what you are going to tell'em. Tell'em. Then tell'em what you told'em." (It is OK to repeat). 2) Practice your talk. 3) Don't put in too much material. 4) If you have to show an equation - simplify it and talk to it very briefly. 5) Have only a few conclusion points. 6) Talk to the audience not to the screen. Also Check Out: 7) Avoid making distracting sounds. http://eloquentscience.com 8) Polish your graphics. Here is a list of hints for better graphics: • Use large letters (no fonts smaller than 16 pts!!) • Keep the graphic simple. • Use colour. • Use cartoons I think some of the best talks use little cartoons which explain the science. 9) Use humour if possible. A joke or two in your presentation spices things up and relaxes the audience. It emphasises the casual nature of the talk. I am always amazed how even a really lame joke will get a good laugh in a science talk. 10) Be personable in taking questions. • First, repeat the question. • Be honest and humble. • If you don't know the answer then say "I don't know, I will have to look into that. A couple miscellaneous points • Thank you - It is always a good idea to acknowledge people who helped you, and thank the people who invited you to give a talk. • Dress up • Check your viewgraphs before you give the talk. • If you have an electronic presentation - check out the system well before the talk.
