Public Speaking Public Speaking PrimerPrimer

Carnegie, Dale, The Quick and Easy Way to Effective Speaking, 1962


Acquiring Basic Skills Take heart from experience of others Keep your goal before you Predetermine your mind to success Seize every opportunity to practice

• Never memorize• Assemble your ideas beforehand• Rehearse with your friends

Predetermine your mind to success Act confident (Fake it ‘till you make it)


Speaking Effectively Speak about something you’ve earned

the right to speak about Be sure you’re excited about your

subject Be eager to share with your listeners


Earning the right to talk Limit your subject Develop reserve power Fill your talk with illustrations and

examples Use concrete, familiar words that create

pictures

Act in earnest


Sharing with the Audience Talk in terms of your listeners’ interests Identify yourself with the audience Make your audience a partner in your

talk Play yourself down


Making a talk to inform Restrict your subject to fit in the time at your

disposal Arrange your ideas in sequence

• Someone’s got to sweat - better you than them

Enumerate your points as you make them Compare the strange with the familiar

USE VISUAL AIDS


Delivering the effective talk Crash through self-consciousness Don’t imitate others - be yourself Converse with your audience Put your heart into your speaking Practice making your voice

Strong and Flexible


Where to go from here Get serious about speaking Recognize its importance Earn the right to be up front speaking,

and realize it Practice, Practice, Practice Use tools


Part III

Technical Speaking Technical Speaking PrimerPrimer

Garland, James, “Advice to beginning physics and engineering

speakers,”Geophysics, the leading edge of exploration, October, 1992, pp. 50-52


You are presenting yourself Present your ideas

• clearly, persuasively

• with self-assurance and skill

Come across as reasonable, orderly person


Gauge your audience Don’t talk to just the experts

• Alienate and annoy your audience

Devote 1/2 to 2/3 of talk to careful introduction • Set up your work/problem clearly

Save highly technical material for last Summarize at the end


Fit your talk to the allotted time Come across as an egotistical S.O.B. Short time limits do notnot mean:

• generalities only

• gloss over specifics

Short time limits mean:• weed out extraneous material

• carefully select the scope of your talk


Use techno-babble sparingly Equations, schematics make talks

• hard to follow

• easy to loose your audience

• slow, ineffective in delivery

Techno-babble only that which is absolutelyabsolutely necessary


Be sensible about visuals Expect to spend 2-3 minutes PER

SLIDE• Audience needs time to absorb material

Don’t write full sentences Don’t write meaningless lists of words Manage your technology seamlessly

• show up early and practice


Practice your talk Rehearse in front of colleagues Get good criticism Tune your delivery, visuals, transitions

• find those hard-to-verbalize ideas

• smooth them out

Avoid writing out your talk, nervous mannerisms


Dress appropriately Button your fly Look like you deserve to be up there Don’t draw attention to yourself - and

away from your talk


Interact with your audience Make eye contact, speak up Ask for, handle questions

• Let your questioner finish the question

• Rephrase the question if necessary

• KEEP YOUR ANSWERS SHORT

• Confess your ignorance

• Deflect hostile questions


In Summary Work hard to make your presentation

clear, well-focused and understandable Let your work speak for you Be in earnest Practice
