Introduction Why is public speaking important? On the job Defending and explaining ideas Others? How is it used in science and engineering? In other words: When/why will you have to give a presentation? Why is it important to become proficient? Do not have to like it to be good at it

5 Parts of Public Speaking 1.Audience 2.Organization, Goal and Information 3.Intro and Con 4.Delivery includes group delivery and transitions 5.Visual Aids set up, design and use “Tracking the Trackers” – Gary Kovacs Video

Intros and Conclusions Presentations have 3 parts Introduction, Body and Conclusion Intro and Conclusion Often overlooked 10-20% of the presentation Measure this in time 20 minute = 1-2 minutes each

Intros and Conclusions Grocery List 2 points 1.Makes intro and conclusion important 2.Burdens the middle of the presentation Primacy-Recency Effect

Intros and Conclusions Purpose 1.Relates to audience Greeting 2.Impacts audience Explains why topic is important Gets attention 3.States goal and previews points Introduction

Intros and Conclusions Purpose 1.Bring audience back 2.Reinforces goal 3.Ends with an impact Consider linking to Intro Primacy-Recency Conclusion How important is the end of a movie?

Visual Aids: Set up, Design & Use What is the purpose of a visual aid? Aid in understanding Make it interesting Others? Set up Be sure equipment is available and ready Ex. sound, projector, files, etc. Be sure it is there and works Credibility issue

Easy to understand Use large enough font 24 or larger Bullet vs. paragraphs High contrast color combo Visual Aids: Set up, Design & Use Design Basics Consistency Simplicity Readability Less is more 4X4 or 6X6 rule Make a style Similar colors and fonts All headings the same

Visual Aids: Set up, Design & Use Using Visual Aids Refer to it Use it as a tool Point out items Avoid too much focus Use notes, rather than the slides Avoid reading from slides or just looking at objects Be sure it is worth it Assess if it helps your audience Find a friend Have someone else run your slides or get a remote

Conclusion Put it All Together Organize your speech into 3-5 points Strong Intro and Conclusion Remember the Delivery Points Use and choose your Visual Aid well

Activity In project groups Discuss questions about presenting Activity Individual Speeches Sign up for speech order Critique every other speaker on given critique sheet We will take a break between groups I need a timer for both groups – any volunteers?
