How to determine the parts of a

presentation

How to deliver PowerPoint

presentations

How to design presentation slides

Presentations in engineering

Advantages of presentations

Can make the presentation come alive

Can revise the presentation on the spot

Can use films, slides, and color

Disadvantages of presentations

One chance to say something correctly

One chance to catch the material

Deal with time constraintsCommunicate to multiple

audiences

From Michael Alley’s The Craft of Scientific Writing


The components of a presentation are based on the same principles as the components of written texts

PurposeWhat is the purpose of a progress report?

AudienceWho is the audience for your progress report?

Time

You want to

consider your


How much time do you have?

Never go over time.


The guideline for creating an effective presentation:

Tell ‘em what you’re going to tell ‘em,

Tell ‘em,

Tell ‘em what you told ‘em.


Always tell your audience where your presentation is going.

Think of your slides as notes


Watch out for the following during your presentations

Putting your hands in your pockets

Turning your back to your audience

Trailing off at the end of sentences…

Staring at your professor during your presentation

Looking only at your group of friends

Standing perfectly still Reading from notes, especially

in monotone

Saying “umm,” “well,” “like,” or “uh” throughout your presentation

Looking surprised at the slide that comes next

Having to say, “Hmm, that wasn’t supposed to do that.”

Including group members who aren’t familiar with the presentation

Staring at your notes throughout the entire presentation

Including slides with just lots of text (like this one!)

FEM MODEL WITH PANELS FOR DECK ELEMENTS

Four-node shellelements of deck panel

Eight-node shellelements of topflange of girder

The translational degrees-of-freedom in the x, y, and z-directions were coupled between the corner nodes of the deck panels and the centerline nodes of the top flange. Translation of the flange imposes shear deformations on the deck form system.

Denotes coupling of translational degrees-of-freedom in x, y,and z-direction betweendeck and girder nodes

Your Presentation Here!

Now that we know what slides should look like, let’s talk about how to deliver them!


For timing

Practice your presentation at least once or twice.

For problems with your slides

For professionalism


Communication is about words, as well as inflection and gestures

7% is communicated

through the actual words

you use55% is communicated

non-verbally

38% is communicated through inflection and

vocal quality

From Mahrabian, Psychology Today


It’s not a movie, so don’t make your slides the main focus.

Don’t read from the screen.

Conclusions Our goal is design and fabricate a small wind

turbine directly driven power train. As of now, the team is behind schedule due to

the demand of our client. We are currently over budget by

approximately $2,000 The team believes that we will be finished by

the deadline, Nov 2, 2009

Any Questions?

Summary

• Project is delayed due to ordering process.

• Milestones 1 and 2 are undergoing • Milestone 3, 4, and 5 are expected to be on schedule.

Tips for Effective Presentations

Start designing your presentation early

Practice, practice, practice Speak in a normal tone Do not read from the screen Use clear transitions Repeat your key points Use your body language

• Purpose • Audience • Technical knowledge
