Some slide formats use a lot of room

The first thing you write is already

1/3 down the page. This means

your most important material is on

the bottom of the slide, which maybe difficult to see.

Choose fonts that are

are too close).

Use a bigger font

A background color can be helpful to emphasize

Before your presentation

Check out the room you will present in

before your presentation (arrive early) View your slides on the computer to

make sure fonts and animation work

correctly

Determine microphone and pointer

availability


43/55

43

Starting your presentation If your name and presentation title have

just been given, dont repeat them

(unless they are incorrect) If you are nervous, memorize your first

two sentences after that, it getseasier.

Adjust your explanation of materialbased on previous presenters (if they

just explained how an MFC works, dontspend much time on it)


44/55

44

Speaking pointers

Look at your audience

Talk to the audience, not the projectorscreen behind you.

Use the laptop screen as your

teleprompter as it is in front of you.

Consider using the mouse as a pointer

instead of a laser pointer so you donthave to turn around


45/55

45

When using a microphone

Keep a constant distance to the podium

microphone If using a mobile microphone, dont

change your voice direction relative to

the location of the microphone

Put the microphone on the side that is

closest to the projector screen


46/55

46

Make the point of your slide clear, sothat the slide is understood even if

the audience has troubleunderstanding your accent

When answering questions

Dont rush into an explanation think

for a few moments. It is okay. If the questions may not be clear to

others, restate the question. This can

also help you to focus on the mainpoints.

Putting slide numbers on your slideshelps people to ask about specific

slidess
