I hear, I forget I see, I remember I do, I understand (Edwards and Mercer) Visual perception contributes to about 90% to all human learning. Maximum attention span of an adult learner is 20 min Source :

To increase the effectiveness of the teaching To hold the attention span of the learner for the duration of instruction To save time

It is a Medium It MEDIATES

Choice of Medium APPROPRIATE not just AVAILABLE

Practice with equipment Slides should be concurrent with verbal content Pause to allow audience to redirect attention Talk to audience/don’t read slides Explain graphics Use verbal cues for next slide

Total number of slides = 1/2 number of minutes in presentation One topic per slide 3-7 bullets/slide Key words 32 point for text/ 40 point for headings

this font is way too small don’t try to put too much on one slide don’t have to apologize there is just too much here to read and what is here is too small to see, anyway can you even tell which color is which on the bar graph? I can’t because they are too similar.

Use “special effects” sparingly They rarely add anything to the presentation And can be extremely annoying and distracting!

funky fonts are distracting and hard to read this is a sans serif font (Arial) this is a serif font

too small is hard to see, and this is smaller that the minimum resolvable acuity for most of the audience beyond minimum resolvable acuity make big enough to see easily

titles - 40 to 72 pt text - 28 to 40 pt NEVER smaller than 28 pt

ALL CAPS IS NOT VERY READABLE FOR LONG PASSAGES; AVOID THIS EXCEPT FOR SHORT TITLES AND ABBREVIATIONS Sentence case is much more readable!

This passage is more difficult for you to read because it is centered, instead of left justified. Don’t do this. This passage is left justified and easier for you to read. Do this.

chromatic aberration of the eye causes different colors in the slide to appear to be at different depths; and makes it hard to read don’t do it!

This section has lower contrast than what comes next and is harder to read Do this. White on black is easy to see. That’s why it is used in low vision apps.

all the stuff distracts you from my message and the picture you are having trouble seeing this keep it simple

not distracting text easier to read

Imagine the heart to be like a hose with a one-way valve in it.

a small hole If a heart murmur sounds softer may indicate that the hole is larger. a large hole.
