Brevity is the Soul of PowerPoint

Brevity is the Soul of PowerPoint

At last, a study that proves what you already knew about PowerPoint:

“Slide presentations as speech suppressors: When and why learners miss oral information,”  Christof Wecker, Computers & Education (2012) [abstract]

There’s a nice summary by Eric Horow, but here it is in bullet points:

  • If your slides aren’t brief, you should
  • A)  Speak without them, or
  • B) Put the entire presentation on slides and don’t say a word.

We’ve always liked Guy Kawasaki’s rule of thumb: 10 slides, 20 minutes, 30-point font.

What happens when your slides aren’t concise?
