Limiting the scope of a presentation, whether it’s to fit the time limit a speaker has been given or simply to deliver a message as efficiently as possible, is a challenge for all speakers.

To give your students a fun way to practice this essential skill, consider assigning some pecha-kucha presentations. Pecha-kucha is a style of presentation that might be the ultimate in creative constraint: The speaker is limited to 20 image slides, each of which is displayed for exactly 20 seconds before automatically advancing.

PechaKucha Nights, which are open to the public, are now put on in cities all over the world. You can visit for more information on these events or to view some archived presentations.
