Lightning Talk

A lightning talk is a form of short presentation usually with a limited number of slides and a fixed amount of time the speaker has to present each slide.

The most popular form of lightning talk is PechaKucha that uses 20 visual slides with a 20s time limit per slide. You can build a whole lesson around asking students to prepare and deliver lightning talks on a certain topic.

Powerpoint or other presentation software.

Step 1

Choose a theme that is suitable for a short presentation, ideally a theme that enables visual storytelling. 

Step 2

Explain the assignment to the students. Specify how many slides (e.g. 20) and how much time per slide they will have (e.g. 20s). Highlight that slides should be minimalistic, containing a simple picture or a maximum of two-three words. You can assign a Lightning talk to individuals or small groups.

Step 3

Collect all presentation slides in advance and set a timer for each slide in the settings, so the slides advance automatically after a given time (e.g. 20s). An explanation of how to do this in powerpoint is included In the Tips & tricks section below. 

Step 4

Organize a presentation class with prepared Lightning talks. You can serve as a moderator introducing each new lightning talk. As the slides will auto-advance, the timing of the session should be simple. 

Step 5

You can follow up a Lightning talk with a short discussion and/or feedback after each presentation.  

Variation 1 - Individual presentation

Instead of hosting sessions of student presentations, you can use it to add a variety to your lecture and teach a new concept, topic, or talk about your research. 

Variation 2 - PechaKucha

Comes originally from Japan and it popularized this form of fast presentation. As mentioned above speakers are asked to prepare 20 visual slides with 20s time to present each, resulting in short 6min 40s engaging presentations. Usually, multiple PechaKucha presentations are shared during one event. 

Variation 3 - Ignite

Is a similar variation to PechaKucha, with the distinction that speakers are given 15s per slide, resulting in presentations lasting 5min.
