For work I sometimes get to go to conferences and see many presentations in a few short days. However, when I go to these presentations I often find that everything I need to know is written on the slides and that I do not need to listen to the speaker to fully understand what is being discussed. When this happens I tend to read ahead on the slide and might potentially miss valuable information that is spoken whilst doing so, as well as getting a bit bored whilst waiting for the next slide to appear. I expect that many of you have also experienced this and when you read about presentation technique you frequently get to hear the phrase ‘death by PowerPoint’ which relates to this phenomenon.
What can you do to avoid this?
It might seem drastic, but the way to avoid this trap is to put significantly less text on your slides. Rather than detailing your objective on a slide you could include a prompt (e.g. ‘What was the objective?’) that you would then talk around, or you could include a figure or table but not your thoughts on the table. This way people will have to listen to what you have to say to be able to fully understand what is being presented. An extreme version of this is the Takahashi method where only a single word or short phrase is on each slide to act as a prompt, forcing the speaker to talk about what they are doing and engage with the audience. The Lessig method is similar.
But what if I forget what I am talking about?
It is better to have notes and to practice your presentation to make it as smooth as possible and have it memorable, rather than having a boring presentation. People will forgive you glancing at your notes to remind yourself of a pertinent point and will feel more engaged. These can be included as slide notes in PowerPoint or written separately as a text document.
Where can I find out more about making my presentations better?
I found the book Presentation Zen: Simple Ideas on Presentation Design and Delivery (Voices That Matter) by Garr Reynolds to be extremely informative, and their is a blog by the author this book that is good. It can be found here.
Also slide:ology: The Art and Science of Creating Great Presentations: The Art and Science of Presentation Design by Nancy Duarte is excellent. There is a free multimedia version of her book Resonate online which is about visual storytelling to improve presentations.
