One more about the Grace Hopper conference! This one’s a critical look at presentations, since I attended a bunch of panels and some speakers were better than others.

The right way

One of the keynote speakers, Duy-Loan T. Le, was a brilliant orator. She held the audience captive. She had no powerpoint, no slides, nothing but a microphone. Her speech reminded me that far too often, presentations of one’s work or ideas are focused on the text and images lit up on the screen. The right way to do it: focus on you, explaining and selling your work. A display is great for diagrams and supporting pictures. It’s a bonus for clarifying points. But that’s all it should be: support. Not the focus.

The wrong way: what not to do & how to fix it

The general approach to presentations these days assumes that the focus is on the slides, not the person talking. Personally, I watch the speaker. I’ll glance over at the screen now and then. If I can’t understand the talk because I’m not reading along on the slides, there’s a serious problem.

1. Never, ever read sentences directly off the slides. If you do, it means you have too much text on your slides. You can read directly from your notes. Your notes should not be posted on your slides.
2. Talk slower than you think you should. Everyone in the audience appreciates an intelligible speaker.
3. Make clean slides, both in terms of amount of content on any one slide and the content’s format. This topic could fill a book; I’ve touched on it before. Use a font large enough for people to read from the back row. Use easy-to-read colors. Don’t cram text and graphics into every empty space. If you’re just going to gloss over a topic, you don’t need paragraphs about it on your slides – particularly when you flip through your slides more quickly than people can read your paragraphs. What’s the point of having so many words if no one is going to read them?
4. Don’t have paragraphs on your slides, period. If I want the novel, I’ll email you for it, thanks. A presentation involves you and it involves you, presenting. I once sat through a presentation in which the speaker used a gimmick of little cartoon fishies with whom she “conversed” and who “helped explain” her topic. The fishies even made noise – yup, she found a garbled, irritating bubbling audio track. Multiple times, she told the audience, “I’ll let my fish friends explain,” and proceeded to stand quietly on the side of the stage as the audio track played. We, as the audience, were expected to sit there reading the slides.
5. Proof-read your slides. At GHC, I saw the phrase “If you don’t, know one else will.”
6. Unless you specifically know your audience will be full of programmers, don’t put huge chunks of Java pseudocode in your slides. Even if you’re giving a talk for an audience that is mostly technical women, your presentation needs to understandable by the non-programmers, at least on a general level. Similarly, if you’re going to include technical details, don’t gloss over them using unexplained technical terminology to “give the flavor,” because all the audience learns is that they don’t know the jargon.
7. Insist on a mobile microphone and/or a laser pointer. Sometimes you don’t have a choice, such as at GHC this year. Tied to a specific location on the stage, you’re unable to gesture at your slides or point to them except in a vague, flailing manner, and unable to be heard unless you’re rigidly standing in one spot. A laser pointer and and a mobile mic add flexibility and allow you to more easily incorporate your slides into your talk.

Tap tap tap. That’s your pencil hitting the edge of your desk, one rhythmic note at a time. The wood of the pencil has a little indent now from all the tapping (unless you use a mechanical pencil), but at least you’re still awake. The kid next to you has been slumped over his notebook for the past half hour. You’re pretty sure he’s snoring. He has every reason to be, though; the professor has a fantastically monotone voice. Bullet point after bullet point, slide after slide. It’s not like you have to pay attention, either–everything the professor is saying is in the lecture notes handed out at the start of class. But you feel obligated to try to stay awake.

Death by Power Point

Is this at all familiar? Most of us, at some point or another, have experienced the ultimate Boring Lecture: A droning, not-quite-loud-enough voice, reading sentences one by one off a set of elaborate PowerPoint slides. The slides look pretty, sure, but fancy formatting can’t overcome the serious lack of anything remotely engaging.

Fortunately, most lecturers aren’t that bad. But as my friend Carolyn points out, a lot of professors still rely too heavily on PowerPoint. The primary instruction, she says, needs to come from the professors, not from the text slopped across their slides.

And it’s true. A lecture is a performance, and Hubert Knoblauch’s (2008) analysis of PowerPoint presentations suggests that the use of PowerPoint serves to amplify the performance aspect. Slides should complement rather than replace the presenter’s speech. They should be used to emphasize points and help explain difficult concepts with diagrams and photos; after all, a separate sheet of lecture notes with all the text of the bullet points can be handed out later. This may sound obvious, but in practice, most of us conform to convention of cluttering up our slides with too many words and too much visual noise.

Keep it simple, stupid

How do we fix this problem and avoid death by PowerPoint? Garr Reynolds recommends a highly minimalist approach (he’s got a handout[pdf] summarizing his suggestions). Instead of lists and summaries, put just a few key words boldly in the middle of the slide. Use large images and diagrams. Turn off the projector entirely when you happen to digress from the slides. Remove excess logos and irrelevant graphics–they’re just visual noise that detract from your message.

It may take some effort to get the hang of the minimalist presentation (I certainly haven’t gotten it down, though I try), and it will certainly take some guts to be the nonconformist who doesn’t use bullet points. One of my professors at the University of Sydney told a story about a student who went minimalist and was marked down as a result: It wasn’t a proper presentation! (The audience, however, said it was one of the best presentations they had seen in a long time.)

A place for everything

That said, bullet points occasionally have their place: e.g., when the goal is to memorize facts (Kinchin & Cabot, 2007). But if the aim is to make links between concepts and gain a deeper understanding of the subject, other methods of presenting information may fare better.

I’ll open up the floor. What tips and tricks do you keep up your sleeve for making a PowerPoint engaging? Do you adhere to minimalism? Obviously, it’s not all about the slides–it’s also about delivery. Feel free to share thoughts on that, too.
