Beyond PowerPoint

Chris Francese No Comments

I think my favorite session at the recent Visual Learning conference at Carleton was the one on presentation and pedagogical modes. Despite its obvious utility, all of us who teach or give talks feel slightly oppressed by PowerPoint. Edward Tufte’s famous critique of PowerPoint as contributing to the Challenger disaster is extreme, but we all suffer, I think, from a twin PowerPoint dread: on the one hand, it seems to drive us to a mechanical, deadening style of speaking (“next slide please; as you can see from the outline . . .”); on the other hand, the desire not to be boring makes us want to use all the bells and whistles PowerPoint provides. The less said about those the better.

But how are we to escape? The folks at Viz conference had some ideas.
Robert Smythe of Temple University introduced a Japanese presentation mode known as Pecha Kucha, which was new to me. It uses PowerPoint as a base, but with the following limiting rules: you are allowed 20 slides, which show for exactly 20 seconds each. These slides do not contain text (though there may be photographs that include some text). You, the speaker, talk for the 6’40” available as the slides roll by. That’s it, very basic: “no nuts, no chocolate sauce, no whipped cream,” as Robert put it.

20 seconds gives the audience time to think, to absorb an image, to contemplate. But the slides move you along, and the speaker can’t ramble. It was invented, apparently, by Japanese architects who found that when people are passionate about a project they tend to go on to long. Robert emphasized that this is not so much for teachers as for students giving research presentations. Robert has his students work without script, without notes: just narrate the show.

The crucial beauty of this system is what it does to the speaker. Unlike PowerPoint, which brings out the bureaucrat in all of us, Pecha Kucha allows for an idiosyncratic voice to emerge, and encourages storytelling. Images are rich with implications. Pecha Kucha forces us to interpret them, to fill in the blanks. There are no fades, no transitions, not rotating flying text, just images that drive us to connect them and make sense out of them. The emerging sense is deeply personal, and results in a much more genuine connection between speaker and audience. The example that Robert played for us from his own class, a research assignment about post-war Europe, bore this out nicely. The speaker was almost giddy in communicating her research by explicating the images.

Robert does five per semester, so the students get gradually better at this rather strange type of communication. I have always said that college curricula way under-emphasize public speaking. Here is a way for students to find their own voices at the podium at a much younger age than most of us do. And they best part: it’s fun. People have been known to organize Pecha Kucha nights as entertainment.

Tamara Carley, a PhD candidate in Environmental Sciences at Vanderbilt University, gave a fascinating demonstration of the pedagogical uses of Prezi. After a geology lecture, students are asked to go out and find images to illustrate the main concepts (they can also use professor-supplied charts, etc.), then put it all with their notes into a Prezi canvass that shows the relationships between the concepts and details as the student understands it. It’s a blank canvass. The only requirement is that the composition needs to make sense to the student, and the student needs to be able to explain why it makes sense.

Prezi has a zooming feature that makes it handle differences of scale beautifully. You can zoom back to see the mega level (say, a whole art movement for instance), the macro level (a particular artist), and the micro level (a single work). The student receives new information and works it into their own “mind map” with various levels, and including all sorts of verbal, graphic, and video elements as needed. As it gets more and more elaborate, the composition is evaluated three times per semester, and ends up being in lieu of a final paper. In Tamara’s case this would traditionally be on a single mineral. With this format the final project can be on a broader variety of things, while still having substantial amounts of detail if you drill down.

Here again, the students use presentation technology to create their own meaning and organization out of given facts, not simply repackage what others are saying. Both Pecha Kucha and Prezi used in this fashion pretty much require than the student invest the material with his or her own voice and perspective, a good which seems well worth the trouble of adjusting routines to accommodate these new techniques.

What if you want to just use traditional PowerPoint, but do it well? Doug Foxgrover, Carleton’s Communication and Training Coordinator, gave a diverting history of presentation technology, based partly on Nancy Duarte’s history of visual aides, Slide:ology. He brought along as props a 1920s vintage lantern projector with some very cool glass slides, and an overhead projector. He gave a hilariously bad PowerPoint presentation, which he offers in his classes and asks the students to critique. Ideally, he argued (echoing keynoter Scott McCloud), you want to show and tell at the same time. Foxgrover’s laws of PowerPoint are three in number: 1. Text must be readable–and not much of it, please. 2. Show only what you want others to see. 3. Time your visuals to complement your talk. His laws of graphic design for PowerPoint were also three: 1. Make your objects as simple as possible, but not simpler. 2. Use contrast to draw attention, alignment of text to not draw attention. 3. Choose legible type for the screen.

All in all a fascinating panel. Thanks to all three presenters, and to the sponsors of the conference!

Comics and Visual Communication: Scott McCloud at Carleton Viz Conference

Chris Francese one comments

Comic artist and theorist Scott McCloud, author of Understanding Comics: The Invisible Art (1993), spoke at the recent conference Visual Learning: Transforming the Liberal Arts, at Carleton College in Northfield, Minnesota.

Of the many fascinating points in his keynote speech about the techniques of visual communication and learning, one was a critique of the way presentation software is commonly used, with outline slides that statically reproduce a series of points that a speaker is making. McCloud’s active principal, brilliantly put into practice in his own show, is synchronization: “When I’m telling you, I’m showing you. When I’m done telling you, I’m not showing you anymore.” Cognitive load time, the time it takes to “get” what you are looking at, is very quick, and continuing to display words or images long after their moment has past is deadening. Wordy, over-dense slides, he points out, are a legacy of print culture. The mind is quick, predisposed to fill in gaps, to create meaning and narrative from small, disparate pieces of visual information. This means that “visual rhetoric” can be very powerful. But we have not as yet figured out how that visual rhetoric can best be employed. This is one area he plans to explore in his future work.

McCloud wants to figure out how to use visual culture, including comics but also the whole history of visual culture back to ancient Egyptian tomb paintings, Roman triumphal columns, and medieval stained glass windows, to try create the visual rhetoric of the web. His main interest is finding a way to make comics work effectively on the web, and he had many fascinating examples of innovative and effective web-based comics. His sense of joyous experimentation in search of the right use of the medium was very inspiring to me as I work on finding ways to use the web to enhance classical commentary.

One of his interesting observations regarding comics is that comic strips–3 or 4 panels– have transferred quite well to the web, but that long form graphic novels (think Persepolis and Maus) have not. In his view this is because people have an in-built desire for immersion, to lose themselves in fictional worlds, and that this is simply not readily possible on a computer screen. Books allow us that immersion, that forgetting of the medium known as the proscenium arch phenomenon, in a way that screens do not.

Speaking of computer screens, McCloud was full of scorn for the preservation of upright rectangles of traditional comic pages in the digital realm. The sideways rectangle, wider than it is tall, is the more natural shape, based on the geometry of our two eyes. Theater stages and movie screens are shaped this way, as is the open print book—comics and web designers are foolish to ignore this, he says.

Another key point, and one quite relevant to the DCC, it seems to me, had to do with the relationship between text and image. “Form and content,” he said, “must never apologize for one another.” That is, to create an effective visual narrative, you have to believe both in the message and in the form. You can’t dress up a boring or lame content by adding pretty visuals, or it will just fall flat. By the same token, you shouldn’t simply add illustrations to a great text, because they will seem like afterthoughts, appendages. When creating graphic novels of existing stories the best ones (he singled out City of Glass, based on a Paul Auster story) are true adaptations that honor the potentialities both of visual art, and of the word. As we come to think at DCC of ways to use the visual to enhance the comprehension and enjoyment of Latin and Greek texts, all these reflections are highly relevant.

One more super cool idea I picked up: it is believed that there are six and only six primary facial expressions that express emotions across cultures: joy, surprise, fear, sadness, disgust, and anger. These can be combined: anger + joy = cruelty. A nifty piece of software called The Grimace Project allows the schematic mixing of these, a primitive analogue to the comic artist’s craft. Love, McCloud believes, is best conveyed by using a mixture of joy, surprise, and about 10% sadness–recognition that as wonderful as the emotion is, it is destined not to last. The Grimace Project, by the way, has been helpful to children on the Asperger’s specturm in learning about the visual expression of emotion and social cues.

McCloud’s 2005 TED talk may give you a flavor of what a treat it was to listen to him. Thank, Carleton (and the Mellon Foundation), for sponsoring a truly great conference. Future posts will provide details on some of the regular sessions.
