What I Learned in the Great Presentations Class
“As a PhD student, I feel a lot of pressure to sound smart. When I present, usually in the setting of group meetings, but also in formal presentations such as those we practiced in Great Presentations, I feel a lot of pressure to come off as a productive researcher. This is evident in the tons of stuff I try to fit in my talks. While I have had no talks that went overtime, the truth is I had always prepared more content than I delivered. My urge to tell more—wanting to give more background on robots, wanting to show every visual to convey the complexity of my chip design—stems from the uncertainty that my output passes muster for the field I’m entering.
“I’ve put in so much work! Surely everything I did is worth telling about,” I think to myself when planning my talks, “If I made any of this seem simpler than it is, my audience may confuse my work for an easy project.” Leaving out any detail and every bug I encountered would be such disservice to the hours poured into making progress.
The pressure to give dense talks is also due to an impression I get from being an audience in other presentations, those given by professors and more senior students. As a PhD student still learning the arcane language of my field, I often find it hard to understand talks by more established researchers, and when I do understand, the efforts that went into the research always seem herculean.
As a result of these pressures, I feel I aim to impress (and possibly to beg approval) rather than to communicate when I am on the stage. When I am pressed for time to hit all the points I planned, my mind becomes singularly focused on powering through the content; my story gets muddled, I forget to breathe, and “um”s, “so”s, “I think”s break out. Being rushed is also bad for my body language: I break connection with the audience, I cease to interact with my visuals, and I stare at my own visuals.
Committing to giving a good presentation, especially one that communicates rather than merely dazzles the audience with myriad details, and in particular one that fits in the talk’s time limits, requires courage. Crafting such a presentation requires omitting the details in the research that were often the hardest parts to overcome. The presenter has to be confident the research is sound even when parts have to be left out.
Having a well-timed presentation gives the audience the chance to absorb the story, and it gives the presenter valuable time and a clear head to be aware of the talk’s delivery. Among all the feedback I got from the Great Presentations class, this advice to exercise restraint while planning talks is the most important, since it affects so many other aspects of presenting.
The other major finding I had in Great Presentations is about practicing and improvising.
Now that I frequently speak about my own research, I’ve come to understand presentations as assemblages of many smaller talks. Oftentimes, presentations are ad-hoc: I may be describing my research as part of a conversation, or I may be put on the spot at a meeting. In every setting, the time allocation and level to which my audience is up to speed varies, so I change the way I assemble my mini talks accordingly. However, while the overall speeches are tailored, the mini talks are often well practiced and get carried over between presentations.
The hazard of endlessly repeating segments of old talks is a failure to consider whether the mini talks are up to date. As my research progresses, my mini talks should obviously change as well. Furthermore, while giving a familiar talk is comforting for me, I may have failed to consider better ways to describe my research.
Question-answer interactions during talks help break the cycle of repeating old ideas. Audience questions taught me as the presenter what ideas are not getting across. I noticed I often resort to rehearsed answers: I start back at the beginning in attempt to tell the full story. Instead, I should aim for depth in my answers. If the question asker didn’t nail the question, guide her to ask the deeper question. Answers to good questions are the best chance to fill in the details that had been left out, and they are the precursors to mini talks to include in the future presentations.
Giving great presentations takes time, certainly more time than simply throwing together PowerPoint slides and winging through the talk on stage. But expending time to prepare great presentations is worthwhile.
We admire researchers who adeptly communicate their work. Deciding what details to include and what to leave out—to attempt presenting new ideas in untried talk segments, or to resort to familiar spiels—these decisions are the heart of the art of giving great presentations.”
