People often ask if technical or science-related presentations can be as compelling as presentations covering other less technical topics. Now, not every presentation has earth-shattering, Nobel-Prize winning significance, but I assume if you are talking about your research or current issues in your field, etc. that your words have a benefit for someone else. I assume it is important, otherwise why waste your time and the time of others? And if it is important, then being effective matters. No one ever said that clarity and a connection with the audience were sufficient conditions for an effective talk; we only ever said they were necessary conditions.
Three years ago I gave some advice for people giving technical presentations in this post. The money quote I still believe is from engineer and scientist Dr. Jay H. Lehr in his 1985 article "Let There Be Stoning" (download article in PDF).
— Jay H. Lehr
This week I heard from Naveen Sinha, a graduate student in the School of Engineering and Applied Sciences at Harvard University. He too has noticed three things that the good lectures/presentations share. In his words:
- They have an outline near the beginning of the talk, which they repeat along the way so the audience can become reoriented with the larger-scale structure of the presentation.
- The slides use a full sentence at the top to summarize the key point, or none at all. Shorter titles are rarely effective. I learned about this from "The Craft of Scientific Presentations" and it's been good advice so far.
- The slides are as simple as possible.
Naveen noted the presentation skills of one of his professors Richard Losick and Princeton professor Bonnie Bassler as good examples. "Both seem to focus on telling a story that the audience will remember, rather than simply showing all their data."
TED Talk: Dr. Bonnie Bassler
Naveen's right about Dr. Bassler; she's fantastic. This is an excellent TED talk below. Dr. Bassler is really good at speaking in a very down-to-earth, conversational manner. There is great clarity to her narrative. For example, she often says "The question is then _______" or "So the question is this: _______." Along the way she also answers the two questions we often have as listeners but that too often go unanswered: "So what? and "Why does it matter (to me/us)?" I love her style. She never relies on the confidence monitors (that we can tell) or bullet points (there are none) but instead she moves her eyes naturally around the room, clearly engrossed in what she is explaining but also very much in the moment. She references the screen often but only to illustrate her point. She uses her hands a great deal to explain processes, just as you would in ordinary, natural conversation.
Sample visuals
Dr. Bassler's visuals are quite simple and for the most part they were a good companion to her talk, yet the attention was on her and her descriptions. At times when she was not speaking about something on screen behind her, TED put up her video which gets all the attention back on her. You can do something similar in a classroom or at smaller conferences by placing black slides in between sections or using the B key on your notebook to make the screen black (don't worry: the room will not go dark because you still have the lights on, right?).
Yes, Dr. Bassler is talking to a general audience here, albeit an extraordinarily educated one. But I think this supports the notion that talks on science-related fields can posses both important content and great clarity that connects with an audience.
Specifically, what should I do?
Each presentation case is different. Audiences vary as do presenter personalities. What you actually do will depend on many things. But if you want tips from a scientist on how to give a good talk at a conference, this PDF by Jay H. Lehr (Let There Be Stoning) is still very good advice. Also remember to look for the story of your content. Information alone is not story. Look here for more info on the power of story.

Garr, you made excellent points. I mostly do technical presentations and I now structure them around a dramatic compelling story (not just anecdotes) in which the technology/process/idea plays a key role. Needless to say, the feedback is always fenomenal.

>>Uhm...do u know that the permalink is so strange?
Yes, that is ugly. The first time you save a draft in Typepad I think is takes the permalink from the title. But I forgot to write the title until later. If no title it goes to the body. The body text was just a bunch of filler text (skldjalkdj) until I dumped in the text later. Oh well....

Excellent post. As someone that presents on medical topics repeatedly, it's a challenge to balance off providing adequate data (and making the slides cluttered and busy) without looking like you're over-simplifying (or even worse, making it look like a marketing presentation!).

I think a story is good and one that will touch emotions are even better. (Humour, sadness, empathy) People tend to remember presentations that touched them more then on a logical level.

I started thinking different in my technical (computer science) presentations after reading the Zen book and having "suffered" as attendee in many talks given at academic conferences.
I found that one can always create a story around the context and contribution of your paper. Visuals and moving away from the bullet point style are indeed powerful techniques.
They makes the more amenable for attendees, and for the talker, it should not make any difference whether you have or not the spoken words on the screen. You (should) know your stuff well enough that just the title and the visuals suffice to trigger the content delivery process inside your head.
My two cents, technical presentations can be engaging by using the presentation zen techniques without loosing any degree of credibility. In any case, there is your published paper to dig into the details and your talk should be about giving the key messages of your contribution while advertising your paper and motivate people to read it!
Here is one of my latest attempts towards a more engaging technical talk on network architectures: http://www.dca.fee.unicamp.br/~chesteve/pubs/CPqD-WS-InternetDoFuturo-information-oriented-090416.pdf

I like this line:

I find that I remember presentations where I was engaged and it wasn't mechanical at all or focused solely on powerpoints or other media. Also the Ted presentation of Jill Taylor is very animated and well done.

I do agree, emotions plays a huge rule in captivating the audience into believing your point of view. Stories is a good way to grab attention and emotion

Excellent points.
It's hard to create the drama in a Technical presentation, I struggle every day with that!

Is what is expressed; the intention and the inevitable reaction of the audience what make it so great.

Bonnie is a very good host and very professional with her presatation, i had watched a few of her presentations from tedo.com previously. They were awesome!

Such a great post. When I coach people who are giving technical presentations - I follow a piece of advice I got from Roger Love: Try singing your speech! I just wrote about Love's advice to a scientist in my speaking advice blog sarahgershman.blogspot.com.
It would be great to hear your feedback.

The best tip I ever got was to learn your audience and speak to them at their level of understanding. That and focus on the the results and not so much on the inundating details.

yes very truly said technical presentation can also be very enjoyable if the presentator is prepared enough on how to deliver and the listener is also interested in the subject matter its a two way process afterall
Posted by: Vanities Bathroom | September 06, 2010 at 06:13 PM
technical presentation is very technical and it cant be engaging for the one who does not belong to technical background so it can be better for those technician only
Posted by: modern kids beds | September 16, 2010 at 02:06 PM
When the presentation, it is not in the dark room and the speaker just read the slide like he/she doesn't known the subject. Also the people have an accent in English like me. It is kind hard because some people hate or some like the accent. For the best presentation, it use a darken room so everyone can see the screen better, which makes the screen the focal point the entire time. Just listen what are you speak and also you can use clear pictures and let people imagine and wonder.
