Know your audience, relax, structure it well, and leave the jargon at home
Why practise communication?
Whether you are applying for funding, telling a family member about your research or engaging the public, your success will depend on how well you communicate.
Persuading people that your research should be prioritised and funded relies on being a solid negotiator and developing political nous; but these skills are also rooted in communication.
One way to do this is by challenging yourself to summarise your research in a short, sharp, three-minute elevator pitch, or ‘flash talk’.
What is a flash talk?
A flash talk is a challenge in which you have just three minutes to present a scientific concept or idea in an accessible manner. They are aimed at non-specialist audiences and usually happen in front of a live audience or a group of colleagues. There are lots of competitions for flash talks that you can get involved in, such as FameLab and Three Minute Thesis.
By convention people don’t use PowerPoint; all you have is the stage, your voice, and perhaps a prop or two to liven up the presentation.
In those three minutes, your aim is to inspire the listener and help them to learn about the area of science that you are presenting. There are a number of ways to do this effectively.
The following are my top ten tips for delivering a flash talk that is clear, concise and charismatic. See if you can spot some of these features in the videos included in this guide.
SciDev.Net joined researchers from across Latin America at a Partnerships for Enhanced Engagement in Research (PEER) event, run by USAID’s US Global Development Lab. Researchers from this programme participated in a short flash talk competition in March to develop their science communication skills. In this video, Djuke Veldhuis identifies the key features of an outstanding flash talk, using footage from the PEER forum in Lima as examples.
Know your audience
| Ask yourself questions about your audience | Who are you talking to? Where are they from? What is their professional background? Do all members of your audience have the same background? How much do they already know? Research your audience, and tailor your talk to their interests and understanding. |
| Be aware of cultural sensitivities and traditions | Discussing abortion in a country where it is outlawed on a religious basis will be met differently than in a non-religious setting. Similarly, a group of vegans may react differently to a discussion about animal research than a group of medical students. |
| Observe your audience while giving your talk | React to them. Are they laughing and engaged, or yawning and looking bored? If they seem uninterested or unhappy, can you modify how you are speaking to get a better reaction? |
Perfect your starting and ending | |
|---|---|
| Learn your starting lines | The pressure of getting on a stage and getting ready to speak to a group of strangers can be daunting. Don’t memorise your whole talk, but know your starting lines so you can start in a clear and confident manner. |
| Place ‘stepping stones’ | Create three or four key stepping stones or check points that you can use to progress through your talk. These might be places where you introduce a new idea or move to a different time or location in your story. |
| Craft the ending | Endings such as “That’s it, thank you” or “I’m out of time” can seem sloppy. Try to have a couple of lines memorised which broadly summarise your talk. That way, if you get cut off or time runs out, your talk appears complete. |
| Round it off | A good way to finish your talk can be to come back to a starting question or statement. For example: “And so the evidence is clear: solar panels are the answer to our impending energy crisis.” A strong message like this will naturally indicate the end of your talk and remind the audience about your objective or key message. |
Make it relevant and relatable | |
|---|---|
How is your research relevant to the audience? People will be more interested in your talk if you’ve made it relatable.
|
|
| Human interest | Make your audience care by bringing out how your research impacts on people. You can reference a person’s story or use a powerful quote. Example: This story from SciDev.Net asks local women from Colquencha, Bolivia, how food security initiatives have affected them. |
| Application | Perhaps you can give specific examples of how your research will be used in a real, tangible way in the future. Example: This story from SciDev.Net explains how big data will help coffee farmers adapt their practices in response to climate change. |
| Involve the senses | Your talk will be more relatable if you can involve the audience’s senses or daily experiences. Tactics include giving an inanimate object a personality or feelings, or describing what it is like to touch, feel, hear and smell something or to be somewhere. Example: Asking the audience to rub their hands together to explain how friction generates heat, or talking through particle physics by visualising the movement of particles in the preparation of a cup of tea. |
Bring elements in from stories | |
|---|---|
Think of your favourite film or book. How do they captivate you? Stories are enormously powerful and introducing some of their elements into your talk can make it more effective. |
|
| Characters | Characters in stories give your audience more to relate to or care about. Your audience will want to know what happens to the character. |
| A crisis or dilemma | You can present opposing views in a debate — ideas that contrast with each other. Such oppositions can create surprise or suspense. If you can offer a resolution to the tension or opposition, your talk will be more memorable. |
| Structuring your talk like a story | This is a highly effective way to communicate in a clear, structured manner. It also allows you to be more dynamic and flexible by, for example, allowing you to include recent news stories or new data if you change your story slightly. |
It's your stage, so don't hide | |
|---|---|
| The stage is yours | By commanding the space in which you are speaking you will appear more assertive, which increases your confidence. |
| Use the whole stage | Moving around the stage allows you to involve the whole audience (for example, those sitting at the sides) and makes them feel more engaged. |
| Get closer | You can move to the front of the stage, addressing the audience as if you are telling them a secret. This will have a greater impact than if you stand locked in the same position for your entire talk. |
| Don’t hide | Avoid ending up behind physical barriers, a costume or even a loud voice. It might feel safer to stand behind a lectern, hide behind paper notes or stand at the back of the stage behind a ‘wall’ of empty space. But these all create a barrier between you and the audience, and hinder effective communication. |
Use your body language wisely | |
|---|---|
| Match your body language to the content | Your talk will lack impact if you are talking about the biggest volcanic explosion in human history by speaking quietly with your arms across your chest and eyes staring at the floor. In this instance moving your arms and opening up your body while moving across the stage will do more to reinforce your message. |
| Express emotions | Humans are pattern recognition machines; if you act surprised by something you are speaking about, the audience are likely to mirror your emotion. This will make them more receptive to your words and ideas, and strengthen your point. |
Avoid distractions | |
|---|---|
| Ensure your audience is focused solely on you and the content | One way to achieve this is to avoid fiddling with keys in your pocket, the microphone cable or rocking nervously on your feet. |
| Remove other distracting habits | These can be physical or verbal (for example, repetitive word use, such as “uhm”, “like”, “literally” or “so”) or waving your hands excessively. If possible, record yourself when practicing to identify habits, or simply ask friends or family to spot them. |
- Before your talk
- After your talk
Avoid jargon and speed bumps | |
|---|---|
| Don’t alienate your audience with technical language | You will lose your audience instantly if you fill your talk with highly specific technical terms normally used only between experts in your field. Only do so if absolutely necessary. For example, use: Best instead of optimum Make clear instead of elucidate Part instead of proportion In a test tube instead of in vitro It was tested on a mouse instead of mouse model Mixing of genetic material instead of hybridisation |
| Explain technical terms or complex concepts | Your audience likes to be challenged and learn something new. Complex concepts or new terminology may temporarily cause your audience to hit the equivalent of a ‘speed bump’. It takes time for them to digest complex information. You can help them by pausing after introducing a complex piece of information and reiterating it clearly by, for example, using an analogy such as: “cells are like the building blocks of life.” |
Use your voice | |
|---|---|
| Plan how you will say it | Your voice is a powerful tool. You can modify lots of aspects of your speech: pitch (high/low), intonation (variation in pitch indicating emotion and attitudes, or the difference between a statement and a question), pace (fast/slow), volume (loud/soft) and emphasis. Using these will ensure you avoid a monotone delivery. |
| Use the active voice | Present your talk in an active voice (Juliet loves Romeo) rather than passive voice (Romeo is loved by Juliet). The active voice is often easier to understand, clearer and fits well with content structured as a story. |
Use a prop | |
|---|---|
| Using a prop or object can help | A prop can be anything from an enlarged model of a molecule or classic science demo to an object, animal or piece of technology relevant to your talk. This might help make it more memorable. a) Make sure the object is large enough to be seen by the whole audience, if not use a hand-held camera and screen to show it. b) Only use a prop if it adds to your talk, not as a gimmick. c) Cover or hide the prop when not in use, otherwise your audience might be distracted by it while you want them to be listening to you. Having it covered before using it might add suspense. |
Final piece of advice
I hope you will find the above points useful, but this advice can only get you so far. As Fergus McAuliffe, FameLab 2014 winner points out: “It’s all about good honest practice and honest feedback.”
My advice is to run your talk by a family member or close friend with no specialist background in the topic — people who will give you frank advice about how understandable and engaging it is.
