The success of an oral presentation lies in the speaker’s ability to transmit information to the audience. Lucia Hartigan and colleagues describe what they have learnt about delivering an effective scientific oral presentation from their own experiences, and their mistakes

The objective of an oral presentation is to portray large amounts of often complex information in a clear, bite sized fashion. Although some of the success lies in the content, the rest lies in the speaker’s skills in transmitting the information to the audience. 1

Preparation

It is important to be as well prepared as possible. Look at the venue in person, and find out the time allowed for your presentation and for questions, and the size of the audience and their backgrounds, which will allow the presentation to be pitched at the appropriate level.

See what the ambience and temperature are like and check that the format of your presentation is compatible with the available computer. This is particularly important when embedding videos. Before you begin, look at the video on stand-by and make sure the lights are dimmed and the speakers are functioning.

For visual aids, Microsoft PowerPoint or Apple Mac Keynote programmes are usual, although Prezi is increasing in popularity. Save the presentation on a USB stick, with email or cloud storage backup to avoid last minute disasters.

When preparing the presentation, start with an opening slide containing the title of the study, your name, and the date. Begin by addressing and thanking the audience and the organisation that has invited you to speak. Typically, the format includes background, study aims, methodology, results, strengths and weaknesses of the study, and conclusions.

If the study takes a lecturing format, consider including “any questions?” on a slide before you conclude, which will allow the audience to remember the take home messages. Ideally, the audience should remember three of the main points from the presentation. 2

Have a maximum of four short points per slide. If you can display something as a diagram, video, or a graph, use this instead of text and talk around it.

Animation is available in both Microsoft PowerPoint and the Apple Mac Keynote programme, and its use in presentations has been demonstrated to assist in the retention and recall of facts. 3 Do not overuse it, though, as it could make you appear unprofessional. If you show a video or diagram don’t just sit back—use a laser pointer to explain what is happening.

Rehearse your presentation in front of at least one person. Request feedback and amend accordingly. If possible, practise in the venue itself so things will not be unfamiliar on the day. If you appear comfortable, the audience will feel comfortable. Ask colleagues and seniors what questions they would ask and prepare responses to these questions.

It is important to dress appropriately, stand up straight, and project your voice towards the back of the room. Practise using a microphone, or any other presentation aids, in advance. If you don’t have your own presenting style, think of the style of inspirational scientific speakers you have seen and imitate it.

Try to present slides at the rate of around one slide a minute. If you talk too much, you will lose your audience’s attention. The slides or videos should be an adjunct to your presentation, so do not hide behind them, and be proud of the work you are presenting. You should avoid reading the wording on the slides, but instead talk around the content on them.

Maintain eye contact with the audience and remember to smile and pause after each comment, giving your nerves time to settle. Speak slowly and concisely, highlighting key points.

Do not assume that the audience is completely familiar with the topic you are passionate about, but don’t patronise them either. Use every presentation as an opportunity to teach, even your seniors. The information you are presenting may be new to them, but it is always important to know your audience’s background. You can then ensure you do not patronise world experts.

To maintain the audience’s attention, vary the tone and inflection of your voice. If appropriate, use humour, though you should run any comments or jokes past others beforehand and make sure they are culturally appropriate. Check every now and again that the audience is following and offer them the opportunity to ask questions.

Finishing up is the most important part, as this is when you send your take home message with the audience. Slow down, even though time is important at this stage. Conclude with the three key points from the study and leave the slide up for a further few seconds. Do not ramble on. Give the audience a chance to digest the presentation. Conclude by acknowledging those who assisted you in the study, and thank the audience and organisation. If you are presenting in North America, it is usual practice to conclude with an image of the team. If you wish to show references, insert a text box on the appropriate slide with the primary author, year, and paper, although this is not always required.

Answering questions can often feel like the most daunting part, but don’t look upon this as negative. Assume that the audience has listened and is interested in your research. Listen carefully, and if you are unsure about what someone is saying, ask for the question to be rephrased. Thank the audience member for asking the question and keep responses brief and concise. If you are unsure of the answer you can say that the questioner has raised an interesting point that you will have to investigate further. Have someone in the audience who will write down the questions for you, and remember that this is effectively free peer review.

Be proud of your achievements and try to do justice to the work that you and the rest of your group have done. You deserve to be up on that stage, so show off what you have achieved.

Steps to Plan Your Presentation

Instructor teach a class full of students on How to Make an Oral Presentation

Delivering an effective oral presentation is an essential skill for sharing your research findings with an audience. Tailoring your presentation to your audience, preparing for technical issues, and engaging your listeners with clear, concise content are crucial for the success of your research project. This guide provides comprehensive advice on how to prepare, what to include, and common pitfalls to avoid, ensuring your presentation is impactful and memorable.

For further assistance, contact the Office of Undergraduate Research for individual consultations.

What You Need To Know

Purpose

The purpose of an oral presentation is to share your research with an audience, typically through PowerPoint or Prezi. It is typically a synopsis of your research. If you've conducted a study, you will probably address the following topics:

Background research on your topic (with citations to past studies)
The rationale for your study (how does your study address a gap in the literature?)
Hypotheses/research questions
Methodology
Results (graphs are more interesting than tables or words)
Conclusions (for example, the implications or applications of your research, limitations, future research directions, a concise summary of your main findings, concluding thoughts)
References and Acknowledgements (such as grant support, a faculty advisor if he/she is not an author on the presentation, assistance from others who are not listed as authors)

If your scholarship is in a different form (e.g., a film analysis, a presentation of a creative work), the structure will likely be a little different, but in all cases, it should be clear to the audience what the main goals of your research are, why it's important to do this work, and what you found in your research.

Preparation

First, make sure you know how much time you have; it is common for oral presentations at conferences to exceed the time limit. Prepare a presentation that is a little shorter than the allotted time to allow for questions and other comments.
Think about your audience: Will they understand technical terms, jargon, and acronyms? Will they be mostly undergraduates or professors in the field? You should tailor your presentation to your expected audience.
Think carefully about your central message. What do you want the audience to know by the end of your presentation? Most people will only remember a few take-home points from your carefully constructed presentation (if that!). There's no point in getting bogged down in minutia that the audience can't really process anyway.
The most important parts are the beginning (to draw the audience in) and the ending (to wrap up, to inspire). Put some thought into how to make these parts of your presentation have impact.
Think about your speaking style; can you speak loudly and clearly? Can you modulate your voice appropriately, or do you tend to sound monotone when you give presentations? Consider working on your public speaking skills if it's needed; consider joining Legacy Owls Toastmasters Club for this purpose and check out Toastmasters International public speaking tips .

Plan for the Unexpected

Will the conference provide computers or do you bring your own laptop?
Will there be internet available?
How reliable is the internet?
Will there be speakers or a way to use audio (if necessary)?
Back up your presentation in at least two places (e.g., flash drive, Dropbox, email it to yourself).
When you prepare a presentation on a Mac and then use a PC (or vice versa), be aware that sometimes things look different.
Bring a printed copy in case the technology fails, or have a tablet/laptop with you.
Find the room early, and check out the technology so you’re familiar with it.

What to Avoid

It is usually not required that you use visuals for your presentation, but a PowerPoint or Prezi can often help the audience follow along with your research.

If you use PowerPoint or Prezi:

Avoid the temptation to put too much text on your slides; the audience can get bored or overwhelmed and might not be able to clearly see all the words if you've used a small font (less than 20-pt is considered "small").
Avoid font types that are hard to read or look unprofessional.
Avoid putting words on a busy powerpoint background that makes the words hard to read.
Avoid using font color that doesn't contrast with the background (in other words, your audience can't read gray text on a black background).
Avoid tables and graphs that have too much information - you can recreate those tables and graphs with just the most important information instead.

Also, consider your verbal and physical presentation:

Avoid reading your slides to the audience.
Avoid reading from prepared notes; the audience will maintain interest better if you can speak extemporaneously directly to them. It's also hard to make eye contact with the audience if you are reading.
Avoid distracting behaviors or verbal tics (“um,” “like,” “uh”).
Dress appropriately for the occasion.
Consider your body language (e.g., arms crossed can come across as you not wanting to be there).

Ways to Stand Out

Embrace a "Presentation Zen" style: simple (not simplistic), clean, and powerful.
Have interesting, high-resolution images on your slides.
You could connect your research to recent events (perhaps asking the audience to summarize the recent event).
You could ask specific questions throughout the presentation.
You could poll the audience on a topic relevant to your presentation (perhaps even using a free resource such as Socrative or Poll Everywhere ).
You could insert a powerful quote into your presentation (perhaps at the beginning or end).
You can show a short video to illustrate something important about your topic.
The point is not to be gimmicky; the point is to keep your audience interested and engaged (especially when the audience has been listening to oral presentations all day and might be tired). Be aware, though, that different disciplines have different conventions regarding what is and is not appropriate for an oral presentation; be sure to ask your research advisor for advice first.
Showing enthusiasm for their work
Being energetic
Using emphasis on certain words
Using hand gestures to keep the audience engaged

Handling Audience Questions

Be sure to leave some time at the end.
If a questioner is soft-spoken, repeat the question so everyone hears.
Avoid long, meandering answers.
Don’t make something up if you don’t know an answer. Offer to look it up and get back to the person, and be open to someone in the audience knowing the answer.
Give positive reinforcement to questioners (smiling, nodding, “that’s a good question”).
If someone is attacking you or otherwise being rude, remember that this usually comes from someone who wants to show off or appear smart in front of everyone The other audience members will recognize the rudeness and be on your side! Stay calm, answer as best you can, and acknowledge it when he/she makes a good point (smiling and nodding can disarm an attacker).
People will often talk to you right afterwards; try to avoid running out right after your presentation if you can help it.
Audience members may email for a copy of your presentation or to ask further questions; be sure to follow up with them.

Conclusions

If you have been accepted to present your research at a conference, congratulations! This is a great honor, and you should be proud of this accomplishment.

How to make a scientific presentation

Scientific presentation outlines

Questions to ask yourself before you write your talk, 1. how much time do you have, 2. who will you speak to, 3. what do you want the audience to learn from your talk, step 1: outline your presentation, step 2: plan your presentation slides, step 3: make the presentation slides, slide design, text elements, animations and transitions, step 4: practice your presentation, final thoughts, frequently asked questions about preparing scientific presentations, related articles.

A good scientific presentation achieves three things: you communicate the science clearly, your research leaves a lasting impression on your audience, and you enhance your reputation as a scientist.

But, what is the best way to prepare for a scientific presentation? How do you start writing a talk? What details do you include, and what do you leave out?

It’s tempting to launch into making lots of slides. But, starting with the slides can mean you neglect the narrative of your presentation, resulting in an overly detailed, boring talk.

The key to making an engaging scientific presentation is to prepare the narrative of your talk before beginning to construct your presentation slides. Planning your talk will ensure that you tell a clear, compelling scientific story that will engage the audience.

In this guide, you’ll find everything you need to know to make a good oral scientific presentation, including:

The different types of oral scientific presentations and how they are delivered;
How to outline a scientific presentation;
How to make slides for a scientific presentation.

Our advice results from delving into the literature on writing scientific talks and from our own experiences as scientists in giving and listening to presentations. We provide tips and best practices for giving scientific talks in a separate post.

There are two main types of scientific talks:

Your talk focuses on a single study . Typically, you tell the story of a single scientific paper. This format is common for short talks at contributed sessions in conferences.
Your talk describes multiple studies. You tell the story of multiple scientific papers. It is crucial to have a theme that unites the studies, for example, an overarching question or problem statement, with each study representing specific but different variations of the same theme. Typically, PhD defenses, invited seminars, lectures, or talks for a prospective employer (i.e., “job talks”) fall into this category.

➡️ Learn how to prepare an excellent thesis defense

The length of time you are allotted for your talk will determine whether you will discuss a single study or multiple studies, and which details to include in your story.

The background and interests of your audience will determine the narrative direction of your talk, and what devices you will use to get their attention. Will you be speaking to people specializing in your field, or will the audience also contain people from disciplines other than your own? To reach non-specialists, you will need to discuss the broader implications of your study outside your field.

The needs of the audience will also determine what technical details you will include, and the language you will use. For example, an undergraduate audience will have different needs than an audience of seasoned academics. Students will require a more comprehensive overview of background information and explanations of jargon but will need less technical methodological details.

Your goal is to speak to the majority. But, make your talk accessible to the least knowledgeable person in the room.

This is called the thesis statement, or simply the “take-home message”. Having listened to your talk, what message do you want the audience to take away from your presentation? Describe the main idea in one or two sentences. You want this theme to be present throughout your presentation. Again, the thesis statement will depend on the audience and the type of talk you are giving.

Your thesis statement will drive the narrative for your talk. By deciding the take-home message you want to convince the audience of as a result of listening to your talk, you decide how the story of your talk will flow and how you will navigate its twists and turns. The thesis statement tells you the results you need to show, which subsequently tells you the methods or studies you need to describe, which decides the angle you take in your introduction.

➡️ Learn how to write a thesis statement

The goal of your talk is that the audience leaves afterward with a clear understanding of the key take-away message of your research. To achieve that goal, you need to tell a coherent, logical story that conveys your thesis statement throughout the presentation. You can tell your story through careful preparation of your talk.

Preparation of a scientific presentation involves three separate stages: outlining the scientific narrative, preparing slides, and practicing your delivery. Making the slides of your talk without first planning what you are going to say is inefficient.

Here, we provide a 4 step guide to writing your scientific presentation:

Outline your presentation
Plan your presentation slides
Make the presentation slides
Practice your presentation

4 steps for making a scientific presentation.

Writing an outline helps you consider the key pieces of your talk and how they fit together from the beginning, preventing you from forgetting any important details. It also means you avoid changing the order of your slides multiple times, saving you time.

Plan your talk as discrete sections. In the table below, we describe the sections for a single study talk vs. a talk discussing multiple studies:


Introduction	Introduction - main idea behind all studies
Methods	Methods of study 1
Results	Results of study 1
	Summary (take-home message ) of study 1
	Transition to study 2 (can be a visual of your main idea that return to)
	Brief introduction for study 2
	Methods of study 2
	Results of study 2
	Summary of study 2
	Transition to study 3
	Repeat format until done
Summary	Summary of all studies (return to your main idea)
Conclusion	Conclusion

The following tips apply when writing the outline of a single study talk. You can easily adapt this framework if you are writing a talk discussing multiple studies.

Introduction: Writing the introduction can be the hardest part of writing a talk. And when giving it, it’s the point where you might be at your most nervous. But preparing a good, concise introduction will settle your nerves.

The introduction tells the audience the story of why you studied your topic. A good introduction succinctly achieves four things, in the following order.

It gives a broad perspective on the problem or topic for people in the audience who may be outside your discipline (i.e., it explains the big-picture problem motivating your study).
It describes why you did the study, and why the audience should care.
It gives a brief indication of how your study addressed the problem and provides the necessary background information that the audience needs to understand your work.
It indicates what the audience will learn from the talk, and prepares them for what will come next.

A good introduction not only gives the big picture and motivations behind your study but also concisely sets the stage for what the audience will learn from the talk (e.g., the questions your work answers, and/or the hypotheses that your work tests). The end of the introduction will lead to a natural transition to the methods.

Give a broad perspective on the problem. The easiest way to start with the big picture is to think of a hook for the first slide of your presentation. A hook is an opening that gets the audience’s attention and gets them interested in your story. In science, this might take the form of a why, or a how question, or it could be a statement about a major problem or open question in your field. Other examples of hooks include quotes, short anecdotes, or interesting statistics.

Why should the audience care? Next, decide on the angle you are going to take on your hook that links to the thesis of your talk. In other words, you need to set the context, i.e., explain why the audience should care. For example, you may introduce an observation from nature, a pattern in experimental data, or a theory that you want to test. The audience must understand your motivations for the study.

Supplementary details. Once you have established the hook and angle, you need to include supplementary details to support them. For example, you might state your hypothesis. Then go into previous work and the current state of knowledge. Include citations of these studies. If you need to introduce some technical methodological details, theory, or jargon, do it here.

Conclude your introduction. The motivation for the work and background information should set the stage for the conclusion of the introduction, where you describe the goals of your study, and any hypotheses or predictions. Let the audience know what they are going to learn.

Methods: The audience will use your description of the methods to assess the approach you took in your study and to decide whether your findings are credible. Tell the story of your methods in chronological order. Use visuals to describe your methods as much as possible. If you have equations, make sure to take the time to explain them. Decide what methods to include and how you will show them. You need enough detail so that your audience will understand what you did and therefore can evaluate your approach, but avoid including superfluous details that do not support your main idea. You want to avoid the common mistake of including too much data, as the audience can read the paper(s) later.

Results: This is the evidence you present for your thesis. The audience will use the results to evaluate the support for your main idea. Choose the most important and interesting results—those that support your thesis. You don’t need to present all the results from your study (indeed, you most likely won’t have time to present them all). Break down complex results into digestible pieces, e.g., comparisons over multiple slides (more tips in the next section).

Summary: Summarize your main findings. Displaying your main findings through visuals can be effective. Emphasize the new contributions to scientific knowledge that your work makes.

Conclusion: Complete the circle by relating your conclusions to the big picture topic in your introduction—and your hook, if possible. It’s important to describe any alternative explanations for your findings. You might also speculate on future directions arising from your research. The slides that comprise your conclusion do not need to state “conclusion”. Rather, the concluding slide title should be a declarative sentence linking back to the big picture problem and your main idea.

It’s important to end well by planning a strong closure to your talk, after which you will thank the audience. Your closing statement should relate to your thesis, perhaps by stating it differently or memorably. Avoid ending awkwardly by memorizing your closing sentence.

By now, you have an outline of the story of your talk, which you can use to plan your slides. Your slides should complement and enhance what you will say. Use the following steps to prepare your slides.

Write the slide titles to match your talk outline. These should be clear and informative declarative sentences that succinctly give the main idea of the slide (e.g., don’t use “Methods” as a slide title). Have one major idea per slide. In a YouTube talk on designing effective slides , researcher Michael Alley shows examples of instructive slide titles.
Decide how you will convey the main idea of the slide (e.g., what figures, photographs, equations, statistics, references, or other elements you will need). The body of the slide should support the slide’s main idea.
Under each slide title, outline what you want to say, in bullet points.

In sum, for each slide, prepare a title that summarizes its major idea, a list of visual elements, and a summary of the points you will make. Ensure each slide connects to your thesis. If it doesn’t, then you don’t need the slide.

Slides for scientific presentations have three major components: text (including labels and legends), graphics, and equations. Here, we give tips on how to present each of these components.

Have an informative title slide. Include the names of all coauthors and their affiliations. Include an attractive image relating to your study.
Make the foreground content of your slides “pop” by using an appropriate background. Slides that have white backgrounds with black text work well for small rooms, whereas slides with black backgrounds and white text are suitable for large rooms.
The layout of your slides should be simple. Pay attention to how and where you lay the visual and text elements on each slide. It’s tempting to cram information, but you need lots of empty space. Retain space at the sides and bottom of your slides.
Use sans serif fonts with a font size of at least 20 for text, and up to 40 for slide titles. Citations can be in 14 font and should be included at the bottom of the slide.
Use bold or italics to emphasize words, not underlines or caps. Keep these effects to a minimum.
Use concise text . You don’t need full sentences. Convey the essence of your message in as few words as possible. Write down what you’d like to say, and then shorten it for the slide. Remove unnecessary filler words.
Text blocks should be limited to two lines. This will prevent you from crowding too much information on the slide.
Include names of technical terms in your talk slides, especially if they are not familiar to everyone in the audience.
Proofread your slides. Typos and grammatical errors are distracting for your audience.
Include citations for the hypotheses or observations of other scientists.
Good figures and graphics are essential to sustain audience interest. Use graphics and photographs to show the experiment or study system in action and to explain abstract concepts.
Don’t use figures straight from your paper as they may be too detailed for your talk, and details like axes may be too small. Make new versions if necessary. Make them large enough to be visible from the back of the room.
Use graphs to show your results, not tables. Tables are difficult for your audience to digest! If you must present a table, keep it simple.
Label the axes of graphs and indicate the units. Label important components of graphics and photographs and include captions. Include sources for graphics that are not your own.
Explain all the elements of a graph. This includes the axes, what the colors and markers mean, and patterns in the data.
Use colors in figures and text in a meaningful, not random, way. For example, contrasting colors can be effective for pointing out comparisons and/or differences. Don’t use neon colors or pastels.
Use thick lines in figures, and use color to create contrasts in the figures you present. Don’t use red/green or red/blue combinations, as color-blind audience members can’t distinguish between them.
Arrows or circles can be effective for drawing attention to key details in graphs and equations. Add some text annotations along with them.
Write your summary and conclusion slides using graphics, rather than showing a slide with a list of bullet points. Showing some of your results again can be helpful to remind the audience of your message.
If your talk has equations, take time to explain them. Include text boxes to explain variables and mathematical terms, and put them under each term in the equation.
Combine equations with a graphic that shows the scientific principle, or include a diagram of the mathematical model.
Use animations judiciously. They are helpful to reveal complex ideas gradually, for example, if you need to make a comparison or contrast or to build a complicated argument or figure. For lists, reveal one bullet point at a time. New ideas appearing sequentially will help your audience follow your logic.
Slide transitions should be simple. Silly ones distract from your message.
Decide how you will make the transition as you move from one section of your talk to the next. For example, if you spend time talking through details, provide a summary afterward, especially in a long talk. Another common tactic is to have a “home slide” that you return to multiple times during the talk that reinforces your main idea or message. In her YouTube talk on designing effective scientific presentations , Stanford biologist Susan McConnell suggests using the approach of home slides to build a cohesive narrative.

To deliver a polished presentation, it is essential to practice it. Here are some tips.

For your first run-through, practice alone. Pay attention to your narrative. Does your story flow naturally? Do you know how you will start and end? Are there any awkward transitions? Do animations help you tell your story? Do your slides help to convey what you are saying or are they missing components?
Next, practice in front of your advisor, and/or your peers (e.g., your lab group). Ask someone to time your talk. Take note of their feedback and the questions that they ask you (you might be asked similar questions during your real talk).
Edit your talk, taking into account the feedback you’ve received. Eliminate superfluous slides that don’t contribute to your takeaway message.
Practice as many times as needed to memorize the order of your slides and the key transition points of your talk. However, don’t try to learn your talk word for word. Instead, memorize opening and closing statements, and sentences at key junctures in the presentation. Your presentation should resemble a serious but spontaneous conversation with the audience.
Practicing multiple times also helps you hone the delivery of your talk. While rehearsing, pay attention to your vocal intonations and speed. Make sure to take pauses while you speak, and make eye contact with your imaginary audience.
Make sure your talk finishes within the allotted time, and remember to leave time for questions. Conferences are particularly strict on run time.
Anticipate questions and challenges from the audience, and clarify ambiguities within your slides and/or speech in response.
If you anticipate that you could be asked questions about details but you don’t have time to include them, or they detract from the main message of your talk, you can prepare slides that address these questions and place them after the final slide of your talk.

➡️ More tips for giving scientific presentations

An organized presentation with a clear narrative will help you communicate your ideas effectively, which is essential for engaging your audience and conveying the importance of your work. Taking time to plan and outline your scientific presentation before writing the slides will help you manage your nerves and feel more confident during the presentation, which will improve your overall performance.

A good scientific presentation has an engaging scientific narrative with a memorable take-home message. It has clear, informative slides that enhance what the speaker says. You need to practice your talk many times to ensure you deliver a polished presentation.

First, consider who will attend your presentation, and what you want the audience to learn about your research. Tailor your content to their level of knowledge and interests. Second, create an outline for your presentation, including the key points you want to make and the evidence you will use to support those points. Finally, practice your presentation several times to ensure that it flows smoothly and that you are comfortable with the material.

Prepare an opening that immediately gets the audience’s attention. A common device is a why or a how question, or a statement of a major open problem in your field, but you could also start with a quote, interesting statistic, or case study from your field.

Scientific presentations typically either focus on a single study (e.g., a 15-minute conference presentation) or tell the story of multiple studies (e.g., a PhD defense or 50-minute conference keynote talk). For a single study talk, the structure follows the scientific paper format: Introduction, Methods, Results, Summary, and Conclusion, whereas the format of a talk discussing multiple studies is more complex, but a theme unifies the studies.

Ensure you have one major idea per slide, and convey that idea clearly (through images, equations, statistics, citations, video, etc.). The slide should include a title that summarizes the major point of the slide, should not contain too much text or too many graphics, and color should be used meaningfully.

Effective Oral Presentations

Verbally (and as a general rule), do not write down and memorize or read your full text, because then your presentation will sound like what it is: a recited written text. Instead, memorize the outline of your presentation — that is, a tree structure of main points and subpoints — and speak ex tempore, reinventing the words as you go along. As you do, you will occasionally need to think about what to say next and find the most appropriate words to say it. Instead of using filler words ( um , er , you know , I mean , etc.), simply pause. If you say um , you get about half a second of thinking time and the audience is likely to notice the um and be irritated by it. If you keep silent, you can get up to two or three seconds of thinking time without the audience noticing anything. Even if attendees do notice the silence, they will simply think that you are choosing your words carefully — and there is nothing wrong with that.

Despite pointing often at the screen, Marie nicely faces the audience with her body at all times, keeps her hands down between gestures, and maintains eye contact with the attendees. Transcript Vocally, vary the tone, rate, and volume of your voice as a function of the meaning, complexity, and importance of what you are saying. You need not invent a new intonation pattern: You simply need to amplify your normal pattern.

Visually, control your body. Adopt a stable, confident position; move only when you have a positive reason to do so (for example, move closer to the audience for taking questions), not when your body seems to ask for it. When you make a gesture, make it large and deliberate; between gestures, bring your hands down and do not fidget. Establish eye contact: Engage the audience by looking them straight in the eyes.

At all times, make sure you address the audience. Even if you have slides, tell the audience your story in a stand-alone way; do not just explain your slides. In particular, anticipate your slides. You should know at all times what your next slide is about so you can insert an appropriate transition.

Delivering as a non-native speaker

To keep the audience engaged , Jean-luc emphasizes his points with facial expressions, purposeful gestures, and — especially — a high dynamic range in his vocal delivery. Transcript If you are a non-native speaker of English, you may find it more challenging to speak ex tempore in English than in your native language. Still, even imperfect extemporaneous English is more likely to engage the audience than reciting a more polished, less spontaneous written text. To improve your delivery and overall presentation as a non-native speaker, practice more, pace yourself, and support your spoken discourse with appropriate slides.

While all speakers benefit from practicing their presentations multiple times, consider investing more time in such practice if you are less familiar with the language. Practicing helps you identify missing vocabulary, including key technical terms (which are difficult to circumvent), and express your ideas more fluently. As you practice, you may want to prepare a list of difficult words (to review on the day of your presentation) or write down an occasional complex yet crucial sentence. Still, do not feel bound to what you write down. These notes should be a help, not a constraint.

Practicing in front of an audience (a few colleagues, for example) can help you correct or refine your pronunciation. If you are unsure how to pronounce some words or phrases, you can ask native speakers in advance or check online dictionaries that offer phonetic spelling or audio rendering. Still, you may be unaware of certain words you mispronounce; a practice audience can point these words out to you if you invite it to do so.

During your presentation, pace yourself. As a non-native speaker, you may feel you need to search for your words more often or for a longer time than in your native language, but the mechanism is the same. Do not let this challenge pressure you. Give yourself the time you need to express your ideas clearly. Silence is not your enemy; it is your friend.

Pacing yourself also means speaking more slowly than you otherwise might, especially if you have an accent in English. Accents are common among non-native speakers — and among specific groups of native speakers, too — and they are not a problem as long as they are mild. Often, they are experienced as charming. Still, they take some getting used to. Remember to slow down, especially at the beginning of a presentation, so your audience can get used to your accent, whether native or not.

Handling stage fright and mishaps

Most speakers, even experienced ones, are nervous before or during an oral presentation. Such stage fright is normal and even reassuring: It shows that you care, and you should care if you want to deliver an effective presentation. Accordingly, accept your stage fright rather than feeling guilty about it. Instead of trying to suppress nervousness, strive to focus your nervous energy in your voice, your gestures, and your eye contact. Do not let it dissipate into entropy, such as by using filler words or engaging in nervous mannerisms.

Among the many ways to keep your nerves under control, perhaps the most effective one is to focus constructively on your purpose at all times. Before your presentation, eliminate all the unknowns: Prepare your presentation well, identify (or even meet) your audience, and know the room. During the presentation, do what it takes to get your message across, even if it means doing something differently than you had planned. Have a positive attitude about the presentation at all times: Visualize what you want to achieve, not what you want to avoid.

Even with careful preparation, mishaps can occur. For example, technology may fail, you may forget what you wanted to say, or you may accidentally say the wrong thing. As a rule, do not apologize for what happens — neither in advance nor after the fact. Although well-meant, such apologies provide no benefit to the audience: They are noise. If you can do something about the problem, such as fix the technology or insert what you forgot later in the presentation, concentrate on doing so instead of apologizing. If the problem is out of your control, then there is no need to apologize for it. As a specific example, if you feel your command of English is poor, then do what you can in advance to improve it; in particular, practice your presentation thoroughly. Then, on the day of the presentation, do your best with the command you have, but do not apologize at the beginning of the presentation for what you think is poor English. This apology will not solve anything, and it gives the attendees a negative image of you. Rather, let the attendees judge for themselves whether your command of English is sufficient (perhaps it is, despite what you might think). In other words, focus on delivering results, not excuses.

Delivering an oral presentation in conferences and meetings can seem daunting. However, if delivered effectively, it can be an invaluable opportunity to showcase your work in front of peers as well as receive feedback on your project. In this “How to” article, we demonstrate how one can plan and successfully deliver an engaging oral presentation.

Giving an oral presentation at a scientific conference is an almost inevitable task at some point during your medical career. The prospect of presenting your original work to colleagues and peers, however, may be intimidating, and it can be difficult to know how to approach it. Nonetheless, it is important to remember that although daunting, an oral presentation is one of the best ways to get your work out there, and so should be looked upon as an exciting and invaluable opportunity.

Slide content

Although things may vary slightly depending on the type of research you are presenting, the typical structure is as follows:

Opening slide (title of study, authors, institutions, and date)
Methodology
Discussion (including strengths and weaknesses of the study)

Conclusions

Picking out only the most important findings to include in your presentation is key and will keep it concise and easy to follow. This in turn will keep your viewers engaged, and more likely to understand and remember your presentation.

Psychological analysis of PowerPoint presentations, finds that 8 psychological principles are often violated 1 . One of these was the limited capacity of working memory, which can hold 4 units of information at any 1 time in most circumstances. Hence, too many points or concepts on a slide could be detrimental to the presenter’s desire to give information.

You can also help keep your audience engaged with images, which you can talk around, rather than lots of text. Video can also be useful, for example, a surgical procedure. However, be warned that IT can let you down when you need it most and you need to have a backup plan if the video fails. It’s worth coming to the venue early and testing it and resolving issues beforehand with the AV support staff if speaking at a conference.

Slide design and layout

It is important not to clutter your slides with too much text or too many pictures. An easy way to do this is by using the 5×5 rule. This means using no more than 5 bullet points per slide, with no more than 5 words per bullet point. It is also good to break up the text-heavy slides with ones including diagrams or graphs. This can also help to convey your results in a more visual and easy-to-understand way.

It is best to keep the slide design simple, as busy backgrounds and loud color schemes are distracting. Ensure that you use a uniform font and stick to the same color scheme throughout. As a general rule, a light-colored background with dark-colored text is easier to read than light-colored text on a dark-colored background. If you can use an image instead of text, this is even better.

A systematic review study of expert opinion papers demonstrates several key recommendations on how to effectively deliver medical research presentations 2 . These include:

Keeping your slides simple
Knowing your audience (pitching to the right level)
Making eye contact
Rehearsing the presentation
Do not read from the slides
Limiting the number of lines per slide
Sticking to the allotted time

You should practice your presentation before the conference, making sure that you stick to the allocated time given to you. Oral presentations are usually short (around 8–10 min maximum), and it is, therefore, easy to go under or over time if you have not rehearsed. Aiming to spend around 1 minute per slide is usually a good guide. It is useful to present to your colleagues and seniors, allowing them to ask you questions afterwards so that you can be prepared for the sort of questions you may get asked at the conference. Knowing your research inside out and reading around the subject is advisable, as there may be experts watching you at the conference with more challenging questions! Make sure you re-read your paper the day before, or on the day of the conference to refresh your memory.

It is useful to bring along handouts of your presentation for those who may be interested. Rather than printing out miniature versions of your power point slides, it is better to condense your findings into a brief word document. Not only will this be easier to read, but you will also save a lot of paper by doing this!

Delivering the presentation

Having rehearsed your presentation beforehand, the most important thing to do when you get to the conference is to keep calm and be confident. Remember that you know your own research better than anyone else in the room! Be sure to take some deep breaths and speak at an appropriate pace and volume, making good eye contact with your viewers. If there is a microphone, don’t keep turning away from it as the audience will get frustrated if your voice keeps cutting in and out. Gesturing and using pointers when appropriate can be a really useful tool, and will enable you to emphasize your important findings.

Presenting tips

Do not hide behind the computer. Come out to the center or side and present there.
Maintain eye contact with the audience, especially the judges.
Remember to pause every so often.
Don’t clutter your presentation with verbal noise such as “umm,” “like,” or “so.” You will look more slick if you avoid this.
Rhetorical questions once in a while can be useful in maintaining the audience’s attention.

When reaching the end of your presentation, you should slow down in order to clearly convey your key points. Using phases such as “in summary” and “to conclude” often prompts those who have drifted off slightly during your presentation start paying attention again, so it is a critical time to make sure that your work is understood and remembered. Leaving up your conclusions/summary slide for a short while after stopping speaking will give the audience time to digest the information. Conclude by acknowledging any fellow authors or assistants before thanking the audience for their attention and inviting any questions (as long as you have left sufficient time).

If asked a question, firstly thank the audience member, then repeat what they have asked to the rest of the listeners in case they didn’t hear the first time. Keep your answers short and succinct, and if unsure say that the questioner has raised a good point and that you will have to look into it further. Having someone else in the audience write down the question is useful for this.

The key points to remember when preparing for an oral presentation are:

Keep your slides simple and concise using the 5×5 rule and images.
When appropriate; rehearse timings; prepare answers to questions; speak slowly and use gestures/ pointers where appropriate; make eye contact with the audience; emphasize your key points at the end; make acknowledgments and thank the audience; invite questions and be confident but not arrogant.

Tips for Oral Presentations at Scientific Meetings and Conferences

By Nina Lichtenberg

Tis’ the season for the biennial, annual, or semi-annual life science conference; and this time around, you’re scheduled to give a presentation in front of every known expert in your field of study (yikes!) Your thoughts may range from “I can’t wait to share my shiny new data with a room full of scientists!”, to “Why me?”

Never fear, whether thrilled or terrified, follow these tips below to engage your audience and give a stellar presentation. Please note that the advice below applies to all forms of presentations but is focused on those that take place at scientific meetings or conferences. If you don’t have any presentations scheduled but would like to give one, check out the last section on seeking presentation opportunities.

You have an upcoming conference presentation scheduled, now what?

The first step to giving a talk is creating a presentation. The book Designing Science Presentations by Matt Carter is an excellent visually-oriented guide to designing and delivering presentations, and even offers tips on other forms of science communication, like creating figures for manuscripts. Plus, it’s free to download via your university network (see link here ).

Prior to your presentation, and generally throughout your PhD, it’s a good idea to take notes on presentation organization, style, voice, and audience engagement techniques. As a graduate student, you’ve probably attended dozens of talks – both good and bad. Take notes on what stood out to you and what you thought made each presentation successful (or unsuccessful) at getting the speaker’s story across. What made the talk engaging? Was it the way they introduced their research using a witty, real-life or pop culture example? Perhaps it was the way they paused during transitions between topics to ask if the audience had any questions. Maybe it was simply the speaker’s demeanor, or the font, color, or layout of their slides. Integrate what you learned into your presentation. About 25% of the notes I jot down during talks are about the actual manner in which data are presented.

Practice, practice, practice – but don’t over practice

In the few weeks leading up to your presentation, you may be tempted to practice alone, or maybe even to your beloved, non-judgmental furry friend in the comforts of your own home. As tempting as this may sound, practicing in front of a real human audience is key. It’s important to practice in front of others, professors or your peers, for a few critical reasons: this experience will be the closest to the real deal, allowing you to work on your voice and audience engagement, and importantly, your audience will give you feedback on how to communicate your data. They may point out topics you rushed through and/or give you tips on organization. Work on the timing – one slide (or less) per minute is a fairly universal rule. This is especially important for short data blitz style presentations, which are often strictly limited to just 5 or 10 minutes.

Even if you don’t have an imminent conference presentation scheduled, presenting your work throughout your PhD will well prepare you for future conferences and job talks. At my university there are several opportunities for graduate students to present their recent findings in short (5-20 min) and long (1 hr) formats in seminars open to professors, postdocs, and fellow students. If you prefer an informal audience, practice your talk in lab meeting. Additionally, there are often graduate student led organizations that host informal after-lab meetings exactly for this purpose.

If such resources are not available on your campus or at your institution, create them yourself! Not only will these forums give you the chance to practice your talk, but they may expose you to research topics, presentation styles, and individuals from across disciplines. If you’re short on time, gather a handful of science and/or non-science friends and practice your talk on campus or at home. Practice in front of non-scientists (roommates maybe?) – this will benefit you in the long run. “Talking shop” with those outside of your field will strengthen your skills in communicating your data to a broad audience, which is critical for publishing in high-impact journals, getting grants, and for so much more.

Practice, but don’t over practice. Some scientists, including myself, need to spend the time going through what they plan to say for each slide many times before the talk. But for others, this results in a presentation that sounds too rehearsed and a bit robotic. During the presentation, you may need to deviate from the talk that’s drilled into your head to answer unexpected questions or to speed up if you’re running short on time. Preparing an over-rehearsed talk will make adaptation difficult.

So, practice until you’ve memorized every line, or go over your talk just a few times? Practice until your nerves are calm in front of your mock audience, then quit practicing and brush up on some background knowledge that will help you answer tricky questions from audience members.

Tips for the actual real-life presentation

If you’ve but the time into creating a well-organized presentation and have practiced, even a little bit, you will be fine.

Before the presentation: If you’re speaking as part of a symposium, familiarize yourself with the other speakers (and their research) in the panel and at the conference in general. You don’t want to get caught not recognizing someone important. Upon arriving to the conference venue, check out the room in which you will be giving the presentation so that there are no surprises – make note of where the podium is and the microphone, of course.

During the presentation: Take it slow. This will help calm your nerves or jitters. Pausing for a few seconds after each sentence will help. Speak at an appropriate volume and clearly. Remember to look at your audience members for a majority of the time, and not at your slides or down at the floor! Also, the audience doesn’t know your data as well as you do – don’t be afraid to elaborate a bit or remind them of certain goals of your research, even if a technique or result seems elementary to you.

After the presentation: Take a deep breath (you’re done!) Thank the meeting organizers for the speaking opportunity. If there are any questions from the audience, answer them as best you can. If you don’t have a great answer, it’s not a big deal. Offer to speak with the attendee further after the talk or symposium.

The final tips below may seem obvious, but nonetheless important.

Check your presentation for any errors in spelling, grammar, and file conversion, and make sure it is formatted as requested by the organizer/your contact person (i.e. the dreaded Mac to PC, or vice versa PowerPoint conversion issues)
Dress to impress – you and your data will be well-received if you look put together
Get a good night’s sleep

Getting a speaking opportunity at a conference

The easiest way to find speaking opportunities at conferences is to browse the conference organization’s webpage for calls for abstracts. Typically, a conference organizing committee will ask for an abstract anywhere from 1-6 months prior to a conference. Tip: keep abstract deadlines marked on a calendar!

Word of mouth is powerful. Ask your colleagues and/or other graduate students in your program about conferences they’ve attended, especially more senior students who may have already given talks at a few conferences. Also, don’t be afraid to ask professors if they are organizing any conference symposia. You never know if they’re looking for someone to fill a spot – perhaps your shiny new data would be perfect for what they’re organizing. They may also be able to refer you to their colleagues in charge of organizing other scientific meetings.

Of course, attending a conference requires (many) expenses: abstract submission fees, registration fees, poster printing, flight, hotel – it adds up. Travel awards are excellent resources, especially for graduate students. Typically, travel awards are open to both national and international students and typically cover costs of registration, and often offer a discount (or full coverage) on travel expenses. Travel award deadlines are often different from those of abstract submissions and require a recommendation letter – these details can be found on the conference website.

If you win a travel award, awardees are usually invited to attend professional development workshops and to present their data as a talk at the conference. So, not only does the cover some of your travel expenses, but it gives you an opportunity to present your data – win-win! Don’t forget to put the award (and your talk) on your CV. Tip: outside companies and research foundations, like Hello Bio , offer travel awards to students.

Presenting your research at a conference or meeting is a unique, exciting opportunity. It’s not just a chance to share your newest data with your scientific peers, but a chance to build communication skills and boost self-confidence; thus, benefiting both your career and well-being. So, if a speaking opportunity arises don’t hesitate, jump on it!

Oral Presentations: Tips, Significance, Design, Guidelines & Presentation

1) Know your audience

It is always a good idea to structure your talk so that anyone in the audience can understand what you are presenting. A good scientist should be able to present complex, scientific ideas, no matter how technical, in a simple, easy to follow manner. Complexity is not a necessity, it is an annoyance.

Understand your purpose. This way you can get the point of your talk across appropriately and affectively by catering to your specific audience.

2) Be organized

Whether you are giving a 15 minute talk or a 45 minute talk, make sure you give yourself enough time to deliver all the information you want in a calm manner. Allocate time for questions/answers.
Be able to summarize your presentation in five minutes.
Be concise. Use your space wisely. Use illustrations. Check grammar, spelling, and lay out of each slide.
Keep an outline with you during the presentation; it will help you stay on track.
Prepare back up slides. These will come in handy if a question comes up about a topic that needs further explanation.

3) Presentation

Practice your talk enough so that you have flow, but no so much that you have the entire talk memorized. Memorizing your talk will bore you and your audience, as it will be monotonous.

4) Be professional

Know what you are presenting and be ready to answer question during and after the presentation. Do not answer questions vaguely. A knowledgeable scientist is specific and accurate with his/her information.
Dress up to present with confidence and respect for the audience and the science involved.
Be enthusiastic. Scientific talks can be boring, as often they are full of technical jargon. Be clear and talk simplistically.
Make sure the presentation is visually pleasing. Add pertinent graphics and use fewer words.

5) Be aware of technical problems.

Make sure the format you choose for your presentation is compatible with your style of speech. Also, be prepared for technical disasters just before your talk. Be able to give your talk in another format just in case your first choice (ex: PowerPoint presentation) fails to load.

Significance

Oral presentations are an excellent means of communicating basic science or clinical research. Unlike a poster presentation or a written manuscript, the audience during an oral presentation is more attentive as they are focused on the presenter. For the researcher, this is a rare opportunity to shine! In as few as five minutes, the researcher can convey scientific information and give a years worth work some meaning that can be useful to thousands of people. Of course, this also means that in as little as five minutes, the researcher can cause a great deal of confusion by giving a bad presentation.

Just as is the case with written manuscripts and poster presentations, oral presentations must also communicate research to include all aspects of the scientific method. There are, however, no rules as to what order and which format this should be done in. In order to deliver a successful talk, the presenter should be organized, prepared, and enthusiastic about the research being presented.

Design: A General Guideline

Regardless of whether you choose a PowerPoint presentation or transparencies to deliver your talk, here are some general guidelines to keep in mind when designing your presentation.

1) Title (include authors and affiliations)

2) Introduction (Background, Purpose, Hypothesis)

3) Method (A brief introduction to the methodology without too much technical Jargon)

4) Results (Use graphs/charts/table, Provide an extra slide/transparency with a summary of the results, Explain the results)

5) Conclusions/Discussion (Clear explanation of the results, Clinical implications)

6) Future work (Provide information on where the project is headed)

7) Acknowledgment

Presentation

There some people for whom public speaking is as natural as having a conversation with their friends. Conveniently, however, public speaking is an art that can be perfected with enough practice. Here some things to consider before and during the presentation:

Do not go over the time limit.
Speak clearly and concisely. Be coherent. Do not ramble, play with the pointer, or move around in circles.
Dress appropriately.
Make eye contact.
Make sure that each slide/transparency is not cluttered with too many points and ideas. Graphs, tables, and charts should be clearly labeled and easy to interpret.
Practice your talk, but do not memorize a script.
Be visually and orally interesting.
Answer questions in a calm, non-condescending manner; do not argue with or interrupt the questioner.
Be polite and graceful.
Give a presentation that is focused with one underlying message.

In the social and behavioral sciences, an oral presentation assignment involves an individual student or group of students verbally addressing an audience on a specific research-based topic, often utilizing slides to help audience members understand and retain what they both see and hear. The purpose is to inform, report, and explain the significance of research findings, and your critical analysis of those findings, within a specific period of time, often in the form of a reasoned and persuasive argument. Oral presentations are assigned to assess a student’s ability to organize and communicate relevant information effectively to a particular audience. Giving an oral presentation is considered an important learning skill because the ability to speak persuasively in front of an audience is transferable to most professional workplace settings.

Preparing for Your Oral Presentation

In some classes, writing the research paper is only part of what is required in reporting the results your work. Your professor may also require you to give an oral presentation about your study. Here are some things to think about before you are scheduled to give a presentation.

1. What should I say?

If your professor hasn't explicitly stated what the content of your presentation should focus on, think about what you want to achieve and what you consider to be the most important things that members of the audience should know about your research. Think about the following: Do I want to inform my audience, inspire them to think about my research, or convince them of a particular point of view? These questions will help frame how to approach your presentation topic.

2. Oral communication is different from written communication

Your audience has just one chance to hear your talk; they can't "re-read" your words if they get confused. Focus on being clear, particularly if the audience can't ask questions during the talk. There are two well-known ways to communicate your points effectively, often applied in combination. The first is the K.I.S.S. method [Keep It Simple Stupid]. Focus your presentation on getting two to three key points across. The second approach is to repeat key insights: tell them what you're going to tell them [forecast], tell them [explain], and then tell them what you just told them [summarize].

3. Think about your audience

Yes, you want to demonstrate to your professor that you have conducted a good study. But professors often ask students to give an oral presentation to practice the art of communicating and to learn to speak clearly and audibly about yourself and your research. Questions to think about include: What background knowledge do they have about my topic? Does the audience have any particular interests? How am I going to involve them in my presentation?

4. Create effective notes

If you don't have notes to refer to as you speak, you run the risk of forgetting something important. Also, having no notes increases the chance you'll lose your train of thought and begin relying on reading from the presentation slides. Think about the best ways to create notes that can be easily referred to as you speak. This is important! Nothing is more distracting to an audience than the speaker fumbling around with notes as they try to speak. It gives the impression of being disorganized and unprepared.

NOTE: A good strategy is to have a page of notes for each slide so that the act of referring to a new page helps remind you to move to the next slide. This also creates a natural pause that allows your audience to contemplate what you just presented.

Strategies for creating effective notes for yourself include the following:

Choose a large, readable font [at least 18 point in Ariel ]; avoid using fancy text fonts or cursive text.
Use bold text, underlining, or different-colored text to highlight elements of your speech that you want to emphasize. Don't over do it, though. Only highlight the most important elements of your presentation.
Leave adequate space on your notes to jot down additional thoughts or observations before and during your presentation. This is also helpful when writing down your thoughts in response to a question or to remember a multi-part question [remember to have a pen with you when you give your presentation].
Place a cue in the text of your notes to indicate when to move to the next slide, to click on a link, or to take some other action, such as, linking to a video. If appropriate, include a cue in your notes if there is a point during your presentation when you want the audience to refer to a handout.
Spell out challenging words phonetically and practice saying them ahead of time. This is particularly important for accurately pronouncing people’s names, technical or scientific terminology, words in a foreign language, or any unfamiliar words.

Organizing the Content

In the process of organizing the content of your presentation, begin by thinking about what you want to achieve and how are you going to involve your audience in the presentation.

Brainstorm your topic and write a rough outline. Don’t get carried away—remember you have a limited amount of time for your presentation.
Organize your material and draft what you want to say [see below].
Summarize your draft into key points to write on your presentation slides and/or note cards and/or handout.
Prepare your visual aids.
Rehearse your presentation and practice getting the presentation completed within the time limit given by your professor. Ask a friend to listen and time you.

GENERAL OUTLINE

I. Introduction [may be written last]

Capture your listeners’ attention . Begin with a question, an amusing story, a provocative statement, a personal story, or anything that will engage your audience and make them think. For example, "As a first-gen student, my hardest adjustment to college was the amount of papers I had to write...."
State your purpose . For example, "I’m going to talk about..."; "This morning I want to explain…."
Present an outline of your talk . For example, “I will concentrate on the following points: First of all…Then…This will lead to…And finally…"

II. The Body

Present your main points one by one in a logical order .
Pause at the end of each point . Give people time to take notes, or time to think about what you are saying.
Make it clear when you move to another point . For example, “The next point is that...”; “Of course, we must not forget that...”; “However, it's important to realize that....”
Use clear examples to illustrate your points and/or key findings .
If appropriate, consider using visual aids to make your presentation more interesting [e.g., a map, chart, picture, link to a video, etc.].

III. The Conclusion

Leave your audience with a clear summary of everything that you have covered.
Summarize the main points again . For example, use phrases like: "So, in conclusion..."; "To recap the main issues...," "In summary, it is important to realize...."
Restate the purpose of your talk, and say that you have achieved your aim : "My intention was ..., and it should now be clear that...."
Don't let the talk just fizzle out . Make it obvious that you have reached the end of the presentation.
Thank the audience, and invite questions : "Thank you. Are there any questions?"

NOTE: When asking your audience if anyone has any questions, give people time to contemplate what you have said and to formulate a question. It may seem like an awkward pause to wait ten seconds or so for someone to raise their hand, but it's frustrating to have a question come to mind but be cutoff because the presenter rushed to end the talk.

ANOTHER NOTE: If your last slide includes any contact information or other important information, leave it up long enough to ensure audience members have time to write the information down. Nothing is more frustrating to an audience member than wanting to jot something down, but the presenter closes the slides immediately after finishing.

Delivering Your Presentation

When delivering your presentation, keep in mind the following points to help you remain focused and ensure that everything goes as planned.

Pay Attention to Language!

Keep it simple . The aim is to communicate, not to show off your vocabulary. Using complex words or phrases increases the chance of stumbling over a word and losing your train of thought.
Emphasize the key points . Make sure people realize which are the key points of your study. Repeat them using different phrasing to help the audience remember them.
Check the pronunciation of difficult, unusual, or foreign words beforehand . Keep it simple, but if you have to use unfamiliar words, write them out phonetically in your notes and practice saying them. This is particularly important when pronouncing proper names. Give the definition of words that are unusual or are being used in a particular context [e.g., "By using the term affective response, I am referring to..."].

Use Your Voice to Communicate Clearly

Speak loud enough for everyone in the room to hear you . Projecting your voice may feel uncomfortably loud at first, but if people can't hear you, they won't try to listen. However, moderate your voice if you are talking in front of a microphone.
Speak slowly and clearly . Don’t rush! Speaking fast makes it harder for people to understand you and signals being nervous.
Avoid the use of "fillers." Linguists refer to utterances such as um, ah, you know, and like as fillers. They occur most often during transitions from one idea to another and, if expressed too much, are distracting to an audience. The better you know your presentation, the better you can control these verbal tics.
Vary your voice quality . If you always use the same volume and pitch [for example, all loud, or all soft, or in a monotone] during your presentation, your audience will stop listening. Use a higher pitch and volume in your voice when you begin a new point or when emphasizing the transition to a new point.
Speakers with accents need to slow down [so do most others]. Non-native speakers often speak English faster than we slow-mouthed native speakers, usually because most non-English languages flow more quickly than English. Slowing down helps the audience to comprehend what you are saying.
Slow down for key points . These are also moments in your presentation to consider using body language, such as hand gestures or leaving the podium to point to a slide, to help emphasize key points.
Use pauses . Don't be afraid of short periods of silence. They give you a chance to gather your thoughts, and your audience an opportunity to think about what you've just said.

Also Use Your Body Language to Communicate!

Stand straight and comfortably . Do not slouch or shuffle about. If you appear bored or uninterested in what your talking about, the audience will emulate this as well. Wear something comfortable. This is not the time to wear an itchy wool sweater or new high heel shoes for the first time.
Hold your head up . Look around and make eye contact with people in the audience [or at least pretend to]. Do not just look at your professor or your notes the whole time! Looking up at your your audience brings them into the conversation. If you don't include the audience, they won't listen to you.
When you are talking to your friends, you naturally use your hands, your facial expression, and your body to add to your communication . Do it in your presentation as well. It will make things far more interesting for the audience.
Don't turn your back on the audience and don't fidget! Neither moving around nor standing still is wrong. Practice either to make yourself comfortable. Even when pointing to a slide, don't turn your back; stand at the side and turn your head towards the audience as you speak.
Keep your hands out of your pocket . This is a natural habit when speaking. One hand in your pocket gives the impression of being relaxed, but both hands in pockets looks too casual and should be avoided.

Interact with the Audience

Be aware of how your audience is reacting to your presentation . Are they interested or bored? If they look confused, stop and ask them [e.g., "Is anything I've covered so far unclear?"]. Stop and explain a point again if needed.
Check after highlighting key points to ask if the audience is still with you . "Does that make sense?"; "Is that clear?" Don't do this often during the presentation but, if the audience looks disengaged, interrupting your talk to ask a quick question can re-focus their attention even if no one answers.
Do not apologize for anything . If you believe something will be hard to read or understand, don't use it. If you apologize for feeling awkward and nervous, you'll only succeed in drawing attention to the fact you are feeling awkward and nervous and your audience will begin looking for this, rather than focusing on what you are saying.
Be open to questions . If someone asks a question in the middle of your talk, answer it. If it disrupts your train of thought momentarily, that's ok because your audience will understand. Questions show that the audience is listening with interest and, therefore, should not be regarded as an attack on you, but as a collaborative search for deeper understanding. However, don't engage in an extended conversation with an audience member or the rest of the audience will begin to feel left out. If an audience member persists, kindly tell them that the issue can be addressed after you've completed the rest of your presentation and note to them that their issue may be addressed later in your presentation [it may not be, but at least saying so allows you to move on].
Be ready to get the discussion going after your presentation . Professors often want a brief discussion to take place after a presentation. Just in case nobody has anything to say or no one asks any questions, be prepared to ask your audience some provocative questions or bring up key issues for discussion.

Speaking Tip

Your First Words are Your Most Important Words!

Your introduction should begin with something that grabs the attention of your audience, such as, an interesting statistic, a brief narrative or story, or a bold assertion, and then clearly tell the audience in a well-crafted sentence what you plan to accomplish in your presentation. Your introductory statement should be constructed so as to invite the audience to pay close attention to your message and to give the audience a clear sense of the direction in which you are about to take them.

Lucas, Stephen. The Art of Public Speaking . 12th edition. Boston, MA: McGraw-Hill Higher Education, 2015.

Another Speaking Tip

Talk to Your Audience, Don't Read to Them!

A presentation is not the same as reading a prepared speech or essay. If you read your presentation as if it were an essay, your audience will probably understand very little about what you say and will lose their concentration quickly. Use notes, cue cards, or presentation slides as prompts that highlight key points, and speak to your audience . Include everyone by looking at them and maintaining regular eye-contact [but don't stare or glare at people]. Limit reading text to quotes or to specific points you want to emphasize.
