Some rough guidelines for giving a conference style presentation
An analogy. The process of developing a talk to that of preparing for a backpacking expedition. Plan ahead, review your goals, and plan for emergencies. At some point after you are fully prepared, open the backpack and remove between 1/3 to 1/2 of its contents. Then shoulder the pack and head for the hills - there will be more spring in your step, and it will be easier to recover if you stumble.
Following are descriptions of the types of conference presentations you may do as a graduate student. Presentation types differ among disciplines. For example, those in the humanities typically read their papers aloud at conferences, while social scientists give summary presentations of longer works.
Paper with Respondent. In this type of presentation, a speaker gives a thirty-minute paper. A respondent then gives a fifteen-minute response to the paper. The speaker subsequently gives a fifteen-minute reply to the response.
Panel Presentation. Panel sessions include 3-4 speakers, each of whom talks for 15-20 minutes. Panels may also have a discussant who comments on the papers/presentations individually and as a group.
Roundtable. A roundtable features five or more speakers, each of whom talks for 5-10 minutes.
Workshop. These sessions can vary in length from 90 minutes to one full day. Workshop presenters give short statements before involving the audience in some type of activity.
A typical framework for a 12 min. talk
The talk has an hourglass shape to the structure. Start broad, narrow the focus, then make it broad again at the end.
A. Four to five minute introduction.
1. The mystery, reason for caring, paradox, curiosity.
2. The background.
a) What's been done that's relevant?
b) Limitations of past experiments.
c) How old results raised current questions.
B. The results (about 4 to 5 mins).
1. Experimental design.
2. The experiment.
3. The hypotheses and predictions.
C. Interpretation of results (2 to 4 mins).
1. Explain the important results clearly.
- Avoid or explain jargon.
- Avoid tables whenever possible.
- Never show data you don't discuss.
- Make clear, colorful figures.
D. Conclusions
1. Summarize the results that lead to your conclusions
2. What are the 2 or 3 things that you want the audience to take home and remember?
3. A final statement of wrap-up, bring the results & conclusions back to the big
picture.
Tips and Suggestions
Preparation
This is where you begin to tailor the talk to the situation, and for that reason this stage is very important for a successful presentation. Talk to your host and clarify these points before you spend much preparation time. If the environment and audience are unfamiliar to you, this is a critical stage. You may even want to do a literature search on potential audience members to identify areas of common interest or potential questions which may arise. Begin this stage early - the more lead time you allow yourself, the more time you will have to think up novel approaches to the topic and the more interesting and substantial your presentation will be.
Once you have a general idea of what you want to say, you'll have to decide how to say it. Unlike a conversation or a written document, a talk is a one-shot attempt to make a point. By contrast, a conversation consists of repetitions and clarification's based on questions and immediate feedback, while a written paper allows a reader to puzzle through its contents as often as necessary. It is essential that your talk be well-constructed and tidy, and that your points be presented to the audience both a logical sequence and unambiguously. This all takes a fair amount of preparation. Start early!
- First, learn all you can about your audience and tailor your presentation to them.
- Start preparing far in advance by thinking through what needs to be said. Collect material which may relate to the topic from unusual sources, and sleep on these ideas. The final product will be more fully-developed and interesting.
- Using big letters and a bold pen, write a clear statement of the problem and its importance, and then pin that statement on the wall above your desk Develop this theme into one jargon-free sentence that will catch the attention of the audience. Next, identify the issues you plan to address.
- Arrange these issues in a logical sequence (which may change as you develop the talk). This process is easier if you use index cards to organize your talk, with one idea per card.
- Retention of information by the audience is reduced as a talk proceeds, so if you do want to make a series of points, organize them from the most to the least important. That way, the audience is more likely to remember the important points later. You may even find that the less important points become irrelevant to the focus of the talk as you practice.
- Determine transition elements which will help your audience to follow the link from one issue to the next. These should be logical, and may presented by posing a question, or explaining your own discovery of the link's existence.
- Attempt to identify problems or questions the audience may have and address them in the talk, before the audience has a chance to think of these things themselves.
- Determine which elements would benefit by being presented with visual aids. Spend time working out the best way to present the material. Head on over to the accompanying tutorials for information on presenting material in an effective way using visual aids.
- Remember, the shorter the talk, the more difficult it will be to cover the material clearly and completely. Be strict about including only what is essential information for the presentation, and removing all the non-essential tidbits.
- If you start preparing early, you'll have plenty of time to refine the presentation based on your colleagues' feedback. This is always a useful process.
-
Practice your presentation!!!!
- Practice is the single most important factor contributing to a good presentation. Don't be fooled by people who claim to be able to throw together a talk at a moment's notice. Generally, their talks fall into two categories - talks which are disjointed and awkward, and talks which have had the rough edges removed by numerous prior presentations (i.e., dull and unexciting). Be critical!
- One problem is that you can waste a tremendous amount of time by practicing all the wrong parts of your talk. It is necessary to run through the talk a few times to get an idea of how the talk will flow.
- Yes, that means running through the talk once or twice isn't enough, particularly if the material is new to you. The presentation is important, treat it that way.
- Breath slowly and deeply, and speak from your diaphragm; project your voice. Practice making eye contact with your imaginary audience, but don't single out one.
- Don't procrastinate when you actually are ready to practice. Take two deep breaths, then begin. Avoid looking at your notes when you don't need to do so. Watch your reflection in the mirror as you speak, looking for odd and distracting habits.
- Work at being relaxed. Stand with feet slightly apart and one foot slightly forward to prevent swaying and weight shifts. Hold your notes in one hand, with the other held naturally at your side. This posture will seem awkward, but looks natural and relaxed. Practice it.
- Your words will probably be different each time you practice, but do try to stick to the general outline of your notes. Don't attempt to memorize your text; use your notes only as reference points to keep you on track. Think about the ideas, and your words will follow naturally. Speak slowly and clearly, and use gestures.
- A tape recorder or videotape are the most useful tools for feedback.
- What you say should be readily understandable by the audience.
- Listen carefully to the words you use, not to what you think you are saying. Are these the best words for making your point? Are they unambiguous? Avoid using jargon whenever possible. Watch your speed for meaningless interjections (ah, um, well) or nervous coughs, sighs or pauses.
- Ask a friend or colleague to evaluate your presentation and, if possible, videotape yourself. And use your visual aids!
- Do you have a clear opening and memorable close? Do you back up statements with credible supporting statistics and data? Does your presentation have energy or will it put your audience to sleep? Rework rough or boring sections and eliminate anything irrelevant.
- The proper use of gestures, facial expressions and controlled movements will increase audience attention and add interest to your message. Are any of your gestures distracting?
- Familiarize yourself with the environment of the room in which you will speak. Make sure all the equipment works and that you know how to use it.
- Make sure your visual aids are clear. The content of visual aids should support your points, not confuse the audience. Use large type on all visual aids.
- Arm yourself with all the facts. Thorough research will provide you with accurate data, figures, examples, comparisons and analogies that will strengthen your argument and help persuade your audience.
- Try and visualize your presentation as a whole, your thoughts should follow a logical order with smooth transitions from one idea to the next.
Content
By dividing your presentation into three parts: the introduction, the body and the conclusion, you create a logical pattern of organization that will help your audience understand more quickly and retain the information for a longer period of time.
-
The Introduction Because your opening remarks will set the tone for what is to follow, the introduction deserves special attention. In just the first few minutes your audience will form an opinion of you and your material. Preview your presentation by stating your objective and outlining the key points. As reinforcement, you may also want to project a visual of your agenda. Provide your audience with a good reason to listen by telling them how they will benefit from your information. Be cautious of opening with a joke as they often backfire. If it makes an appropriate point, doesn't offend anyone, and no one in the audience has heard it before, a joke can be an effective icebreaker. Human interest stories are less risky, but also must be appropriate to your subject matter.
-
The Body The body contains the facts, figures and substance of your presentation. Since organization is a key to audience understanding, clearly state each point with explicit transitions from one idea to the next. From time to time, refer to your objective and show how what you said or are bout to say will contribute to your purpose. Do not be afraid to repeat important points as this is necessary for comprehension and retention of your message.
-
The Conclusion Finally, your conclusion should close your presentation on a positive note. Summarize the key points, restate your goals and objectives, and emphasize the benefits to your audience. If you've asked your audience to carry out a specific task, make sure they understand how and when it is to be accomplished. Always finish on schedule.
- For your topic, choose a major theme or question that represents a "thin slice" of the field's current debates. Be on the cutting edge.
- On the first page, locate the question in a body of knowledge/literature. Make the theoretical significance of your ideas clear.
- Have a strong, creative research design. Anticipate possible critiques when setting up your research design.
- Use clear terminology, but use as little specialized terminology as possible.
- Consider the paper a legal brief that makes a persuasive case and fits it into a ongoing dialogue.
- Use a "bullet" conclusion. In the final part of the paper, repeat the question posed, then explain how you addressed the question, and why the question is relevant. End with a statement of the larger implications of your question.
How much material?
- Pre-determining the content in relation to length is always a problem. The magnitude of the task will become more obvious as you begin to practice. Remember that when you make allowances for a new setting and being interrupted by questions, the practice talk will be about 20% faster than the real presentation.
- Two ways people try to reduce the length of a presentation are to speak more quickly and to reduce the number of words used. Both produce a false economy - the practice talk will fit in your time frame, but the final product won't.
- Try the following suggestions to get into a good ballpark range:
- Estimate a rate of about 100 words per minute (slow!)
- Each statement you make will require an average of 12 words
- Each concept will need to be supported by 3 - 4 statements
- That means for a 50 minute talk, you should expect to cover only about 90 concepts. One way to facilitate the process is to develop visual aids which illustrate your points clearly
Presentation (The Moment of Truth)
Keeping these elements in mind as you prepare and practice the presentation will reduce the amount of re-working you'll have to do as it evolves, and will result in a more streamlined and effective end product.
-
Rate: The optimal rate for a scientific talk is about 100 words per minute. Any faster and the audience can't absorb the additional information. Use pauses, and repeat critical information.
-
Opening: The opening should catch the interest and attention of the audience immediately, while avoiding trite filler phrases (Thank you for having me . . .) and technical jargon.
-
Transitions: The link between successive elements of the talk should be planned carefully, smooth, and logical. You should make the relation between successive elements clear to the audience.
-
Conclusion: Summarize the main concepts you've discussed, and how your work relates to issues you've raised. Aim to help your audience achieve high retention of this final information. Signal that the summary is beginning ("In summary, ..."), but don't begin the summary too soon or else the audience will start to leave before you finish!
-
Length: Don't run over! Ever! Shorten your talk by removing details, concepts, and information, not by eliminating words. If it becomes absolutely essential to supply details, supplement your presentation with a handout. Make about 10% more handouts than you think you'll need. Always leave time for a few questions at the end of the talk.
