Presentation Guidelines

Oral Presentations

All plenary and parallel session presentations are 11 minutes: 9 minutes for the talk and 2 minutes for a question and answer period and 1 minute transition time between speakers. *NOTE: There are shorter presentations for community updates. The speakers for those talks will be notified. There will be a speaker timer in the room which will be programmed accordingly:

  • Green- 9 minutes for the talk
  • Yellow- 2 minutes of questions and answers
  • Red- 1 minute - current speaker exits and next speaker is introduced

Please arrive 45 minutes before the start of your session to load your file on the conference computer. Waiting until the last 5 minutes does not give you time to run through the presentation to make sure everything displays properly. Bring your presentation on a flash drive to load on the MAC conference computer. Label your presentation with your presentation number and last name, i.e. 10 Zhang, for easy retrieval. Make sure presentations are created in a 16:9 format so that images and fonts display correctly. Test your presentation on a MAC or PC, other than your own, to insure the fonts are standard and components such as moves run properly.

Please note: All plenary presenters in Royce Hall must send their presentation to 24 hours in advance of their presentation.

Standard equipment provided in each plenary, workshop, and platform session room includes an LCD data projector, screen, computer, lectern, pointer, and microphone.

Preparing Effective PowerPoint or Keynote Presentations

  1. Presentations should be in 16:9 format.To utilize the full screen, you should create your presentation in "widescreen" format. If you've already made your presentation and do not want to change it, it will still work, however you will have black bars on either side of your slides in the meeting room.
  2. Keep visuals clear and easy to read. Abbreviate your message. SIMPLE graphs, charts and diagrams are much more meaningful to an audience than complex cluttered ones.
  3. Avoid using too many patterns and graphics in one frame.
  4. Use a minimum of words for text and title frames. Five to eight lines per frame and five to seven words per line are the maximum-fewer is better.
  5. Use upper and lower case lettering, which is more legible than all capital letters.
  6. Vary the size of lettering to emphasize headings and subheadings, but avoid using more than three sizes per frame.
  7. Fonts: Use standard platform fonts such as Times New Roman, Arial and Helvetica. An unusual font may not translate. If you use a Windows operating system, you should save your presentation with the font embedded in it. Maintain the same or similar type sized from frame to frame, even if some frames have less copy than others.
  8. Keep all type horizontal, even in charts.
  9. Consider color with care. A dark background with highly contrasting text and graphics is most readable. Cool colors (example: deep blue, turquoise, purple) appear to recede and make white or light colored text more readable. In one study, blue was found to be the most effective background color for projection. Do not use red for text; it is extremely difficult to read.
  10. Highlight your main point or heading with a dominant color (example: yellow for the heading, white for body text). Avoid the use of intensely bright or saturated colors that compete with the text.
  11. Maintain a consistent color scheme. Use no more than six colors throughout your presentation.
  12. Select backgrounds to enhance your text or graphics. A background that transitions smoothly from lighter to darker shades of the same hue can be effective. Some software packages permit the gradation from one color to another. A textured background can be effective, but it should not detract from or compete with text or images.
  13. Remember the basics of good design: Plan a template. Use colors consistently with light fonts on a dark background. Keep text clear and easy to read.
  14. Practice your talk to be sure it that it doesn't run over 9 minutes. Many attendees go between sessions so it is important for all the talks to keep on time.

Please note: All plenary presenters in Royce Hall must send their presentation to 24 hours in advance of their presentation.

If a presenter is unable to attend their poster at the designated time, GSA asks that they find an alternate person to present in their absence.

You must be wearing your official meeting badge to gain entry to the exhibits and posters.

Poster Presentations

Invite Poster Viewers

Deadline: June 5, 2019

Amplify your work and seek expert feedback by inviting specific scientists to attend your poster presentation.

  • Undergraduate student, graduate student, and postdoctoral GSA members may invite up to three scientists to attend their poster.
  • You may invite faculty, industry researchers, or fellow early career researchers, but we suggest inviting individuals who typically attend this meeting or who are located in the same city as the meeting.
  • Please note that GSA cannot guarantee meeting attendance of any particular person.
  • GSA will reach out to these scientists and invite them to attend the meeting and your poster.
  • Your abstract and contact details will be included in the invitation.

Preparing Effective Posters

Tips for ensuring your poster presentation is effective:

  • PLAN: An effective poster requires careful thought and preparation. It is not sufficient to enlarge an abstract and add a few figures. First identify your one, two, or three principal messages. Then work out the most effective way to convey those points and choose a headline to help highlight each message. Your poster should be self-explanatory so that you are free to answer questions and expand on particular points.
  • TEXT: Your poster text should be easily readable and the design well organized. Use a type size that can be read easily at a distance. Text that is too small is the most common problem in poster design. Keep the text succinct.
  • GRAPHICS: Summarize current research with clear and self-explanatory graphics: charts, tables, micrographs, diagrams etc. Simple use of color can add emphasis.
  • TITLE: Prepare a heading at the top of your poster indicating the abstract title, authors, and affiliations. Make the title large enough to be read easily from a reasonable distance (~ 4 feet). Authors may opt to include a picture of themselves to allow people to find them to discuss their work after the day of their presentation.
  • METHODS: Details of methodology should be brief and placed at the end of the legend.
  • CONCLUSION: Many successful posters provide a bullet list of conclusions and questions raised.
  • REFERENCES: Some references should be provided, but they need not be as extensive as those in papers.

GSA cannot be responsible for items left in the poster session, including but not limited to poster tubes, purses, backpacks, etc. Please keep personal items with you at all times.
