Presider Guidelines

Instructional Video

Please view our instructional video on how to preside over a session, presented by Ben Eggleton, University of Sydney, Australia.  This video will give you a basic overview of best practices for a presider.

Presider Check-In

We ask all presiders to check-in 30 minutes before your session begins to ensure each session has a designated presider. We will have speaker check-in sheets to determine the talks within your session, the order in which they will be given, and the name of the person giving the presentation. These lists are to assist you in running an effective session.

General Guidelines for Presiders

I. Time Management

Remember to introduce yourself as the presider and announce the session. The use of the lavaliere or podium microphone is encouraged and speakers may need your assistance attaching the lavaliere microphone.

The total amount of time allotted for each paper will be listed in the Advance Program.

II. Facilitating Discussion

As a Presider, it is your job to ensure mediation of discussion during the Q&A period for each talk. Use the following guidelines:

1. Solicit questions from the audience.
2. Have questions prepared in case the audience doesn’t have any.
3. Speaker should repeat the audience member’s question so everyone can hear it
4. At the end of the session, wrap up the session and thank the speakers.

More guidelines on successfully presiding over a session.

A 60-minute mechanical timer will be available for your use. We recommend that the timer is set 5 minutes prior to the end of the presentation time in order to provide a warning to wrap up the talk and start the discussion period. Notify the authors of this warning system. It is also important to remind the speaker to repeat the questions asked from the audience.

Maintaining the scheduled timing of papers is very important. In cases where the paper is withdrawn or the speaker does not show, use the time for an extended question period for authors of previously presented papers or call a break. Your Room Monitor/AV Student will be making note of any no-show papers and contacting the Meeting Manager or AV Coordinator. PLEASE DO NOT START TALKS EARLIER THAN THEY ARE SCHEDULED. All requests to modify the program schedule should be directed to the program chair.

IMPORTANT NOTICE: Due to licensing restrictions, the use of music in presentations, including video presentations, is prohibited. If a speaker uses music during his presentation, please inform Meeting Management immediately.
