Tips for Giving a Mathematical Talk

            The last thing that most people think about when preparing a talk is the atmosphere of the room and how his/her presentation will be received by the audience.  Here are a few tips that you may wish to consider as you prepare to speak in front of a group.

For everyone:

· Find out as closely as possible the size of the room in which the talk will be given.  Locate a room on campus that is your estimate of the size.

· After careful preparation of the talk, physically practice in a room of comparable size.  Include practicing with any equipment you will use and be aware that a microphone may be needed in some cases.  During a practice run, walk to the back and sides of the room and see if you can read your own writing!

·  Be sure that the organizer knows that you plan to use a blackboard, an overhead, a VCR, a slide projector, a computer or calculator, or any combination of these.  In many cases advance notice is necessary to ensure the facility is appropriate for the equipment.

· A deep breath and a smile immediately beforehand usually helps, too.

For overhead projector users and PowerPoint users:

· Try not to overload your overlays!  One main idea (or picture) per sheet is more than enough.

· Whether you type (or word-process) or hand-make your overlays, be sure the letters are large, with ample space in between.

· Learn how to focus the machine for last minute adjustments if needed.

· Do not stand in line with the projector.  Watch your arms and shoulders too.

Experienced expositors do not grow overnight!
