44. 27 Nov 20072007 Fall AS Seminar Seniors, Learn from my mistakes! Avoid excessive slide animations Use index cards for reference, not reading NEVER USE BLUE ON BLACK Don’t do things that distract from your message (nervous pointer, brushing hair, “ummmm”, “aahhhhh”) “You probably can’t read this in the back (nor in the front of the room)” All figures need units, axis labels, title, legend, reference, etc Avoid a lengthy “Future Work” slide. Test your presentation beforehand, come to practice session on Sunday evening beginning at 5 PM.
