PowerPoints! A number of students will find it helpful to have a visual aid for their essay - either to illustrate an important quote, image, map, sound clip, movie clip, etc. All of the panel rooms are equipped with the technology required for PowerPoints, as well as an internet connection.
In order to make sure that everyone's presentation is in working order, I think it would be helpful for students to send their presentations to me, before the conference, to make sure that everything in it works just fine.
For students at the U of A already, you can go to one of the campus libraries and run the presentation there to make sure that it works on the campus computers. For international students, send 'em to me!
Keep in mind that you don't have to have a PowerPoint - many people won't need them! It's certainly not a requirement and won't take away from your presentation if you don't have one.
Send any files to me by August 10th: firstname.lastname@example.org.
