i know you posted this a while ago, but here's my suggestion: dont think of powerpoints as something bad! they are so helpful during presentations because you can look at the screen instead of the people and the people are looking at the screen instead of you! plus, if you put lots of images on the powerpoint, you can ask that they turn the lights off to see them better and for whatever reason, it's much easier to speak while in the dark. also, if there's any way you can engage the audience...like ask them what they think about some part of what you're talking about, then you can respond to what they're saying instead of just reading off a card, which for me is much easier (this isn't true for everybody, i know) - plus, teachers are always impressed when you try and get the other students to participate in your presentation. also, i know this is expensive, but if you can print out a paper copy of your powerpoint to give to everybody in the class, they will be looking at that and not you, which is a relief.
