M: And what about the overhead projector? Do you think I should use it?
W: Well, yes, you do. Carefully prepared overhead projector transparencies will make you feel more confident and will help your audience to understand the points you’re making. Any visual aids you use will interest the audience and will provide some welcome variety to your presentation. Perhaps you could take something else with you to illustrate your talk too.
M: I’ll think about that—once I’ve made up my mind about what I’m going to talk about! What about the talk itself? Any tips there?
W: Well, it’s difficult when you don’t know what you’ve going to talk about yet but I suppose some things are relevant whatever the subject. Make sure you get off to a good start. Outline for your audience what you’re planning to talk about. Also try to say something interesting or amusing or striking in some way at the very outset so that you capture their attention at the start. Then it’s almost as important to finish on a high with a clear and memorable conclusion. In other words, remember that first and last impressions are particularly significant.
M: And what about the middle?
W: Well, the middle part of what you say can take care of itself in a way. Just remember make the structure and point of what you’re saying obvious to the audience. Don’t be afraid to rephrase and summaries your main points to make sure you get them across. But make it enjoyable for the audience too by being amusing, if appropriate, or by, perhaps, illustrating points you make with an anecdote or an analogy. Something that is too abstract and theoretical can be a bit tedious to listen to for too long. Anyway we can discuss that more when you’ve got your subject chosen.
M: Yes, when I’m a bit more prepared would you listen to me having a go at it and give me more advice?
W: Course, I will. Oh, it’d be great if you get that job!
