As you already know, students have to deliver a presentation as part of the ongoing evaluation for this course. So, I want to offer a few tips on how to give a successful talk. First, think carefully about your introduction. It's essential to engage your audience immediately—you can do this by telling a joke or revealing some surprising statistics—because if they're not paying attention at the beginning of your presentation, they certainly won't be with you by the end. Secondly, involve your audience whenever possible—maybe ask them a question and get a show of hands. The more active your listeners are, the more likely they are to enjoy and remember the talk. Thirdly, keep your ideas focused. From the very beginning, present an outline of your talk with the points you are going to cover, and stay on course as you develop your talk, using only relevant examples and anecdotes. Fourthly, use media and visuals only when they enhance your presentation. PowerPoint, for example, can be a powerful tool but only when it is used appropriately. Don't read from your slides as this leaves the audience feeling that you could simply have emailed them the information. Use visuals carefully to exemplify, clarify or structure your explanations. Finally, think carefully about how to end your talk. Always leave a little time for questions, but be prepared to fill any extra time you may have if nobody asks anything. And everybody likes to go home from a talk with something so, if possible, give or send the audience members a related article, your PowerPoint presentation or access to some online forum.
