How to: Expository Presentations


The purpose of an expository presentation is to explain, clarify or define an object, an idea, a social institution or a process. The key to giving a successful expository presentation is to fully prepare yourself. By engaging in thorough preparation, you will become an expert on the topic you are presenting and will be able to share that knowledge. The task will take a lot of hard work and time.

Consider the audience you will be presenting to. If the topic of your presentation is monetary policy, you would give a different presentation to a group of economics professors than you would to a high school class. You will need to gather information appropriate to the audience you a presenting to. You don't want to bore them with information they already know or confuse them with information inappropriate for their level of expertise.

Research your topic thoroughly. In order to effectively present your topic, you must have a clear understanding of what it is you're presenting. You will also need evidence to back up the points that you will make during the presentation. Take notes while you conduct research.

Organize your presentation. Your presentation should include an introduction, a body and a conclusion. The introduction should grab the audience's attention and tell them why the topic your presenting is important. In the body, show the reasons why the topic is important. The body should have contain your key points and data or evidence to back them up. The conclusion should summarize the information you've presented.

Practice. As the saying goes, "practice makes perfect." Perform the presentation in front of a mirror. Rehearse what you're going to say and how. Ask friends or family members to sit for a trial presentation and to critique it. Make changes as necessary, but get comfortable with what you're going to say.
