Know when to STOP talking. Use a timer or the microwave oven clock to time your presentation when preparing it at home. Just as you don’t use unnecessary words in your written paper, you don’t bore your audience with repetitious or unnecessary words in your oral presentation. To end your presentation, summarize your main points in the same way as you normally do in the CONCLUSION of a written paper. Remember, however, that there is a difference between spoken words appropriate for the ear and formally written words intended for reading. Terminate your presentation with an interesting remark or an appropriate punch line. Leave your listeners with a positive impression and a sense of completion. Do not belabor your closing remarks. Thank your audience and sit down.
