Prepare your materials for the lecture. While it is probably not a good idea to write out the entire presentation word for word, having a basic level of organization for the presentation is essential. Appropriate methods of organization include outlines, note cards or storyboard-type cue cards. Limit the amount of material in your presentation. A good presentation should have one or two main points. More, and you run the risk of having to rush to get everything in.
Practice your presentation. In addition to giving the speech, work with any AV or technology aids you may use during the presentation. This may also require reviewing the venue rules if your visual aids include scientific materials that may cause fire or explosion hazards. Make sure your graphics and visuals are of an appropriate size for the location of the presentation. For example, 14-point font will not be readable on a projector screen in a large lecture hall.
Introduce your concept. Establish the topic, but also be sure to provide an overview of your solution for the problem. Above all, engage the audience; while the problem may seem obvious to you after all your research, you must also convince the audience that the problem is significant for them.
Explain your methods. Tell the audience steps in your research and the progression of the work.
Report your results. This should be a straightforward summary of the results, including the most important points. If your audience is interested in more details, they can ask questions later.
Analyze the information in the discussion section. Explain what the results mean for the present, and for future research possibilities.
Conclude the talk. Give the audience an opportunity to ask questions if time allows, or make yourself available after the talk.
