Which comes first, the idea or the supporting evidence? Here are two approaches to help you decide:
The Didactic Method is where you state your idea first, then show the support, and finally restate the main point. This approach offers the bottom line first, shows the audience how the idea came about, and then reminds the audience about your main idea. It's a good teaching or instructive technique.
With the Inductive Method (also referred to as the method of implication) the supporting points are presented first and then the speaker draws a conclusion from those points. This helps listeners hear evidence that supports the validity of an idea before they tune out. Use this method if you think your audience might initially reject your idea or position without even hearing you out. This alternative is good for persuasive speeches.
The Conclusion: So you've grabbed their attention and provided them with comprehensive information in the body of your speech. Now what? It's time to help your audience cross the finish line. The purpose of the conclusion is to offer a signal that the speech is about to close, provide a summary of the information that was presented in the speech, and leave them with a memorable last impression. These three tasks are extremely important considering that most of your listeners will recall your conclusion first when they think about your speech. That means a simple thank you or that's all for now just won't do.
