Spatial organization can be used for descriptive and definition speeches. Sarah is preparing her speech, "Defining the Constitution." Her topic has many parts, and she wants to focus on some more than others. She decides that beginning her speech with an overview of the whole document will help the audience understand how it fits together and give importance to each of its elements. Sarah begins her speech by drawing a large diagram of the United States government on the board. This visual aid helps her audience understand the relationship between the different branches of government and allows them to see the overall structure of her speech material. She then goes on to discuss each part of the constitution separately, starting with its preamble and ending with its conclusion. At the end of her speech, she returns to the diagram to summarize all that she has said. This method works well for a speech where the speaker needs to cover a lot of ground. It's also good if you want to include examples or stories from cases that relate to each part of your topic. In addition to being useful for presentations, the diagram method can also be used in papers, reports, and even interviews. For example, you might use it when asking questions about what has been said in order to make sure you have covered everything.
