A sample outline of an informative speech should include the introduction, body and conclusion. The introduction includes the attention getter, statement of purpose and preview. The body includes the main points and sub-points. The conclusion includes a summary statement and concluding remarks.
According to speech professor Lyn Colangelo at Austin Community College, the purpose of giving an informative speech is to give information or share knowledge. Informative speeches teach, instruct, explain, demonstrate or clarify a topic.
According to communication studies professor Sandie Idziak at the University of Texas at Arlington, the informative speech starts with an introduction. The first part is an attention getter that interests the audience in the topic. Next comes the statement of purpose, which states what the speaker is conveying. A preview briefly covers the main points.
In between the introduction, body paragraphs and conclusion, an outline often includes transitions. Body paragraphs include points, sub-points and, possibly, examples. The outline should consist of two or three body paragraphs.
The final portion of the outline consists of the conclusion. The conclusion starts with a summary statement, which summarizes the main points of the speech. The outline ends with concluding remarks. These are meant to provoke continued thought on the topic.
An informative speech outline is conventionally used when delivering a speech in lieu of having the full text written out.
