    Learning Objectives

    After reading this chapter, you should be able to:

    • Combine multiple forms of evidence to support your ideas.

    • Differentiate between the three types of testimony, and know when to use each one.

    • Navigate the library holdings and distinguish between the types of information found in each section.

    • Evaluate source credibility and appropriateness for your speech.

    • Explain plagiarism and implement strategies to avoid it.

    • Apply chapter concepts in review questions and activities.

    In 2010 celebrity chef Jamie Oliver won the Technology Entertainment Design (TED) Prize for his “One Wish to Change the World.” In addition to a monetary award, he was given 18 minutes at the prestigious TED Conference in Long Beach, CA to discuss his wish: “Teach every child about food.” This chef from Essex, England, had only a short window of time to convince an American audience to change their most basic eating habits. To get them to listen he had to catch their attention and demonstrate his credibility. He managed to do both using compelling research. He began by saying, “Sadly, in the next 18 minutes . . . four Americans that are alive will be dead from the food that they eat.” He magnified the problem with a chart showing that many more Americans die from diet related diseases each year than die from other diseases, or even from accidents and murder. Along with the statistics, he offered testimony from people living in the “most unhealthy state in America.” By weaving together multiple forms of research over the course of his brief talk, Oliver crafted a compelling case for a massive shift in the way that Americans teach their children about food.

    Like Oliver, in order to give an effective speech, you will need to offer support for the ideas you present. Finding support necessitates research. Librarians have found that professors and students tend to have very different ideas regarding what it means to conduct research (Sjober & Ahlfeldt, 2010). The wide variety of resources available for conducting research can be overwhelming. However, if you have a clear topic, recognize the purpose of your speech, and understand the audience you will be speaking to, you can limit the number of sources you will need to consult by focusing on the most relevant information. Different types of appeals and evidence are better for different audiences. The best speeches will combine multiple forms of evidence to make the most convincing case possible. This chapter will help you research your speech by combining personal and professional knowledge, library resources, and Internet searches. It will help you to evaluate the sources you find and cite them to avoid plagiarism.
