APA stands for American Psychological Association, and it is a common format for citing sources in social sciences, education, and psychology. To cite sources in a speech outline using APA format, you need to include the author's last name, the year of publication, and the page number (if applicable) in parentheses after the sentence that uses the source. For instance, Smith (2020) states that public speaking anxiety is a common problem among students (p. 15), while Jones (2019) argues that persuasive speeches should appeal to both logic and emotion (p. 25). If you use the same source multiple times in your speech outline, you do not need to repeat the year of publication; for example, Smith (2020) also suggests some strategies to overcome public speaking anxiety, such as breathing exercises, positive affirmations, and practice (p. 18), and Jones (2019) provides some examples of persuasive techniques, such as rhetorical questions, anecdotes, and statistics (p. 30). At the end of your speech outline, you need to include a reference list that contains the full details of the sources you cited. This list should be alphabetized by the author's last name and follow the APA style guidelines; for instance, Jones, A. (2019). The art of persuasion: How to craft effective speeches. New York, NY: Penguin, and Smith, B. (2020). Public speaking for beginners: A guide to overcoming anxiety and improving your skills. Boston, MA: Harvard University Press.
