📞Intro to Public Speaking Unit 7 – Supporting Materials and Arguments

Supporting materials are crucial for creating impactful speeches. They include evidence, examples, and explanations that reinforce main points, enhancing credibility and persuasiveness. From facts and statistics to expert opinions and visual aids, these elements clarify ideas and engage audiences. Effective use of supporting materials involves selecting credible sources, integrating evidence smoothly, and avoiding common pitfalls. Speakers must balance different types of materials, use visual aids effectively, and practice incorporating them into their speeches for a cohesive and compelling presentation.

What Are Supporting Materials?

  • Supporting materials refer to the evidence, examples, and explanations used to reinforce the main points of a speech
  • Help to clarify, illustrate, and substantiate the speaker's arguments and ideas
  • Can include facts, statistics, expert opinions, personal anecdotes, and visual aids
  • Enhance the credibility and persuasiveness of the speech by providing concrete evidence
  • Enable the audience to better understand and relate to the topic being discussed
  • Should be carefully selected to ensure they are relevant, accurate, and appropriate for the audience and purpose of the speech
  • Play a crucial role in making the speech more engaging, memorable, and impactful

Types of Supporting Materials

  • Examples provide specific instances or illustrations to clarify or support a point (case studies, personal experiences, hypothetical scenarios)
  • Statistics offer numerical data to quantify or compare information (percentages, ratios, averages)
  • Testimonies include expert opinions, eyewitness accounts, or personal stories that lend credibility to the argument
  • Analogies draw comparisons between familiar and unfamiliar concepts to help the audience understand complex ideas
  • Definitions explain the meaning of technical terms, jargon, or unfamiliar concepts
  • Audiovisual aids such as images, videos, charts, and graphs can visually reinforce the message and make the speech more engaging
  • Quotations from respected sources can add authority and credibility to the speaker's arguments

Finding Credible Sources

  • Credible sources are essential for providing reliable and trustworthy supporting materials
  • Academic journals, peer-reviewed publications, and reputable news outlets are generally considered credible sources
  • Government websites, industry reports, and expert interviews can also provide valuable information
  • Evaluate the authority, accuracy, objectivity, and currency of the sources before using them in the speech
  • Cross-reference information from multiple sources to ensure consistency and reliability
  • Avoid using sources that are biased, outdated, or lacking in credibility, as they can undermine the persuasiveness of the argument
  • Properly cite all sources used in the speech to maintain academic integrity and allow the audience to verify the information

Integrating Evidence into Your Speech

  • Balance the use of different types of supporting materials to keep the speech varied and engaging
  • Practice integrating evidence into the speech to ensure a natural and seamless delivery

Strengthening Arguments with Data

  • Data, such as statistics and research findings, can provide powerful support for arguments
  • Use data to quantify the extent or impact of an issue, making the argument more concrete and persuasive
  • Present data in a clear and easily understandable format, such as percentages or simple fractions
  • Round off complex numbers to make them more memorable and accessible to the audience
  • Provide the source of the data to establish credibility and allow the audience to verify the information
  • Explain the implications of the data and how it relates to the main argument being made
  • Use data sparingly and strategically to avoid overwhelming the audience with too many numbers
  • Combine data with other types of supporting materials, such as examples or anecdotes, to make the argument more relatable and engaging

Using Visual Aids Effectively

  • Visual aids can enhance the impact and clarity of supporting materials by providing a visual representation of the information
  • Choose visual aids that are appropriate for the content and purpose of the speech (charts, graphs, images, videos)
  • Ensure that visual aids are clear, legible, and easily visible to the entire audience
  • Keep visual aids simple and uncluttered to avoid distracting from the main message
  • Use consistent formatting, such as colors and fonts, to create a cohesive and professional look
  • Integrate visual aids smoothly into the speech, using verbal cues to direct the audience's attention
  • Practice using visual aids during the speech to ensure a smooth and confident delivery
  • Provide handouts or digital copies of visual aids for the audience to refer to after the speech

Common Pitfalls to Avoid

  • Rehearse the speech multiple times, focusing on the smooth integration of evidence and examples
  • Practice using visual aids to ensure they are easily visible and effectively support the main points
  • Time the speech to ensure that the use of supporting materials does not exceed the allotted time
  • Seek feedback from others on the effectiveness and clarity of the supporting materials used
