9.1: Deploying Supporting Materials
9.1.1: Types of Supporting Materials
There are many types of supporting materials, some of which are better suited for logical appeals and some for emotional appeals.
Learning Objective
Discuss the advantages and disadvantages of using different types of supporting materials
Key Points
- Scientific evidence includes all factual information. It is necessary and particularly useful for logical appeals.
- Testimonials, personal experience, intuition, and anecdotal evidence are all great for emotional appeals.
- Non-scientific supporting materials may be useful, but are not necessarily reflective of broader truths.
Key Term
- anecdote
-
An account or story which supports an argument, but which is not supported by scientific or statistical analysis.
There are a number of types of supporting materials, each of which has its own advantages and disadvantages. Not every type of supporting material is useful or effective in every situation, but each has its own niche.
Scientific Evidence
Scientific evidence is evidence which serves to either support or counter a scientific theory or hypothesis. Such evidence is expected to be empirical and in accordance with scientific method. Standards for scientific evidence vary according to the field of inquiry, but the strength of scientific evidence is generally based on the results of statistical analysis and the strength of scientific controls.More broadly, scientific evidence can be any statistic or fact that has been proven to be true through rigorous scientific methods. Facts and figures are necessary for logical appeals .
Scientific Evidence
Statistics are a type of scientific evidence that can bolster arguments.
Personal Experience
Personal experience is the retelling of something that actually happened to the speaker. Personal experience is useful for emotional appeals, but is not always good for more scientific arguments.
Anecdotal Evidence
Anecdotal evidence is evidence from anecdotes (stories). Because of the small sample, there is a larger chance that it may be unreliable due to cherry-picked or otherwise non-representative samples of typical cases. Anecdotal evidence is considered dubious support for a claim; it is accepted only in lieu of more solid evidence. However, it is particularly useful for making emotional appeals.
Intuition
Intuition is the ability to acquire knowledge without inference or the use of reason. Intuition provides us with beliefs that we cannot justify in every case. For this reason, intuition is not a particularly strong supporting material.
Testimonial
A testimonial is when someone speaks on behalf of another idea, product, or person. For example, weight loss commercials often utilize testimonials. The power lies in how convincing the person giving the testimonial is.
9.1.2: Using Supporting Materials
Supporting materials bolster arguments and can make them more persuasive to audience members.
Learning Objective
Identify reasons to use supporting materials and which types of materials are appropriate in a given situation
Key Points
- Scientific evidence is used to prove that a set of facts exist in the world.
- Non-scientific evidence is often used to create emotional connections with the audience, which can make them more receptive to the argument.
- Misused supporting materials can ruin your perceived reliability as a speaker and cause the audience to stop taking your argument seriously.
Key Term
- scientific evidence
-
Empirical, true facts or figures.
Supporting materials are necessary to turn an opinion into a persuasive argument. Being able to say something and have others immediately accept it as truth is a privilege afforded few speakers in few settings. In the vast majority of cases, audiences will not just want to hear the view you are asking them to accept, but also why they should accept it.
Supporting materials come in many different forms, from scientific evidence to personal experiences. Each is useful in different situations, but all are used to cause the audience to stop rejecting your idea as foreign and instead internalize it as truth.
Not all supporting evidence, however, is created equally. For example, scientific evidence is absolutely necessary in settings such as an exam. Appealing to the emotions of the professor is unlikely to yield a positive result, while articulating and analyzing the correct facts is. Scientific evidence is used to prove that a set of facts or conditions is present in the world.
Scientific Evidence
In most subjects, exam questions test the individual’s grasp of empirical evidence (scientific evidence).
In other instances, more experiential evidence will help you connect to the audience on a personal level. Personal experiences and anecdotes are great for establishing an emotional connection with the audience. Being able to connect emotionally helps to mitigate some of the boredom that often accompanies appeals that are just facts.
Using non-scientific evidence comes with some dangers, however. Non-scientific information is not often generalizable. That is, just because there is a story (or series of stories) does not mean that they necessarily represent the broader truth. Some audiences are skeptical of non-scientific supporting materials for this very reason. Using an anecdote of a boat sinking, for example, is unlikely to persuade most audiences that all boats sink. Attempting to use this type of evidence can actually weaken the appeal by decreasing your perceived reliability as a source.
9.1.3: Using Supporting Materials Effectively
Supporting materials are effective only if they help persuade the audience.
Learning Objective
Name elements to be considered when deciding what type of supporting materials to deploy
Key Points
- Regardless of the type of supporting material used, they are effective only if they fulfill the speaker’s burden of proof.
- Supporting materials must exist in order to be used; not all types exist for all arguments.
- The supporting evidence used depends on the idea being supported. Some ideas are more effectively supported by certain types of materials.
- Not all types of supporting materials are effective for every appeal. Speakers should select the materials that make their specific appeal most effective.
- The type of supporting material used also depends on the audience. If the audience cannot comprehend the material, it is not effective.
Key Term
- comprehensible
-
Able to be comprehended; understandable.
Using Supporting Materials Effectively
Supporting materials are the difference between an opinion and a convincing argument. Supporting materials are effective only if they help to persuade the audience. The type of supporting materials that should be deployed depend on the following:
- Available supporting material: not all types of supporting materials exist for all arguments. If there is no evidence, it obviously cannot be used.
- The idea being supported: if you are trying to explain that your favorite ice cream is chocolate, then scientific evidence about the molecular composition of chocolate ice cream is not as effective as personal accounts .
- The type of appeal: emotional and logical appeals tend to be supported by different types of materials. All types of supporting material can be used for emotional appeals, but providing data may not be as effective as providing anecdotes for connecting with the audience. For logical appeals, all types can again be used, though the most effective support is scientific evidence, because it is empirical and true.
- The audience: different audiences respond differently to different types of supporting evidence. It is the speaker’s job to determine what supporting materials will be most comprehensible and effective.
Gathering Evidence
An individual must have enough supporting material (evidence) in order to write a convincing speech.
Regardless of the type of supporting material used, they are effective only if they fulfill the speaker’s burden of proof. If the supporting materials are not delivered in a way that advances that goal, they are not deployed effectively.
For example, if you are speaking in front of a large crowd, and use a chart printed out on a sheet of paper, it doesn’t really matter what the chart says. If the audience cannot see the chart, then it will not be understood or effective. The same goes for other types of supporting materials; they are only effective if they can convince the audience.
9.2: Using Examples
9.2.1: Types of Examples: Brief, Extended, and Hypothetical
Brief, extended, and hypothetical examples can be used to help an audience better understand and relate to key points of a presentation.
Learning Objective
List the three types of examples
Key Points
- Examples include specific situations, problems or stories intended to help communicate a more general idea.
- Brief examples are used to further illustrate a point that may not be immediately obvious to all audience members but is not so complex that is requires a more lengthy example.
- Extended examples are used when a presenter is discussing a more complicated topic that they think their audience may be unfamiliar with.
- A hypothetical example is a fictional example that can be used when a speaker is explaining a complicated topic that makes the most sense when it is put into more realistic or relatable terms.
Key Term
- Hypothetical
-
A fictional situation or proposition used to explain a complicated subject.
There are many types of examples that a presenter can use to help an audience better understand a topic and the key points of a presentation. These include specific situations, problems, or stories intended to help communicate a more general idea. There are three main types of examples: brief, extended, and hypothetical.
Brief Examples
Brief examples are used to further illustrate a point that may not be immediately obvious to all audience members but is not so complex that is requires a more lengthy example. Brief examples can be used by the presenter as an aside or on its own. A presenter may use a brief example in a presentation on politics in explaining the Electoral College. Since many people are familiar with how the Electoral College works, the presenter may just mention that the Electoral College is based on population and a brief example of how it is used to determine an election. In this situation it would not be necessary for a presented to go into a lengthy explanation of the process of the Electoral College since many people are familiar with the process.
Extended Examples
Extended examples are used when a presenter is discussing a more complicated topic that they think their audience may be unfamiliar with. In an extended example a speaker may want to use a chart, graph, or other visual aid to help the audience understand the example. An instance in which an extended example could be used includes a presentation in which a speaker is explaining how the “time value of money” principle works in finance . Since this is a concept that people unfamiliar with finance may not immediately understand, a speaker will want to use an equation and other visual aids to further help the audience understand this principle. An extended example will likely take more time to explain than a brief example and will be about a more complex topic.
Extended Example
An equation is an extended example that’s used as a visual aid to help the audience understand a complicated topic.
Hypothetical Examples
A hypothetical example is a fictional example that can be used when a speaker is explaining a complicated topic that makes the most sense when it is put into more realistic or relatable terms. For instance, if a presenter is discussing statistical probability, instead of explaining probability in terms of equations, it may make more sense for the presenter to make up a hypothetical example. This could be a story about a girl, Annie, picking 10 pieces of candy from a bag of 50 pieces of candy in which half are blue and half are red and then determining Annie’s probability of pulling out 10 total pieces of red candy. A hypothetical example helps the audience to better visualize a topic and relate to the point of the presentation more effectively.
9.2.2: Communicating Examples
Examples help the audience understand the key points; they should be to the point and complement the topic.
Learning Objective
Use examples to help your audience understand the message being presented
Key Points
- Examples are essential to a presentation that is backed up with evidence, and they help the audience effectively understand the message being presented. An example is a specific situation, problem, or story intended to help communicate a more general idea.
- One method of effectively communicating examples is by using an example to clarify and complement a main point of a presentation.
- A speaker should be careful to not overuse examples, as too many examples may confuse the audience and distract them from focusing on the key points that the speaker is making.
Key Terms
- phenomenon
-
A fact or event considered very unusual, curious, or astonishing by those who witness it.
- abstract
-
Difficult to understand; abstruse.
Communicating Examples
Examples are essential to a presentation that is backed up with evidence, and they help the audience effectively understand the message being presented. An example is a specific situation, problem, or story intended to help communicate a more general idea. Examples are most effective when they are used as a complement to a key point in the presentation and focus on the important topics of the presentation.
Giving an Example
An example can make an abstract idea clearer.
Using Examples to Complement Key Points
One method of effectively communicating examples is by using an example to clarify and complement a main point of a presentation. If an orator is holding a seminar about how to encourage productivity in the workplace, he or she might use an example that focuses on an employee receiving an incentive (such as a bonus) to work harder, and this improved the employee’s productivity. An example like this would act as a complement and help the audience better understand how to use incentives to improve performance in the workplace.
Using Examples That Are Concise and to the Point
Examples are essential to help an audience better understand a topic. However, a speaker should be careful to not overuse examples, as too many examples may confuse the audience and distract them from focusing on the key points that the speaker is making.
Examples should also be concise and not drawn out so the speaker does not lose the audience’s attention. Concise examples should have a big impact on audience engagement and understanding in a small amount of time.
9.3: Using Statistics
9.3.1: Understanding Statistics
Statistics can be a powerful tool in public speaking if the speaker appropriately explains their use and significance.
Learning Objective
Use appropriate statistics in your speech in a way that is easy for your audience to understand
Key Points
- Understanding statistics requires creating a persuasive narrative that explains the data and an adequate explanation of why a statistic is being used, what it means and its source.
- The persuasive use of statistics is one of the most powerful tools in any rational argument, especially in public presentations.
- There are many ways to interpret statistics, however a public speaker should be mindful that they are presenting a statistic in an accurate way and not misleading the audience through a misrepresentation of a statistic.
Key Term
- statistics
-
A systematic collection of data on measurements or observations, often related to demographic information such as population counts, incomes, population counts at different ages, etc.
Understanding Statistics
Using statistics in public speaking can be a powerful tool. It provides a quantitative, objective, and persuasive platform on which to base an argument, prove a claim, or support an idea. Before a set of statistics can be used, however, it must be made understandable by people who are not familiar with statistics. The key to the persuasive use of statistics is extracting meaning and patterns from raw data in a way that is logical and demonstrable to an audience. There are many ways to interpret statistics and data sets, not all of them valid.
Guidelines for Helping Your Audience Understand Statistics
- Use reputable sources for the statistics you present in your speech such as government websites, academic institutions and reputable research organizations and policy/research think tanks.
- Use a large enough sample size in your statistics to make sure that the statistics you are using are accurate (for example, if a survey only asked four people, then it is likely not representative of the population’s viewpoint).
- Use statistics that are easily understood. Many people understand what an average is but not many people will know more complex ideas such as variation and standard deviation.
- When presenting graphs, make sure that the key points are highlighted and the graphs are not misleading as far as the values presented.
- Statistics is a topic that many people prefer to avoid, so when presenting statistical idea or even using numbers in your speech be sure to thoroughly explain what the numbers mean and use visual aids to help you explain.
Common Uses of Statistics in a Speech
Some common uses of statistics in a speech format may include:
- Results from a survey and discussion of key findings such as the mean, median, and mode of that survey.
- Comparisons of data and benchmarking results—also using averages and comparative statistics.
- Presenting findings from research, including determining which variables are statistically significant and meaningful to the results of the research. This will likely use more complicated statistics.
Common Misunderstandings of Statistics
A common misunderstanding when using statistics is “correlation does not mean causation. ” This means that just because two variables are related, they do not necessarily mean that one variable causes the other variable to occur. For example, consider a data set that indicates that there is a relationship between ice cream purchases over seasons versus drowning deaths over seasons. The incorrect conclusion would be to say that the increase in ice cream consumption leads to more drowning deaths, or vice versa. Therefore, when using statistics in public speaking, a speaker should always be sure that they are presenting accurate information when discussing two variables that may be related. Statistics can be used persuasively in all manners of arguments and public speaking scenarios—the key is understanding and interpreting the given data and molding that interpretation towards a convincing statement.
9.3.2: Communicating Statistics
Visual tools can be an effective way of incorporating statistics in your persuasive speech.
Learning Objective
Illustrate your argument by incorporating accurate statistics via visual tools.
Key Points
- Your audience is much more likely to believe you if you incorporate statistics.
- Consider using visual tools such as tables, graphs, and maps to make statistics more understandable for your audience.
Key Term
- statistics
-
A systematic collection of data on measurements or observations, often related to demographic information such as population counts, incomes, population counts at different ages, etc.
Using Visuals
Statistics is the study of the collection, analysis, interpretation, presentation, and organization of data.
Because data represent facts, incorporating statistics in your persuasive speech can be an effective way of adding both context and credibility to your argument. Your audience is much more likely to believe you if you incorporate statistics.
Statistics can be difficult to understand on their own, though. As a result, consider using visual tools such as tables, graphs, and maps to make statistics more understandable for your audience. These visuals are often easier to understand than raw data.
Using a Map
A map, a type of visual representation, can make data easier for the audience to understand.
9.4: Using Testimony
9.4.1: Expert vs. Peer Testimony
There are two types of testimony: expert testimony and peer testimony.
Learning Objective
Differentiate between expert testimony and peer testimony
Key Points
- A testimony is an assertion made by someone who has experience or knowledge of a particular matter.
- Expert testimony is testimony given by a person who is considered an expert by virtue of education, training, certification, skills, and/or experience in a particular matter.
- Peer testimony is given by a person who does not have expertise in a particular matter.
Key Terms
- Expert testimony
-
Testimony given by a person who is considered an expert by virtue of education, training, certification, skills, and/or experience in a particular matter.
- Peer testimony
-
Testimony given by a person who does not have expertise in a particular matter.
- testimony
-
An assertion made by someone who has knowledge or experience in a particular matter.
Introduction
A testimony is an assertion made by someone who has knowledge or experience in a particular matter.
Testimony is used in various contexts for a wide range of purposes. For example, in the law, testimony is a form of evidence that is obtained from a witness who makes a solemn statement or declaration of fact.
There are two major types of testimony: peer testimony and expert testimony.
Expert Testimony
Expert testimony, as the name suggests, is testimony given by a person who is considered an expert by virtue of education, training, certification, skills, and/or experience in a particular matter. Because experts have knowledge beyond that of a typical person, expert testimony carries considerable weight. Though an expert is an authority in a particular subject, his or her testimony can certainly be called into question by other facts, evidence, or experts.
Providing Testimony
Chairman of the Joint Chiefs of Staff Marine Gen. Joseph F. Dunford Jr. provides testimony to the Senate Armed Services Committee on counter-ISIL operations and Middle East strategy.
Peer Testimony
Peer testimony, unlike expert testimony, is given by a person who does not have expertise in the subject in question. As a result, those who provide peer testimony are sometimes referred to as “anti-authorities.”
A person who provides peer testimony might not have expertise in a particular area, but he or she likely has personal experience with the issue at hand. Though peer testimony can easily be challenged, it can still be a powerful tool in persuading an audience, particularly when delivered or provided by a well-liked celebrity.
Questions to Consider Before Using Testimony
Before incorporating testimony, ask yourself:
- Are you quoting the testimony accurately?
- Is the testimony biased? In what way?
- Is the person providing the testimony competent and/or well respected?
- Is the testimony current?
- How will your audience respond to the testimony?
9.4.2: How to Incorporate Expert Testimony
Expert testimony can be incorporated after introducing a point of your argument.
Learning Objective
State why it is beneficial to incorporate expert testimony into a speech
Key Points
- Expert testimony should be incorporated to support, defend, or explain the main point or subpoint of a speech.
- Limiting your main points, subpoints, and support points to three or four points each improves the ability for your speech to communicate with the audience.
- Noticing how professionals use the testimony of experts can provide creative examples for how to incorporate expert testimony into a speech.
Key Terms
- expert
-
A person with extensive knowledge or ability in a given subject.
- TED
-
Technology Entertainment Design, a series of global conferences.
Introduction
Once you have found experts to support your ideas, you may wonder how to incorporate their testimony into your speech. The following will give you an idea of how to incorporate expert testimony in order to support your argument and improve your speech.
What the Body of Your Speech Should Include
The body of your speech should help you elaborate and develop your main objectives clearly by using main points, subpoints, and support for your sub points. To ensure that your speech clearly communicates with your audience, try to limit both your main points and subpoints to three or four points each;this applies to your supporting points, as well. Expert testimony is considered supporting point; it is used to support the main and subpoints of your speech.
When a claim or point is made during a speech, the audience initially may be reluctant to concede or agree to the validity of the point. Often this is because the audience does not initially accept the speaker as a trustworthy authority. By incorporating expert testimony, the speaker is able to bolster their own authority to speak on the topic.
Therefore, expert testimony is commonly introduced after a claim is made. For example, if a speech makes the claim, “Manufacturing jobs have been in decline since the 1970s,” it should be followed up with expert testimony to support that claim. This testimony could take a variety of forms, such as government employment statistics or a historian who has written on a particular sector of the manufacturing industry. No matter the particular form of expert testimony, it is incorporated following a claim to defend and support that claim, thus bolstering the authority of the speaker.
Example of Incorporating Expert Testimony
Search for and watch a TED talk by Barry Schwartz, Professor of Social Theory and Social Action at Swarthmore College. Notice how Schwartz references expert testimony in the course of his speech to justify his point to the audience.
Barry Schwartz
Incorporating testimony from experts supports and clarifies claims made during a speech.
Schwartz begins by showing the job description of a hospital janitor, noting that the tasks do not require interaction with other people. However, Schwartz introduces the expert testimony of actual hospital janitors as a way to complicate the apparent solo nature of janitorial work. Schwartz personalizes the experts with proper names, “Mike,” “Sharleene,” and “Luke,” and uses their testimony to demonstrate that despite the job description, janitors take social interaction to be an important part of their job.
In this instance, Schwartz incorporates the expert testimony of actual janitors as a both a foil and a support. The testimony shows that in fact janitorial work does include interaction with other people, thus foiling the initial presentation of janitorial work as solitary. In addition, Schwartz uses the testimony of these experts to show that they embody the characteristics of wisdom that Schwartz will describe in the remainder of the speech.
9.5: Using Other Supporting Materials
9.5.1: Analogies
Analogies draw comparisons between ideas or objects that share certain aspects or characteristics, but are dissimilar in other areas.
Learning Objective
Define analogies and how they can be used as a linguistic tool in public speaking
Key Points
- Analogies compare something new and different (the main topic of a speech) to people, places, objects, and ideas familiar to audience members.
- Public speakers often use analogies to strengthen political and philosophical arguments, even when the semantic similarity is weak or non-existent.
- Analogies that begin with phrases including “like”, “so on,” and “as if” rely on an analogical understanding by the receiver of a message that includes such phrases.
- Considering audience demographics, and constructing similar rather than extreme analogies, are tactics public speakers use to create effective analogies.
Key Terms
- homomorphism
-
A similar appearance of two unrelated organisms or structures.
- iconicity
-
The state of being iconic (in all meanings).
- isomorphism
-
A one-to-one correspondence.
Example
- Some examples of analogies: the human eye is like a camera, love is a kind of game, sound waves are like the circular ripples that spread from a stone dropped in water.
Analogies
Analogies draw comparisons between ideas or objects that share certain aspects or characteristics, but are dissimilar in other areas. This cognitive process transfers information or meaning from one particular subject (the analogue or source) to another particular subject (the target) to infer meaning or prove an argument. In public speaking, analogy can be a powerful linguistic tool to help speakers guide and influence the perception and emotions of the audience.
Using Analogies
Analogies often use the structure “A is like B.” For example, the human eye is like a camera.
Analogies in Public Speaking
Linguistically, an analogy can be a spoken or textual comparison between two words (or sets of words) to highlight some form of semantic similarity between them. Thus, public speakers often use analogies to strengthen political and philosophical arguments, even when the semantic similarity is weak or non-existent (if crafted carefully for the audience).
Often presenters speak about topics, concepts, or places that may seem alien or abstract for audiences. To build trust and credibility on stage, speakers repeatedly link their main topic or argument to the values, beliefs, and knowledge of their audience. Demonstrating how the relationship between one set of ideas is comparable or similar to a different set ideas helps bridge this gap in understanding for listeners unable to formulate the relationship on their own. Likewise, analogies are sometimes used to persuade those that cannot detect the flawed or non-existent arguments within the speech.
The Construction and Role of Analogies in Language
Analogies that begin with phrases including “like,” “so on,” and “as if” rely on an analogical understanding by the receiver of a message that includes such phrases. Analogy is important not only in ordinary language and common sense (where proverbs and idioms give many examples of its application ), but also in science, philosophy, and the humanities. Presenters and writers also use analogies to enhance and enliven descriptions, and to express thoughts and ideas more clearly and precisely.
The concepts of association, comparison, correspondence, mathematical and morphological homology, homomorphism, iconicity, isomorphism, metaphor, resemblance, and similarity are closely related to analogy. In cognitive linguistics, the notion of conceptual metaphor may be equivalent to that of analogy.
Tips for Using Analogies
- Think about audience demographics. What are their interests, beliefs, and values? Choose a suitable analogy that the audience will be able to connect with and relate to.
- Keep analogies short and simple. Extreme analogies can weaken rather than strengthen an argument.
- Use analogies as a springboard rather than as the main focus of the presentation.
- Use analogies from personal experiences to create authenticity and credibility with the audience.
9.5.2: Definitions
It is easier to support your ideas when you provide definitions ensuring that you and your audience are working with the same meaning.
Learning Objective
State how defining key terms creates credibility for public speakers
Key Points
- Providing the definition of the key terms also works as a signal to your audience that you know what you’re talking about.
- In order to define the key terms, you first have to bluntly state what they are.
- Very often, you’ll use the work of somebody else to help you define the key terms.
Key Term
- concept
-
An understanding retained in the mind, from experience, reasoning and/or imagination; a generalization (generic, basic form), or abstraction (mental impression), of a particular set of instances or occurrences (specific, though different, recorded manifestations of the concept).
Example
- You can define fruit salad as consisting of bananas, pineapples, and yellow apples (ideally you would have a reason for this, too). Having done so, your audience will not object when you later state that fruit salad lacks the vital bits of red. Your definition of a fruit salad has supported this idea.
Introduction
During the introduction to your speech or presentation, you’ve given your audience a promise. You’ve told them that in exchange for their attention, you are going to deliver some information that answers the question which spawned the presentation in the first place.
Now you are giving the main part of your speech, and your audience expects you to deliver as promised.
There’s just one problem. Even though you’ve already decided what to include in the answer, you realize that there are times when the listeners may lose focus because they aren’t following you.
One way to make sure that your answer is focused is to tell your audience what you are talking about. In other words, define your key terms. In doing this, you do two things: First, you show that you know what you are speaking about. Second, you avoid misunderstandings by settling on a single understanding of the key terms. It might be that your audience understands power in a Marxist way, and you want to approach the presentation from a feminist point of view. By providing a brief definition, there will be no misunderstanding. Your audience may not agree with you, but that is not necessary to get your point across.
A definition makes sure you and your audience are talking about the same things.
For example, you can define fruit salad as consisting of bananas, pineapples, and yellow apples (ideally you would have a reason for this, too). Having done so, your audience will not object when you later state that fruit salad lacks the vital bits of red. Your definition of a fruit salad has supported this idea.
Using a Dictionary
A dictionary is the most obvious place to find definitions, but other sources can be used as well.
Providing Definitions
In order to define the key terms, you first have to bluntly state what they are. Always include the key words included in the question. These have been identified as central concepts for you, and by excluding them, you’ll be very likely answering a different question from the one set.
There are often other key terms you want to include, and it’s usually worth spending some time thinking about which ones are the key concept. The number of definitions you include will depend on the length of your speech. Sometimes it takes a bit of time to think which terms are the central ones. This is time worth spending, because you can later use the concepts without giving any further qualifications or comments. For this reason, you should also define the terms carefully.
Having defined “power” in a particular way, every time you use the term in the presentation, it will have the meaning you desire.
Providing the definition of the key terms also works as a signal to your audience that you know what you’re talking about. By defining “power” in a certain way, you demonstrate that you’re aware of other interpretations. In fact, it will usually not be necessary to state what the other interpretations are, unless the distinction is a key aspect of the argument.
It is easy to support your ideas once you’ve created credibility.
Examples
Very often, you’ll use the work of somebody else to help you define the key terms. The following two paragraphs define the concepts “social disadvantage” and “siblings. ” The definitions are taken from a range of sources, and referenced accordingly. In the context of another speech or presentation, these definitions may be too long or too short.
Social disadvantage, to start with, refers to a range of difficulties a person can be exposed to. According to McLanahan and Sandefur, social disadvantages include a lower expectancy in educational attainment, lower prospects at work, or lower status in society. Steinberg demonstrated that social and economic disadvantages in society often come together, leading some sociologists talking about underclasses. Social disadvantage, however, does not necessarily have to be as extreme as that: it describes a relative difficulty in reaching a similar position in society than people not disadvantaged.
Siblings, finally, in the context of this presentation, refer to brothers and sisters of the same birth family. This
means
that siblings are biologically related, as well as living in the same family.
9.5.3: Visual Demonstrations
Visual aids are often used to help audiences of informative and persuasive speeches understand the topic being presented.
Learning Objective
List the different ways visual aids add impact to a presentation
Key Points
- Visual aids are often used to help audiences of informative and persuasive speeches understand the topic being presented.
- The use of objects as visual aids involves bringing the actual object to demonstrate on during the speech.
- Models are representations of another object that serve to demonstrate that object when use of the real object is ineffective for some reason (e.g., the solar system).
- Maps show geographic areas that are of interest to the speech. They often are used as aids when speaking of differences between geographical areas or showing the location of something.
- Drawings or diagrams can be used when photographs do not show exactly what the speaker wants to show or explain.
Visual aids are often used to help audiences of informative and persuasive speeches understand the topic being presented. Visual aids can play a large role in how the audience understands and takes in information that is presented. There are many different types of visual aids that range from handouts to PowerPoints. The type of visual aid a speaker uses depends on their preference and the information they are trying to present. Each type of visual aid has pros and cons that must be evaluated to ensure it will be beneficial to the overall presentation. Before incorporating visual aids into speeches, the speaker should understand that if used incorrectly, the visual will not be an aid, but a distraction.
Planning ahead is important when using visual aids. It is necessary to choose a visual aid that is appropriate for the material and audience. The purpose of the visual aid is to enhance the presentation.
Objects
The use of objects as visual aids involves bringing the actual object to demonstrate on during the speech. For example, a speech about tying knots would be more effective by bringing in a rope.
- Pro: the use of the actual object is often necessary when demonstrating how to do something so that the audience can fully understand procedure.
- Con: some objects are too large or unavailable for a speaker to bring with them.
Models
Models are representations of another object that serve to demonstrate that object when use of the real object is ineffective for some reason. Examples include human skeletal systems, the solar system, or architecture.
- Pros: models can serve as substitutes that provide a better example of the real thing to the audience when the object being spoken about is of an awkward size or composure for use in the demonstration.
- Cons: sometimes a model may take away from the reality of what is being spoken about. For example, the vast size of the solar system cannot be seen from a model, and the actual composure of a human body cannot be seen from a dummy.
Graphs
Graphs are used to visualize relationships between different quantities. Various types are used as visual aids, including bar graphs, line graphs, pie graphs, and scatter plots.
- Pros: graphs help the audience to visualize statistics so that they make a greater impact than just listing them verbally would.
- Cons: graphs can easily become cluttered during use in a speech by including too much detail, overwhelming the audience and making the graph ineffective.
Maps
Maps show geographic areas that are of interest to the speech. They often are used as aids when speaking of differences between geographical areas or showing the location of something.
- Pros: when maps are simple and clear, they can be used to effectively make points about certain areas. For example, a map showing the building site for a new hospital could show its close location to key neighborhoods, or a map could show the differences in distribution of AIDS victims in North American and African countries.
- Cons: inclusion of too much detail on a map can cause the audience to lose focus on the key point being made. Also, if the map is disproportional or unrealistic, it may prove ineffective for the point being made.
Tables
Tables are columns and rows that organize words, symbols, and/or data.
- Pros: Good tables are easy to understand. They are a good way to compare facts and to gain a better overall understanding of the topic being discussed. For example, a table is a good choice to use when comparing the amount of rainfall in 3 counties each month.
- Cons: Tables are not very interesting or pleasing to the eye. They can be overwhelming if too much information is in a small space or the information is not organized in a convenient way. A table is not a good choice to use if the person viewing it has to take a lot of time to be able to understand it. Tables can be visual distractions if it is hard to read because the font is too small or the writing is too close together. It can also be a visual distraction if the table is not drawn evenly.
Photographs
- Pros: Photographs are good tools to make or emphasize a point or to explain a topic. For example, when explaining the shanty-towns in a third word country it would be beneficial to show a picture of one so the reader can have a better understanding of how those people live. A photograph is also good to use when the actual object cannot be viewed. For example, in a health class learning about cocaine, the teacher cannot bring in cocaine to show the class because that would be illegal, but the teacher could show a picture of cocaine to the class. Using local photos can also help emphasize how your topic is important in the audience’s area.[8]
- Cons: If the photograph is too small it just becomes a distraction. Enlarging photographs can be expensive if not using a power point or other viewing device.
Drawings or diagrams
Using a Diagram
Diagrams are used to convey detailed information.
- Pros: Drawings or diagrams can be used when photographs do not show exactly what the speaker wants to show or explain. It could also be used when a photograph is too detailed. For example, a drawing or diagram of the circulatory system throughout the body is a lot more effective than a picture of a cadaver showing the circulatory system.
- Cons: If not drawn correctly a drawing can look sloppy and be ineffective. This type of drawing will appear unprofessional.

The Power of Storytelling
Storytelling is a powerful tool, a means for sharing experiences and knowledge. It’s one of the ways we learn. Peter L. Berger says human life is narratively rooted, humans construct their lives and shape their world into homes in terms of these groundings and memories. Stories are universal in that they can bridge cultural, linguistic and age-related divides.

Presenters use narratives to support their points and make their speeches more compelling.
Learning Objective

How and When to Use Narrative
Whatever the purpose of your speech, you’re going to need a way to support your statements to prove their accuracy, but a good speech also makes its points interesting and memorable.
The most common forms of support are facts, statistics, testimony, narrative, examples, and comparisons. In this unit, we are going to address narrative .
Using a Narrative
Narratives can be used to support a point that has been made or is about to be made.
The Narrative
Narrative takes the form of a story. Presenters use narratives to support a point that was already made or to introduce a point that will soon be made. Narratives can be combined with facts or statistics to make them even more compelling.
How to Use a Narrative
- Storytelling points toward a single goal. Your story should not be forced, but should come across as a natural part of your speech. If your audience thinks you’re telling a story just because you read that it was a good idea to do so, your story won’t work.
- The task of a story is to make the audience care. Your narrative should be something that your audience can easily understand and relate to.
- Keep it short and sweet. Limit your narrative to three or four minutes at the most. Remember, you are using it to support or clarify your point. Once you’ve done that, move on.
- Your story is not there to replace information. It is there to put something you have said into perspective.
- The best stories paint a picture. They allow your audience to visualize what you are saying.
- Make sure your story builds over time and doesn’t get boring. Keep your audience interested until the end.
- Don’t overuse stories.
- Of course, as the old adage says, “use what you know.” Stories are not just about facts—they’re also about communicating what you have experienced and what you personally know, and feel, to be true.
