Getting Comfortable with Public Speaking

Prep:

  1. Part of getting comfortable with this skill is to take it one step at a time. Think about what should happen before a public speaking experience. Consider all the variables that might affect the actual speech situation. Make a list of the preparation process as you see it. Get some feedback on your list from a teacher or fellow student.
  2. Choose a subject you could effectively share with others. This could be a hobby, an area of study, something in your work assignment, or a current issue you've studied thoroughly. Make an outline to assist in making a presentation concerning this topic. If possible, get a person you trust to serve as an audience for your practice activity.

Observation Activities

  1. Study a specific example of public speaking that occurs in your everyday world. It isn't hard to find examples all around us—maybe a school principal or teacher at a school assembly, a pastor or rabbi, or a community meeting in your neighborhood. Evaluate what you observe about the situation. Does the speaker seem anxious? Is their material well-organized? How does the audience react to what is said?
  2. Watch an interview-type show on television or online. Both people involved in the conversation are public speakers at that time. How prepared is the interviewer? How about the person being interviewed? See what you can learn from your observation that might help you sometime when you are in front of a crowd or a camera.

Note to Instructors

The main take-away from this lesson and these activities is to help the student be more aware of public speaking situations that happen all around us in the 'real world.' Observing is a prime learning activity in a performing type of skill. Then comes planning and finally practicing the skill. If possible, give students an opportunity to practice speaking in public in a safe-feeling environment.

What is public speaking?

Public speaking is a form of communication that includes a presenter and an audience. It is more formal than casual conversation and requires an organization of thoughts with a specific purpose or goal in mind.

What is the importance of public speaking?

Public speaking is a tool used for conveying information. The purpose of public speaking can vary and may include simply sharing information. Other purposes of public speaking include motivating, celebrating, and persuading others.

Public speaking is the art of conveying information to an audience through oral presentation. It is an act of communication and dates back to the times of ancient Greece. The purpose or intention of public speaking varies and can include informing, motivating, celebrating, entertaining, and persuading. Public speaking involves a presenter (the person speaking) and an audience (the people listening).


Public speaking involves a presenter and an audience. The size of the audience can vary but consists, generally, of at least 8 people.

There are several specific elements of public speaking that include:

  1. the speaker
  2. the message
  3. the audience
  4. the channel
  5. the effect(s)

The speaker refers simply to the person who is presenting, and the message is the content being presented. The audience is the intended recipient of the message. These three elements are sometimes referred to as who, what, and whom.

The channel is the medium used to the share the message--it is how the message gets sent. The effect is the result of the message having been sent and received. The effect is not necessarily consistent with the speaker's goal.

Public speaking is a more formal type of communication as opposed to small talk or other informal conversations. Public speaking requires preparation and organization.

History of Public Speaking

The art of public speaking has a long history dating back to ancient Greece and ancient Rome. The timeline includes the Classical Period from 500 BCE to 400 BCE. During this time, the ancient Greeks valued public debate as well as civic and political engagement, and scholars dedicated much time and energy to each. Socrates, Plato, and Aristotle are some of the Greek philosophers who advanced the study of the rhetoric. Aristotle is best known for his three persuasive proofs that include ethos (speaker credibility), pathos (emotional appeal), and logos (logic). Cicero, an ancient Roman philosopher, identified the five canons of rhetoric, a series of steps to follow when creating a persuasive public speech.

Public speaking is important to both the presenter as well as the audience. From a presenter's perspective, public speaking can serve as a method of sharing information and potentially persuading others. From an audience's perspective, it can be an opportunity to learn and better understand. The results of effective public speaking can include enlightenment and change as well as unification and empowerment. It can serve as a tool to change attitudes and behaviors or to reaffirm the status quo.

The ability to effectively present what one is thinking and feeling through public speaking can impact one's confidence level. Improving one's public speaking abilities can actually increase self-confidence.

The art of public speaking is a means of conveying information and, potentially, changing how people think (and even behave). It is a formal and organized method of communication with a presenter, message, audience, channel, and effect. The presenter is the source of information and sometimes referred to as the who. The message is what is communicated and also referred to as the what. The audience is the intended recipient of the message and sometimes referred to as whom. The channel is how the message is communicated, and the effect is the impact or result.

Video Transcript

What Is Public Speaking, Anyway?

Think about a time that you had to stand in front of a bunch of people and tell them something. Maybe it was an oral report in grade school or a proposal at work. After gathering your materials and preparing what to say, you arrived at the podium and started talking.

That, my friend, is public speaking, and it involves communicating information before a large audience. What makes public speaking different than, say, just talking to a crowd of people, is in the way information is conveyed. In public speaking, the information is purposeful and meant to inform, influence or entertain a group of listeners.

There are five elements of public speaking, and it basically boils down to who is saying what to whom using what medium with what effect. In other words, who is the source of the message. What is the message itself. Whom is the audience, while the medium is the actual delivery method and ending in the effect. Think of the effect as the speaker's intent for the speech.

Public speaking dates back centuries, yet still remains one of the most important skills we can acquire in modern times. So, why is it so important to know?

Why Do We Need to Do It?

So, you're thinking of a time when you had to present something in front of a group. And the only memory you have might be of sweaty palms and knocking knees. There are some very good reasons why you need to know how to do it. Actually, there are so many reasons why everyone should learn how to speak in a public forum. Let's check out a few:

  • Every time you speak in public, it increases your self-confidence
  • As we become comfortable speaking, we become more comfortable around people
  • We can reach a large audience in a shorter time than having individual conversations
  • It's a great way to show how much you know about a subject
  • You can build a fan base of followers
