CA 110: Public Speaking: Choosing a Topic

Library resources for Public Speaking at the University of South Alabama

What is a topic? How do I know if my topic is good?

Every research project starts with a topic!

Your topic is the point of your speech. It is the subject that your speech covers.

  • What do you want to talk about?
  • Why should the audience pay attention?

A topic should have these qualities:

  • A topic has a scope. Your scope tells your audience what you'll talk about. It also helps you know if you've gone off track!
  • A topic has interest. Why should your audience care?
  • A topic can be researched and argued. Too basic question: How many hours of sleep does the CDC recommend for teenagers? More interesting question: Should parents limit teenagers' bedtime access to cellphones to promote better sleep?

As you research for your speech, your topic may shift. This is perfectly fine. Letting your topic naturally shift can help make sure that your claims are going to actually be backed by your research!

Structured Questions

You can create a research question, and explore a research topic, by answering structured questions related to an initial interesting topic. These questions help you choose a scope for your research question and will help you if you need to adjust your research question in the future. 

Questions are: 

  • Who? What populations or groups are involved in this concept? Are these people, plants, or animals? Who is affected by this phenomena? 
  • Where? Where does this event happen? Is there a specific physical environment? Do you want to limit your research to a state or a type of institution?
  • When? When does this event happen? Do you want to study a specific time frame? Do you have a decade you want to focus on? Is there a season or a time of day?
  • Why? Why does this event happen? What is an inciting factor? What effect or result do you want to focus on? Why does this topic matter to the population you are studying?
  • How? How does your topic happen? What factor do you want to focus on? How does your topic affect the world? 

The Mind Map

A mind map is a visual way of building a topic into a research question.

A topic is the basic idea that interests you. This is the idea that sparks your research. A topic could be "barbeque," "The Cold War," "flightless birds," or "the common cold." If you are having trouble choosing a topic, review the class syllabus or canvas modules. Find a topic covered in class that you can see yourself spending time with.

A research question is the focus of your research project. It is the thesis of your paper or the point of your presentation.

Work with us through the mind map steps to build your own research question.

To create a mind map, you will need to be able to write or type text, and the text must also be rearrangeable.

  1. Start with an idea like "Kitchen Design". Place your idea in the center.
  2. Photo of a desk with a card reading "Kitchen Design" in the middle.
  3. Surround your central idea with related concepts. I wrote all the kinds of kitchens I could think of. I could have also chosen to list appliances or design themes instead.
  4. Photo of a desk with cards listing kitchen types around a central card reading "Kitchen Design"
  5. Out of the kitchen-types, I was most drawn to "Hospital Kitchens". I then added concepts around "Hospital Kitchens". These concepts can be moved to also combined with other ideas.
  6. Photo of cards arranged in a mind map design
  7. I also thought more about "Home Kitchens". I combined, "Kitchen Safety", "Consumer Preferences", and "Advertisements."
  8. Photo of cards arranged in a mind map design
  9. My final version of my mind map example is very small. Don't worry if you have many more ideas and need more time rearranging your cards and planning.

I have identified two different starting research questions by combining my concepts:

  1. How could hospital managers design hospital kitchens to be safer for employees?
  2. How do kitchen appliance manufacturers advertise the safety of their products to consumers?

How do I choose a scope for my topic?

Your scope is how you limit your topic and research.

Giving a speech over WWII entirely would be impossible.

You can add a scope to your topic to limit it to something more possible. You don't have to limit your scope in all these ways. These are just filters you can apply to your scope like you apply filters to your online shopping results.

There are 2 major ways to change the scope of your topic.

  1. You ask yourself the Structured Questions again. Pay attention to what specifics you want to focus on.
  2. You use the scoping table. Add major nouns to the scoping table. 

Example: Women in WWII European front. (This is too large to cover in a short speech.)

Table for limiting the scope of a topic
Example Narrower Even Narrower
Women Nurses African-American Nurses
WWII Late in the war D-Day
European front Eastern Front France

You can always do some of your research, see what resources are out there, then shift your scope to fit the resources available. Sometimes, you can limit your scope too narrowly, and you find out that no one has done that research yet!
