Persuasive Speech Research

3 Research Steps to Successful Research When a Thesis Is Needed

Explore a topic, learn enough to understand the conversation surrounding it, and develop a focused question before searching for evidence for your persuasive speech.

Begin with Three Research Steps

Key Question

How do you move from a broad topic to a question that can support a persuasive thesis?

  1. Explore and pick a topic.
  2. Learn the basics of your topic: Who, what, when, where, and why. You should be able to talk for a minute, without repeating yourself, on your possible topic.
  3. Find an interesting question. It should not be too easy, too fuzzy, have too many parts, or be impossible to answer. It should require analysis and thought and should be debatable.

Why Learn About the Topic First?

When you participate in research or scholarship, you are entering into an ongoing conversation; you have to listen or read about that conversation before finding an interesting, relevant question. Many try to skip this step and end up frustrated. You wouldn't want to go up to two strangers on the street and join their conversation before you knew what they were talking about.

Bottom Line

Do not rush from choosing a topic directly into collecting evidence. Learn enough about the topic to identify a meaningful, debatable question first.

Develop a Research Question

Use the video below for additional guidance as you move from a general topic toward a research question.

Explore and Understand Your Topic

Key Question

What do you need to know before deciding exactly what you want to argue?

Start broadly. Explore the people, events, issues, perspectives, and terminology connected with your topic. This background research can help you discover a question worth investigating.

For additional guidance on AI-assisted exploration, see AI Tools for Research and Writing Success.

Brainstorm with Perplexity

Use Perplexity to generate possible directions for your persuasive speech.

Sample Prompt

I am interested in [your topic], and would like potential ideas for a persuasive speech. My goal is to change the minds or behavior of my audience in 5–7 minutes.

Use Exploration to Learn, Not Just to Choose

Explore several perspectives and background sources before settling on your question. The goal is to understand the conversation well enough to recognize an interesting issue you can investigate.

Resources for Exploring an Issue

Search Government Sources

For current information on the state of a particular issue or bill, try searching within the government domain online.

Practice Search

[your search term] site:.gov

Data use: Statistical data can provide tremendous support for your persuasive speech.

Search for Evidence

Key Question

What evidence and perspectives will help you investigate your tentative question?

Before you begin: Search for journal, magazine, and newspaper articles only after you have a tentative question and keywords.

Google Scholar

Google Scholar is a freely accessible search engine that indexes scholarly articles, theses, books, conference papers, and patents across various disciplines. It allows users to easily find academic literature, track citations, and access research materials, making it a valuable tool for students, researchers, and educators.

Academic Search Complete

Academic Search Complete contains more than 7,300 peer-reviewed journals. In addition to full text, this database offers indexing and abstracts for more than 12,500 journals and a total of more than 13,200 publications including monographs, reports, conference proceedings, etc.

LexisNexis Academic

Academic Universe provides access to nearly 5,000 publications on a wide range of topics: news, business, legal, and reference information. In Business, it includes company financials, SEC Filings and reports, directories, accounting journals & more.

Ethnic NewsWatch

Ethnic NewsWatch is a full-text collection of newspapers, magazines and journals of the ethnic, minority and native press. A rich collection of articles, editorials, columns, and reviews provide a broad diversity of perspectives and viewpoints -- the other sides of the stories. This resource is searchable in both English and Spanish.

Choose a Database for Your Subject

Bottom Line

Choose your search tool based on the kind of evidence your question requires. A focused question and useful keywords will make database searching much more productive.

Cite Your Sources

Key Question

How will you give appropriate credit to the sources that support your speech?

Purdue Online Writing Lab (OWL)

Great information on citing a variety of sources in APA, MLA, and Chicago styles. This site also includes a lot of good information on the writing and research process.

Citing References in Your Paper
