In a persuasive presentation you are acting as an advocate to bring about change in the attitudes, beliefs, or behaviors of your target audience. The purpose of the presentation is to change the attitudes or behavior of your audience about some issue or cause that your care about. Utilizing persuasive techniques such as emotional appeal, argument repetition, and credible evidence is encouraged.
You will need a research topic that is not too broad. You can start with a broad topic and narrow it down by thinking of some of the issues associated with it. Then turn your broad topic and issue into a debatable argument.
e.g. Sports:
Levels of sports: Professional Sports, Olympic Sports, College Sports, High School Sports;
Specific sports: Football, Baseball, Soccer, Horseracing etc.
Issues: Betting, Drugs and Doping, Health and Injuries etc.
Level of Sport + Specific Sport + Issue = Topic
Potential topics:
Should college athletes should get paid?
Is the NFL is doing enough to protect players long term health?
Would betting on college sports help the economy?
