Presentations are used for a variety of purposes. Most often, they are used to inform, teach, report, advertise, persuade, or inspire audience. Depending to the purpose of a presentation, its content, structure, and design may differ. Purpose of informative presentations is to inform about events or demonstrate some products, services, or product functions. While teaching presentations demonstrate how to do certain things: operate a device/tool or implement new process. Reporting presentations, on the other hand, convey status report of a project or process. Other common types of presentation in a business field are those that advertise, persuade, or inspire audience. Presentations focused on advertising target sales of products of services; persuasive presentations engage auditorium in decision making, while inspiring presentations engage into problem solving. When type and purpose of presentation are selected, presentation slides need to be designed with that purpose in mind. Slide design approach known as assertion-evidence (AE), is often used in the professional field. What is AE approach? Alley (n.d.) provides a clear outline of what AE approach is: This approach will help you to create better understood presentations, as evidenced by tests of audience comprehension. In addition, the approach will make your presentations more focused and help you to project more confidence. In the assertion-evidence approach, you build your talk on messages (not topics) to tell a coherent and compelling story about your work. Those messages you then support with visual evidence (not bullet lists). In addition, you engage the audience by fashioning sentences on the spot, but after practice. Presentations often contain visual elements that help to communicate a message or idea with less words. Those different visual elements are called presentation aids. Presentation aids include but are not limited to images/photographs, charts, tables, graphs, videos, audios, and special visual effects like animation. Prompt For this assignment, you will research the six types of presentation aids and write about three of them. Be sure to address the advantages and disadvantages of each of the three you choose. Then, add three visual aids to your own presentation that you prepared last week. Share your selections with your instructor. Your paper should be a minimum of 400 words with one citation.
