If it is pertinent, tell the audience how the data were obtained, especially if new or innovative methods were used. Explain what the data mean in relation to the overall seminar topic. Previously, you should have read the discussion parts of the research papers. The idea of giving an extemporaneous seminar frightens some students, but you are a professional and should learn to do this. Our seminar is invaluable for experience in presentation without reading.
Some students are good at memorizing, and can recite a seminar presentation perfectly.
Notes are acceptable and desirable if you need them. These can be words, phrases, or outlines to follow. Describe the information you wish to convey in your own words. You may make a statement or two about the relevance of these findings to other related subject areas. They usually contain so much material that your audience in the back of the room cannot decipher the values.
