Introduction. Getting started is probably the hardest part; it is when the nerves take over and you are most likely to fumble. Unfortunately, speakers commonly give less preparation to the talk’s introduction than other parts of the presentation. For the established researcher, credibility has been earned over many years of scientific contributions.In this situation, the audience will be forgiving of a deficient presentation style. For the not-yet-proven new researcher, credibility is often built in the first few moments. The introduction will set the stage for the rest of the talk.People are usually in the audience of their own free will. During the first few moments, you have the opportunity to convince them that this was a good choice. Conversely, if you stumble over words or do not use the occasion to provide a basic orientation, recapturing people’s attention will be very difficult.The introduction serves to provide focus
(statement of main idea), a reason to listen(significance of the main idea), and an orientation (division of the presentation).
