Don t just list facts. Get rid of distracting idiosyncrasies. Ummms and Ahhhs have got to go. So does jingling coins in your pockets. Know your material.
Nothing beats having the material down pat.
If you do, it will cover a multitude of other problems that may arise. Get the audience to participate at varying levels if effective. You can use different methods, such as taking time to work alone or with a partner, feedback on certain points or questions and answers. Don t misinterpret people s response and get discouraged. You never know why a person may not be listening or get up and walk out.
