Use visual aids. These do not need to be complicated or expensive. Even a simple picture gives the audience something on which to focus other than you. There are many types of visual aids available slides, pictures, charts, flip charts, overheads, demonstrations. Remember, a picture is really worth 1,000 words.
Some teachers are so busy moving from one visual to another that the audience gets lost.
Involve the audience. We all know how we feel about lectures. We like to feel that we are a part of the program. Add your own personality. Tell it in your own words.
