It will make things far more interesting for the audience. Interact with the audience Be aware of how your audience is reacting. If they look confused, ask them why. Stop if necessary and explain a point again. If someone raises a hand, or asks a question in the middle of your talk, answer it.
Questions are good.
They show that the audience is listening with interest. They should not be regarded as an attack on you, but as a collaborative search for deeper understanding. Be ready to get the discussion going after your presentation. Just in case nobody has anything to say, have some provocative questions or points for discussion ready to ask the group. It is very helpful to use visual aids in your presentation, as it helps people to understand.
