An effective talk require good preparation , presentation and question answering . The following notes should help you in this process.
Preparation Getting started in planning and preparing a talk is often the most difficult part.
Begin by determining the underlying concept of the talk, then choose the minimum essential material needed to support that concept. Develop this theme into one jargon-free sentence that will catch the attention of the audience. Working from an outline, write out the talk and practise it once or twice. Reorganise the material so the talk flows evenly, rephrase your statements as needed, and use a pencil to highlight key phrases. A short talk needs to be very clear and to address the topic directly.
