Structure is important because a well organized presentation creates an impression that you know what you are talking about - you will gain the audience's trust and they will be more likely to listen to you.

The structure will help you become more comfortable during presentations and your audience will be more comfortable following this flow. There is a natural structure to presenting and the following structure formalizes this process.
To determine your purpose ask "What are the main points I want my audience to take away from my presentation?". This provides focus for you and the audience is clear on what they will gain by listening to your presentation.
It is important to identifies the characteristics, knowledge and needs of your audience so that you are delivering the 'right' presentation to the 'right' audience. Know who your audience is, what they want/need to know and what is their background (academic and otherwise). This step is done before the presentation and throughout.
Opening or Bridge
This is also known as the hook. It is designed to grab the audience's attention and provide them with a reason to be interested in the presentation.
Body of presentation
This is the major portion of the presentation. It is necessary that it connects directly to your purpose and bridge. Cover enough points to achieve your purpose (no more) and be sure to support your points, clearly and concisely. Remember to use transitions between your points.
This is the final impression you will leave with your audience - make sure it's a strong one. Connect back to your purpose and let them know where...
