So how can you begin such a large task? The first step to take when brainstorming for any presentation should be preparing a storyboard. A storyboard is basically the first step in the presentation process that allows you to sketch out your ideas on paper. This process can be as detailed as you would like it to be by actually drawing out slides, images you would like to include and speaking notes for each slide.
Above is an example of a storyboard that was retrieved from( http://www.deniselynshue.com/storyboard.html)
This is a good example of a storyboard that was probably generated by some sort of computer program but this process can be as simple as grabbing a pencil and paper and physically drawing out each slide with appropriate comments. This should just be used as a starting ground for your project.
Next I want to talk about the actual powerpoint presentation or whatever software you plan on using when making your visual presentation. I think it is very important to keep things simple and only include key information that the listener will need to hone in on. If you do your due research and become very knowlegeable on the subject matter you have to be careful to not overload the presentation that will confuse the listener and make them lose interest. You want to include images and phrases that catch their attention and that you can elaborate on by speaking. You also need to be prepared to take questions at any time during the presentation as well as afterward. By taking questions you are ensured that someone is listening and interested in what you have to say. Making a successful powerpoint presentation can be very complex but remember sometimes simpler is better. There are many sites that will turn up when a powerpoint help search is done that will help you to establish what is proper presentation etiquette when drafting your design.
One last point I would like to make is the opening statements of the presentation. This is the time to catch your listener's attention so you can keep their attention throughout the presentation. I encourage you to do something different and unexpected that will catch their eye and attention. This is a time to be funny and witty, possibly even share a short story that leads into the content of your presentation.
So when you have to make an important presentation just remember that planning is essential. The more you practice and tweak your presentation the more comfortable you will become which will help to take away any nerves that you may have in front of your peers on the big day!
