In order to present the best presentation and eliminate room for error, you need to keep in mind certain guidelines. Here are some of my ideas for presenting quality presentation that demand genuine attention from your listeners.

Picking out a topic is the hard part, when it comes to choosing from a list of presentation subjects. It has to be interesting, impactful and unique; therefore it is crucial to choose something you care about rather than randomly selecting one. Ask yourself if it covers angles-is it informative? Will it keep my listeners hooked? Will it create an air of boredom? Will I be able to get all my facts and research done? Is it appealing to me, but not to them?

There's nothing more annoying than having someone blabber on about a topic he/she hasn't done extensive research on. It is obvious from the way they speak, how monotonous their tones sound and how robotic their movement and gestures are. So don't be that someone. Take the effort to learn as much as you can. Make it matter to you, and remember how it can impact your listeners, and enlighten them on things they didn't know about at all.

84.

 
 

 
No one is perfect, and there are bound to be mistakes or circumstances that you didn’t count on and couldn’t avoid. You could stutter with a word, mix up slides, or forget some important sheets of your presentation and so on. Straighten up. Crack a minor joke in your defense. In other words improvise and don't beat yourself up about it or else your presentation will end in disaster. Don't let it ruin the rest of it, and finish the presentation as planned, so that people think more of how well it ended.

85.

 
 

 
The best thing about presenting a topic is eye contact. If you are able to say it by heart, and not by looking at a piece of paper, you will have mastered the most effective presentation technique. Memorize your lines, and points, and only glance at your notes occasionally if you think you may forget something. In the end, if you think that you are well prepared to answer questions, then by all means invite them.
