Presentation is an important process. It may seem difficult and even a bit intimidating, but it is one of the most valuable parts of the design activity. It gives you the opportunity to express you ideas and opinions about the design activity to others. It requires that you think about what you did and why. It helps you develop confidence and skill in reporting and presenting. These are considered among the most critical skills in the workplace.
One of the key things to do when presenting is to use you slides as talking points. One of the key things to not do is just read the slides. Everyone who sees them can read them. The best thing to do is to is to put key words a phrases in the presentation and tell the audience what they mean.
You will need to discuss, with your instructor, the format of the presentation and how to conduct it. A shared desktop process through Elluminate would seem a good starting point.
Activity
Actions you need to take
Give the presentation to the class
Make sure the presentation program is working well on your computer. Conduct several dry runs of the presentation by yourself, with someone at home, or with a few friends. That will help you get the 'bugs' out of it and help you learn it so that you don't get stuck unexpectedly.
