Creating A Presentation on Copyright for Teachers

Trying to create a slide presentation for teachers on copyright was a challenge for someone like me, who has to thoroughly understand every point.  Copyright is not an tangible concept to easily grasp, and is in constant flux as the virtual world grows exponentially.  The article that we were assigned to read was very helpful, but I just found the organization difficult to follow.  I did learn a lot from it and it was the first time that I have ever heard of a creative commons.  I completed the powerpoint after numerous hours, most of my time spent reading, bullet listing, and tyring my hardest to abstract some concepts.
