Alvin Trusty gives a presentation about PowerPoint and copyright. He starts off with some questions about copyright, dives into his PowerPoint tips and then talks about copyright in the United States.
I suggest watching this from start to end. Some of the PowerPoint tips are not new to the savvy but he has some nice ones about the use of colour and about transitions. He sprinkles his tips throughout the entire presentation, so look out for them!
While the copyright portion is about United States law, it is interesting to view, if only to get a feel for copyright issues educators face there. He also touches briefly on Creative Commons.
The presentation is 45 minutes long, but worth the watch.
