There are a million and one tips and tricks for using PowerPoint effectively, but what REALLY matters most? This presentation takes the 4 most important changes you can make to your presentations and explains simply how to go about them.
The focus is on use of images, making one point per slide, not using bullet points, and keeping things simple. Each of the rules is backed up by actual research, into multimedia learning principles, conducted at the University of California.
There's also several useful sites linked to, including 5 fantastic image resources, and a great place to download fonts.
