This is a great resource for teaching students how to create neat, clean, and informative Powerpoint (or Keynotes) presentations.
This 21-slide presentation explains how to setup a presentation so that the audience stays engaged and isn't overwhelmed with information.
It discusses how to design a presentation using appropriate pictures, text, and animations, and gives examples of "DOs" and "DON'Ts" for each tip.
This is a perfect introduction to any media or research-based project!
