I’ve included another TED Talk by Hans Rosling before, he’s worth another look. In the TED Talk below he uses some pretty simple software to highlight some interesting global economic issues and puts in a plug or two for making more data publicly accessible. Beyond learning more about global issues, I encourage you to watch how he presents. No boring Powerpoint presentations laden with words, too much text, and stupid animations here. He uses the presentation medium very effectively – heavily graphic, interesting story, well told. All teachers and public speakers can learn a lesson from Hans.
