My long-time friend Art Bardige is a lifetime math educator, software developer, writer, university trustee, superb photographer, and much more. He does very visual, compelling presentations that tell a story. Art doesn’t worry about the number of slides, just how long it will take him to tell his story. The attached PowerPoint takes him abut 5.5 minutes to go through. You can see a narrated version in a video on the web site for his latest startup, WhatIfMath.org a 501-C3 non-profit that’s a vehicle for reinventing math education by using the spreadsheet as a learning lab.
This presentation tells the story of the history of math education. Even if you have no interest in math I think you will find it fascinating. Please note the spare use of text, the way visuals reinforce the text, and how the presentation is designed to support Art’s talk, not compete with it, as many over stuffed slide presentations tend to do.
