NCTM 2012 Annual Meeting

NCTM 2012 Annual meeting and exposition was held April 25-28, 2012 in Philadelphia, PA. Cliff Konold delivered the invited, featured presentation: "Breathing Life into Data and Chance with TinkerPlots 2.0."

The photo shows Cliff (between the pillars of light) about 2 minutes before the start of the presentation. It was so popular, people had to be turned away, as you can see for yourself.
