Southern Connecticut GeoGebra Conference

August 24, 2015

I’ll be giving a short presentation tomorrow at the 3rd annual GeoGebra Conference of Southern Connecticut. I’m really looking forward to meeting other folks in the GeoGebra community and hearing what they’ve been doing.

In my talk, I’ll be presenting an activity that I use in my Statistics class at Guttman. It’s based on APOS Theory, and uses a GeoGebra worksheet to help students make sense of the mean and median as objects. As students drag and drop dots on a dotplot, the mean and median dynamically change in response to their manipulations. The slides, handouts, and GeoGebra worksheet can all be found below.
