GeoGebra Ambassadors #3

Meet Steve Phelps from the USA.

Who are you, what are you doing?

I have been a secondary school mathematics teacher at Madeira High School in Cincinnati, Ohio, USA for the past 22 years. I have also been a Mathematics Instructor at the University of Cincinnati Blue Ash College in the Department of Mathematics, Physics, and Computer Science, as well as in the College of Arts and Science in the Mathematics Department for the past 10 years.

When did you first try GeoGebra?

I read an article by Markus on the Mathematical Association of America website in March of 2007. I have been using GeoGebra since that day. What was the “thing” that got me started? I was AMAZED how simple it was to do calculations with coordinates ( for example, x(A)+y(B) ). It was so difficult to do in other software 😉

What do you hate in GeoGebra?

I am not sure there is anything I hate in GeoGebra. There are some “I wish…” I think from time to time, you need to be a little “tech savvy” when in the rare instance a java issue crops up. I wish this was not the case. I think this can scare folks from time to time.

What do you love in GeoGebra?

How can I pick just one thing? Dani Novak from Ithaca College told me that he didn’t care if others used GeoGebra. He used GeoGebra because it made him happy. That is why I love GeoGebra…It makes me happy!

What are the GeoGebra related activities you participate?

I am the co-Founder and co-Director of the GeoGebra Institute of Ohio (GIOHIO), which was the first Local GeoGebra Institute in North America. We have organized the Midwest Regional GeoGebra conference for the past 2 years (attracting over 350 total participants) and will be hosting the 4th annual North American Conference in 2013.

On behalf of the GIOHIO, I run free GeoGebra workshops for teachers during the summer, as well as run free monthly GeoGebra workshops during the school year. I also share GeoGebra at State and National teacher conferences.
